Manufacturing Specifications
Print tolerances, materials, and file standards
Follow these engineering guidelines to get clean, dimensionally accurate prints on the first run.
Mesh standards
Geometry & mesh integrity
- Export as watertight binary STL or 3MF format
- Check non-manifold edges before submitting
- Minimum wall thickness: 0.8 mm (FDM), 0.4 mm (SLA)
- Align primary structural stresses parallel to layer orientation
Dimensions
Scale & unit verification
- Set CAD working units strictly to millimeters (mm)
- Maximum single-piece build envelope: 300 × 300 × 300 mm
- Interlocking parts require 0.3 mm radial clearance
- Standard dimensional tolerance: ±0.15 mm
Overhangs
Surface & support design
- Self-supporting overhangs up to 45° require no support
- Horizontal bridging reliable up to 12 mm span
- Threaded brass heat-set inserts: 0.2 mm undersized pilot holes
- Chamfers preferred over bottom-edge fillets to avoid elephant's foot
Technical properties & density profiles
Match your part requirements with our certified production materials and infill setups.
| Material Type | Tensile Strength | Max Temp (HDT) | UV Resistance | Recommended Applications |
|---|---|---|---|---|
| PLA+ (High Speed) | 55 MPa | 55 °C | Moderate | Visual prototypes, desk fixtures, snap-fit casings |
| PETG (Engineering) | 50 MPa | 70 °C | High | Functional brackets, outdoor enclosures, chemical-resistant jigs |
| ABS / ASA | 43 MPa | 95 °C | Very High (ASA) | Automotive brackets, high-temp mounts, UV-exposed hardware |
| TPU 95A (Flexible) | 35 MPa | 60 °C | High | Gaskets, vibration dampeners, impact-absorbing bumpers |
Prevent common CAD export pitfalls
Ensure all mesh modifiers are applied and outward surface normals are uniform before exporting. Unjoined multi-body components may lead to sliced slicing voids.
