Functional Prototype 3D Printing
Test real mechanical loads, thermal performance, and assembly fit with engineering-grade 3D printed prototypes.
Pedir OrçamentoWhen Visual Prototypes Are Not Enough
Concept models confirm shape and aesthetics, but they cannot validate snap-fit retention, bearing loads, or thermal cycling performance. Without functional testing, engineering teams risk approving designs that fail in the field — leading to costly recalls and redesign cycles.
Production-Equivalent Functional Prototypes
Print in the same class of materials you will use in production. Nylon delivers wear resistance and flexibility; PC-CF provides extreme stiffness at high temperatures; PA12 via SLS creates isotropic parts ideal for load-bearing assemblies. Every prototype is dimensionally accurate to within ±0.10–0.15 mm, giving you reliable test data before tooling investment.

Benefits of Functional Prototyping
Mechanical Validation
Test tensile strength, impact resistance, and fatigue life using parts printed in engineering thermoplastics with published datasheets.
Thermal Testing
Validate under-hood or industrial environments with materials rated up to 200 °C heat deflection temperature.
Assembly Verification
Check interference fits, snap-fit retention, and multi-part assemblies before committing to injection mold steel.
Regulatory Pre-Testing
Run internal compliance checks on functional prototypes to de-risk the certification process for the final production part.
Frequently Asked Questions
Which materials are best for functional prototypes?
Nylon (PA) and PA12 (SLS) offer excellent all-round mechanical properties. PC-CF is ideal for high-stiffness applications; PA-GF for high-temperature structural loads.
How close are 3D printed properties to injection-molded parts?
SLS PA12 produces near-isotropic parts with properties within 80–90% of injection-molded PA12. FDM nylon is anisotropic but can be oriented for specific load paths.
Can I run environmental tests on 3D printed prototypes?
Yes. ASA and PA-GF resist UV and moisture. PC-CF handles sustained temperatures above 130 °C. We can advise on material selection for your test conditions.
What tolerances can I expect?
FDM achieves ±0.15 mm; SLS ±0.10 mm; mSLA ±0.05 mm. For critical interfaces, we recommend designing with tolerance bands and verifying with first-article inspection.
How many iterations can I run cost-effectively?
With no tooling costs, each iteration costs only material and print time. Most customers run 3–5 functional prototype iterations before freezing their design.
