Clear Resin
Clear Resin — Crystal Clear.
Light-Transmissive.
Clear Resin is our transparent photopolymer, delivering near-optical clarity and excellent light transmission. Ideal for lenses, light guides, fluidic channels, transparent housings, and any application where transparency is a functional or aesthetic requirement.

About Clear Resin
Clear Resin is a transparent 405 nm photopolymer formulated for a special low-refractive-index base, delivering 92% light transmission for bubble-free clarity. Tensile strength runs 28–38 MPa with 14–18% elongation at break — tougher and more resilient than a typical clear resin. A triple defence system (anti-yellowing agent, UV absorber, antioxidant) keeps parts from ambering with age.
We print your Clear Resin parts at layer heights as fine as 0.05 mm on professional SLA machines. Transparency is maximised through a careful post-processing protocol: IPA wash, UV post-cure, and optional wet-sanding and polishing to near-optical finish. Its ~1.195 g/cm³ density and low viscosity ensure consistent fill of fine features.
Clear Resin is the choice for light guides, lenses, display covers, transparent enclosures, fluidic channel prototypes, and any part where visual transparency is a core requirement. It can also be used for casting masters where downstream transparency in the final material is needed.

Design Guidelines for Clear Resin
Clear Resin is ideal when optical transparency is the requirement. For opaque display parts with fine detail, Standard Resin in grey is more forgiving. For functional clear-ish parts needing toughness, Tough Resin is available. For large clear parts, our FDM PETG service offers a cost-effective alternative.
