New here? Here's the deal
Lab printers like the Prusa MINI+ aren't on the network, so once you hit print, the only way to check on it is to walk back. printsim is a stand-in: give it the same file you gave the printer, tap Start when the printer starts, and it rebuilds the print in 3D in real time, with how long is left and when it'll be done.
Live 3D buildThe printer moves and the layers stack up as they print, from your dorm or class.
Timelapse firstScrub or play the whole print at up to 1000× before you commit an 8 hour print.
