You have just purchased a new type of 3D printer using Direct UV-light Printing (DUP)
technology. This is a newly applied-for method of LCD image creation allow controlled UV
light get through the LCD screen which hardens liquid with the light from an UV light source.
This revolutionary system is a new way of printing that uses normal UV light as the energy
providing source to initiate the free radical polymerisation necessary to change the liquid

imagepac resin into your hardened object.

Congratulations

The principle behind your printer

There are two surprising advantages of this new DUP technology:
i) We can use high resolution low cost LCD screens that are widely available as monitors,
tablets, mobile phone and televisions providing phenomenal value for money, which we
pass directly onto you.

ii) The energy used by Duplicator 8 MARK I printers is again an order of magnitude lower
than used in comparable systems. This is good for your energy bills and the ecology, but
there is a huge performance advantage in that there is no unnecessary energy created. All
of the available photons strike photoinitiators and hand over their energy. In comparable
Digital Light Projector and laser systems there is a lot of excess energy which can lead to
over-cure.

Safety Information

Read the instructions carefully. Keep this document for future reference. Follow all warnings
and instructions marked on the product.
Observe the following guidelines when connecting and disconnecting power cord to the

Cleaning the machine

F

and your printed objects

These steps will reduce any resin spillage and keep your machine clean.

1. Move the platform up enough so the base of your object is clear of the vat.
Remove the hood on the print platform. Tilt the platform backwards in
order for the excess resin to drip back into the vat.

2. With absorbent paper under it, remove the platform completely and set it down
on a surface that will not be affected by resin. Place the hood back on immediately
to protect the resin in the vat from light.

3. Remove any excess polymer with paper rst. Place the platform to a washing-up

bowl and remove the objects by sliding the scraper in at their base. Wash off any
liquid polymer by alcohol.You can gently clean it with a soft brush or sponge,
taking care not to damage it, it will not achieve full hardness until after post
exposing in light. If you have an ultrasonic cleaner this will clean it without the
possibility of damaging it.

4. Check it is thoroughly clean then place it in a container for 10-20 minutes in an area
with bright sunlight. You can use light from a UV lamp. When it has been
completely post exposed, it will be stronger and have a dry surface. You will notice
that it darkens in colour as it is exposed to light. Dry it and check that it is dry, if
not repeat.

5. Clean the build platform with industrial alcohol , chip off any cured resin and
dry it before inserting it back into the printer.

6. You should empty the vat and clean it every time in case you have any solid
pieces on the bottom, as these would prevent the platform from homing
correctly. Loosen the Z brackets and remove the vat from the printer, pour the resin

back into the bottle through a strainer. Place the vat on a at surface and wipe the

base of the vat with absorbent paper. Make sure it is clean and not damaged. If it

is not at, clean and tight like a drum, remove the lm and replace it with a new piece.

7. If you have a leak on the screen it is easy to remove the hardened resin
without damaging the screen by shipping it off with a blunt non-serrated knife.

From left to right, the other tools are:

* The ‘Put on the plate’ button will position the bottom of the model to rest on
the bottom of the build platform.

* The ‘Center’ button will center the model at (0,0,0).

Auto-Arrange will automatically lay out all models to t on the build platform.
Any model that does not t within the build platform will be moved outside the

build area.

8. Working with Model Support tools

Using Supports

Supports are sometime required to properly attach a model to the build space.
Because of the nature of DPP the lower layers must be supported by the supports

unless it has a wide surface in the rst layers.

Adding a single Support

A single support can be generated by clicking the manual support button/

Angled Supports

Supports can be angled inwards towards the objects they support. This can often resolve
clearance issues with vertical supports. You can turn a vertical support into an angled
support by selecting it, and holding the ‘Ctrl’ key and clicking on the model you want to
support.

11.Save a Scene

Click to save the current object as a .STL le. The .STL format allows

you to prepare a scene to be printed repeatedly in the future, together with supports
and positioning.After models have been loaded and manipulated on the build
platform, the entire scene can be saved as an STL model for later use. These scene

les can be used to create a scene with supports, slice the scene, and later load to

print your scene without the need for re-slicing.

From this screen we will be able to control the motors of the printer , which means
displacing the build base over the Z axis, as well as controlling the LCD.In this section
of the Control screen we have the buttons that will allow us to move the Z position
of the build base. Using the value indicated as z Rate (at the bottom) you can change
the speed of progress measured in millimeters / minute.

13.Others functions

Wall Thickness: This eld is to set the thickness of each slice in mm. The default is

.05mm (20 slices per mm)

Bottom Layer Count: This species the number of ‘bottom layers’ that receive the

longer exposure time.
Exposure Time per Layer: This time value specifies how long the projector will
display an image slice on a per-layer basis.
Bottom Layer exposure time: In order to ensure the model is properly adhered to

the bottom of a vat, a longer exposure time can be used for a specied number of

bottom layers.
Light -off Delay: This setting can delay the UV led lighting before starting to print.
Bottom Light -off Delay This setting can delay the bottom lighting before starting to
print.
Lifting Speed:When a layer is printed on a bottom up machine, a large amount of
force may be required to separate the slide from the vat. This speed indicates how
fast to perform the lift, a slower speed may be required to help vat separation.
Retract speed:After the lift occurs, this speed indicates how fast the z axis should
travel back to the initial start position.
