Precision Rapid Prototyping Services
High-Precision CNC Machining & Additive Manufacturing for Functional Prototypes
ISO 14001:2015 ISO 9001:2015 IATF 16949:2016
Prototype Service Overview
We provide end‑to‑end rapid prototyping solutions to validate functionality, de‑risk production and accelerate time‑to‑market. Our production‑intent prototypes use CNC machining, additive manufacturing, sheet metal fabrication and rapid molding to deliver high‑precision parts with full dimensional certification and engineering support.
The precision of their prototypes is exceptional. We needed a complex multi-part assembly to test fit and function, and every component came together perfectly. This tangible validation saved us from a costly tooling mistake and gave our design team the confidence to move forward. An invaluable step in our development process.

FAQs About Rapid Prototyping Services
What types of prototyping do you offer?
expand_less expand_moreWe offer a comprehensive range of prototyping services, including:· 3D Printing (Rapid Prototyping): SLA, SLS, FDM, and PolyJet for concept models and functional parts. · CNC Machining: For high-precision, durable prototypes in metals and engineering plastics.
· Sheet Metal Prototyping: For enclosures, brackets, and chassis. · Injection Molding (Low-Volume): Using soft tools or rapid tooling for small batches of production-like parts.
What is your typical turnaround time?
expand_less expand_moreTurnaround time depends on the complexity, technology, and quantity. A general guideline is: · Simple 3D Printed Models: 2-5 business days. · CNC Machined Parts: 5-10 business days. · Low-Volume Injection Molding: 2-4 weeks. We always provide a project-specific timeline and quote after reviewing your design files. Rush services are available for most projects.
Can you help with design for manufacturability (DFM) feedback?
expand_less expand_moreAbsolutely. Our engineering team provides complimentary basic DFM analysis with every quote. We will review your design and suggest modifications to improve functionality, reduce cost, and ensure it is optimized for the chosen prototyping or eventual production process.
Do you offer assembly and finishing services?
expand_less expand_moreYes, we provide full post-processing and value-added services, including: · Finishing: Sanding, priming, painting, texturing, plating. · Assembly: Gluing, fastening, inserting hardware, wiring. · Decoration: Silk-screening, pad printing, labeling. Please specify your requirements in your quote request.
How do I get started?
expand_less expand_moreGetting started is simple:
1. Prepare your 3D CAD files and project requirements.
2. Submit a request for quote (RFQ) through our website or contact us via email.
3. Consult with our engineering team to finalize specifications.
4. Approve the quote and timeline, and we’ll begin production.
Can your prototypes be used for functional testing or as end-use parts?
expand_less expand_moreYes, many of our prototypes are fully functional. We will recommend the best technology and material (e.g., engineering-grade resins, metals) based on your testing requirements—whether it’s for thermal, mechanical, fluidic, or electrical validation. Some high-performance prototypes can even serve as end-use parts in low-volume applications.
