Quality Standards
Published tolerances, surface finish, and inspection process for our in-house production technologies — powder bed fusion (SLS) and fused deposition (FDM) — plus the quality framework for partner-network manufacturing (CNC, injection molding, sheet metal, casting).
Quality Commitment
Every part that leaves our facility is inspected against the published specifications below. We stand behind our quality with a 100% satisfaction guarantee.
Dimensional Accuracy
Surface Finish
First-Pass Success Rate
Inspection Process
Pre-Print File Analysis
Mesh validation, repair, and printability assessment.
Build Preparation
Orientation review and process parameter verification.
Post-Processing QC
Visual inspection for defects, caliper checks on critical dimensions, and surface review.
Final Inspection
Complete part review before packaging and shipping.
Testing Standards
Dimensional Accuracy
Verified using calibrated digital calipers and measurement tools.
Surface Finish
Visual inspection for layer fusion, finish uniformity, and surface defects.
Material Consistency
Lot tracking and process parameter control keep material behavior repeatable from build to build.
Build Consistency
Maintained through regular calibration and preventive maintenance schedules.
Technology-Specific Capabilities
Tolerances and surface behavior differ by process. Use the appropriate tab for your selected technology.
Dimensional Capabilities
| Layer height | ~110 µm |
| Linear tolerance | ±0.3 mm or ±0.3% (greater of) |
| Hole diameter | +0.1 / −0.3 mm |
| Boss diameter | +0.3 / −0.1 mm |
| Minimum wall | 1.0 mm (3.0 mm for hollow parts) |
| Available materials | PA12, PA12-GF |
Surface Behavior
| All surfaces | Uniform matte, slight grain |
| Down-facing surfaces | No support marks (powder-supported) |
| Angled surfaces | No stair-stepping in either axis |
| Fine features | Min embossed/engraved 0.5 mm wide × 1 mm deep |
Partner-Network Manufacturing (RFQ)
CNC machining, injection molding, sheet metal, vacuum & die casting, and metal 3D printing are produced through our vetted partner network. Tolerances and finishes are confirmed per quote.
Quality Framework
- • Additive production partner is ISO 9001:2015 (quality management) and ISO 14001:2015 (environmental management) certified
- • Other partners selected against ISO 9001-aligned criteria
- • Tolerances per your supplied drawing (or PartGuys-supplied DFM)
- • First Article Inspection (FAI) reports available on request
- • Material certifications (mill certs, RoHS, REACH) available
- • PPAP / production-part approval supported for production programs
What to Expect
- • Quote usually returned within 1–2 business days
- • MOQs and lead times vary by process and partner
- • Inspection scope (sampling vs 100%) defined in the quote
- • Standard finishes called out on the quote; custom on request
- • Any non-conformance handled per the RFQ acceptance terms
Quality Guarantees
- Dimensional accuracy within published tolerances
- Defect-free parts with no printing artifacts
- Material consistency meeting specification
- Complete parts with no missing features
- Clean, professional surface finish
