Finish Included in Turnaround All finishing options are factored into our 5-day turnaround. No hidden delays — your parts arrive complete and ready to use.
Color Range
UV Powder Coating
Electrostatically applied powder cured under UV light. Produces vibrant, hard-wearing color with exceptional UV and chemical resistance. Available in hundreds of RAL colors.
Best For
Outdoor parts Consumer products Color branding UV exposure
Matte
Vibratory Tumbling
Mass finishing in vibratory media smooths rough edges, removes sintering powder, and produces a consistent matte surface. Reduces Ra without altering dimensions.
Best For
General purpose Clean presentation Pre-coating prep High volume
Metallic
Shot Peening
High-velocity steel shot creates compressive stress on the surface, dramatically increasing fatigue strength. Produces a uniform, metallic-looking satin finish.
Best For
Structural parts Fatigue resistance Automotive Aerospace
Premium
Vapor Smoothing
Solvent vapor reflows the surface layer at a microscopic level, eliminating layer lines and producing a near-injection-molded finish. Waterproof and watertight.
Best For
Medical devices Consumer products Watertight seals Display models
Military
Cerakote
Polymer-ceramic coating originally developed for firearms. Exceptional corrosion, chemical, and abrasion resistance. Thin-film application (0.001") maintains tight tolerances.
Best For
Defense Harsh environments Corrosion resistance Precision parts
Deep Color
Dyeing
Immersive dye penetrates deeply into the PA12 material — not just the surface. Results in rich, consistent color throughout the part. Black is standard; custom colors available.
Best For
Black parts (standard) Color uniformity Consumer goods Low-cost color
Fastest
Raw Grey
Straight from the printer. De-powdered and bead-blasted for clean presentation. The fastest turnaround option — ideal for internal testing, functional prototypes, and R&D.
Best For
Functional testing R&D iterations Internal use Fastest delivery
