The 3D printer works with 3D data files in ZBD or STL (stereolithograph) format. These files can be created with popular commercial programs like AutoCAD or Rhino3D, SolidWorks, or 3D Studio MAX . Using ZBD or STL files as source data, the machine â€œprintsâ€ cross-sections of your model on a bed of plaster dust, using a sugar-water binding agent instead of ink. Wherever the binding agent touches the plaster, the dust hardens, creating a solid cross-section of the digital model. The printer continues adding and hardening layers of dust until the model is complete. The model is then excavated from its bed of plaster dust and gently air-cleaned.
