About zPrinter 450
The zPrinter 450 developed by Z Corporation (acquired in 2012 by 3D Systems) is a fused deposition modeling (FDM) machine also known as a 3D Printer. The zPrinter 450 uses inkjet heads from HP to extrude a water based binder solution onto thin layers of a plaster based substrate. Each layer of plaster is 0.0035 inches which is thinner than a standard sheet of 20 pound printer paper. The addition of a tri-color HP cartridge allows for full range color printing rather than the standard white of the zPrint powder.
- General Stats:
- Material : Plaster (CaSO4)
- Maximum Part Size : 203mm x 254mm x 203mm (8in x 10in x 8in)
- X/Y Resolution : 300 x 450 dpi
- Layer Thickness : 0.089mm (.0035in)
- Main Article : Processing zPrinter Files
- We will only process STLs which have:
- 1 shell per continuous part
- 0 border edges
- 0 invalid orientations
- 0 holes.
- Geometry should have a minimum wall thickness of 2mm for “best chances” to survive post processing.
Even if Netfabb reports no invalid orientations, if we see red triangles in repair mode there is a problem with your model. Print at your own risk. If you are unsure of a model in NetFabb and want to see how it is perceived by the zPrinter we can process it in zPrint.
Fixing a File
- Main Article : Fixing STLs
Students are welcome to use any of our computers for fixing their files in Netfabb or Rhino.
- Here are some tips to get you started at home:
- Ideally in Rhino you want one closed polysurface before meshing.
- NetFabb is better at meshing than Rhino. Consider opening the 3dm file in NetFabb to generate the STL instead.
- Default repair is decent at fixing holes, border edges, and invalid orientations. Then try using boolean join to reduce shells down to 1.
- If boolean join results in multiple shells then most likely the shells are not contiguous. Consider deleting extra shells in model.
- Extended repair wraps an existing STL in a new mesh. This can severely alter geometry and result in thin walled sections.
You can color your model in the zEditPro Software or export a VRML file from your favorite CAD software. VRML files must be saved as Version 2 with texture coordinates exported. Since there is no black color cartridge, any black on your model will be a high density mix of CMY and may appear as thin stripes of those colors. We cannot guarantee color accuracy.
Coloring in zEditPro
- Main Article : Coloring in zEdit Pro
- From Paint and Texture Model mode, you may either apply colors or a texture (image) to your model:;
- For coloring: you may color triangles, surfaces, shells, or the entire part. Right click to apply your changes.
- For texturing you can apply it to visible surfaces or your whole model. You may also apply the texture as a straight projection or wrapped around the model.
- Right click to preview changes and right click to apply.
Infiltration is a pretty straightforward process, the printed parts from the Zprinter are very fragile in order to make the part more durable the part is submerged in a infiltrate fluid. It is essentially super glue which is designed to rapidly strengthen parts. It is a no-odor, non-blooming resin, that can be easily sanded and painted. Not only do you get strong parts, but Z-Bond enhances the vibrancy of models printed with color.
