Paper is generally not considered as a suitable printing medium for digital fabrication processes. However, several techniques and measures are available to overcome the intrinsic disadvantages of plain paper. The most important is extrusion coating with a thermoplastic resin, giving, beside other advantages, a mechanical smooth and chemical inert surface.
