Why engineers choose us
Most buyers who come to us have already been burned by a supplier. Here is what they tell us — and how our China 3D printing service fixes it.
As a direct China factory (not a middleman or broker), we control the whole process — from quoting to printing, post-processing, inspection, and shipping. That means:
Our technologies
Different parts need different processes. Our China factory runs all six major 3D printing technologies side by side, so we can pick the right one for your job — instead of forcing every part into one machine.
Low-cost, tough plastic parts extruded layer by layer. Best for quick form-and-fit prototypes, jigs, fixtures, and large enclosures.
UV-cured resin printed with a laser. Delivers smooth surfaces, fine detail, and tight tolerances — perfect for visual models, master patterns, and small detailed parts.
Similar to SLA but cures an entire layer at once with a projector. Faster for small, high-detail parts like jewelry masters, dental models, and micro-components.
A laser sinters nylon powder into strong, functional parts without support structures. Great for hinges, snap fits, ductwork, and low-volume production.
HP's industrial nylon process — faster and more consistent than SLS for production runs. Produces near-isotropic parts with excellent surface finish and repeatability.
Laser-melted metal powder for fully dense metal parts. Used for aerospace, medical, and tooling applications where strength, weight, and complex geometry matter.
Materials
Whether you need a cheap prototype, a tough functional part, or a production-grade metal component, we keep the material on our shelves. Do not see what you need? Ask our engineers — we can source it.
Capabilities
Real numbers so you can spec your part with confidence. Have a part outside these specs? Send it over — we often can do it.

Industries we serve
From one-off concept models to certified production parts, our China 3D printing factory ships to buyers in aerospace, medical, automotive, consumer products, and more.
Finishing options
Printing is only half the job. We offer a full range of post-processing so your parts arrive looking like finished products, not raw prints.
Why choose us
We are not a broker or a trading company. We are the people running the machines.
No middlemen, no markup. You deal directly with the manufacturer. Most customers save 30–50% compared to US and EU 3D printing services.
Your file is reviewed by a manufacturing engineer, not a salesperson. You get free DFM feedback before any money changes hands.
Quote in under 24 hours. Parts in 1–5 days. Rush service available when you need parts tomorrow.
We do more than 3D printing. When your project is ready, move straight to CNC machining, injection molding, urethane casting, or sheet metal — all under one roof.
Every part goes through incoming-material check, in-process inspection, and outgoing QC. CMM reports, material certificates, and first-article inspection on request.
NDAs are standard. We never share customer files, photos, or designs. Your design stays yours.
How it works
Getting 3D printed parts from our China factory could not be easier.
Send us your STL, STEP, STP, IGES, OBJ, or SolidWorks file. Tell us the quantity, material, finish, and when you need it.
We review your file, run a free DFM check, and send a clear, itemized price. No hidden fees.
Your parts are printed in our Dongguan factory, finished, and inspected before they leave the building.
We ship DHL, FedEx, UPS, or by air/sea for larger orders. Tracking number and inspection photos are sent with every order.
Quality you can count on
YiguProto is an ISO 9001-certified China manufacturer. Our 3D printing factory follows documented procedures for quoting, production, inspection, and shipping — so you get the same quality every time you order.
We know that when you order from an overseas supplier, trust matters. Here is what you get on every order:
