Footnotes
¹ Using Alpha Fast Resin and 250 µm layer height on the Form Studio 1. Using Fast Model Resin and 200 µm layer height on the Form 4 Series. Using Draft V2 Resin and 200 µm layer height on the Form 3 Series. Based on actual print times from a collection of test parts covering common engineering, product design, manufacturing, and dental applications. Based on the 75th percentile actual print speed from reported prints in 2026.
² Average across all materials printed at 100 µm layer height, weighted by material popularity. Print speed will vary depending on the material, layer height, and part geometry. The range is based on the materials with the slowest median print speed and highest median print speed.
³ Using Alpha Grey Resin and Grey Resin V5, printed at 100 µm layer height, post-cured for 5 minutes at room temperature. One test model with various feature sizes 3D printed on three different printers.
⁴ Using 50 µm layer height. Tested using a full arch restorative model with dies, four models per print job, printed on three different printers, and post-processed according to the recommended settings.
⁵ Actual achievable part size may be slightly smaller than the build volume, accounting for minor shrinkage during printing and part orientation. If you are printing a job that is taller than 19.0 cm (7.5 in) on Form 4/B, taller than 30.5 cm (12 in) in) on Form 4L/4BL, or taller than 18.5 cm (7.2 in) on Form 3/B/+, you have to remove the resin tank while removing your print. PreForm will warn users when their job is above these limits.
⁶ Assuming a part printed on supports that resembles a rectangular prism with 12.5 cm depth and 1 cm height.
⁷ XY resolution describes how precisely the printer can cure the resin in the XY (horizontal) plane. It corresponds to the pixel size of the Light Processing Unit 4, Light Processing Unit 4L, and Light Processing Unit S1.
⁸ Layer thickness availability varies by material. View our materials compatibility table to confirm availability.
⁹ Languages beyond English will come in future firmware releases on the Form 4 Series and Form Studio Series.
¹⁰ The exact lifetime of an individual resin tank depends on layers printed, physical wear, and accidental damage.
