Materials for the voxeljet 3D printers
voxeljet offers following particlematerials for the 3D printers:
| MATERIAL | PLASTIC | PLASTIC | SAND |
|---|---|---|---|
| Particlematerial | PMMA | PMMA | Silica Sand |
| Binder-type | Polypor B* | Polypor C | Inorganic binder |
| Tensile strength | 4,3 MPa | 3,7 MPa | 220-280 N/cm² (Bending strength) |
| Yield point | 1% | 1% | <1% (Loss on ignition) |
| Burn-out temperature | 700° | 600° | - |
| Especially suited for | Investment casting | Investment casting, architectural models | Coreprinting for sandcasting |
| Advantages | sharp edges; for highest accuracy and true-to-detail | white color; dyeing; burns out very well | low emissions during casting; Environmentally friendly; no typical odour |
*only avaiable in Europe
