I assembled a kit for a
Prusa MK3, so now I have two 3D printers (I bought a Monoprice Mini Delta late last year). This thing is a massive upgrade over the Mini Delta in every possible respect - more accurate, more consistent, much quieter, far larger build area, better interface,
far better documentation and support.
The Mini Delta is cheap and actually can do very good quality, but the build area is very small and I had a devil of a time getting it to be dimensionally accurate and consistent - it's very difficult to get something larger than an inch or so on an axis to print truly square, for instance, and you might get slightly different dimensions when printing the same model twice in a row. There's a very active user community for the Mini Delta, with tons of guides on how to improve calibration and get better results, and that helped some, but I was spending too much time thinking about how I would want to try printing "X" if I could just get the tolerances good enough first.
If I was just looking to print minifigures or the like, the Mini Delta would suit me fine, but I'm glad I've upgraded. Thinking I should contact the local technical school and see whether they might have a use for it.
