What is Formlabs Rigid 4000 Resin? 

Formlabs Rigid 4000 resin is a white, glass-filled SLA material with high stiffness and resistance to deformation. It produces strong parts with a smooth, matte finish and is well suited to thin-walled geometry. The glass reinforcement helps parts resist bending under load.

Formlabs Rigid 4000 Overview

Applications

Formlabs Rigid 4000 resin is a white, glass-filled SLA material with high stiffness and resistance to deformation. It produces strong parts with a smooth, matte finish and is well suited to thin-walled geometry. The glass reinforcement helps parts resist bending under load.

Key Product Benefits

  • Glass-filled stiffness
  • Smooth, matte surface finish

Tolerances

For well-designed parts, dimensional accuracy of ±0.3% of the nominal dimension, with a minimum tolerance of ±0.3mm (±0.012 in.), can typically be achieved. Tolerances may vary depending on part geometry.
