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.
METAL · CLEARSpecialty materials, done in-house
Metal 3D printing builds strong, complex metal parts without tooling; transparent resin with polishing delivers optically clear components. Both are finishing-intensive, so we keep the whole process — print to polish — inside our factory.
| Metal | stainless / aluminum / titanium |
|---|---|
| Clear resin | transparent, post-cured |
| Finish | polish, plate, anodize |
| Lead time | 3–8 days |
Metal and clear options
Metal via DMLS / powder sintering in stainless, aluminum and titanium; transparent parts via clear resin with multi-stage polishing for lens-grade clarity. Metal parts can be machined-post or surface-treated.
Specialty part uses
Heat sinks
Complex metal thermal parts.
Lenses
Clear optical shells.
Medical

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
Stainless steel, aluminum and titanium via powder-bed fusion.
Clear resin plus multi-stage polishing reaches lens-grade transparency.
Metal printed parts are fully dense and strong; post-machining tightens critical dimensions.
Yes — polishing, plating and anodizing are all done in our workshop.
