Rapid Prototyping Services FAQs

  • Q1: What is rapid prototyping and how does it work?

    A:Rapid prototyping is the design of sample parts that are produced quickly in order to confirm the design, functionality, and maneuverability. Prototyping like CNC machining, sheet metal fabrication, plastic molding and EDM have allowed us to convert your CAD files to real parts in days.

  • Q2: What software is used for rapid prototyping?

    A: In CNC rapid prototyping, the main software includes CAD software (such as SolidWorks, AutoCAD, CATIA, Fusion 360) for creating 3D models, and CAM software (such as Mastercam, Powermill, SolidCAM, Fusion 360 CAM) for generating precise toolpaths. In some cases, simulation and analysis tools like ANSYS or COMSOL are also applied to verify design performance before machining. By combining CAD and CAM, we ensure that every prototype is produced with high accuracy, efficiency, and consistency.

  • Q3: How fast can I receive my prototype?

    Q3: How fast can I receive my prototype? A: Lead times depend on part complexity, but in general rapid prototyping and small batch customization take 7–15 days. Simple prototypes or urgent projects can be delivered in as little as 5–7 days. We prioritize fast response and flexible scheduling to ensure quick turnaround and keep your project on track.

  • Q4: Is there a minimum order quantity for prototyping?

    A: No. We fully support low-volume production and one-off prototyping. Our minimum order quantity is just 1 piece, perfect for design validation and small-batch testing.

  • Q5: Can you provide finishing options for prototypes?

    Q5: Can you provide finishing options for prototypes? A: Yes. We offer polishing, sandblasting, anodizing, plating, and other finishing services so your prototypes not only function correctly but also look ready for presentation or end-use testing.

  • Q6: Do you offer inspection reports for prototype parts?

    A: Absolutely. Upon request, we can provide free material certificates and quality inspection reports to ensure your prototypes meet the required specifications.
