Clear Resin — Transparent SLA Parts with Optical Clarity
Clear Resin V5 is an exceptionally clear, colour-neutral SLA resin. Straight off our Formlabs Form 4 it is translucent; polished or coated, it reaches near-optical transparency that rivals acrylic — the only material in our range that lets light through.
Beyond looks, Clear Resin is stiff and strong (60 MPa tensile strength, 74 °C heat deflection) and prints with very low odour. The V5 formulation prints three times faster than V4, with double the elongation at break and 25% higher impact strength.
Use Clear Resin for transparent enclosures, optical and lighting components, fluidic devices, rapid tooling, and any part where you need to see inside. Upload your model to our instant calculator for a Clear Resin price in seconds.
