FAQ

Frequently Asked Questions

Common questions about our rapid prototyping and manufacturing services

We accept STEP (.stp), IGES, X_T (Parasolid), SLDPRT, STL, OBJ for 3D models, and PDF or DWG for 2D drawings. STEP format is preferred for CNC machining quotes as it contains the most complete geometry data. Please include project details such as expected quantities, required materials, surface finishes, and any critical tolerances.

Our 3D printing service can deliver prototypes in as fast as 24 hours for standard geometries. CNC machined parts typically ship within 3–7 business days, depending on complexity, material, and surface finish requirements. Rush orders are available — contact us for expedited timelines.

We machine 30+ engineering-grade plastics including ABS, PC, PMMA (Acrylic), POM (Delrin), Nylon, PP, PEEK, and PEI. For metals, we work with aluminum (6061, 7075), stainless steel (304, 316), brass, copper, titanium, tool steel, and more. Visit our materials page for the full list.

Yes — we handle finishing in-house for faster turnaround. Options include anodizing (Type II & III), powder coating, bead blasting, polishing, brushing, plating (zinc, nickel, chrome), painting, silk screening, pad printing, laser engraving, and electropolishing. Custom color matching with Pantone numbers is available.

CNC machining is best when you need tight tolerances, production-grade materials, and excellent surface finish. 3D printing is ideal for complex geometries, fast turnaround (24h), and early-stage design validation where material properties are less critical. For parts that need both speed and strength, we can advise the best approach — contact us with your project details.

KUSLA is ISO 9001:2015 certified. We support First Article Inspection (FAI), PPAP documentation, CMM measurement reports, and material certifications upon request. Our quality control process includes in-process inspection, final inspection, and full dimensional reports for critical parts.
