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.
VACUUM CASTSmall-batch parts, without the mold cost
Vacuum casting reproduces a master pattern into 20–100+ polyurethane copies per silicone mold. It is the cost-effective bridge between a one-off prototype and full injection molding — ideal for pilot runs and pre-production.
| Batch | 20–100+ per mold |
|---|---|
| Material | PU, ABS-like, PP-like, rubber-like |
| Finish | production-grade, painted |
| Lead time | 5–10 days |
Castable materials
ABS-like and PC-like rigid resins, PP-like flexible resins, rubber-like elastomers, and clear casting resins. Parts can be color-matched and painted to production standards.
Where vacuum casting fits
Pilot runs
20–100 units before molding.
Spare parts
Low-demand replacement batches.
Consumer goods
Soft-touch and clear enclosures.
Medical
Limited batches of device housings.
Automotive
Interior trim pilot sets.
Pre-launch
Market-test inventory.
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
Typically 20–100+ depending on geometry and material.
Yes for low volumes — no steel tooling, so setup cost is a fraction.
Rigid ABS/PC-like, flexible PP/rubber-like and clear resins.
Once volume justifies steel tooling (usually 1,000+ units). We can advise on the crossover.
