3D/Additive/Alternative Software

Campbell, California – VELO3D’s Flow print preparation software ensures predictable print outcomes while its native CAD workflow controls performance consistent with the design intent, significantly reducing print preparation time. Working in concert with VELO3D’s Sapphire system, Flow enables next generation SupportFree additive manufacturing for parts previously not possible.

Flow is specifically designed for Sapphire, VELO3D’s laser fusion metal additive manufacturing system. It includes tools that help with part orientation, support generation, simulated print predictions, per-surface process application, slice composer, and process review. Manufacturers can now print complex part geometries SupportFree, enabling volume manufacturing of parts that are otherwise impossible or uneconomical to print due to hard-to-remove support structures.

Manufacturing any design
VELO3D’s ability to print low angles and overhangs below five degrees, as well as large inner diameters and tubes up to 40mm without the need for supports, eliminates the need for difficult and laborious post-processing cleanup. This capability breaks the limiting boundary of other systems that require supports for most angles below 45°, constraining design freedom and limiting the number of designs that can be produced with additive technology.

Flow key features include:

  • New physics-driven simulation engine is optimized for VELO3D process capabilities and the Sapphire system; contributes to achieving a first print success rate of up to 90%, preventing many failed iterations
  • Powerful simulation utility predicts the print outcome, applying print deformation correction and validating the execution feasibility of the print prior to starting the build process; ensures that the print outcome results in dimensionally accurate design intent
  • Sophisticated composer detects geometric features and applies the optimized, proven print process to specific features, delivering predictable print outcomes

Accelerating print preparation with Flow’s native CAD workflow
The integration of print preparation, simulation, and composing capabilities into a single software eliminates historic incompatibilities, significantly simplifying the workflow. Native CAD workflow enables new user experience with smart selection, refinement, and filtering of part features and reduces hundreds of manual steps to a few clicks. This enables users to focus their efforts on solving problems on the application level instead of troubleshooting machine level parameters.

Best print outcome based on design intent
Flow is the first and only print preparation software that manages print outcome based on the design intent. With the native CAD import, the design intent is preserved, and users can optimize for target cost and quality parameters by surface. It enables selection of areas to optimize the surface finish, and others for throughput. Flow allows the user to optimize a print within the design requirements by delivering the highest possible quality for critical surfaces, while non-critical surfaces can be optimized for throughput.
