Custom brass CNC machining offers high precision, excellent machinability, and fast turnaround for industries like automotive and electronics. SG PROTO delivers tight tolerances up to ±0.01mm, multi-axis machining, and complete finishing solutions for prototypes and small-batch production.

Nylon 3D printed parts often have a rough, porous surface, especially with SLS and MJF technologies. This article explains how vapor smoothing improves surface finish, enhances mechanical properties, and delivers professional-quality results. Discover why vapor polishing is the ideal post-processing solution for functional prototypes and end-use nylon parts.

From design to delivery, SG PROTO offers a fully controlled prototyping workflow. Our process includes material sourcing, engineering review, precision machining (CNC, 3D printing, vacuum casting), surface finishing, and final inspection—ensuring every part meets exact specifications in both function and appearance.

High-precision CNC machining of aluminum parts ensures lightweight strength, tight tolerances, and superior surface finishes. From rapid prototypes to complex geometries, our advanced machining capabilities deliver reliable, high-performance aluminum components for aerospace, automotive, and industrial applications.
