The UP! Plus 2 3D desktop printer has an open frame, all-metal black chassis and fabricates objects using 1.75 mm ABS (acrylonitrile butadiene styrene) or PLA (polylactic acid) thermoplastic filament (sold separately), with a vertical resolution from 150 to 400 microns (0.15 to 0.40 mm). The printer can build objects to maximum dimensions of 5.3 x 5.5 x 5.5 inches/135 x 140 x 140 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. An included platform-level calibration device can be used with the software to help ensure a level build surface. The software can also read the included nozzle-height detection device to calibrate the nozzle"s vertical position for accurate operation.The extruder has a heat and wind shield that helps prevent injury, and redirects air to help cool the material for a fine finish. A metal build platform heats to 105 degrees C to help provide thermal stability. A perforated cell board fastens to the platform by spring clips 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) resolution150, 200, 250, 300, 350, 400 microns (0.15, 0.20, 0.25, 0.30, 0.35, 0.40 mm)Build speed10-100 cm3/hBuild volume5.3 x 5.5 x 5.5 inches/135 x 140 x 140 mm (H x W x D)Printer weight5 kg (11 lb)Printer size350 x 245 x 260 mm (H x W x D)Power requirements100-240V AC, 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.
