INTRODUCTION
This printer uses an LCD screen to mask a cross section of your model, one layer at a time,
using a 405nm UV light array to cure resin held in a vat. The LCD screen is positioned
beneath a vat of resin, with a transparent film separating the resin and screen. Between
layers, the printer will lift (or "Raise") the print and return it one layer higher than
previously. This lifting action allows uncured resin to flow under the print and back into the
vat. This process is repeated layer by layer to shape the object.
Because of how it this style of printing works:
Finer levels of detail are able to be printed than with FFF or filament printers. This
printer is equipped with a 2K screen to print at higher resolutions.
The height of the object is the main determinant on how long it will take to print
the object. Additional models across the build platform will not increase time, as
long as the height does not increase.
Supports should be included in any areas that would be "Islands", or areas that
would not be touching the already printed parts of the model. They should also be
used for heavy pieces that risk falling off of the build plate.
Keeping the build platform, resin vat, and transparent film clean of debris and cured
resin is a must for successful printing.
Cleaning the print and final curing are necessary post processing steps. Natural
sunlight produces all the UV light necessary to cure the final print. Exposure to
sunlight on a well-lit window sill for half an hour or longer will be sufficient for the
final curing process.

USEFUL TOOLS
There are a few tools that will make life easier when working with a resin printer. Some of
these are more important than others, but this list covers what a good workstation should
contain in ideal conditions.
Disposable Gloves: Always wear gloves when working with uncured resin. Nitrile gloves
are what we use in our lab. Neoprene gloves are also useable. Do not use latex
gloves. If resin gets on your skin, immediately wash it off with soap and warm
water.
Safety Glasses/Goggles: Always wear safety glasses/goggles when working with
uncured resin. If resin gets in your eye(s), immediately flush with cold, clean water,
then consult a doctor.
Metal Scraper: A putty knife or similar instrument can help remove prints from the build
plate when they stick a little too well.
Isopropyl Alcohol: Isopropyl alcohol is used for cleaning the finished print and any tools
that have come in contact with resin.
Spare Containers: Spare containers are always useful with liquid resin. They can be used
to store used resin, which you will recycle, to wash your finished print (be sure that
the container can be used with isopropyl alcohol), or to hold tools after they have
come in contact with the resin.
Plastic Scraper: A plastic scraper, such as an expired credit card, is used in the event
that a print fails and sticks to the FEP liner at the bottom of the resin vat. Refer to
the
CLEANING THE RESIN VAT
Paper Towels: Use paper towels to clean the workstation and prevent dripping on your
workstation.
Aluminum Foil, Plastic Wrap, or Plastic Liner: Use any of these products to protect your
workstation from resin drips.
Storage: You need a place to store everything to make the workflow easier.

AUTO CALIBRATION
Whenever the printer is sent to the Home position or whenever a print is started, the
printer will automatically calibrate the Printing Platform. This requires the Resin Vat to be
free of cured resin particles or print failures can occur.
ABOUT RESINS
Resin Storage
Resins should be kept in a dark and ventilated place. The storage location should be kept in
the +68 ~ +86°F (+20 ~ +30°C) temperature range. Lower temperatures can extend the
shelf life. The official shelf life is one year.
Resin Operation
Wear gloves when working with resin to prevent direct skin exposure. If resin does get on
your skin, wash the exposed area immediately with soap and warm water.
Cured resin is safe to handle without gloves. Printed models should not be used for food
applications.
Safety and Resin
There are many types of resins and resin manufacturers. This section contains general
safety guidelines for handling resin.
Wear gloves when working with uncured resin.
Wear safety glass/goggles when working with resin.
Do not eat or drink resin.
Refer to the Material Safety Data Sheet (MSDS).
19
Transferring Resin to Storage
When you use resin, small portions can be unintentionally cured. For this reason, it is
recommended to not mix used resin and unused resin. The used resin can be filtered using
a fine mesh to remove any cured bits. For best results, store the resin in a black container
with a lid. The container should be stored in a dark, ventilated place to prevent curing
during storage.
Discarding Resin
Before discarding resin, it should be fully cured. The easiest way to cure the resin is to pour
it into a clear, disposable cup, then placing the cup in direct sunlight until the resin is fully
cured.
PRINTING TIPS
Check the Resin Vat and Printing Platform before printing to ensure they are clean.
After removing the model, cover the lid to prevent the remaining resin curing.
After printing is finished, store the remaining resin in another container or leave it in
the Resin Vat. The shelf life will be significantly shorter for used resin. Adding fresh
resin can increase the shelf life.

Click to add bottom supports.
Click to automatically add necessary supports to the model.
You can control the size and shape of supports using the Support
Shape portion of the screen. Note that the top of the support must
not be less than 0.25mm and the base must not be less than 0.6mm.
Note that if you model using PRO/E or CREO, the FRONT face is the
bottom of the model instead of the TOP.
22
The imported model may differ in size and location from the print
area. You can adjust the model using the controls on the Property
Bar on the right side of the screen.
The Move (mm) button allows you to easily and quickly locate the
model file. Clicking the button reveals the following options:
Click to "fit the base". This should be done prior to
each cut.
Click to move the XYZ axis absolute to the middle.
Click to move the model to the middle of the build platform.
Click the Configure button, then click Configure Slicing Profile to display the following
screen.
23
Special note should be made of the following options:
Enable Slice Outlines: This is the feather value option. The larger the value, the
smoother the printed model will be. This can reduce the model pixel pattern. The
general value of 3 or more can effectively alleviate.
Slice Thickness (mm): The setting range is 0.02 - 0.1 mm, with a default value of
0.05mm. The smaller the thickness is, the higher the accuracy and the more time it
takes to print. Exposure time can be reduced if the layer thickness is smaller.
Exposure Time (ms): This value can be set according to the actual situation. The
default is 15 seconds. Smaller and simpler models can reach up to 3 seconds. If the
details of the print cannot be shown during printing, the single exposure time
should be increased. For models with holes, a shorter curing time is better. For
models with smaller columns, the longer the curing time, the better the effect.
Bottom Exposure (ms): The default exposure time for the bottom layers is 60
seconds. When printing smaller and simpler models, the exposure time can be as
short as 5 seconds. Increase the exposure time if the model won't stick to the build
platform. The longer the exposure time is, the more tightly the model will stick to
the build platform.
Z-axis Lift Distance (mm): This value can be set according to the model size. If the
area is too large but the lifting height is low, the resin cannot be returned to the
middle of the model, resulting in a bubble in the middle, a defect, or print failure.
Z-axis Lift Speed (mm/m): The default value is 100mm/m. It is recommended to use
a value between 50-150 mm/m.
Z-axis Retraction Speed (mm/m): The default value is 100mm/m. It is recommended
to use a value between 100-150 mm/m.
Note: Click Apply Changes to save your custom settings.
24
Click the Configure button, then click Configure Machine to display the following screen.
If the print size is different from the actual size, you can change the display size. Correct
the print size by adjusting the XY values in the Build Size (mm) section. Click Apply
Changes to save your settings.
SLICING WITH CREATION WORKSHOP
Perform the following steps to slice a model using Creation Workshop.
1. Run the Creation Workshop software program on the included microSD™ card.
2. Click the button to load a model file (STL or OBJ).
3. Click the button to save the loaded model file in Creation Workshop format.
4. Click the button to slice the loaded model file.
25
5. Copy the resulting CWS file to the microSD™ card or send it over the network to
the printer.
MODEL CLEANING
Perform the following steps to clean your finished print/model.
1. Once the print has completed, twist to remove the build platform, then use a metal
putty knife or spatula to remove the print from the platform.
2. Place the model in a container filled with isopropyl alcohol. Cover the container,
then shake it vigorously for about 30-60 seconds.
Note that the cleaning time should not be more than 5 minutes. If it is cleaned for too long,
the details on the model will soften and the model surface will begin to whiten. The
cleaning time should be shorter if the finished print has a lot of small/fine details.
3. Once cleaning is finished, place the model in a sunny location or under a UV light.
The curing time will depend on the type of resin used.
CLEANING THE RESIN VAT
It is not uncommon for cured resin to stick to the FEP lining in the bottom of the resin vat.
Perform the following steps while wearing gloves to clean this type of obstruction.
1. Use the included hex wrench to remove the protruding screw on the left side and
the protruding screw on the right side of the resin vat.
2. Pour the resin from the vat into a separate container. Do not pour it back into the
original resin bottle. A mesh strainer can help remove small pieces of free floating,
cured resin.
3. Using a plastic spatula, an expired bank/credit card, or other plastic tool that does
not have sharp edges, gently peel the resin from the FEP lining. The FEP lining is
extremely thin and can be torn or punctured if approached too aggressively or with
a sharp tool. Remove any remaining pieces of cured resin.
26
4. Use isopropyl alcohol and paper towels, clean the vat of any remaining resin. The
FEP liner should be as clean as possible.
5. Reinstall the vat into the printer.
TROUBLESHOOTING
1. If the print finishes and there is nothing on the build platform, there can be three
potential reasons:
The first layers did not cure enough and the print has fallen off the Printing
Platform. Increase the base cure time. For Monoprice resins, the base cure time
should be 60 seconds. Other resins may require different amounts of time.
The Printing Platform did not level correctly. Verify that there are no small
particles from previous prints in the resin vat, as this will disrupt the leveling
process. Keeping the resin vat clear of small pieces of cured resin in an absolute
necessity.
Run the "Clear" function on the Control Menu to verify that the LCD screen is
turning on and off.
2. If the first layers are present, but the rest of the model is missing, there can be two
reasons:
The cure time for the resin in not long enough. The model likely fell into the vat
and it will be necessary to remove it before attempting to print again. The
default exposure time for Monoprice resins is 8 seconds for layers other than the
first three layers.
The model has insufficient supports. Add additional supports to compensate for
the weight of the model during printing.
