There seems to be a lot of different materials used in 3D printing, many I am not familiar with. I don’t know if styrene is useable in this process. I have come across many 3D printed items not available as resin castings or as styrene parts I would love to have, but I don’ t want to shell out for something that might not last! Conceivable these parts could be used as masters for reproduction in resin, but that seems like an extra step that not all of us are able to do. Has anyone out there NOT had issues with breakdown, and if so, do you know the material? Painting does not seem to seal the parts to prevent deterioration and there could also be incompatibility issues between regular model materials (styrene, resin). I would like to hear more input from modelers who have purchased these parts and people who do 3D printing. This is such a promising addition for modelers but it seems to have some teething problems.
