3D printing, precision CNC, and software-driven execution on one manufacturing platform. Quoting, engineering review, factory production, and shipment stay in one controlled system.
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
Customers choose Unionfab when they need engineering flexibility, production-quality execution, and a stable path from prototype to recurring supply.
3D printing for geometry complexity. CNC machining for tight-tolerance features. Both available within the same order flow, without restarting engineering review.
Parts are produced to stable dimensional standards whether the requirement is five parts, fifty parts, or recurring low-volume supply.
Unionfab operates its own facilities and equipment. The same manufacturing system manages production, inspection, and shipment.
Uniontech operates its own equipment R&D, material science, and process engineering teams. That industrial foundation sits behind every Unionfab order.
Upload CAD files for DFM review and process recommendation across both 3D printing and CNC.
Digital Manufacturing
From quote to delivery, every step has software behind it. Faster decisions, fewer suppliers, one connected process.
Upload files and get pricing fast, with process-aware logic built into the first response.
Manufacturability checks surface early so geometry, tolerance, and process risk are addressed before production time is committed.
3D printing, CNC machining, or a mixed path can be selected against feature requirements instead of defaulting to a single shop capability.
ERP, MES, and APS keep demand, machine allocation, inspection, and shipment aligned inside one operating system.
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.
Multiple additive processes matched to geometry, material requirement, and production intent.
3-axis and 5-axis CNC machining for metals and engineering plastics, held to production-quality tolerances.
Request an engineering review for feature-level routing across 3D printing, CNC, or combined manufacturing.
From initial project submission to final delivery, UnionFab coordinates every stage through one streamlined workflow. Whether your project requires a single manufacturing process or multiple processes, our team manages quoting, engineering review, production, quality inspection, and global delivery.
Upload your CAD files, technical drawings, or BOM, and specify the required material, quantity, tolerances, surface finish, and quality requirements.
Project submitted confirmation
Standard projects may receive an instant online quote. Complex projects will be reviewed by our engineering team, who will provide a customized quotation, estimated lead time, and DFM recommendations where necessary.
Quotation, lead time & feedback
Review and confirm the manufacturing process, material, tolerances, lead time, inspection requirements, quality documentation, and commercial terms. Complete the payment or submit a purchase order to begin production.
Final specs & order confirmation
Unionfab coordinates single-process or multi-process production through one managed workflow. Progress updates and notifications of any issues requiring your attention are provided throughout the project.
Progress & status updates
Dimensional, visual, and functional inspections are performed according to the agreed quality plan. Applicable quality documentation, secure packaging, shipping arrangements, and tracking information are provided based on the project requirements.

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 |
Large-format printing, metal additive manufacturing, CNC accuracy, and premium finishing extend the platform well beyond standard rapid prototyping.

"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."
"Excellent CNC machining quality and consistency. The parts were manufactured according to our drawings, with accurate dimensions, clean surface finishes, and a very good fit during assembly. UnionFab’s engineering team also reviewed our design and provided practical suggestions before production. We are very satisfied with the results and will continue working with UnionFab on future projects."
"Fast response, competitive pricing, and reliable delivery. UnionFab quickly understood our CNC machining requirements and kept us updated throughout the project. The finished parts arrived well packaged and on schedule, and the quality met our expectations. The entire process, from quotation to delivery, was smooth and professional. We would be happy to recommend UnionFab."
