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 · NYLONPrototype faster, iterate smarter
Prototyping is where speed wins. We return a quote within 24 hours and most prototypes ship in 1–4 days. Because printing, machining and finishing share one building, we can switch process between iterations without juggling vendors.
| Process | SLA / SLS / FDM / CNC |
|---|---|
| Quote | within 24 hours |
| Lead time | 1–4 days |
| DFM | included, free feedback |
| Finishing | paint, plate, polish, assemble |
Pick the right prototype process
SLA gives smooth, detailed visual models; SLS delivers strong nylon functional parts; FDM suits large or rugged components; CNC is best when isotropy and tight tolerance matter. We recommend the process per part, not per machine.
Prototype applications
Design validation
Fit, form and ergonomics checks before tooling.
Functional testing
Snap-fits, brackets, enclosures under load.
Trade-show models
Painted and plated display prototypes.
Bridge tooling
Pre-injection prototypes from silicone molds.
User research
Hand-feel models for focus groups.
Pre-production
Pilot runs ahead of mass manufacturing.
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
Quotes in 24 hours; most prototypes ship in 1–4 days depending on size, process and finishing.
Yes. DFM feedback is included — we flag thin walls, support needs and tolerance risks up front.
Absolutely. Fast lead times are built for iteration; many customers run several revisions per week.
Cleaning and basic finishing are standard; painting, electroplating and assembly are available in-house.
