5.2.4 Pre-Print Checks
The printer checks the following before each print job:

• Accessories – Sensors check for the proper installation of the resin tank, build platform, and resin cartridge.
• Temperature – The print chamber and resin heat to around 35 °C. A heating fan blows air 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.
Moving parts. Do not open the printer cover until the touchscreen indicates the print is complete.
Finishing
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.
   IPA is flammable. Keep containers closed, and keep out of the reach of children.

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 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.
5.4.5 Power Off the Form 3
Turn off the Form 3 completely when moving or storing the printer and to conserve power. To turn off the Form 3 completely, disconnect the power cord from the power source.
5.5 Emergency and Exceptional Situations
Formlabs has made every effort to provide updated Safety Data Sheets (SDS) for every resin product, in accordance with the latest government guidelines. Always consult the SDS as the primary source of information to understand safety and handling of Formlabs materials.
In an emergency involving resin, always refer to the Safety Data Sheet (SDS) and/or seek help from a medical professional.
When handling IPA, always consult the safety Data Sheet (SDS) from the IPA supplier as the primary source of information. Handle IPA with gloves in a well-ventilated area.  Keep away from heat, sparks, and open flame. IPA evaporates rapidly, so keep the rinse tub and bottles closed whenever possible.
Promptly clean and inspect the printer after a resin spill to minimize any cosmetic or functional damage to the printer. If you have experienced an accidental resin spill, document the problem with photos and clean the printer as best as possible. Contact Formlabs or a certified service provider as soon as possible.

6.1 Inspecting the Product
6.1.1 Before Each Print

6.1.2 Monthly

6.1.3 Every 3 Months

6.2 Inspection Tasks Between Prints
6.2.1 Inspect the Bite Valve
The bite valve is 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 the cartridge dispense arm squeezes the valve open.
When switching to a different 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 the bite 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.

Do not bend the spring fingers when cleaning. Ensure that any IPA on the ID chip dries completely before continuing printing.

Disposal

8.1 Guidance for Recycling and Disposal
Refer to the Safety Data Sheet (SDS) and local authorities for guidance on disposing of IPA.
8.1.1 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 off 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 effective 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.

8.1.2 Disposal of IPA and solvents
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.
3. Inform your waste disposal service that your bottle contains IPA with small amounts of 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 offers a costeffective 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  olvents, 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.

Glossary

exposure to the laser and protects the resin from curing due to ambient light.
Bite valve| This flexible seal regulates resin dispensing. Resin flows out when the cartridge dispense arm squeezes the valve open.
