Why a 3D printing factory, not a trader
Jinghui 3D is a Shenzhen-based 3D printing and prototyping factory, not a trading company and not a 3D-printer equipment seller. We run our own workshop with SLA, SLS, FDM, CNC machining, vacuum casting and in-house finishing under one roof. What we make for you is custom printed parts, prototypes and low-volume production runs — we do not sell 3D printers or resell hardware. You deal directly with the people who operate the machines.
CUSTOM PARTSYour file, our factory
As a custom 3D printed parts supplier we work make-to-print: you specify geometry, material and tolerance, and our factory delivers consistent parts order after order. Ideal for teams without in-house additive capacity.
| Input | STEP / IGES / STL |
|---|---|
| Tolerance | ±0.1 mm achievable |
| Repeatability | batch-to-batch control |
| Shipping | worldwide express / DDP |
Material selection support
Not sure which resin or nylon fits? We help match material to function — stiffness, temperature, clarity, flexibility — and document the spec so reorders are identical.

From file to finished parts in days
- Send files & requirements. STEP / IGES / STL, target material, quantity and tolerance.
- DFM review. We flag thin walls, support needs, draft angles and tolerance risks before we print.
- Quote in 24 hours. Clear process recommendation and honest lead time — no middleman markup.
- Build in-house. Printed, CNC-machined or vacuum-cast in our own factory.
- Finishing. Cleaning, sanding, painting, electroplating, transparent polish and assembly.
- QC & ship. Dimensional check to ±0.1 mm, photos provided, worldwide express / DDP.
Why buy from a 3D printing factory
Factory-direct pricing
No trading-company markup. You pay for machine time and material, not a reseller's margin.
One integrated workshop
SLA, SLS, FDM, CNC, vacuum casting and finishing in one building — fewer handoffs, tighter quality.
Fast iteration
24-hour quotes and 1–4 day lead times let your engineering team move quickly.
IP protection
NDA on request, file handling under confidentiality, no drawings shared with third parties.
Note: Jinghui 3D is a manufacturing factory. We make custom parts and prototypes for you — we do not sell 3D printers or resell equipment.
