2. LET’S GET STARTED
2.1 INTENDED USE
LumiForge is a device created to produce tridimensional prints of parts in the limit described in the
following “Tech specs” paragraph. Any further use is forbidden.
LumiForge uses a DLP projector that cures the photosensitive resin contained in the vat. The original
solid is the result of a predefined number of parallel slices, depending on the resolution chosen by
the user. Each slice becomes an image which is projected into the vat by the DLP projector. The resin
will start the curing process required to form a layer as soon as the light hits the resin. The process
goes on layer by layer until an object is successfully created!
WARNING: This appliance can be used only by kids aged from 16 years old or above.

-To install the projector inside the 3D printer, hold it vertically with the lamp facing down
(img. 3.a).
-Match the plate mounted on the projector to the black plate (n. 10) inside the printer (img.
3.b)
-Screw the two knobs provided into the two holes indicated on the plate external side (img.
3.c and img. 3.d)
-Now connect VGA and Power Supply cable inside the printer to the corresponding socket on
the projector (img. 3.f).
ATTENTION: We suggest inserting the VGA cable between the two sustain bar (n.17) to avoid it to
interfere with projector movement (img.3.f).
Img.3 install the projector inside the 3D printer
-Follow projector manual to turn the grey zoom ring above the projector outwards so to set
the closest zoom. Always make sure that zoom ring is in this position.
-Install the servo-shutter provided (n.15) on the blue servo (n.16) located below the projector
(n. 8) (img.4)
-After installation It is possible to open or close the servo-shutter manually, pressing together
the last two keys on the right on Lumiforge front panel (n.7) (img.5).
-If, when on the closing position, the shutter does not cover all the light flux, remove it and
install it again with a rotation.

Img.4 Install the servo-shutter
IMPORTANT: the servo-shutter is meant to protect the resin from unwilling light from the
projector and we advise to keep it closed. During the printing process, it will open and close before
and after every layer projection, unless “stop servo” is flagged on LumiCreator.
In case you are keeping the projector so close to the projector that the servo-shutter is banging
on the resin vat, you can remove it and flag “stop servo” to stop the action. However, be aware
that removing the servo-shutter, the resin will not be protected in case the projector will start
emitting strong light.
Img.5 Open or close the servo-shutter manually
4.4 Installing printing carriage and vat on LumiForge
-Insert the carriage (n. 12)in the housing of the movable base (n. 13) (img.6)

-Connect the other end of both USB and VGA cable to the corresponding ports of your
computer (img.9).
-In case your computer does not have a VGA port, you can use an adapter.
Img.9 Connecting USB and VGA cable to the computer.
IMPORTANT: LumiForge will only work if, upon connecting the projector, your computer screen
setting is set on extended screen.
-Enter screen settings on your computer to project on a second screen. Choose screen
extension.
4.6 Switching LumiForge on
-Connect the corresponding end of the power supply cable (n.28) provided in the projector
box to the black socket (n.22) at LumiForge back and the plug into the electric socket
(img.10).

Img.10 Connect power supply cable
-Switch the red switcher (n.23) on
-The printer is NOW on.
-Once the printer is on and connected with the computer with the USB cable, the frontal
panel (n.7) screens will light up and fans (n.4) will start to move.
IMPORTANT: Fans are very important to keep the temperature inside the printing area cool and
save projector life. LumiForge fans are provided with a set of filters to protect the printer inside
from dust. Check filters regularly to make sure they are always clean. To clean the filters, blow
them with compressed air o similar.
-Launch LumiCreator software.
-Once the software is launched, the carriage (n.12) and the projector movable (n.9 and 10)
bases move up at the starting point.
ATTENTION: when carriage and projector start to move up, be careful that internal black cable
spiral holder and the VGA cable do not interfere with their movements. If it does, push them
away. We suggest to insert the VGA cable between the two sustain bar (n.18) to avoid the cable
to interfere with the movement (img.11).
Img.11 Correctly position of VGA cable.
ATTENTION: After moving up, both carriage and projector should stop and sensors (n.5) should
light up in red (img.12).

LUMIFORGE USER MANUAL

Img.12 sensors lighting up.
If sensors do not light up and you keep listening a sound of striving motor, this mean that:
The black spiral cable holder is interfering with the projector movement, in this case just
move the cable holder away.
Something else is in the way and is not letting the sensors to stop the movement, in this
case remove the obstacle
Sensors are faulty, in this case switch the printer immediately off and ask for assistance.
ATTENTION: CHECK THE SENSORS (N.5) FLAP REGULARLY. SENSORS SHOULD LIGHT UP WHEN
FLAP IS MOVED UP! (img. 13)
Img.13 sensors flap.
IMPORTANT: If the starting movement does not happen, please proceed to calibration on the
Software second screen. On the right menu, click on “scan for printer”. If the printer is not
detected, please check if the USB cable is correctly plugged to both the printer and the computer.
Try to plug and unplug and press “scan for printer” after each time until printer is detected.
-Now turn the Projector on (either with the power button on the device or through the
remote controller if supplied).
ATTENTION: Many projectors will flash light on start-up, or, if you switch your projector on
without having launched LumiCreator software, it will project a powerful light, which may cure
your resin unwillingly. Therefore, if you have already placed the resin vat below the projector, be
sure that the servo-shutter (n.15) is covering the projector lamp.
It is possible to open and close the servo-shutter, pressing together the last two keys on the right
(C+D) on Lumiforge front panel (n.7) (img.5).

4.7 Preparing the resin vat
-Pour the resin from the bottle to the provided resin vat (n.6)
WARNING: always wear protective gloves and goggles when using the resin. They may cause skin,
eye and respiratory system irritation, and skin sensitization/allergic reaction by skin contact.
ATTENTION: As photosensitive pigments tend to deposit after a while, stir the resin well before
each print, in order to avoid colour spoiling.
IMPORTANT: the level of the resin MUST be at least 1 cm higher than the height of object you are
about to print
-Uninstall the printing carriage (n.12) from the movable base (n.13), unscrewing the two
knobs (n. 14)
-Immerse the carriage inside the vat (n.6) full of resin ( img 14.a )
-Place the vat with the resin and the carriage on the printer internal surface (img 14.b)
-Now install the carriage as mentioned in point 4.4.
Img.14 How to install the resin vat correctly.
IMPORTANT: Never place the resin vat when the carriage is installed by tilting the vat (img. 14.c).
Resin might pour out.
ATTENTION: In case resin is unwillingly poured on the printer internal surface, switch the printer
immediately off, absorb the resin with a paper towel and clean the surface with alcohol to remove
resin traces.
Before switching the printing on again, make sure that the liquid has been totally removed and it
has not infiltrated inside the printer bottom part where the electronic board is placed.
Always contact our service support and never open the printer bottom area, it will invalidate the
warranty.
