- What do you need to quote additive manufacturing parts?
- CAD (STEP preferred), drawings for CTQ dimensions, quantity, target material/process if known, cosmetic expectations, and any requirements for finishing (dye, bead blast, machining). If loads matter, share load direction and environment.
- Which 3D printing process should I choose?
- At PREMSA we print in FDM: PLA for low-cost prototypes, PETG, ASA, or ABS for functional parts, fiber-filled nylon for more stiffness, and TPU for flexible parts. If your part needs metal or tight tolerances, we recommend CNC machining.
- How do tolerances work in 3D printing?
- Tolerances depend on process, part size, orientation, and finishing. For tight fits, we recommend machining datums and critical interfaces or designing with allowances for post-processing. Use our ISO 2768 chart and tap drill calculator when specifying mating features.
- Can you do production runs with 3D printing?
- Yes. FDM works for production runs when tooling isn't justified. Repeatability improves when you define finishing and inspection criteria up front.
- What about surface finish and cosmetics?
- Surface appearance depends on process and orientation. We can recommend bead blasting, dyeing, sanding, coating, or other finishing to meet cosmetic targets—define A/B/C surfaces and acceptance criteria.
- Do you support threads and assembly features?
- Yes. Depending on material and load, we can tap threads, add inserts, or machine critical holes/fits. Tell us what matters most (strength, repeatability, ease of assembly).
- Can you inspect parts and provide reports?
- Yes. We provide first-article reports and ongoing sampling based on what your part needs. Include your reporting requirements and critical dimensions when you request a quote.
