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.
Claims13
A method of manufacturing a 3D printed object comprising:
- 3D printing the 3D printed object;
- controlling pores and a surface roughness at an outer surface of the 3D printed object by selective application of a fusing agent, a detailing agent, or combinations thereof during the 3D printing;
- condensing solvent vapour on the outer surface of the 3D printed object, thereby forming a condensed solvent, wherein the 3D printed object comprises a polymer and a radiation absorber, and wherein the outer surface of the 3D printed object a) comprises the pores that absorb the condensed solvent and b) has the surface roughness of greater than 5 Ra (μm);
- and
- dissolving a portion of the 3D printed object to tailor the surface roughness of the 3D printed object to a value of from 0.5 Ra (μm) to 4 Ra (μm).
