As for the most important technical performance of 3D Printer, I personally think it is the printing precision/printing speed/materials scope/resolution ratio/color sorts. So compare your 3D Printing and see how great that could be. The company 2fprototypes whose 3D Printing can achieve the precision for 0.01mm, the materials scope from plastics to metal in FDM/SLA/SLS mode, the resolution ratio for 600dpi, even can make the multiple colors printing and fast printing. How about yours?
