BigRep adds desktop-style usability upgrades to its ONE.5X large-format 3D printer

BigRep has introduced a series of usability upgrades to its ONE.5X large-format 3D printer, bringing desktop-style convenience to the industrial polymer FFF segment. The enhancements include a fully enclosed build chamber with active heating, a new touchscreen interface with simplified workflow navigation, and an automated bed-leveling system that eliminates manual calibration. The ONE.5X retains its 1000 x 800 x 600 mm build volume and supports engineering-grade thermoplastics such as PA6/66, PETG, and ASA, targeting tooling, jigs, and low-volume production applications. The upgrades are available as a retrofit kit for existing ONE.5X units and come standard on new shipments from BigRep's Berlin headquarters.

This update matters because it addresses a persistent friction point in large-format polymer AM: the gap between industrial build volumes and the ease-of-use expectations set by desktop FFF machines. While the ONE.5X competes with systems from Caracol, CMS, and Thermwood in the large-format additive manufacturing (LFAM) space, BigRep is betting that workflow simplification - not just build envelope size - will drive adoption in industrial tooling and short-run production. The enclosed heated chamber reduces warping in semi-crystalline materials, a common failure mode that has limited LFAM adoption outside of prototyping. By lowering the operator skill requirement, BigRep positions the ONE.5X as a bridge between desktop polymer extrusion and production-ready LFAM, a segment that remains fragmented and service-bureau dominated.

For users evaluating large-format FFF, the practical takeaway is that the ONE.5X now competes more directly with mid-range industrial systems on reliability while retaining its price advantage. BigRep must now demonstrate that the retrofit program and new units deliver consistent first-layer adhesion and dimensional stability across multiple material types, not just in controlled demo conditions. Buyers should request test prints with their specific materials and assess whether the automated bed leveling and chamber heating meaningfully reduce scrap rates in their own workflows.
