Velo3D is a technology company that provides the industry’s most advanced fully integrated metal 3D printing solution for mission-critical parts.
Some of the most pioneering companies, including SpaceX, Honeywell, and Lam Research, use the Velo3D solution to drive defense innovation, improve aerospace applications, enhance transportation efficiency, and produce critical oil & gas applications.
While conventional 3D printing and traditional manufacturing methods impose strict design and performance limitations, Velo3D supports true design freedom and allows engineers to build the complex parts they need without compromising performance or quality for manufacturability. In our quest to support tomorrow’s innovations, we enable parts to be printed to exact standards of consistency, quality, and repeatability.
Velo3D has been named to Fast Company’s prestigious annual list of the World’s Most Innovative Companies for 2023. For more information, please visit, or follow the company on LinkedIn or Twitter.
The Team
Join our team of engineers responsible for writing cross-platform C++ tools that handle the preparation of 3D printing jobs. Our printers have created parts that have gone into space and supported the development of super-sonic flight among other application areas.
The tools we develop:
- handle import of 3D CAD and mesh models, converting them to water-tight high-quality surface meshes.
- arrange the models, modify them, and analyze them for issues that might impact the print.
- generate print instructions by mapping a wide range of different process types onto features of the geometry. These highly parallel computations run on clusters or on in the cloud and can take multiple hours. They must be extremely reliable, as a single wrong laser instruction can cause a build to fail.
- schedule the lasing instructions to utilize the available lasers as efficiently as possible.
- enable analyzing and visualizing the resulting gigabytes of data to detect potential issues and support the development of new processes.
We have a modern, cross-platform development setup with thorough CI, benchmarks, static analyzers, clang sanitizers, etc.
