Original Prusa MINI - smart and compact 3D printing workhorse with all the bells and whistles you’re accustomed to when you buy an Original Prusa 3D printer. MINI will surprise you. :-) It has a print volume of 18 cm (7”) cubed, removable spring steel sheets, ethernet and optional Wi-Fi and it’s based on our brand new custom-made 32-bit Buddy mainboard with silent 2209 Trinamic drivers - Build Volume: Featuring a 7"×7"×7" (18×18×18 cm) build volume, the MINI is a fully-equipped 3D printer. Featuring sensorless homing, automatic Mesh Bed Calibration, replaceable nozzles, network connectivity, USB printing and a full-color LCD screen, the MINI is a big printer in a small body. - COLOR LCD SCREEN: Configure your 3D printer with ease and see previews of sliced models before you start printing! Thanks to the 2.8’’, 240×320 LCD screen with 65.000 colors, every option is just a few clicks away. - NETWORK CONNECTIVITY The MINI comes standard with an ethernet RJ45 port and optional future ESP Wi-Fi module upgrade. Send files to the printer wirelessly, or download OTA firmware updates. Thanks to the future updates you will be able to manage a whole print farm easily. - GEARED EXTRUDER To decrease the weight of the extruder, we moved the extruder motor on the Z-axis column. Using a 3:1 drive gear ratio, the printer pushes the 1.75 filament strand through a PTFE tube into the hotend and through the 0.4mm nozzle.
