FormLabs Form 1 Leveling Jig

If you re-pour your PDMS layer, make your own vats, or use 3rd party vats with your Form 1, chances are your build platform can use a good leveling.

This calibration jig places four 10mm x 1mm disks in the corners, and one 20mm x 1mm disk in the middle of your build platform.

Calibration means that the build platform is parallel to the surface of the PDMS layer of your vat, and at the nominal distance. This procedure is not difficult, but does require patience, steady hands, and attention to detail.

Calibration in Summary
1. Print the calibration jig.
2. Remove disks one at a time, and measure the thickness using a caliper.
3. Use a 7mm wrench to adjust the leveling nuts in each corner.
4. Print the calibration jig again.
5. Measure disk thickness again.
6. Adjust leveling again if needed.

A few words on leveling with the 7mm wrench. Leveling is adjusted by tightening or loosening the four Nylock nuts located in the four corners of the tilt platform, under the vat. A
