Achieving true transparency at the micro scale has long been one of the most challenging requirements in precision manufacturing. Engineers designing microfluidic chips, optical components, and medical devices that demand both geometric accuracy and high light transmission have historically faced significant trade-offs — until now.
This webinar explores how BMF’s ultra-high-transparency CLEAR Resin is enabling engineers to prototype and produce transparent micro-scale components with greater than 90% light transmittance and 10-micron layer heights. For flat and near-flat geometries, the material delivers strong optical performance directly off the printer with no mandatory polishing or sanding — a particular advantage when working with microfluidics and small, delicate features where traditional finishing methods would be difficult or impossible. For curved or sidewall surfaces in the optical path, we’ll cover what to expect and how secondary finishing can be evaluated on a case-by-case basis. Gain practical insights into the material properties, achievable tolerances, and design considerations critical to working successfully with clear materials at the micro scale.
🔎Key topics covered:
- Material properties of BMF’s CLEAR Resin — light transmittance, haze, surface finish, mechanical performance, and biocompatibility
- How geometry and optical path affect apparent clarity, and why flat surfaces outperform curved or sidewall surfaces
- Design considerations and common pitfalls when working with clear materials at the micro scale
- Application examples across microfluidics, optical alignment features, light guides, and medical devices requiring visual inspection or fluid flow visibility
- How micro-precision 3D printing compares to traditional methods for producing transparent micro-scale components
