Three-dimensional printing of three-dimesional objects

This describes a 3D-printed object with a unique surface finish. Instead of a smooth or typically rough texture, its outer layer is made of many tiny, curved, overlapping tiles that form a distinct microtextured pattern. This special surface can also be very smooth, with a roughness of 50 micrometers or less.

Why it matters: Since 2022, advancements in powder bed fusion 3D printing and energy beam process control have made it more feasible to precisely create complex surface microstructures and achieve specific roughness levels as claimed. This could enable more consistent production of objects with the described tiled surface.
