As an owner and user of a 3D printer, I don't expect the scene to get to regular household users within the next 5 years. Difference in material qualities can totally influence how you prepare the models for printing. For example, after I switched to a less brittle PLA filament, breakaway is totally different. The model may have less opportunities for failure during printing, but the plastic is less convenient to remove after the print is finished. Further sanding is needed for breakaway spots and arbitrary extrusion defects. I also find that super glue is a bad idea for assembling what is larger than can be printed at once. On a side note, if there were an automated solution for breaking apart a model, adding peg holes or woodwork inspired nailless/screwless mesh finger pegs would really fulfill a need for users with small economic 3D printers
