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.
SLS · NYLONStrong, functional prototypes
SLS produces strong nylon parts with no support structures, so even complex internal features print cleanly. Perfect for snap-fits, brackets and end-use components that must survive real use.
| Accuracy | ±0.2 mm |
|---|---|
| Materials | PA12, PA11, TPU |
| Lead time | 2–4 days |
| Supports | none required |
Nylon and elastomer powders
PA12 for general strong parts, PA11 for ductile and impact-resistant components, and TPU for flexible, rubber-like parts. SLS parts can be dyed, coated or lightly finished.
Functional SLS parts
Snap-fits
Living hinges and clips that flex.
Brackets
Lightweight structural mounts.
End-use
Low-volume production components.
Ducting
Complex internal channels.
Wearables
Flexible TPU straps and shells.
Jigs & fixtures
Factory tooling that lasts.
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
Yes for functional use — nylon is tougher and isotropic, with no brittle cured-resin layer.
PA12, PA11 and TPU, plus glass- or aluminium-filled variants on request.
No. Unused powder supports the part, enabling complex geometry.
Yes. Many SLS parts go straight into low-volume production.
