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 WANHAO 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. Websits 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 'Slice' converts a 3D Design (usually an .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 the program Cura as it uses a simple interface and includes a large amount of

support material.

Setup WANHAO 3D Printer

It's important to check your printer before every print.We've included
some steps on page 21 in section 4.2 Good 3D Printing Practices

for you to quickly refer to each time.

3D Printing Process

Now that you've loaded a GCODE file onto the printer,it will
commence heating up the Extruder, then start printing. While
printing, the nozzle will move along the X and Y acis 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 affect printing time:

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.

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, like poor adhesion and

warping, will occur in the  rst layer. If problems occur, stop the 3D Printer in the menu or

power off the printer

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 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 Beds/ mats
may affect adhesion for future prints

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

21

PRINTING AND REMOVING MODELS

4.3 Removing 3D objects from the bed

Once the I3 Mini has completed printing your 3D printed object follow these steps to
remove it from the print bed.

1. Once the print is completed,wait for the extruder to cool and then turn off your 3D printer

2. Using the supplied, carefull'wedge'under one of the edges of the 3D object.Take

care to keep the scraper at with the bed to preven damaging the print mat

3. As one edge begins to lift,gently maneuver the scraper forward to continue to'wedge
between the 3D object and print bed

4. Once the 3D object has fully separated from the print bed,it is safe to remove

NOTE:
* Always take care when using the scraper.Never use excessive force scrape towards your hand.
Scrape away from the body and keep hands clear to prevent injury
* Always keep the scrape as level as possible.Scrape can damage the print mat if not used

corretly
* 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 bule masking tape(designed to not leave behind residue) on the print bed.Be
sure to remove and replace after each print
* Check if the printing mat is damaged and replace if needed
* Replacement mats can be purchased at https://www.wanhao3dprinter.com

4.4 Removing Filament

Follow these steps to remove alment
NOTE: You do not have to remove lament after each print,however

if you do not intend to print for long periods of time we recommend

removing and storing lament in a resealable air tight bag

1. Turn on the 3D printer with the power switch located at the back
of the printer

2. Push the dial button to access the main menu and navigate to

Quick setting Chanege lament Remove lament.

The extruder will automatically raise and preheat;always wait
until it has fully preheater

3. After the extruder has preheated,hold the lament clamp on the
top of the tower and push the lament so a small amount begins

to extrude

4. Once lament is extruding from the nozzle,while holding the lament clamp,quick pull the
lament out of the extruder and tube

5. Store the lament in a resealable bag to protect it from moisture

SETUP

4.8 Storage

PLA 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 stroing PLA or other material 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

4.9 Creating and Printing your own Models

4.9.1 Saving les to MicroSD Card

* Format new MicroSD Cards up to 32GB to FAT32

* Save les only in the root directory on the MicorSD Card.The I3 Mini will not read les in

folders.

* Ensure your models are saved as GCODE les.STL and other 3D le formats should be

converted or 'sliced' into GCODE before loading them on the MicroSD Card. See the section

Creating a GCODE le using Cura for information on creating GCDOE les

4.9.2 Creating a GCODE le using Cura

A GCODE le provides the essential temperature settings and movement information for your
WANHAO I3 Mini. A number of 'Slicer' software programs exist which convert a 3D model le

into a series of 3D printable layers. Cura is free open source slicer software relesed on the
AGPLv3 license.It is available on MacOS X and windows.

4.9.3 Installing Cura

1. Install the le located on your included MicroSD Card or download Cura from

www.wanhao3dprinter.com

2. Select a destination folder for the install,then press'Next'

3. Select the components to install,then press 'Install'

4. Once complete,press 'Finish'

5. Refer to your computer manual of further instructions on the above steps if required

2. Remove most of the support material by hand, taking care not to

damage the 3D object

3. Using the long-nose pliers, carefully grasp some of the remaining
material, then twist to remove. Repeat until no more material can be
removed.

4. Using the wire cutters, cut away any excess  lament.

6.1.3 Sanding

Though fused  lament 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 of protection

2. Starting with 100 grit sandpaper,carefull 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 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
