Congratulations
You have just purchased a new type of 3D printer
using Daylight Polymer Printing (DPP) technology.
This is a patent applied-for method of image crea-
tion that hardens liquid with the light from an LCD
screen. This revolutionary system is a new way of
printing that uses normal daylight as the energy
providing source to initiate the free radical polyme-
risation necessary to change the liquid imagepac
resin into your hardened object.
The principle behind your printer
There are two surprising advantages of this new
DPP technology:
i) We can use high resolution low cost LCD
screens that are widely available as monitors,
tablets, mobile phones and televisions provi-
ding phenomenal value for money, which we
pass directly on to you. This is why our machi-
nes are a fraction of the price of machines of
similar performance.
ii) The energy used by Liquid Crystal printers is
an order of magnitude lower than used in sys-
tems. This is good for your energy bills and the
ecology, but there is a huge performance ad-
vantage in that there is no unnecessary energy
created. All of the available photons strike pho-
toinitiators and hand over their energy. In Digi-
tal Light Projector and laser systems there is
a lot of excess energy which can lead to over-
cure and lead to excess attraction between the
imaging source and object at the build layer.

USEFUL
ADVICE
Please ensure any minors are supervised at all
times.
Use in a well-ventilated room.
Keep the printer out of the reach of small chil-
dren.
The resin is an irritant to skin and eyes. Always
wear gloves when coming into contact with the
liquid resin. We have developed and used the re-
sins extensively for many years and have a lot of
experience with them. Resins meet health and sa-
fety requirements but in exceptional circumstan-
ces people can be sensitive to the resin and deve-
lop a skin irritation or rash. Avoid this possibility by
always wearing gloves.
The printer should be operated on a stable and
level surface, preferably away from direct ambient
light and with sufficient space to be able to open
doors.
Please note that the latest instructions will always

3. PREPARE
LIQUID CRYSTAL
FOR PRINTING
A. STARTING A PRINTER
FROM A BROWSER.
Now you have your printer installed and
configured.
There are 3 ways to start a print:
A. Start a print from a browser (computer, tablet,
phone) using Printflow 3D.
B. Start a pre-sliced and uploaded print from
the LCHR touchscreen.
C. Start a print after uploading a file from a USB
stick.
Please read these software instructions to help
you start printing.
1. Make sure your printer is turned on and
connected to a network. If the LED at the
front button is illuminated then the printing
screen is turned on.
2. Download the desktop software called
“Printflow3D_opener” for your operating
system from www.photocentric3d.com/
printflow.
3. Move the Printflow3D_opener.exe onto your
desktop, double click and start the software.

4. When your printer has been found succesfully, it should open up the following window.
5. Click “Browse” and upload the printable in .stl file format; your window should look like
this. Apply any desired modifications as described later in this document.
6. Once the print is ready, select the resin profile from the “Settings tab” / “Resin configuration”.
7. Go to the “Control” page.

8. Your platform and vat should now be assembled.
Tighten the central knob to lock the platform.
9. Ensure the two side knobs are completely
loose. Pressing ‘Home’ with them locked could
damage the screen.
IMPORTANT: If these knobs are not completely
loose you could crush the bottom screen when
lowering it with the home function.
10. Place the hood back onto the printer (for safety
reasons, printer will not respond mechanically
until it has the hood on).
11. In the controls section of PrintFlow 3D, click the blue button with a home Icon. The platform will
move down to rest on the screen (level 0 in Z axis) and stop. Remove the hood.
With the vat empty and wearing gloves, press down in the middle of the glass platform to ensure
the platform is in contact with the vat film across its entire area. You will see the screen go white in
all four corners. Then with the other hand tighten one of the side bolts and then tighten the other. It
is now locked in the home position. You can now fill the vat with resin.
NOTE: Prints consume around as much resin as
the volume of the object. If you have an object
that is 100 cm3 then it will use 110g of resin. For
most prints, filling the vat to 1/3 full is more than
enough. Make sure that the bottom of the vat is
always covered with resin. Place the hood back
on the printer.
NOTE: You can check the screen
is working by pressing the “Show
calibration” button located in the
“Control” tab and a grid will ap-
pear.
NOTE: Don’t remove the hood during
the operation or the print will stop.

12. Go back to the tab “Home”, press “Slice” and then finally, press “Print”. This will cause the software
to slice the object and begin printing afterwards. Please note that during slicing your browser page
should remain open.
1. On the homepage, click on “Resin settings”.
To start a print from a touchscreen you can either use print files already loaded on the printer or you can
upload presliced .zip files from a USB stick. To upload files from the USB stick, simply insert the USB in
the front of the printer, go to the homepage and wait. After a few seconds, press the Print button and all
of the .zip files should be uploaded to the printables and be available to print.

These steps will minimise any resin spillage and
keep your machine clean.
1. After printing press the ‘+50’ button and the
platform will rise to above the level of the vat.
Remove the hood and loosen the two side
bolts, tilt the platform slightly to allow the resin
to drip off.
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 first.
Place the platform in a washing-up bowl and
remove the objects by sliding the scraper in
at their base. Wash off any liquid polymer by
running hot water over it. 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. An ultrasonic
cleaner is useful for cleaning delicate objects.
4. When fully clean leave it in light to harden. The
part will only have around 1/4 of its final strength
before post-exposure and strength increases
slowly in light. Full strength is achieved with 30
mins in a UV unit or a strong daylight source,
or 60 mins under a normal 60W table lamp at a
distance of about 5cm. In a window it depends
upon sunlight strength but may take up to 12
hours.
5. Clean the build platform with hot water and
soap, chip off any cured resin and dry it well
before inserting it back into the printer.
6. You should empty the vat and clean it after
every print, in case you have any solid pieces
on the bottom, as these would prevent the
platform from homing correctly. Loosen the
thumb screws and remove the vat from the
printer; pour the resin back into the bottle
through a strainer.
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 credit card
or plastic scraper.

3. Place the “Vat Base Flange D flat on a table”
with the brass inserts pointing down.
4. Check the new vat film isn’t pierced or dented
and lay it on top of the “Vat Base Flange D”.
5. Place the “Vat Retaining Flange C” on top of the
film, aligning the holes with the corresponding
ones on the “Base Flange D”.
6. Tighten the 8 x M3 8mm bolts as shown.

7. Place the main vat tray over the film and gently
press down. Screw the remaining 12 x M3
12mm screws in and the film will tighten.
Note: Refrain from fully tightening each bolt
individually. This will cause the Main Vat to tension
at an angle. Aim to half tighten the bolts and fully
tighten once all the bolts are secured.
8. The vat should now be tensioned. Trim excess edges.
