Selective dissolution of polysulfone support material of fused filament fabricated Ultem 9085 parts

One of the main advantages of 3D printing lies in the fact that the desired object is constructed layer by layer, enabling the production of complex geometries otherwise unfeasible with conventional manufacturing methods. To create these parts, the use of an auxiliary scaffold structure, made of eit...
