Grey Resin — Crisp Detail for Design and Concept Models
Grey Resin V5 is a versatile general-purpose SLA resin with a rich, matte grey finish. Its neutral mid-tone hides layer lines and shows off fine features and surface detail — the reason it is the most popular choice for design reviews and concept models.
Printed on our Formlabs Form 4, Grey Resin holds tight tolerances (±0.15%, down to ±0.02 mm) and delivers a balanced mix of stiffness and strength — 62 MPa tensile strength and 71 °C heat deflection. The V5 formulation prints three times faster than the previous generation with 30% higher impact strength.
Choose Grey Resin for form-and-fit prototyping, presentation models, general dental models, and jigs and fixtures. Upload your model to our instant calculator for a Grey Resin price in seconds.
