About the MINI+
The MINI+ carries Prusa's reputation for reliability and thorough documentation into a smaller, lighter machine for makers who do not need the build volume of the MK4S.
It uses a Bowden extruder with 3:1 gearing, which suits PLA and PETG well. Flexible filaments such as TPU are harder to push through a Bowden tube, so print them slowly or choose a direct drive printer. The 180 × 180 × 180 mm build volume matches the Bambu Lab A1 mini, and magnetic spring steel sheets are available in smooth, textured and satin finishes.
Prusa develops the printer, the firmware and PrusaSlicer, so the built-in MINI+ printer profiles are a solid base. For OzFDM PLA+ or PETG+, start from PrusaSlicer's generic material profile and adjust the temperatures to the range on the product page.
Prusa sells the MINI+ semi-assembled, currently with an enclosure bundle. It has an Ethernet port and USB, with Wi-Fi available as an optional module. Finishing the assembly yourself teaches you how the machine works, which helps with troubleshooting later.
