The UP! Mini 3D desktop printer has an all-metal enclosure and fabricates objects using 1.75 mm ABS (acrylonitrile butadiene styrene) or PLA (polylactic acid) thermoplastic filament (sold separately), with a vertical resolution from 200 to 400 microns (0.20 to 0.40 mm). The printer can build objects to maximum dimensions of 4.75 x 4.75 x 4.75 inches/120 x 120 x 120 mm (H x W x D). The included printer management software runs on a Windows or Mac OS X computer, reads Standard Tessellation Language (STL) files generated by computer-aided design (CAD) software (sold separately) and commands the printer through the provided USB cable.The enclosure guards against room drafts to help minimize temperature fluctuation, and helps reduce operational noise and odor. A build platform heats to 51.4 degrees C to help provide thermal stability. A perforated cell board is held to the platform by full-side mounting channels for a secure fabrication base. Solid metal guide rails and precision slide bearings help ensure precise movement. The belt-driven stepper motors meet the National Electrical Manufacturers Association (NEMA) standard ICS 16-2001.SpecificationsPrinting materialABS or PLAVertical (Z-axis) resolution200, 250, 300, 350, 400 microns (0.20, 0.25, 0.30, 0.35, 0.40 mm)Build speed10-100 cm3/hBuild volume4.75 x 4.75 x 4.75 inches/120 x 120 x 120 mm (H x W x D)Printer weight5 kg (11 lb)Printer size14 x 9.5 x 13.25 inches/350 x 240 x 350 mm (H x W x D)Power requirements100-240VAC, 50-60Hz, 200WInput formatSTLOperating systems supportedWindows XP/Vista/7, Mac OS X *H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.3D printers fabricate physical objects directly from computer-aided-design (CAD) data sources. Objects created by additive manufacturing are built by dispensing successive thin layers of molten material onto a moving platform base from a robotic extruder nozzle. The material is most commonly a thermoplastic or HDPE (high-density polyethylene) filament.PP3DP manufactures UP! brand portable 3D printers and accessories.
