A Fully Integrated Metal AM Solution Unlike Any Other

Velo3D has developed a fully integrated manufacturing solution comprised of software, hardware, & an intelligent underlying manufacturing process allowing engineers to build mission-critical parts.

Fully Integrated Software and Hardware Solution for Unprecedented, Production-Ready Results

The Velo3D metal AM solution unlocks design freedom for innovative parts. It consists of Flow print preparation software, the Sapphire family of metal 3D printers, Assure real-time quality validation and control software, and is enabled by our Intelligent Fusion underlying manufacturing process.

Flow Software

Flow print preparation software is responsible for prescribing the manufacturing process for the Sapphire family of metal 3D printers. The software’s feature-based process library eliminates the need to develop new part-specific parameters sets—saving months of development time and reducing the need for specialized technicians.

Native CAD Support for Simpler Workflows

Flow lets you easily import native CAD models without converting them to labor-intensive STL mesh file formats. This creates greater process control and reduces the variability between operators, leading to more consistent outcomes.

Library of Feature-Based Processes

Flow makes it simple to print advanced geometries and achieve validated material properties for parts by pulling from an optimized library of feature-based recipes and automatically applying them as needed.

Intelligent Slicing

Once a layout is complete, Flow intelligently analyzes the plan and prepares the part for print. Flow provides a powerful tool to review laser sequencing and recipe assignment, which helps eliminate possible anomalies and diagnose post-build issues.

Create a Golden Print File

Flow enables unprecedented scalability and repeatability. The Golden Print File can be used to manufacture identical parts from any Sapphire in the world with consistent material properties, geometric accuracy, and feature resolution.

Sapphire Printers

State-of-the-Art 3D Metal Printers

Our next-generation Velo3D Sapphire family of printers all use the same software, run the same process, and use the same materials ensuring repeatable consistency across the fleet. Engineered to meet your design, performance, and quality requirements, our printers continually monitor and control the build layer-by-layer for predicable and efficient production. The outcome results in complex part geometries for real-world applications.

Unlike conventional AM printers, the Sapphire printers utilize a proprietary protrusion tolerant non-contact recoater that almost eliminates the risk of part collisions, dramatically improving yields and facilitating a printing process enabling lower angles and overhangs down to zero degrees, thin leak tight walls, large diameter and extremely small inner tubes, with little or no supports.

Assure Software

Quality assurance is essential, and it’s never been easier.

Velo3D Assure Quality Validation Software
Velo3D Assure Quality Validation Software

Part Quality

In real time, Assure software provides instant visibility into every layer of the build through real-time sensors, physics-based excursion detection algorithms, and optical measurements. These in-situ monitoring systems and reports give engineers confidence that the printer is operating at optimal performance and the resulting part is of the highest quality. Assure also provides a detailed build report showing each layer. This quality control system accelerates the move to production by verifying part-to-part consistency to enable scalability.

Print Quality

Assure™ tracks and reports the Sapphire pre flight check prior to each build. Together, these checks validate that the Sapphire printers are ready to print and that they stay within specification during a build.


Each build includes a detailed build report that contains part quality data and printer health results, making it easier to qualify parts to move AM into production.

Intelligent Fusion
Underlying Manufacturing Process

Intelligent Fusion is the underlying manufacturing process that binds and facilitates all aspects of the Velo3D manufacturing solution, which includes print preparation software (Flow), advanced metal printer (Sapphire), and quality assurance software (Assure).

Design Freedom

Intelligent Fusion is the catalyst to the unique printing capabilities of the fully integrated metal AM solution. Specialized processes (recipes) were designed to minimize thermo-mechanical distortions and ensure high-quality surfaces at build angles as low as zero degrees. It is built into all Sapphire printers.

Geometry-Based Detection

Intelligent Fusion is the key enabler for printing lower angles, thinner walls, and high aspect ratios. This process control is so precise, the need to design-in support structures is greatly reduced and often eliminated.

Highly intelligent and sophisticated software uses geometric feature detection to apply the optimal physical processes to the appropriate features. To be able to do that, each geometric model is decomposed into various distinct geometric features and the appropriate optimal process is then applied automatically.

Additionally, the geometric feature detection algorithms use information from multiple layers, leveraging information from previous layers to define the print strategy for the next layer.

Monitoring the Build Process

To achieve consistent material properties across a printed part and reduce print variability from build-to-build, the Velo3D system ensures that every relevant build parameter is monitored throughout the build process.

Natural process instabilities caused by minute hardware and powder variations can cause the process to drift outside the acceptable range, thereby affecting the final part outcome. To achieve consistent material properties across a printed part and reduce print variability from build to build, the Velo3D system ensures that every relevant build parameter is monitored throughout the build process.
