Looking for a FDM 3D printer for a makerspace. What we have now are printers that are either sub-par, half built, or always out for repair. Want a highly reliable, solid performer under $2000. No wood parts, etc. From an established manufacturer with a good reputation. Turn-key operation, or as turn-key as can be expected for a 3D printer. Above average quality and capability. Strong user community. A model that an intermediate-level user would be quite pleased with. More materials than ABS and PLA would be desirable as would dual extruders, but are not absolute requirements. Your suggestions would be greatly appreciated!!!
