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.

Price and efficiency

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.

Authentic Customer Reviews

Hunt Dabney

The 4 parts look great and work very well. This order was to solve a problem on some equipment, so only the 4 parts were needed.

We were very pleased with your quality, cost and delivery, and will certainly order from you in the future. I have also recommended you to friends who own other companies.

I couldn’t be happier with this order. The quality is as quoted and the lead time was very not only very fast and it was done on schedule.

The service was absolute world-class. Thanks a lot to Linda Dong from the sales team for the outstanding assistance. Also, the contact with the engineer Laser was top-notch.
