The PRISM Pro 3D printer is a professional-grade FDM printer based on a delta robot design. The main advantage of delta robot 3D printers is the speed of 3D printing. The speed of building a 3D model is 25-30% higher than that of 3D printers based on Prusa or Makerbot . Prism PRO is equipped with a closed case and a heated work surface, which allows printing with all available consumables (PLA, ABS, PVA, Rubber, HIPS and others). A huge working chamber measuring 400 x 400 x 800mm will allow you to create any prototypes for all cases of your business. Excellent quality 3D printing - 50 microns (0.05 mm), allows you to print 3D models with high detail and quality. Prism PRO is a 3D printer without borders, any ideas become reality with it. Prism PRO specifications: Material used for 3D printing: < / strong> ABS, PLA, HIPS, FLEX, Rubber, Nylon; Printing area (D, H): 400 x 800 mm Layer thickness: 50 -100 microns ( Layer thickness is controlled by printer software settings) ; Heated platform presence: < / strong> Yes; Closed chamber: Yes ; Number of printheads: 1 (possible nozzle diameters: 0.2 /,0.4/0.6/0.8/1.0/1.2) Software compatibility: Windows 7, Windows 8, MacOS, Linux; Print speed: up to 150 mm / sec; Supported formats: STL, GCODE Connecting a 3D printer to a computer: USB, SD (offline printing); Dimensions and weight: 625х715х1550, Weight - 60 kg Display availability: Yes Warranty: 1 year
