Quick Guide

Levelling the Bed

1. Squeeze each corner of the printing bed, and tighten each wing nut to reduce the distance

between plates to a minimum. Wipe the top of the Heated Print Bed with a clean, lint-free
cloth to ensure no dust particles or other objects are on the Heated Print Bed. Remove all the
white tape covering the X, Y, Z axis stop micro switch prior to the next step

2. Using the switch on the back of the Control Box, turn on the WANHAO 3D Printer.
Once initialised, press the Navigation Dial to enter the menu system. Navigate to and select
Position then select Home All. Your 3D printer will now try to align to the home position, on
the front left corner of the Heated Print Bed. Once aligned, turn off the 3D printer

3. With the printer powered off, check the Z axis level. The X rail should be parallel to the Heated
Print Bed. If it is not, manually rotate the right hand side Z axis stepper motor to level it

4. Manually move the Extruder to one corner of the Heated Print Bed to check the distance
between the nozzle and Heated Print Bed. Rotate the wing nut to raise the Heated Print Bed.
The distance between the Extruder and bed should be 0.1mm or roughly the thickness of
an A4 sheet of paper. The paper should have very slight friction as you move it under the
Extruder but should still slide freely

5. Move the Extruder to each of the other corners and repeat the process. Move the Extruder to
the centre of the Heated Print Bed and test the gap with a sheet of paper. Keep adjusting and
testing until the gap is uniform on all points of the bed

Introduction

1.1 What is 3D Printing?

3D Printing is a process whereby a real object is created from a 3D Design. Fused Filament
Fabrication (FFF) is one of the most common technologies used by 3D Printers to achieve this. FFF

works on an ‘additive’ principle by laying down material, such as PLA or ABS lament, in layers to

create a 3D object.

1.2 From 3D Design to Printed 3D Object:

3D Design Slice to GCODE Setup 3D Printer 3D Printing Process 3D Printed Object

3D Design

Having a 3D Design is the rst step to creating a 3D Object. There are

a number of free 3D Designs that can be downloaded and printed for

personal use. Websites such as Thingiverse.com, Pinshape.com and

YouMagine.com are a good place to start, but there are many more

available!

Alternatively, you can create your own 3D Design using 3D Modelling Software. Programs such as

SketchUp or Blender allow this, however this can take some practice before successfully modelling

your 3D Design. After you’ve nished your 3D Design, you can export it as an .STL le, to be

imported into a ‘Slicer’ program such as Cura.

Slice to GCODE

A ‘Slicer’ converts a 3D Design (usually in .STL or .AMF format) into

individual layers. It then generates the machine code (such as GCODE) that

the 3D Printer will use for printing.

We recommend Cura, as it uses a simple interface and includes a large amount of support material.

Introduction

Setup 3D Printer

It’s important to set up your printer before every print. We’ve included some

steps on page 20 in section 1.3 ‘Good 3D Printing Practices’ for you to quickly

refer to each time.

3D Printing Process

Now that you’ve loaded a GCODE le onto the printer, it will commence

heating up the Extruder and Heated Print Bed, then start printing. While

printing, the nozzle will move along the X and Y axis as each layer is printed.

This can take some time, depending on the size of the 3D model, print speed

of the 3D printer and resolution of each layer.

Here is an example of how size, inll, and resolution can effect printing time:

Dimensions:

Inll:

Resolution:
Print Time:

Filament Used:

3D Printed Object

Once the printer has completed all of the layers, you will have a 3D Printed Object. The results are
certainly worth it, with 3D models ranging from simple to complex.

The WANHAO 3D Printer is compatible with a broad range of lament types and is capable of

printing 3D models ranging from small and simple to complex objects with moving parts. What you
print is limited only by your imagination.

Introduction

1.3 Good 3D Printing Practices

Please refer to these steps during every print to ensure the best quality.

Before Printing

1. Ensure your GCODE le is correctly setup, lament diameter is set to to 1.75mm and correct

temperature settings for the material you are using (refer to table 3.1, page 27)

2. Check all cables and connectors are connected

3. Check that Heated Print Bed is level and approximately 0.1mm from the nozzle

4. Check that Heated Print Bed is clean and dust free and nozzle does not have excess material

stuck to it

Always check Gcode

le settings match

lament and printer

Always check

Print Mat is clean

and there is no

residual plastic

Always check Extruder

& Print Bed

Temperatures are set

for correct lament type

Always check all

cords are

connected

Always check

Extruder distance is

0.1mm from Print Mat

Always check

Print Bed is level

During Printing

1. Closely monitor the rst layer being printed – Most problems will occur in the rst layer. If

problems occur, stop the 3D Printer at the power outlet

2. Do not leave the 3D Printer unattended while in operation

3. Keep hands clear while machine is operating

After Printing

1. Wait for the Heated Print Bed and Extruder to cool down

2. Carefully remove 3D Object. Never use Scraper towards your body. Keep Scraper evenly at

when scraping to avoid damage to the Heated Print Bed. Damaged Heated Print Bed will
affect adhesion for future prints

3. Store 3D printer in a clean, dry environment

Setup

2. Levelling the Heated Print Bed

It is important to ensure the Heated Print Bed is level and set to approximately 0.1mm distance
prior to printing.

1. With the printer initialised, press the Navigation Dial to enter the menu system

2. Rotate the Dial until Position is highlighted, then press the Dial to select

3. Rotate the Dial until Z. Pos. Fast is highlighted, then press to select

4. Rotate the Dial clockwise, raising the Extruder so that you can easily access the Heated

Print Bed

5. Turn off your 3D Printer

6. Check the Z axis level. The X rail should be parallel to the Heated Print Bed. If it is not,

manually rotate the right hand side Z axis stepper motor to level it

7. Squeeze each corner of the Heated Print Bed, and tighten each wing nut to reduce the
distance between plates to a minimum

8. Wipe the top of the Heated Print Bed with a clean, lint-free cloth to ensure no dust particles or
other objects are on the surface

9. Turn on the 3D Printer, using the switch on the back of the Control Box

10. With the printer initialised, press the Navigation Dial to enter the menu system

11. Navigate to and select Position > Home All. Your 3D printer will now try to align to the ‘home’

position, on the front left corner of the Heated Print Bed

12. Once aligned, turn off the 3D printer

13. With the printer powered off, move the Extruder to one corner of the Heated Print Bed to

check the distance between these components

14. Rotate the wing nut to raise the Heated Print Bed. A good distance is 0.1mm, and will allow a
sheet of paper to slide freely with slight friction between the Extruder and Heated Print Bed

15. Move the Extruder to each of the other corners and repeat the process. Move the Extruder to
the centre of the Heated Print Bed and test the gap with a sheet of paper. Keep adjusting and
testing until the proper gap is present at all points

IMPORTANT NOTE: Levelling the bed is an extremely important step and if it is not done
correctly every time, your prints will fail or be of poor quality

3.3 Removing Filament:

1. With the printer initialised, press the Navigation Dial to enter the menu system.

2. Navigate to, and select Quick Settings > Preheat PLA or Preheat ABS depending on the

material.

3. Wait for the 3D printer to automatically return to the home screen, after approximately 15-30
seconds.

4. Check the temperature of the Extruder and plate on the LCD. When the temperatures are

within a few degrees of the target, you are ready to remove the lament.

NOTE: Preheat PLA/Preheat ABS will still be shown, even after temperatures have been reached.

5. Depress the Extruder spring lever. Push down on the lament gently so that it starts to

extrude from the nozzle.

6. When lament is extruding, quickly, but gently pull the lament upward. If it is done correctly,
the end of the lament will pull out into a thin hair like strand.

NOTE: The aim is to sever the lament where is it soft (inside the nozzle). Swift upward action will
ensure that the lament does not cool down before exiting the nozzle inlet. If the lament gets

stuck, please see the troubleshooting section.

3.4 Storage:

Both PLA and ABS laments are sensitive to moisture. If stored in a humid environment, the quality
of the lament can deteriorate, with a tendency to bubble and spurt from the nozzle tip. This will

affect print quality, so when storing PLA or ABS for an extended period of time, follow these tips.

• Store in a sealed, air tight bag/container. We recommend a vacuum seal bag

• Store with a silica gel (moisture absorber) pack. One is included with each lament spool

4. Using the Micro SD Card

4.1 Loading les from your Computer:

1. Insert your MicroSD Card into a card reader or memory card slot and connect to your
computer (refer to your computer manual for further instructions if required)

2. The Micro SD Card will appear as a folder (refer to your computer manual for further
instructions if required)

3. Copy your converted GCODE les to the Micro SD card, then safely remove

4.2 Printing from the Micro SD Card:

1. Insert the included MicroSD card into the slot on the side of the Control Box, ensuring that

the metal contacts are facing upwards

2. Press the Navigation Dial to enter the menu system

3. Navigate to and select SD Card > Mount Card > Print File

4. Navigate to your desired GCODE File, then press the Dial to commence printing

Your WANHAO 3D Printer will now heat up the Extruder and Heated Print Bed before
printing your 3D object

NOTE: If selecting ‘Print File’ shows no les, chances are the SD Card has not been mounted. Select

‘Unmount SD Card’, then ‘Mount SD Card’ to remount your SD Card into the side of your Control Box

NOTE: If Extruder temperature is set at 0°C after attempting to print a le, the imported GCODE may

have some compatibility issues with the printer. Manually change the Extruder temperature using

Extruder > Temp 1 or Quick Settings > Preheat PLA or ABS depending on material used

5. Removing 3D Objects from the Bed

When the WANHAO 3D Printer has completed printing your 3D printed object, it’s time to
remove the object from the bed.

1. Wait until the Extruder and Heated Print Bed have cooled down to room temperature. This
will allow the plastic to contract, making it easier to remove

2. Using the Scraper, carefully ‘wedge’ under one of the edges of the 3D object. Take care

tokeep the Scraper at with the bed, as to not cause damage to the Print Mat

3. As one edge begins to lift, gently manoeuvre the Scraper forward to continue to ‘wedge’
between the 3D object and the Heated Print Bed

4. Once the part has fully separated from the bed, it is safe to remove

NOTE: Never scrape towards your body, or injury could occur

NOTE: Removing a 3D object, particularly one with a large surface size, can be a long process.

Never rush when removing a 3D printed object

TIP: If you are persistently having trouble removing 3D printed objects, try the following:

• Use a layer of blue masking tape (designed to not leave behind residue) on the Heated Print

Bed. Be sure to remove and replace after each print

• Check if the printing mat is damaged and replace if needed

Rotate

The Rotate button will give you the ability to orient your model in along all three axes. Once you
click the rotate button, three circles will surround your model. The red circle will allow you to rotate
around the Z axis. The Yellow circle will rotate around the Y axis. The Green circle will rotate around
the X axis.

Lay Flat

The Lay Flat button will ensure that the at portion of your print is securely attached to the bed.

It is highly recommended to use this option after rotating your model in the Z direction, as it will
help prevent adhesion issues during the print.

Reset

The Reset button will return your model to the original orientation as dened by the CAD program

used to create the model.

Scale

The Scale button displays the model dimensions, along with the ability to scale along the X Y or
Z axes. Anything below the number 1.0 will reduce the objects size, while anything above the
number 1.0 will increase the objects size. As a default, it will be set to uniform scaling. This will
cause the X Y and Z axes to be scaled by the same amount when you make a change to any of
them. To disable this, select the lock in the lower section of the scaling window.
TIP: Ensure your model is selected by left clicking on it. When selected, the model will have a
white outline

6.5 Quick Print Settings

Quick Print mode allows you to quickly set the quality, material,

diameter and support structure of your intended GCODE le.

Enter quick print mode by selecting Expert > Switch to Quickprint…

High Quality

Designed to give greater detail and ner objects. This will have a smaller

layer height, which will make each layer thinner, so that curves seem
more natural and walls seem less noticeable.

Medium Quality

Designed to give a medium resolution, by increasing the layer height and print speeds. This will

make the organic curves slightly more step-like than the ne setting, but will reduce printing time.

Fast Quality

Designed for the fast prints, where overall model nish is not of concern. Most commonly used for

quick iteration of designs found in rapid prototyping.

Material Selection

Choose your desired lament. The WANHAO 3D Printer includes a 10 metre sample of PLA to
be used in your rst print.
Other laments are available for purchase at id.aliexpress.com/store/120824

Diameter

Ensure this is always set to match the lament diameter. Your 3D Printer only accepts WANHAO

1.75mm laments.

NOTE: Advanced users can ne tune the diameter value to allow for tolerance if needed

Printing Support Material

Your WANHAO 3D printer is able to print models that have angles and overhangs, some of

these models will require support material depending on the overhang distance and angle. Turn

this option on if your model could benet from support material.

6.6.1 Basic Tab Options

QUALITY

Layer Height (mm)

The thickness of each printed layer is known as the Layer
Height. The smaller the layer height, the smoother curves
will appear. Larger layer heights are better for bridging and
overhangs. Smaller layer heights will also increase print
time, as it will take more layers to complete the object.

er.

Shell Thickness (mm)

This denes the number of vertical walls that comprise the

outside of your model. We recommend keeping this set to
multiples of your nozzle width. Your WANHAO 3D Printer is equipped with a 0.4 mm nozzle.

Enable Retraction

Retraction tells your printer to pull lament out of the Extruder upon travel moves. Travel moves

are when your print head moves from one area of the print, to another without laying down

lament. We recommend keeping this on for all lament types, and adjusting the retraction length
and speed for the specic lament.

FILL
Bottom/Top Thickness (mm)

Also known as Surface Layers; this will determine how thick the top and bottom layers are. A larger
number here will create a thicker top and bottom which can be helpful for strength, bridging, and
quality purposes. We recommend using a number which is a multiple of your layer height.
Eg: If using a layer height of 0.2mm, set the thickness to 0.4, 0.6 or 0.8mm

Fill Density (%)

This number is expressed as a percentage. 0% will give a completely hollow print, while 100% will

give you a completely solid object. We recommend 20% to 40% ll density as it is functional for

most prints.

SPEED AND TEMPERATURE
Print Speed (mm/s)

Your overall printing speed can be adjusted here. If no other speeds are determined in the
later sections your printer will automatically default to this speed. This speed will be different,

depending on what type of lament you are using. We recommend setting speed to 30mm/s.

Printing Bed Temperature (C)

When using different lament materials, you’ll need to update the desired Extruder and Heated
Print Bed temperature. Any temperatures specied here will be used to automatically set both

the
Extruder and Heated Print Bed. Your print will not begin until these temperatures are met. As a
guide, refer to Table 3.1 on page 27 for temperature settings.

SUPPORT
Support Type

Some models will require support material in order to print properly. This will usually occur when
an object has an angle in relation to the Heated Print Bede between 0 to 45 degrees. It is highly
recommended to orient your object so that it minimizes or eliminates the need for support.

Touching Buildplate

This causes the support material to build up between the Heated Print Bed and the object.
The red example is ‘Touching Buildplate’

Everywhere

This prints support material between the Heated Print Bed and object as well as between
the object and itself. The green example is ‘Support Everywhere’.

Platform Adhesion Type

Some models have a small surface area contacting the plate. This can create adhesion issues

causing your part to pop off at some point during the print. To x this, use either ‘Brim’ or ‘Raft’.

Raft is better used when a model has small contact points with the Heated Print Bed and
overhangs.

Brim

Brim will create a single layer of lament, contacting and surrounding your model. This will

increase the surface area of the part contacting the build platform thereby preventing it
from popping off the Heated Print Bed. Brim will also help in situations where you are seeing
corner lift.
Brim settings can be adjusted by selecting ‘...’ next to the tab.

Raft

Raft will generate a layer of material underneath your object. Raft was more often used
before the addition of heated plates to increase surface area. Raft settings can be adjusted
by selecting ‘...’ next to the tab.

FILAMENT
Diameter (mm)

The lament diameter setting is one of the more important settings. Make sure that you update
this value periodically with your average lament diameter. While your lament may be referred to

as 1.75mm, it is more likely going to be near 1.7mm +/- 0.1mm. You will want this to be an accurate

average, as it will allow your printer to correctly calculate how much lament it is pulling into the

Extruder.

Flow (%)

This controls how much lament your printer is extruding in relation to speed. This setting is
mainly used to adjust for lament density variations. Leave this value at 100% as changing it can

lead to surface quality issues.

6.6.2 Advanced Tab Options

MACHINE
Nozzle Size (mm)

This denes your nozzle size. The slicing engine uses this value

combined with your other settings to determine how quickly

to feed lament into your Extruder. The WANHAO 3D

Printer uses a 0.4mm nozzle.

RETRACTION
Speed (mm/s)

Retraction Speed determines the speed at which your

lament is reversed out of the Extruder for travel moves and

when changing direction during printing. We recommend
keeping this set to 40mm/s.

Distance (mm)

Retraction Distance determines how much lament is pulled out of your Extruder on travel moves

and when changing direction. You will want to adjust this depending on temperature settings

and lament type. Higher thermal retaining laments such as PLA behave better with a longer

retraction distance. Anywhere from 1mm to 3mm is a good starting range.

QUALITY

Initial Layer Thickness (mm)

This will control how thick your rst printed layer height is printed onto the Heated Print Bed.

Having a larger initial layer height will help prevent your part from popping off the plate. Your
WANHAO 3D Printer auto levelling system could be affected if you change this from the

standard proles. Adjust at your own risk.

Initial Layer Line Width (%)

This will control how wide your rst extruded lament path is for the initial layer. A wider line

width will help with bed adhesion. We recommend 125% as a good starting place. For models with
moving printed in place parts, a smaller initial layer line width is recommended.

Dual Extrusion Overlap (mm)

This will determine how far your Dual Extruders will overlap when laying down material. This will

help adhesion between the two different colours or types of lament. This setting is not applicable

to the WANHAO 3D Printer, it is only for printers with dual Extruders.

SPEED
Travel Speed (mm/s)

This setting will determine how fast your print head moves while not extruding lament. A normal

travel speed of 125 - 150mm/s is recommended.

Bottom Layer Speed (mm/s)

This will control your initial layer speed. In general, a slower initial layer speed will help with rst

layer adhesion.

Inll Speed (mm/s)

This is how fast your print head speed will be while laying down the interior portion of your model.

Faster speeds are usually tolerable here, as none of the inll will be visible from the outside of your

object. However, if you go too fast compared to your inner and outer shells, you can have adhesion

issues or globs of lament left behind from the print head.

Outer Shell Speed (mm/s)

This will be the outermost surface of the model. This is the most important setting, as it controls
the speed of your print head on the visible layers. As a general rule of thumb, the slower you go the
better looking print you will get.

Inner Shell Speed (mm/s)

This affects vertical walls that are in between the outer shell and inll. This will not be visible but
will help support the outer shell and the inll. We recommend keeping this speed setting between
your inll speed and your outer shell speed.

COOL
Minimal Layer Time

This will determine a minimum amount of time your printer will spend laying down each layer. If
your layer print time falls below this your printer will automatically slow down to reach this time
before moving onto the next layer. Tweaking this can help get cleaner, crisper prints.

6.6.3 Plugins Tab

Plugins are custom settings which will alter your print at

specic points. The two that come pre-loaded with Cura

are Tweak at Z, and Pause at Height. More plugins and
information can be found here:

http://wiki.ultimaker.com/Category:CuraPlugin

To activate one of these highlight the desired plugin and
click the drop-down arrow directly below the Plugins box.

Tweak at Z

Make basic changes at specied Z heights. You can

determine the Z height or layer count at which you want to make a change. Then choose how
you would like to change your settings. You can alter temperatures, fan speeds, and print

speeds. Fine tuning these for specic STL les, can produce cleaner prints.

Pause at Z Height

Pause your print at a specied height. You can also specify where to move the print head
and how much lament to retract. This will prevent ‘blobs’ from accumulating on your print
while paused. This setting is most commonly used when switching colours of laments in the

middle of a print.

6.6.4 Start/End GCODE Tab

Custom Gcode allows for complex automatic printer
movements and operations. By adding custom Gcode into

the start or end of your le, you can alter how it prints. A

comprehensive list of Gcode commands can be found here:

6.6.5 Expert Settings

Expert settings will give you more specic options for your retraction, skirt, active cooling, inll,

support, brim, raft, and special settings. To gain access to this section you go to Expert > Open
Expert Settings or on your keyboard press Control + E.

Retraction

Retraction pulls lament out of your nozzle when it is not extruding to prevent your print head

from dripping on your object. This section is where you will control how your Extruder retracts its

lament.

Minimum Travel (mm)

This sets the minimum travel distance of your print head in order to retract. If your print

head is not moving this far during travel moves, it will not retract.

Enable Combing

This option prevents your print head from travelling over holes in the X/Y plane when

printing.

This will slightly increase print time, but will prevent strings from getting caught on the

holes during travel moves. We recommend keeping this setting on.

Minimal Extrusion before Retracting (mm)

This will control the distance at which retraction occurs if the printing movement exceeds

the minimum extrusion amount. This will prevent a retraction move, if your Extruder has not

put out Xmm of lament since its last retraction.

Z Hop When Retracting (mm)

This will raise your print head Xmm while retracting. This setting helps prevent ooze, and

strings from being deposited on your print.

Skirt

Skirt creates a line around the outside of your object. This is most commonly used to prime the

Extruder. In order to prevent missed lament at the beginning of a print, we recommend you leave

this setting on.

Line Count

This will dene the number of loops the Skirt creates around the outside of your object.

Smaller models will require more loops to properly prime the Extruder.

Start Distance (mm)

This will dene the distance away from your model that the skirt will be created. If using as an

envelope to prevent drafts, it is recommended to be closer to your object.

Minimal Length (mm)

This will dene the minimum extruded line length for the skirt. This will over ride your line

count, producing as many lines as required to reach the minimal length.

Cool

This section will dene how your Extruder cooling fan will operate during the print. Your fan will

not start until it has reached 25% or higher for speed settings. If your print speeds are slowed down
due to minimal layer time, the fan will run between minimum and maximum speed based upon
how much the layer is slowed down.

Fan on at Full Height (mm)

The fan will not turn on for the rst layer. The fan will then be scaled between 0% and your

minimum fan speed based on layer height. It is especially helpful with high temperature

retaining laments such as PLA.

Fan Speed Min (%)

Once the Z height is reached for Fan on at Full Height setting, this will be the speed your fan
runs at.

Fan Speed Max (%)

This is the fastest speed at which your fan will ever run. When your print speed is slowed
down due to Minimal Layer Time settings, your fan will run between minimum and maximum
speed. The maximum fan speed is reached when your printer speed is slowed by 50% or
greater.

Using Cura

Support

You dene how your support material is generated here. You must have a support type in the ‘Basic

Settings; in order for these support settings to have an effect.

Structure Type

You can choose between a ‘Grid’ or a ‘Line’ pattern for your support material. The grid will be
a checkerboard pattern in the X and Y direction. The line option will produce lines along the
Y-axis for support. The grid will provide stronger support than the line option, but will be
harder to remove.

Overhang Angle for Support (deg)

This will determine where support material is generated. In general you will be able to print
a model with 45 to 90 degree angles in relation to the Heated Print Bed without support. We
recommend leaving this setting at 45 degrees.

Fill Amount (%)

This will determine how dense your support material is printed, similar to Inll Percentage.

The higher percentage the better support, but it will be harder to remove the support

material and will use more lament.

Distance X/Y(mm)

This will determine how far away from your object in the X/Y plane that the support material
is being placed.

Distance Z (mm)

This will determine how far away your support material is from your object in the vertical
direction. A smaller number here is better for support, but makes it harder to remove.

Black Magic

This section allows you to transform your model into a hollow shell, a single layer thick

Spiralize the Outer Contour

This causes your Z-axis to be constantly moving upward as you are printing your single outer
wall shell. This results in no layer change lines, giving a much smoother surface. This setting is
typically only used for artistic objects as they will be fragile.

Only Follow Mesh Surface

This will cause your print to follow the outside of your model, building it completely hollow
with a single wall outer shell. The only difference between this and Spiralize, is that the Z-axis
moves regularly. That is, it prints a layer and then moves up to the next one.

Brim

Brim circles the base of the print while making contact, helping adhere the print to the Heated

Print Bed. This is only one layer thick, and can be easily removed post-print. This section denes

how the brim is formed when brim is activated in ‘Basic Settings’.

Brim Line Amount

This will determine the distance the brim will cover around the outside of your object. The
more brim used, the better your part will adhere to the plate.

Raft

Raft is a platform built underneath your object, designed to help adhesion and prevent warping.
It will lay down support material, and then a platform on top of the supports. Your model will be
built on top of this platform. The bottom surface of your printed object will not be as clean or as
even when using this option. Raft is typically not recommended.

Extra Margin (mm)

This determines the distance around the outside of your object that the raft is created. This
can be helpful for ensuring no warping occurs in the lower layers.

Line Spacing (mm)

This will determine the spacing between support lines for the raft. A small spacing makes
the support structures closer together improving strength of the raft, but uses more

lament.

Base Thickness (mm)

This denes how thick your raft will be.

Base Line Width (mm)

This will dene how wide your support material is for the raft. This setting will determine

how well the surface layers of the raft print.

Interface Thickness (mm)

This will determine how thick the surface layers of the raft are. The surface layers are the
platform that is built upon the supports.

Interface Line Width (mm)

This will determine how wide the top layers of the platform will be. In general, you can keep
this set to your nozzle size, as surface quality of the removable raft is not important.

Using Cura

Airgap

This will dene the distance between your raft and your print. A larger gap will make your

part easier to remove, but will make the bottom of your print look worse.

Surface Layers

This will determine the number of layers that create the ‘platform’ of your raft. If you have a
wide line spacing, you may want to increase this number to ensure a solid platform.

Fix Horrible

These are some of the more advanced and experimental options. They are designed to help repair
models with errors to make them suitable for 3D printing. However they may not always work.
Please be cautious when using these options as they can have unintended effects on your print
quality.

Combine Everything (Type-A)

This will attempt to x all external mesh errors, while keeping internal holes intact. This can
accidentally ll in intentional internal holes.

Combine Everything (Type-B)

This will ignore all internal holes of the model and only focus on the external holes. This is

helpful when only the outside nish of the model is important.

Keep Open Faces

This will ignore all manifold errors in the object. It can create issues generating the Gcode as
Cura does not know how to interpret the open holes. This option should only be used if you
are sure that the holes in the mesh are intended. In general, you should not use this option.

Extensive Stitching

This causes Cura to automatically add triangle mesh in an attempt to x manifold errors. This

algorithm will greatly increase Gcode generation time and may end up adding in
un-intended mesh. It is recommended that you repair your model through your CAD
program before attempting this option.

7.1 Replacing the Print Mat

The WANHAO 3D Printer includes 2 x Print Mats. Additional Print
Mats are available for purchase from id.aliexpress.com/store/120824

1. Remove the current Print Mat by slowly peeling from one corner

2. Using rubbing alcohol and a microber towel, carefully remove any

residual adhesive left on the Heated Print Bed

3. Peel the 3M backing from the new Print Mat

4. Gently place the new Print Mat onto the Heated Print Bed, making

sure to align with each edge. It is recommended to start at a corner
to ensure no bubbles become present

5. Use the Scraper to apply pressure on the new Print Mat, ensuring
strong adhesion. Keep the Scraper level as it can damage the Print
Mat

TIP: Warming the bed slightly may make removal easier. You can also use masking tape in lieu of
a Print Mat. Blue painters tape is recommended.

Servicing

7.3 Routine Component Check

Motor Connectors

Loose motor connections could cause a 3D print to fail. It’s a good habit to routinely check for any
damage to the connectors or the black cables.

Axis Lubrication

Regular lubrication of the X and Y Axis rods is important for the longevity
and smooth running of your printer. The rods can be lubricated with oil or
grease. We recommend using bearing grease, and to apply generously to
both the X Axis and Y Axis rods.

Nuts and Bolts

Loose nuts and bolts could affect the geometry of the 3D Printer. Check

that all nuts and bolts remain rmly tightened. If required, re-tighten using

the hex wrench.

7.4 Storing

Always store your 3D Printer in a cool, dry location that is free from dust.

Finishing

8.3 Sanding

Though Fused Filament Fabrication (FFF) is capable of producing high quality objects straight out

of the machine, the layer lines will be visible. Sanding will reduce these ‘step’ marks in the model.

1. Ensure that safety goggles and a mask are worn for protection

2. Starting with 100 grit sandpaper, carefully sand your 3D object using small, circular motions

NOTE: PLA is less resistant to high temperatures caused by sanding. Take your time sanding your

3D object to avoid damage.

3. Using the medium sanding sponge, sand difcult to reach areas of your 3D object

4. Gradually increase the sandpaper grid until the 3D print is smooth

TIP: Spraying a primer ller will also help to reduce the layer lines on the 3D Object. This can

then be sanded away and repeated, until the desired smoothness is achieved

8.5 Surface Coating

Finally, to make your models more presentable, follow these steps;

1. Ensure that safety goggles and a mask are worn for protection

2. Ensure that your 3D object is clean and free from dust

3. Spray your model using an acrylic based primer, following the directions of your primer

4. Allow appropriate time to dry before applying additional coats

5. Spray your model using an acrylic based paint of your colour. Allow appropriate time to dry

6. Spray your model using an acrylic based varnish, following the directions of your varnish.

Allow appropriate time to dry before applying additional coats.

NOTE: Different paint types are also compatible with PLA and ABS. Consult your local paint supplier
for the best compatibility for your intended purpose.

Congratulations! Your 3D object now looks like a professionally nished product!
