Industrial prototypes, 5-axis CNC secondary finishing, and custom additive components validated under ISO 9001 quality frameworks.
Achieving absolute transparency in additive stereolithography (SLA) requires precise control over photopolymer molecular kinetics, UV exposure wavelengths, and nanometer-scale surface finishing.
Standard SLA polymers often suffer from internal yellowing and optical haze caused by incomplete radical polymerization and micro-void scattering. Our optical formulations maintain an Abbe number of 56 and a refractive index (nD) of 1.51–1.53, matching PMMA and optical borosilicate glass for high-transmittance optical light guides and internal sensor lenses.
By pairing high-resolution solid-state 355nm quasi-continuous UV lasers with proprietary focal spot compression down to 0.075 mm, our industrial SLA equipment eliminates staircase stepping. Build layer thicknesses can be set between 0.025 mm (25 microns) and 0.05 mm, ensuring layer-to-layer cohesion without boundary scattering.
Raw transparent prints exit the build envelope translucent. Our post-processing cleanroom deploys automated ultrasonic tripropylene glycol monomethyl ether (TPM) washes, controlled thermal flood-curing in inert nitrogen atmospheres, wet rotary mechanical sanding up to 5000-grit, and specialized optical polyurethane UV clear-coating.
