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, which is why 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.
