Industrial Background
Built on Uniontech's industrial foundation.
Uniontech operates its own equipment R&D, material science, and process engineering teams. That industrial foundation sits behind every Unionfab order.
Why Unionfab
From prototype to low-volume production.
3D printing, precision CNC, and software-driven execution on one manufacturing platform. Quoting, engineering review, factory production, and shipment stay in one controlled system.
Welcome to Unionfab!
Unionfab's Scale, Quality, and Delivery Discipline
Large manufacturing base. Global shipping reach. Digital production control. The precision focus builds on an operational foundation that already operates at scale.

Why Customers Choose Unionfab
Why Choose Unionfab for Low-Volume Manufacturing
Customers choose Unionfab when they need engineering flexibility, production-quality execution, and a stable path from prototype to recurring supply.
Two core technologies, one platform
3D printing for geometry complexity. CNC machining for tight-tolerance features. Both available within the same order flow, without restarting engineering review.
Production-quality parts in low volumes
Parts are produced to stable dimensional standards whether the requirement is five parts, fifty parts, or recurring low-volume supply.
Own factories and controlled execution
Unionfab operates its own facilities and equipment. The same manufacturing system manages production, inspection, and shipment.
Need a faster path to a production-ready part?

Company Foundation
Industrial Manufacturing Services Behind Every Order
Unionfab combines digital speed with a deeper manufacturing base in equipment, materials, process engineering, and production control.
Mission
Make manufacturing easier to execute.
Fast quoting, broad process coverage, stable quality control, and global delivery are organized to remove friction from product development and low-volume production sourcing.
Digital Manufacturing
AI-Powered Quoting and DFM Review
From quote to delivery, every step has software behind it. Faster decisions, fewer suppliers, one connected process.
AI-Powered Instant Quote
Upload files and get pricing fast, with process-aware logic built into the first response.
AI-Assisted DFM Review
Manufacturability checks surface early so geometry, tolerance, and process risk are addressed before production time is committed.
Smart Manufacturing Process Selection
3D printing, CNC machining, or a mixed path can be selected against feature requirements instead of defaulting to a single shop capability.
Integrated Manufacturing Scheduling
ERP, MES, and APS keep demand, machine allocation, inspection, and shipment aligned inside one operating system.
3D Printing and CNC Machining in One Platform
Industrial additive manufacturing and precision machining are both offered as independent services. Each can support a program on its own, or both can be combined when the part requires it.
Industrial 3D Printing
Multiple additive processes matched to geometry, material requirement, and production intent.

Precision CNC Machining
3-axis and 5-axis CNC machining for metals and engineering plastics, held to production-quality tolerances.

How to Work with Us
Many precision programs touch more than one process. Running 3D printing and CNC through separate suppliers means repeated engineering reviews, split quality accountability, and fragmented documentation. Unionfab manages both in one controlled flow.
1
File review and DFM
Geometry assessed, tolerance requirements reviewed, and the right process recommended per feature before production starts.
2
Manufacturing
3D printing, CNC machining, or both in sequence, managed as one program instead of separate vendor tracks.
3
Quality inspection
CMM measurement and dimensional verification, plus surface and visual checks where required.
4
Shipment with documentation
Digital quality report included with every shipment, supported by international carrier coverage and export documentation.
One Manufacturing Workflow. No Supplier Coordination Overhead.
Traditional sourcing often fragments engineering review, production responsibility, and quality records across vendors. Unionfab keeps the full program in one manufacturing workflow.
| Decision Point | Traditional Sourcing | Unionfab |
|---|---|---|
| Engineering review | Repeated across different suppliers | One DFM path across 3D printing and CNC |
| Quality accountability | Split between process vendors | One quality team, one inspection record |
| Process transition | Separate RFQs, handoffs, and follow-up cycles | Managed as one controlled manufacturing program |
| Documentation | Files and reports collected from multiple sources | Consolidated reporting with each shipment |
| Program ownership | Your team coordinates the chain | One owner from quote to delivery |

"Quick, efficient and high quality results. The company produced the correct materials in a high quality-precision manufactured and in a large quantity with amazing consistency. Above those facts, they provided timely updates and communicated along the way. We will use Unionfab in the future and recommend them to other companies too!"

"Trustworthy. The price of my 3d print was very competitive. Arrived about 10 days after submitting the 3d file (from China). The prints were high detail resin, and I'm very satisfied with the quality. Will definitely have them print more in the near future. Sent via UPS with tracking."

"Unionfab is great! I use Unionfab's 3D printing services to create metal sculptures that aren't otherwise possible. They always give feedback to make sure the design is optimized for printing, and their website keeps a great timeline of my projects from start to finish. They're very communicative, prices are reasonable even for metal printing services."
