Comparing the Requirements
Although there additional printing processes, such as Binder Jetting, we don't have to discuss them all to understand how the process and the material can impact your design. Your decisions about overhangs, detail size, and wall thicknesses all vary with the final material and process. To serve as some starting guidelines, a summary of the three processes we did discuss are:
| Design requirement | FFF/FDM (0.4mm Nozzle) | SLA (Form2 at 0.10 Layers) | SLS (Shapeways Strong & Flexible Plastic) |
| Minimum supported wall thickness | 1mm | 0.4mm | 0.7mm |
| Unsupported wall thickness | 2mm | 0.6mm | 0.7mm |
| Overhangs | 45 degrees or less | 71 degrees or less | Any |
| Height of unsupported overhangs | 0.5mm | 1mm | Any |
| Minimum detail (vertical faces) ... |
