What Unionfab does
Unionfab is a China-based digital manufacturing platform that provides on-demand 3D printing, CNC machining, casting, and injection molding services to engineering and procurement teams globally. The company operates 10 proprietary smart factories with 1,000+ industrial 3D printers and 400+ precision CNC cells, supplemented by a 300+ certified partner network, producing 2M+ parts per year for 80,000+ customers across 170+ countries. Its headquarters are in Shanghai (R&D and 3D printing hub, established 2000) and Shenzhen (CNC fleet, established 2021).
The platform is built on self-developed ERP, MES, and APS systems that orchestrate multi-process manufacturing under one digital workflow, with the Polykits™ AI Engine providing instant CAD-to-quote pricing and automated Design for Manufacturing (DFM) feedback. Unionfab supports 100+ additive materials and 60+ CNC alloys, with CNC tolerances up to ±0.0005 inches (±0.0127mm), large-scale SLA printing up to 2100x700x800mm, and lead times of 1-5 days for CNC. The company holds ISO 9001, ISO 14001, ISO 13485, ISO 27001, IATF 16949, and AS9100D certifications, enabling it to serve regulated verticals including automotive, medical, and aerospace.
Revenue is generated primarily through usage-based pricing: 3D printing is priced on material weight (e.g., Nylon PA12 at $0.25/gram), while CNC machining is priced on hourly machine rates ($40-120/hr depending on axis count), with add-on fees for finishing, packaging, and shipping. The company employs a hybrid go-to-market combining a product-led growth self-serve platform (instant quote, CAD upload, 24/7 ordering) with sales-assisted enterprise support via WhatsApp and email. Named customers include Tesla, Siemens, DJI, Evonik, BASF, and Schneider Electric across automotive, industrial, robotics, and chemicals verticals.
