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 controlled parameters eliminate the need to develop new part-specific parameters sets—saving months of development time and reducing the need for specialized technicians.

Watch a short overview of Flow below and download the product brief for more details. 

Native CAD Support for a Simpler Workflow

With Flow, you can easily import native CAD models without converting them to labor-intensive STL mesh file formats. This creates greater process control and leads to more consistent outcomes. Flow also enables easy manipulation of the part file to support, orient, layout, and add labels and serial numbers to the part.

Controlled Parameters for Consistent Properties

With its preloaded controlled parameter sets, Flow enables users to accurately print many of the most aggressive engineering designs without the need for feature-based parameter development. Flow provides greater control and helps users achieve their target material properties by assigning different core instructions to parts within the same build.

Faster Processing for Multi-Part Prints

Flow enables a faster method to calculate build times for builds of different part quantity. After a part has been prepared for print, users can vary the quantity of that part and see updated build times
to better understand the economics of scaled production.

Create a Velo3D “Golden” Print File

Leverage a digital inventory where qualified parts have a persistent, unmodifiable, secure, digital print file (or “Golden” print file) that can be transmitted to a Velo3D-enabled global print facility and recreated to match original specifications.


No matter how you slice it, Flow’s Inspector gives you a deep understanding of the process before a print starts. This provides a powerful tool to review laser sequencing and parameter assignment. See exactly how Flow’s parameter sets are being applied to your part with detailed information on parameters and laser sequencing.

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.

Pre-print Calibrations

Assure displays Sapphire’s automated calibration results that ensure consistent geometric accuracy, surface finish, and validated material properties year-toyear and system-to-system. These in-situ calibrations can be run directly by the user from the printer control screen with no added equipment in a runtime environment. Results of these routines are displayed on Assure and archived for the life of the system for future reference. The main checks composing the Tool Health Checklist (THCL) include: powder bed qualification, focus calibration, laser alignment, thermal sensor alignment, and beam stability.

Multi-Laser Alignment

Pre-build, in-situ alignment ensures high quality overlay between lasers. This fully automated calibration routine runs without additional equipment and validates alignment at multiple locations on the build plate. Additional run-time checks quickly validate alignment every layer making on the fly adjustments if necessary. This improves surface finish by removing part stitch lines and helps to eliminate overlay porosity due to mismatch.

Process Monitoring

During the process, Assure tracks a layer-by-layer validation of atmosphere, consumables, and powder bed health to enable part quality. Throughout the print, factors like oxygen and humidity are tracked to verify that material properties stay consistent. By monitoring consumable indicators, like filter life and powder levels, Assure helps to prevent unexpected interrupts. Lastly, the system continually monitors for part protrusions that can occur due to excessive stress or build set up issues.

Height Mapper

Provides a detailed, layer-by-layer view of powder bed quality and lasing behavior. Height Mapper is a 3D structured light scanner that reveals powder bed topography and ensures a conformal powder bed prior to and after each layer. A very powerful tool for troubleshooting a build, this process checks for target layer thickness, smoothness, and part protrusions.

Integration with Grafana

We have incorporated Grafana visualization application for customized views of the factory and printer status. With Grafana, operators can now access custom powerful analysis tools for deeper understanding of the entire process.

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.

This is attributable to the formation of a tightly adherent Al2O3-type protective oxide scale. This oxide scale also makes Haynes 214 ideal for use in high temperature oxygen environments found in some rocket engines in the pre-burner and main combustion sections.
