Contact Formlabs Support or your authorized reseller for additional product support.
Next steps
Once you’ve set up your Form 4L, download PreForm to your computer and start printing.
Prepare a file for printing
After downloading PreForm, read the support articles on designing successful 3D models and using PreForm to learn more about the software and preparing models for printing on Formlabs SLA printers.
If this is your first time using PreForm, an onboarding tutorial will appear and walk you through the software’s capabilities. Click Help > Show Onboarding Tutorial to review this information at any time.
Send your file to the printer
When you’re ready, send your print to your Form 4L or print a job remotely and start printing.
Start a print
If you inserted a resin tank, resin cartridge, and build platform into your Form 4L during the setup process, the printer should be ready to print and will start automatically. If not, confirm the print on the printer touchscreen to start.
Finish your printed part
Once the print is complete, remove the build platform from the printer, wash any remaining liquid resin off your printed part, and post-cure and remove supports as necessary. Read the support article on SLA basic finishing steps to learn more.
Between prints
Between prints, be sure to keep your Form 4L clean, paying particular attention to spilled resin. Handle the Form 4L resin tank with care to ensure print success and printer reliability.
Notice:
If you leave the build platform on its mount and power off the printer, the build platform will slowly lower under its own weight. This includes power cycling during a firmware update. If the build platform has any sharp printed parts on it, this could damage the resin tank or Light Processing Unit. To prevent this, remove the build platform from the printer before turning it off, particularly if there are still any parts on the build platform.
