Abstract:
A method of treating a porous plastic rapid prototype having a rough surface with miniature steps to obtain a desired surface appearance, said method comprising:a) infiltrating the pores of said plastic prototype with a curable polymer; b) curing said polymer to form an infiltrated surface on said plastic prototype with a surface roughness (Ra) of 7-10 &mgr;m; c) applying an external coating of a curable polymeric hardener, on said Infiltrated surface, said hardener having sufficient viscosity to remain on said infiltrated surface end to fill up said miniature steps to form a surface without said miniature steps: and d) curing said hardener to obtain a matt surface with surface roughness (Re) of 0.2-0.7 &mgr;m.
