Velo3D Sapphire

The Velo3D Sapphire is the system that put Velo3D on the map as a serious contender in metal additive manufacturing. Built around their SupportFree printing technology, the Sapphire enables production of complex metal parts with overhangs down to sub-5 degrees without conventional support structures — a capability that fundamentally changes what is geometrically possible in laser powder bed fusion (LPBF). The standard build envelope of 315 mm diameter x 400 mm height accommodates a wide range of aerospace, energy, and industrial components.

The Sapphire uses two 1 kW fiber lasers scanning simultaneously across the build area, paired with Velo3D's proprietary non-contact recoater technology. Unlike traditional rigid recoater blades that can crash into parts with aggressive overhangs or thin-wall features, the Sapphire's recoater design tolerates part geometries that cause build failures on conventional LPBF systems. This is not marketing hyperbole — shops running Sapphire systems routinely print internal channels, manifolds, and heat exchangers with geometries that are simply not achievable without extensive supports on standard metal printers.

Velo3D's Intelligent Fusion technology is the integrated process control system that monitors and adjusts laser parameters in real time during the build. Combined with the Assure quality management software, operators receive layer-by-layer build data including thermal signatures, deformation metrics, and excursion detection. For aerospace and medical applications where part qualification is non-negotiable, this level of in-process monitoring provides the data package that quality engineers require.

The Sapphire processes qualified materials including Inconel 718, Inconel 625, Ti-6Al-4V, Hastelloy X, aluminum F357, copper, and stainless steels. Build rates depend heavily on geometry and material, but dual 1 kW laser operation provides competitive throughput for the build volume. The Flow print preparation software handles the full workflow from CAD import through orientation, support minimization, slicing, and process parameter assignment. New Sapphire systems are priced between $800,000 and $1,200,000.
