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 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 underlying manufacturing process.

Flow Software

Flow print preparation software is responsible for prescribing the manufacturing process for the Sapphire printer family.

Watch a short overview of Flow below.

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.

Transfer Your Knowledge and Achieve Scale

Flow enables users to accurately print many of the most aggressive engineering designs without the need for feature-based parameter development. Flow can help users achieve their target material properties by assigning different core instructions to parts within the same build or you can utilize Flow Developer, an optional feature of Flow, which enables engineers to determine the optimal process for their application by unlocking the ability to transfer or create their own parameter sets into Flow. This eliminates the need to restart projects, granting access to Sapphire printers’ control, quality, and repeatability allowing engineers to achieve their program goals.

Flow PanX Integration for First Print Success

Velo3D’s integration with PanOptimization takes the guess work out of metal AM by simulating the thermomechanical behavior of the printed part. Quickly highlight issues related to temperature, stress, and distortion for parts of any printable size.

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.

Flow Developer 

Flow Developer enables engineers to determine the optimal process for their application by unlocking the ability to transfer or create their own parameter sets into Flow. This eliminates the need to restart projects, granting access to Sapphire printers’ control, quality, and repeatability allowing engineers to achieve their program goals. Users now have maximum flexibility, visibility, and control with the power to create, modify, and inspect processes all within one software platform.

Transfer Your Knowledge and Achieve Scale

Improve the business case for your application through productivity optimization. For parts where throughput is the highest priority, leverage the flexibility to use thicker layers in any material and speed up the print time. For parts where higher feature resolution or different material properties are required, customize to achieve the design intent.

Obtain Full Process Transparency

Combined with Assure’s quality control and build report summaries, Flow Developer unlocks the most comprehensive view of the manufacturing process for each application. This enables companies to integrate AM into their engineering and manufacturing processes.

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

Velo3D’s Assure Quality Software offers comprehensive factory monitoring, providing real-time tracking of machine fleet and live build progress status for effective oversight of factory performance. Integrated with Grafana, engineers can customize graphs and dashboards using nearly 1,000 sensor readings, offering detailed insights into the process. Automated system calibrations ensure replication of parts within geometric and material property specifications, with Assure recording printer calibration history to swiftly identify issues and trends. In-process monitoring offers an overview of build performance data, including optical health and powder bed quality, allowing users to delve into specification compliance. Additionally, build history reporting simplifies access to historic records and critical build information, offering on-demand summaries of tool calibration status, interrupt reporting, and height mapper images.

Pre-Print Calibrations

Assure displays Sapphire’s automated calibration results that ensure consistent geometric accuracy, surface finish, and validated material properties year-to-year 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.

Grafana Integration for Enhanced Transparency

Assure integrates with Grafana giving engineers access to the nearly 1,000 different sensor readings that monitor the printing process. Gain detailed insights and manage the key variables governing your additive part production.
