China 3D Printing Manufacturer & Supplier
YiguProto is a China-based 3D printing factory and manufacturer. We run industrial-grade machines 24/7 to make plastic and metal parts for product teams, engineers, and companies worldwide.
No hidden fees. No middleman markup. You work directly with our factory team from quote to delivery.
The Problems We Solve
We hear this every day from buyers. That is why we built our China 3D printing factory to fix these issues.
Some suppliers keep you waiting 3+ days just for a price. We quote most jobs the same business day. Upload your files before 3pm China time, get price that evening.
Wrong dimensions. Bad surface finish. Warped parts. We do full inspection on every order. You get inspection reports on request. If we mess up, we reprint for free.
You email 3 times and get no reply. Our sales engineers speak English. You get one dedicated contact for your whole project. No robot answers, no passed-around tickets.
The price you see on the quote is the price you pay. No hidden setup fees. No "material surcharge" added later. We honor our quote for 30 days.
You worry about your product design being copied. All files stay on our secure servers. We sign NDAs before we look at your project. No files leave the factory without permission.
Most shops only do prototypes. We support 1 piece all the way to 100,000+ production parts. Same factory, same quality team, same contact person - whether you need 1 or 10,000.
Our Factory Capabilities
Our 3,200 m² factory in Dongguan, China runs 45+ industrial 3D printers. We cover every major additive manufacturing technology in one location.
Best for low-cost prototypes, jigs, fixtures, and large parts.
Best for high-detail prototypes, smooth surfaces, show models.
Best for functional nylon parts, complex geometries, no supports needed.
Best for production nylon parts, consistent quality, fast for batches.
Best for functional metal parts, lightweight aerospace/automotive components, conformal cooling tools.
Not sure which technology fits your part? Our engineers will recommend the best option for free.
Ask an Engineer Which Process to UseWhy Work With Our China 3D Printing Service
You talk directly to the people making your parts. No middleman taking 20-40% cut. That means lower prices and faster communication for you.
Every project gets a dedicated project engineer who speaks English. We catch design issues before printing starts. We reply within 4 hours during business hours.
We follow documented quality procedures for every order. Material certificates, inspection reports, and CMM measurement available for production runs.
We don't just do 3D printing. If your project later needs CNC machining, injection molding, or assembly, you don't have to find and qualify a new supplier.
We ship DHL, FedEx, UPS worldwide. Typical delivery to US/EU: 3-5 days after production. You get tracking numbers the day parts ship.
Quality Guarantee
Bad parts cost you time and money. We built a 5-step quality check into every job - from the minute you send us files to the day parts ship out.
Engineer checks your STL/STEP files for wall thickness, geometry issues, printability.
We send you free DFM report if we find issues. We suggest fixes to save you cost or improve strength.
We verify material batch before printing. All materials come with traceable lot numbers.
Operators check first part off the printer. We monitor key dimensions during batch runs.
100% visual check before packing. Calipers/CMM for critical dimensions on request.
If parts arrive not matching your drawing or our agreed specifications, we will reprint them at no cost or issue a full refund. No arguments, no delays.
