About the PrintRite3D® QA Solutions

What solutions do you offer?

Our additive manufacturing in-process quality assurance system is called PrintRite3D®. The PrintRite3D system provides real-time melt pool monitoring and analytics to ensure in-situ quality assurance for additive manufacturing/3D metal printing. PrintRite3D uses multiple sensors, data acquisition and computing hardware, along with our proprietary software, for comprehensive quality management of AM processes. PrintRite3D allows the user to see, analyze and ensure the quality of the 3D-printed part while it’s being made. This saves time and money by reducing or even eliminating the need for destructive testing or inconsistent scanning of complex parts. PrintRite3D is available for use on laser powder bed fusion and directed energy deposition systems both as a third-party retrofit and a machine OEM integrated solution. Learn more about PrintRite3D.

How does PrintRite3D work?

Sigma Additive Solutions’ PrintRite3D® real-time melt pool analytics with Automated Anomaly Detection is a way to analyze the structure of a part and any variations in its creation when compared to specifications, while the part is being manufactured using additive technology. Our system identifies the thermal signatures of the melt pool (printed metal material) while the part is being manufactured. Our methodology detects and maps any flaws in real-time.  Learn more.

What’s the latest release of PrintRite3D?

Our latest release is PrintRite3D 7.0, which offers a substantial leap in the quality of the metal 3D printing industry while increasing overall manufacturing efficiency and improved economics. New features in PrintRite3D 7.0 include:

  • Calibrated Melt Pool Temperature Measurement
  • Melt Pool Cooling Rate Measurement
  • Recoater Interaction Detection
  • Machine Learning for detection of anomalies
  • Predictive Modeling for establishing the Digital Twin

Do you have a system for DED monitoring?

PrintRite3D IPQA® for DED Monitoring is available as a standalone system or as a retrofit for your current AM printer, including:

  • Melt pool intensity captured and monitored in real-time using multiple photodiode sensors integrated with the machine optics.
  • Proprietary algorithms convert raw data into engineering-based quality metrics to define melt pool quality.
  • Raw data is captured at 200KHz, product quality visualizations in 2D and 3D
  • Automatic anomaly alerts notifications, production status dashboard and SPC (statistical process control) quality trend charts.

About Solution Benefits

What benefits do Sigma Additive Solutions customers receive?

The PrintRite3D system quickly discovers potential anomalies and incorporates machine learning in conjunction with developed metrics to map those metrics to the captured build data. This gives you the ability to achieve real-time defect detection, reduce post-production testing and costs, reduce risk, improve safety, and create a certification framework that serves the needs of end-users, printer manufacturers and standards organizations.

Can PrintRite3D help improve my 3D metal printing processes?

Yes. Improved part quality and overall manufacturing efficiency go hand-in-hand. With PrintRIte3D you will be building quality into the part, since it can’t be inspected into the part. PrintRite3D users can adjust the process in real-time to further assure quality and thereby gain confidence in their process consistency from one build to the next. They can compare each part to established baselines during the build, reducing post-process time and boosting process repeatability. Users will also see potential part anomalies and their locations and reduce the amount of costly CT scans required.

Can PrintRite3D help make my metal 3D printers more consistent?

PrintRite3D focuses on monitoring and analyzing the melt pool, and identifying certain anomalies that occur.  However, there are many influences in the quality of a melt pool, including gas flow, evacuation of soot, laser degradation, parameters, multi-laser coordination, etc.  Using PrintRite3D to understand the specific impact of these factors on the melt pool, and providing better control over them, will increase consistency between machines while boosting throughput and OEE.

Why would I consider a third-party agnostic solution like PrintRite3D instead of an OEM solution?

There is a potential conflict of interest when an OEM uses their own monitoring tool to validate the quality of their production equipment. By contrast, Sigma Additive Solutions is the leading third-party solution provider for unbiased in-situ monitoring. Unlike machine OEMs, in-process quality assurance is our passion and entire focus. PrintRite3D is the standard-bearer for real-time monitoring and analysis with traceability to NIST; providing capability, accuracy and analysis features far more advanced than OEMs offer. For multi-OEM installations or hybrid LPBF/DED installations, PrintRite3D is a cross-platform, cross-technology solution ensuring all your builds are evaluated consistently.

How can I evaluate PrintRite3D for my needs?

It’s important to understand exactly how PrintRite3D can find and interpret anomalies in YOUR specific parts.  The good news Is that we have a special program for that!  For a limited investment, we will build your part on our machine, collect the build data using PrintRite3D, and load the data to a secure location so you can experience the power of PrintRite3D first hand.  We will also assign an application engineer to help you acclimate to the software quickly so you can fully explore its features and tools.

About the Technology

Will PrintRite3D work in my current environment?

The PrintRite3D system is great for both heterogeneous (multiple printer manufacturers) and homogenous (single manufacturer) equipment environments. It is printer-agnostic and can be adapted as a third-party retrofit onto any manufacturer’s metal 3D printing machine. PrintRite3D is also available as an OEM license package to metal AM machine manufacturers.

Is PrintRite3D based on industry standards?

Yes. Our mission is to set the quality standard for real-time additive manufacturing and help accelerate the worldwide adoption of 3D metal printing. Sigma Additive Solutions works closely with international standards organizations, renowned universities, research organizations, advanced manufacturers, and leading design and simulation software companies.

Can I use my machine’s existing melt pool monitoring hardware for PrintRite3D?

PrintRite3D requires the collection of high-density spectral data from the melt pool to enable its advanced features and algorithms. It’s best to contact us at to discuss your specific monitoring and analysis needs for a final determination.

About Sigma Additive Solutions

Who is Sigma Additive Solutions?

Sigma Additive Solutions (NASDAQ: SASI) is a leading provider of in-process quality assurance (IPQA®) software to the additive manufacturing industry.
