FormLabs Resin Precision Model
Precision Model Resin is a high-precision SLA resin specifically developed for the Form 4 series (Form 4, 4B, 4L, 4BL). Ideal for restorative dental models, it offers a matte beige finish that mimics the appearance of plaster, providing sharp margins and making it easier to read and clinically inspect.
Main advantages
-
Top-of-the-line accuracy : Over 99% of the printed surface is within ±100 μm of the digital model; ~95% of the surfaces within ±50 μm
-
Production speed : Print 8 models in just 90 minutes (layer height 50 μm), thanks to the Form 4 ecosystem that is up to 3× faster than previous formulations
-
Chalky finish : opacity and matte surface improve visualization of margins, useful for clinical control and presentations
-
High reliability : Part of the integrated Form 4 system, it ensures a constant print flow without interruptions
-
Rapid workflow : post-wash in isopropyl alcohol 5 min + post-curing 5 min at 35 °C at room temperature
Recommended Applications
-
Restorative models (crowns, bridges, implants)
-
Diagnostic and fit tests
-
Models for precision testing or implant drilling
-
Any scenario where tolerances ≤ 100 μm are required
