Abstract
The present disclosure relates to a method of manufacturing a 3D printed object. The method comprises condensing solvent vapour on an outer surface of the 3D printed object. The 3D printed object comprises polymer and radiation absorber. The outer surface of the 3D printed object a) comprises pores that absorb the solvent and b) has a surface roughness, Ra, of greater than 5 μm. The method also comprises dissolving a portion of the 3D printed object to tailor the surface roughness, Ra, of the 3D printed object to a value of from 0.5 to 4 μm.
