Delta printers all have a relatively small and circular print area. This limits the build space significantly. The high speed of the printer makes the prints less accurate. In addition, it is little used as a home printer, as any problems encountered can be extremely difficult to fix and repair, not only because of the complex operation and lack of information, but because of the lack and overall cost of parts. The printer also needs a Bowden extruder to make the extruder light, which can limit the number of filaments that can be used. HERE a small example of operation.
