3D Model Requirements
Below are some guidelines that need to be considered in order to have your models properly 3D printed. These are specific to PCBWay's system checks.
- File Size: 50MB maximum
- Supported file formats: .stl, .obj, .step, .stp
- Thinnest Part: 0.8mm
- Wall Thickness: 1.2mm
Models should be manifold (watertight) and not have any broken holes.
If you're making enclosures, consider the following guidelines
- Minimum wall thickness: 0.8mm
- Minimum snap fit clearance: 0.1mm
Print-in-Place
If you're making mechanical moving parts (AKA print-in-place) consider the following guidelines
- Minimum clearances: 0.3-0.4mm
- Minimum diameter: 2.2mm
- Minimum wall thickness: 0.8mm
In this double-hinged crank, the clearance between the surfaces creating the hinge is 0.4mm. The diameter of the pin is 2.2mm while the minimum thickness of the part is 1.6mm.
Snap Fit
In this snap fit enclosure, the wall thickness is 1.6mm. The clearance between the snap fit features are 0.15mm-0.2mm.
