Which 3D printer do I choose?

Choosing a 3D printer can seem difficult and maybe even intimidating at first. It is important to understand the design limitations of each printer in considering which one would suit your project best. Other things to consider are what type of final look are you going for, how you are going to finish the part and how it is being presented.

Zcorp


  • Type of printing = Powder printing or CJP (Color Jet Printing).
  • Material = Cemented mineral powder
  • Material Properties = dense, somewhat brittle, plaster-like
  • Color = White , or any color that you can print in CMYK. A .VRML file needs to be submitted apposed to a .STL in order to print in color.


  • Cost =
    • $6.00 per cubic inch



  • Resolution = 0.0034 – 0.004 in.
  • Minimum effective wall thickness = 1/8 in. (minimum) open shells suggested
  • Maximum Print Volume = 8 in. x 10 in. x 8 in.



  • Benefits =Very good for printing large objects, molds and forms, architectural miniatures with the density of stone, prints high quality and full-color models. Extremely useful for quick, finished prototypes that need to be shown with little to no finishing.
