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.
SLA · RAWOne workshop, every process you need
Our factory combines additive and subtractive manufacturing so we can pick the right process for each part: SLA and SLS for complex geometry, FDM for large or functional parts, CNC for tight-tolerance metal and plastic, and vacuum casting for small production runs. All finishing — sanding, painting, electroplating, assembly — happens in-house.
| Technologies | SLA / SLS / FDM / CNC / vacuum casting |
|---|---|
| Accuracy | ±0.1 mm on precision parts |
| Lead time | 1–4 days typical |
| MOQ | 1 piece — no minimum order |
| Business model | OEM / ODM contract manufacturing |
Materials we run every day
Standard and tough resin, clear and high-temp resin, PA12 / PA11 nylon, TPU, ABS-like and PLA-like photopolymers, and a wide range of CNC metals and plastics. Need a specialty material? Ask — we qualify new resins and powders for production.

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.
Frequently asked questions
We are a factory. All parts are produced in our own Shenzhen workshop — no subcontracting of your critical dimensions.
No. Jinghui 3D is a manufacturing service. We make custom parts and prototypes for you; we do not sell or resell 3D printing equipment.
One piece. We support single prototypes and scale up to low-volume production without a tooling commitment.
Yes. We sign NDAs on request and keep customer files internal — they are never shared with third parties.
