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 · RAWSmooth, detailed resin parts
SLA is our go-to for visual models, enclosures and master patterns. The surface finish is excellent and ideal for post-processing such as electroplating and hand painting.
| Accuracy | ±0.1 mm |
|---|---|
| Materials | Standard / tough / clear / high-temp resin |
| Lead time | 1–3 days |
| Max detail | fine features, smooth walls |
Resin options
Standard resin for general models, tough resin for snap-fits, clear resin for lenses and transparent shells, and high-temp resin for heat-resistant parts. All can be painted, plated or polished in-house.
Where SLA shines
Enclosures
Smooth-wall housings for electronics.
Master patterns
Patterns for vacuum casting and molding.
Display models
Hand-painted, show-ready pieces.
Jewelry & art
Fine detail and organic shapes.
Clear parts
Lenses, light pipes, transparent shells.
High-temp
Heat-resistant fixtures and tools.
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
Around ±0.1 mm, suitable for fit and detail-critical parts.
Yes — clear resin plus polishing gives optically clear results for lenses and shells.
Yes, both are done in-house, including chrome, nickel and gold-look electroplating.
Standard resin is best for visual and moderate-use parts; choose tough resin for snap-fits and light function.
