So called “smart 3D printer” is a great option for a variety of users. Beginners buying it as a first printer will definitely appreciate the low price of 349 US dollars and extremely easy 3-piece assembly process. That’s the same factor that attracts owners of printing farms.  Except for that, Prusa MINI reliability makes it really suitable for this role. In this printer you can find three thermistors and a high-quality power supply. You can also expect 24/7 live chat and great overall support as for every other Prusa product.  And it is open source!

Build volume of MINI is 18x18x18 cm on replaceable spring steel sheets. Printer is equipped with a custom 32-bit mainboard and firmware updater. LCD display makes using the device really easy. The printer has sensorless homing with Trinamic 2209 drivers and a custom hot end supporting E3D nozzles. Innovative feature is the requirement of physically breaking part of PCB to flash new firmware onto the board. This was introduced to make sure users are aware of voiding the warranty of the printer.
