Priming a printer and starting a remote print (SLA)

Priming a printer and starting a remote print (SLA)

Print on-the-go with just your computer. You can insert consumables, send a print job, and start the print from anywhere.

Note:

Remote printing requires a Formlabs account and that your printer be connected to the internet.

Readying a printer for a print

A printer is ready to print once you insert the required consumables, including a resin cartridge, a resin tank, and a build platform. The resin tank must be unused, or its resin type must match that in the resin cartridge.

Form 4 and Form 4L generation

  1. Insert a resin cartridge and open the vent cap.
  2. Insert a matching or unused resin tank.
  3. Insert and lock the mixer. A confirmation message appears. If the mixer is inserted and properly secured, tap Yes.
  4. Insert a build platform. A confirmation message appears. If the build platform is locked and free of any previous prints or other cured resin, tap Yes.

Priming a local printer (deprecated)

Note:

Priming a printer is a deprecated feature for Form 3, Form 3B, Form 3L, and Form 3BL printers. It is only available for Form 3/Form 3B printers running firmware versions 1.20.33 or earlier and Form 3L/Form 3BL printers running firmware 1.11.14 or earlier. The feature has been replaced with automatic printer readying.

Prime a printer without enabling Remote Printing to automatically start a print when your computer is on the same network. As long as a printer is Primed beforehand, you can send a print job to the queue and have it automatically begin printing from several rooms away.

  1. Insert consumables as described above.
  2. Tap Prime on the Home screen. The printer’s touchscreen and PreForm status both display as Primed.

Note:

If you are away from your printer or connected to a different network, then the primed printer is disabled in PreForm and the print job does not upload to the printer queue. Enable Remote Printing to print from a different network than your printer.

Setting up remote printing

When remote printing is active, the printer does not communicate with PreForm directly. Instead, both PreForm and the printer pass information to Dashboard and Dashboard shares information between the two.

Ensure you’re all set up and ready to go before sending a print job to the printer:

  1. Enable remote printing:
    • Form 4 and Form 4L generation: Tap Settings > Connectivity > Remote printing and monitoring on the printer’s touchscreen.
    • Form 3 and Form 3L generation: Tap Settings > Connectivity > Remote Printing on the printer’s touchscreen.
  2. Log in to a Dashboard account
  3. Register your printer to your Dashboard account:
    • Form 4 and Form 4L generation: Tap Settings > Connectivity > Remote printing and monitoring > Add printer to account on the printer’s touchscreen.
    • Form 3 and Form 3L generation: Tap Settings > Connectivity > Register to Dashboard on the printer’s touchscreen.
  4. Insert, secure, and confirm the status of all required consumables: a build platform, a resin cartridge, and a resin tank and mixer. The printer’s status switches to Ready (Form 4 and Form 4L generation) or Ready To Print (Form 3 and Form 3L generation). 
    • For Form 3/Form 3B printers running firmware versions 1.20.33 or earlier and Form 3L/Form 3BL printers running firmware 1.11.14 or earlier: On your printer’s Home screen, tap Prime. The printer’s touchscreen, PreForm status, and Dashboard status all display as Primed.

Starting a print

Form 3 automatically starting a print
  1. Open PreForm and click Account to log in to your Dashboard account within PreForm.
  2. Add or select your primed printer. 
  3. Set up your print job in PreForm and click Print Now (available in PreForm 3.29.0 and later). The print job is uploaded to the printer, which starts the print automatically.
  4. Check on your print’s progress in Dashboard.

Note:

You must be logged in to the same Formlabs account within PreForm to see your remote printer in PreForm.

After a print

After a print completes, the printer status changes to Idle. The build platform status on the printer screen changes to Remove parts.

Idle Form 3 after a print

Remove the build platform and retrieve your printed parts. To ready your printer again, insert the necessary consumables and confirm that they are ready to print.

Disabling automatic readying (Form 3 and Form 3L generation only)

You may want to disable automatic readying, for example if you want to leave your consumables in your printer without it automatically starting a print or if you are in a multi-user environment and want more control over printing. To disable automatic readying:

  1. Tap the gear icon on the touchscreen. The Settings screen appears.
  2. Tap System > Printer Details > Subsystems. The Subsystems screen appears.
  3. Toggle Automatic Ready to Print off. A confirmation screen appears.
  4. Tap Confirm to disable automatic ready to print.
