Microscale 3D printer manufacturer Boston Micro Fabrication (BMF) has released BMF Clear , a photopolymer resin rated at greater than 90% light transmittance. Designed for use on its 10µm and 25µm resolution printing platforms, the material is built specifically for applications where both optical performance and dimensional accuracy at the micron-scale are simultaneously required. That combination has been difficult to achieve in additive manufacturing because surface roughness at small feature sizes causes light to scatter and diffract before it clears the part. According to BMF’s technical documentation, BMF Clear prints at layer heights between 10 and 50µm and is compatible with both the company’s high-end industrial systems and the newly launched microArch S150 series .…
