across the heater into the resin tank to heat the resin.
•
Resin - Resin flows from the cartridge into the tank when the cartridge dispense arm squeezes
the valve open. The Form 3 regulates the volume of resin in the tank through a sensor called
the LevelSense board, which is located behind the resin tank. The printer begins to fill the
resin tank once a print starts and maintains the level of resin in the tank during the print.
Printing begins automatically when LevelSense detects the proper amount of resin.
5.2.5 Start or Stop a Print
To start a print, select the job on the touchscreen, and follow the prompts.
To stop a print in progress, select pause, then abort the print.
CAUTION
5.3 Finishing
Moving parts. Do not open the printer cover until the touchscreen indicates the print
is complete.
Part finishing includes all steps after printing. Follow these steps to bring a 3D model from a
digital file to a functional, printed part:
1. Print: Prepare the FORM file in PreForm, upload and start the print, and then monitor the
print progress on Dashboard.
2.
Wash: Use Form Wash or the Finish Kit to rinse the remaining liquid resin from printed
parts’ surfaces.
3. Dry: Allow at least 30 minutes for isopropyl alcohol (IPA) to fully evaporate after washing.
20
IPA is flammable. Keep containers closed, and keep out of the reach of children.
DANGER
4. Post-Cure: Use Form Cure to expose printed parts to light and heat to stabilize the parts
for performance.
5.
Post-Process: Remove supports, then use sanding, priming, or painting to improve
presentation, or use other equipment to create molds from printed parts.
5.4 Managing the Printer
5.4.1 Connect to the Form 3 with Dashboard
Dashboard (formlabs.com/dashboard) allows individuals and teams to remotely monitor
Form 3 printers, track material usage, and explore past and future Formlabs purchases.
Register the Form 3 to Dashboard through the touchscreen on the printer. Once the Form
3 is registered to Dashboard and Dashboard logging is enabled on the printer, the Form 3
will send data to Dashboard as long as the printer’s Wi-Fi or Ethernet connections are able
to access the internet.
5.4.2 Change Resin Types Between Prints
When changing resin types, always change both the tank and the cartridge. Remove the
cartridge before removing the tank to prevent the cartridge valve from dripping resin into
the printer.
See 6.5.2 Maintain the Resin Tank and 6.5.4 Remove and Replace the Cartridge.
5.4.3 Manage or Delete Uploaded Prints
• To start an uploaded file:
Confirm the resin tank and cartridge match the file’s resin type and version.
°
Tap the file name from the queue.
°
• To delete a print from the queue:
Tap the file name from the queue.
°
Tap delete.
°
5.4.4 Fine Tune the Form 3
Adjust Fine Tuning settings to correct any consistent, small-scale dimensional errors or to
mitigate model adherence issues.
The Z Fine Tuning setting changes the “Z Oset” value to adjust the distance between the
build platform and the bottom of the resin tank.
The X/Y Fine Tuning option adjusts the scaling factor in the printer’s X and Y axes.
5.4.5 Check and Maintain the Resin Temperature
The Form 3 heats resin to a set temperature before starting a print. View the print chamber’s
current temperature on the touchscreen.
The print chamber is heated by hot air blown out of the tower behind the resin tank. The warm
air in the print chamber heats the resin, and the air temperature is sensed by a thermal sensor
at the air intake. The Form 3 automatically pre-heats and maintains a consistent print chamber
temperature before and between print jobs.
5.4.6 Power Off the Form 3
Turn o the Form 3 completely when moving or storing the printer and to conserve power. To
turn o the Form 3 completely, disconnect the power cord from thepower source.

6.2 Inspection Tasks Between Prints
6.2.1 Inspect the Bite Valve
Thebite valveis located on the underside of the resin cartridge. This flexible seal regulates resin
dispensing. Resin flows out of the opening in the center of the bite valve when thecartridge
dispense armsqueezes the valve open.
When switching to a dierent resin cartridge, inspect the bite valve for any cured resin or damage.
6.2.2 Inspect the Resin Tank Interior
See 6.5.2 Maintain the Resin Tank.
6.3 Monthly Inspection and Maintenance Tasks
6.3.1 Protect the ID Chips on the Resin Tank and Resin Cartridge
ID (identification) chips on resin tanks and resin cartridges detect, track, and match the resin
type in the tank with the proper resin cartridge. The ID chip is on the underside of each tank
frame and on the bottom of the cartridge near thebite valve.
Protect the ID chips, the tank carrier, the tank spring fingers, and the cartridge spring fingers from
resin contamination or damage. Cured resin or contamination prevents the printer from properly
identifying a cartridge or resin tank during insertion or use. Avoid exposing the cartridge ID chip,
the resin tank ID chip, the tank carrier, and the tank spring fingers to liquid resin.
6.3.2 Clean the ID Chips or Spring Fingers
To remove resin from the ID chip or spring fingers:
1. Apply a small amount of clean IPA to the tip of a cotton swab.
2. Rub the tip of the cotton swab onto the silver pads on the ID chip or onto and around the
spring fingers. The cured resin or contamination dissolves.

8. Disposal
8.1 Guidance for Recycling and Disposal
CAUTION
8.1.1
8.1.2 Disposal of IPA and solvents
Refer to the Safety Data Sheet (SDS) and local authorities for guidance on disposing of IPA.
Disposal of resin
Liquid resin (whether pure liquid, dissolved in alcohol, or partially cured) may be classified as
hazardous waste and shall be disposed of with care.
Disposing of empty resin containers:
In the United States, empty resin containers are considered “RCRA empty” by EPA standards
and can be thrown in the garbage as regular waste.
Optional - Triple rinse the cartridge with fresh IPA to empty the resin cartridge of traces of excess resin.
Add the resulting dirty IPA to your solvent waste stream in accordance with governmental regulations.
To dispose of a resin tank:
1. Remove the resin tank.
2. Transfer or dispose of the remaining resin.
3. Pour the resin from the old tank to the new tank or another container. If there is debris or
cured parts in the resin, filter the resin before transferring it to a new tank.
a. Pouring resin back into the original cartridge may risk contaminating the cartridge with
cured resin pieces or debris, which can cause print failures.
4. Use a paper towel to wipe any remaining resin o the old tank.
5. Place the old tank in sunlight (a window sill is fine) or UV light to cure excess resin, and
dispose of properly once cured.
Disposing of liquid resin:
To dispose of pure resin (resin that has not been cured or dissolved in alcohol), add this waste
to your chemical disposal stream.
If you do not have a chemical disposal stream:
1. Pour a small amount of resin into a labeled, resin-compatible container.
2. Leave the container outside, exposed to sunlight to cure for 1-10 days. Expose resin to 405
nm light and heat for the most eective curing. The liquid resin cures to solid material when
exposed to light and heat.
3. Dispose of the fully-cured resin and container in the trash.
Disposing of cured resin or cleaned parts:
Discard cleaned parts and cured (hardened) resin with household items as trash. Cleaned
parts and cured resin cannot be recycled.
Safe and appropriate disposal methods of used IPA vary by location.
To safely dispose of dirty IPA:
1.
Consult the safety data sheet (SDS) from the IPA supplier as the primary source of information.
2.
Research your local government’s approved methods of disposal. This will most likely
involve hiring a waste disposal service or, for smaller amounts, checking with your city’s
disposal service to see if they have any suggestions for removal.
32
Inform your waste disposal service that your bottle contains IPA with small amounts of
3.
methacrylated monomers and oligomers (unpolymerized plastic resin) and trace amounts
of photoinitiator. Have a copy of the resin SDS on hand in case the attendant needs
more information.
For large volumes of IPA, consider using a solvent recycling system, which oers a costeective and more environmentally responsible alternative to paying for waste solvent disposal
services. Solvent recycling systems use distillation and fractionation processes to remove
solutes from waste solvents, making it possible to re-use the IPA to wash parts. The recycled
IPA may still have small amounts of monomer in it. Recycling IPA reduces waste disposal costs,
emissions that are required to produce solvents, and the cost of purchasing IPA.
8.1.3 Disposal of electronic components
The symbol on the product, the accessories, or packaging indicates that this device shall not be
treated as nor disposed of with household waste. When you decide to dispose of this product,
do so in accordance with local environmental laws and guidelines. Dispose of the device via
a collection point for the recycling of waste electrical and electronic equipment. By disposing
of the device in the proper manner, you help to avoid possible hazards for the environment
and public health that could otherwise be caused by improper treatment of waste equipment.
The recycling of materials contributes to the conservation of natural resources. Therefore do
not dispose of your old electrical and electronic equipment with the unsorted municipal waste.
8.1.4 Disposal of packaging waste
Save the Form 3 packaging for transporting your printer. Original packaging is required for
warranty service and designed to be kept and reused for transportation or shipping.
The packaging is made of cardboard and plastic-based materials. Dispose of packaging
through your local waste and recycling facilities. By disposing of the packaging waste in the
proper manner, you help to avoid possible hazards for the environment and public health.
