What Makes Us Extraordinary

RapidDirect shares a continuous growth of 300%+ year-over-year annual growth in rapid prototyping and manufacturing services. These are the features that make us stand out.

Unlike other online rapid prototyping companies who outsource your projects, RapidDirect has its own rapid prototyping factory in Shenzhen, China. This enables up to 30% additional price reduction and more reliable lead-time.

Engineering support

More than making custom parts, we provide value. From early-stage material selection, custom prototyping design advice, to money-saving tips and technical suggestions based on experience for end-use production, we provide professional engineering support on a part-by-part and assembly-by-assembly basis.

Quality assurance

Quality comes first at RapidDirect. As an ISO 9001:2015 certificated prototype manufacturing company, we provide SGS, RoHS, material certifications, and full dimensional report for our customers. First Article Inspection Program is also available on your request.

Getting the quotation online is a mind-blowing experience, and the result turned out to be impressive. It saves me a lot of time and effort communicating. What’s even better is I was still provided a dedicated Sales Engineer for person-to-person communication if necessary.
