Infiltrants and roughness of 3D printed models

3D printing developers persistently introduces new base materials and various strengthening infiltrants. Professional users need detailed information about properties of 3D printed models and they often ask about surface roughness. Therefore in this paper we have tested roughness of 3D printed samples strengthened with usual but also with alternative infiltrants. In order to estimate possible enhancement, after initial roughness measurement raw samples were sanded and roughness were measured again The lowest average roughness was obtained for samples infiltrated by cyanoacrylate, followed by wax and Protektin. The highest average roughness was for water and for epoxy resin. Sanding of samples had lowered roughness significantly for water and epoxy resin, thereby leveling it to values of other infiltrants. For other infiltrants, sanding had not provided noteworthy improvement of roughness.
