With nearly 800 systems (and growing), ranging from over 500 SLA machines from UnionTech to Stratasys, BLT and even HP for metal binder jetting.
Unionfab, a global leader in industrial additive manufacturing, has officially positioned itself as the world’s largest production-based 3D printing service by number of machines. This is a known fact in the industry but the sheer size of the company may not be immediately clear: With nearly 800 industrial 3D printers (and counting) installed across its production sites, UnionFab surpasses every competitor in both machine count and technological diversity.
Let’s explore the scope of their operations, the incredible scale of their printer factory, and how this company is literally reshaping global AM (imagine if all those SLA systems had come from 3D Systems…).
Total 3D printers at UnionFab: A breakdown by technology
UnionFab’s unmatched printer fleet covers a comprehensive range of 3D printing technologies, including SLA, SLS, SLM, FDM, MJF, PolyJet, DLP, and even metal Binder Jetting (from both ExOne and HP, but not yet from EASYMFG). Each printer is optimized for specific production needs—from small, highly detailed parts to massive, functional components. UnionFab houses over 727 production-ready 3D printers. Their SLA fleet alone comprises over 540 UnionTech machines, a number that dwarfs many competitors’ entire inventories.
