Say hello to my latest printer, the Elegoo Mars. This is an inexpensive (relatively speaking) SLA printer. This thing is amazaballs! It prints without build lines! I can, with very little prep, go from the printer to paint in just a few minutes. It is, however, not all rainbows and butterflies. These printers are almost always out of stock, it is a resin printer so it uses expensive resin and the slicer software is primitive at best. It uses an LCD screen and projected UV light to build parts layer by layer. The resin is photo sensitive to UV light and instantly hardens.
