Challenge:
A client required the mass production of small, cube-shaped mechanical couplings with intricate internal spline geometries. Traditional injection molding was cost-prohibitive due to high tooling costs for this batch size, while standard FDM printing could not achieve the necessary dimensional precision or smooth surface finish for the internal teeth.
Solution:
We utilized Industrial SLA (Stereolithography) technology to print these components in high-performance resin.
· Material Versatility: We produced batches in both Matte Black Resin (for UV resistance and aesthetic contrast) and Standard White Resin (for high detail visibility).
· Precision Engineering: The additive process allowed for the creation of complex internal splines without support structures inside the holes, ensuring perfect fitment.
· Scalability: By optimizing the build platform density, we achieved a rapid turnaround for large quantities, bridging the gap between prototyping and mass production.
Results:
· High Precision: Achieved tight tolerances (±0.1mm) essential for the coupling mechanism to function smoothly.
· Superior Surface Finish: The parts emerged with a smooth, matte texture, requiring minimal post-processing.
· Cost Efficiency: Eliminated mold costs entirely, reducing the total project budget by 40% compared to low-volume injection molding.
