- Open PreForm - On the right-hand side, under "Model List" you can upload your file
Use the "Orient" button (top-left toolbar) to adjust part orientation. For multiple parts, drag them onto the sjbuild platform and arrange them to avoid overlaps. Can use the "Layout" button (top-left toolbar) to auto-layout the parts.
After orienting, use the "Supports" tool to automatically or manually add supports. This helps ensure the parts are printed successfully.
Select the desired layer height, depending on the print quality you need. In the right panel, you'll see the print settings section. Select the layer height from the dropdown menu, typically ranging from 25 microns (for higher detail) to 100 microns (for faster prints). (e.g., thicker layers for faster prints or thinner for higher detail)
Via Wi-Fi: Please ask your supervisor for assistance, as they will need to invite you to connect. Via USB: Export the file to a USB drive and then manually upload it to the printer.
For operating printer see procedure below
Formlabs Form 3L Printer Procedure
This SOP applies to all users operating the Formlabs Form 3L printer, ensuring consistent practices for printing, calibration, maintenance, and troubleshooting.
Safety Precautions
Wear non-reactive nitrile gloves when handling resin, resin-coated surfaces, or solvent. Use safety glasses to protect eyes from resin or support removal debris.
sopropyl alcohol (IPA) is flammable. Keep it away from heat or open flames and work in a ventilated area. Uncured resin is hazardous to aquatic life and can cause skin irritation. Avoid skin contact and never ingest. Follow local regulations for disposal of uncured resin, resin cartridges, and used solvents.
Resin Handling and Filling
Shake resin cartridges thoroughly before use. Insert cartridges into the designated slots on the side of the printer. Remove the protective valve cover, but do not remove the bite valve as it controls resin flow. Make sure the vent cap is open to allow proper resin flow.
Place the resin tank in its designated position inside the printer, ensuring it clicks into place. Insert the mixer, with its arms facing upward, into the tank.
Printing
Upload print files through PreForm software via Wi-Fi, Ethernet, or USB. Select the resin type and adjust print settings.
Once the resin is loaded, begin the print via the touchscreen. Monitor the print status through the interactive display for any errors or alerts.
Post Print
Unlock and remove the build platform by lifting it from the machine. Always use the two handles for proper grip
Use the Form 3L Finish Kit tools to clean and remove the print. Place prints in a rinse bucket filled with isopropyl alcohol or TPM to remove uncured resin. Wear gloves and protective equipment during cleaning.
Troubleshooting
Review the PreForm software to ensure the correct orientation and support structure were used. Clean the resin tank and glass optical window after any failed print to avoid contamination
Ensure the bite valves are not blocked or damaged. Verify the resin tank and cartridges are properly installed.
