The surface properties of industrial 3D printing technologies vary greatly. We provide a short overview for the most important technologies, incl. Ra and Rz values by technology, post processing methods and sample images.
Fluid tightness is an often-discussed topic in 3D printing. While industrially manufactured laser sintering parts are rather porous and therefore often not water tight, HP’s multi jet fusion technology generates parts that are fluid tight without further processing. This article provides an overview of the part characteristics, incl. wall thickness and geometry recommendations.
