Phase3D Raises $2.9M to Scale In-Situ Inspection for Metal Additive Manufacturing

Today we're announcing the the close of an oversubscribed $2.9 million funding round led by Quest Venture Partners, with participation from Trinity Capital, Kinisis Ventures, Leroy Street Capital Partners, Asimov Ventures, New York Angels Investment Group, and Chicago Booth Angel Network.

The round also sees Ray Farrell join the Phase3D Board of Directors, bringing more than twenty-five years of experience advising technology companies on intellectual property strategy and commercial growth.

Funding announcements often focus on the number but for us, the more important story is who participated, what that participation says about where additive manufacturing is heading and where they see us in that journey.

The investors in this round have spent decades evaluating emerging technologies, building intellectual property portfolios, commercialising innovation, and identifying category shifts before they become obvious to the wider market. Their decision to back Phase3D reflects something we've believed for a long time:

As metal additive manufacturing moves from prototyping into production, the challenge is no longer whether a part can be printed. The challenge is how manufacturers prove it. We believe in-situ inspection sits at the centre of that transition.

This investment reflects that shift.

"This investment will catalyze faster adoption of real-time quality inspection for additive manufacturing." - Niall O’Dowd, Phase3D

For much of the industry's growth, the focus has been on capability.

Faster systems.
Better materials.
More complex geometries.
Larger build volumes.

Those advances have helped additive manufacturing reach a level of maturity that would have been difficult to imagine a decade ago.

Today, aerospace manufacturers, defense organisations, and industrial companies are producing increasingly important components using additive manufacturing technologies.

As that adoption has expanded, however, the conversation has started to change. The question is no longer whether a part can be printed, it’s how manufacturers prove it.

How do they understand what happened during the build?
How do they identify issues before they become expensive failures?
How do they create confidence in the manufacturing process itself?

These are inspection questions.

Increasingly, they're becoming production questions.

Building the Foundation

Since the beginning, our focus has been on solving a difficult problem: generating robust, repeatable measurements directly inside the additive manufacturing process. That challenge led us to Fringe Inspection™.

Using structured-light metrology, Fringe Inspection™ generates layer-by-layer heightmap data throughout a metal powder bed fusion build, providing manufacturers with visibility into what is happening while the build is taking place.

The goal was never simply to collect data, it was to create information manufacturers could use to make better decisions.

Over the years we've worked closely with customers to bridge the gap between measurement and action. We have seen manufacturers use build data to understand powder bed consistency, identify recoater interactions, analyse spatter deposition, evaluate internal geometries and improve process understanding across production environments.

Developing the technology was only the first step. Turning that technology into a repeatable, deployable product has been the larger journey. That process has shaped both the product and the company and this investment marks a gear change in that process.

What Investors See Coming

One of the most encouraging aspects of this round is the conviction behind it.

This was an oversubscribed round.

More importantly, it brought together investors who understand the challenges of building deep technology businesses and scaling them into meaningful commercial platforms. The strongest validation isn't simply that capital was raised, it's that experienced investors increasingly share the view that in-situ inspection will become an essential component of additive manufacturing as the industry continues to mature.

For years, much of the additive manufacturing conversation has focused on printers but the next phase of the industry may be defined by something different.

Visibility.
Qualification.
Process understanding.
Production confidence.

The further additive manufacturing moves into mission-critical environments, the more important those capabilities become.

That trend is already visible across many of the organisations we work with today.

Phase3D currently supports 25 enterprise customers across aerospace, defense and industrial markets, with deployments and collaborations spanning organisations including NASA, the U.S. Air Force and the U.S. Navy.

These organisations operate in environments where quality is not negotiable. The challenges they face today increasingly reflect where the wider industry is heading tomorrow.

"When the Phase3D opportunity came up, what stood out was the early customer traction. It's special to have aerospace and automotive prime customers while simultaneously addressing top-level initiatives from the Air Force, Navy, and NASA." – Ray Farrell

Ray's observation gets to the heart of why this round happened. The technology matters, but traction matters more. Over the last several years we've seen increasing demand from organisations operating in some of the most demanding manufacturing environments in the world. That demand is helping shape the next phase of additive manufacturing, where process visibility and production confidence become increasingly important.

Why Ray Farrell Is Joining The Board

This round also marks an important addition to the Phase3D team as we welcome Ray Farrell to our Board of Directors.

Ray brings more than twenty-five years of experience advising companies on intellectual property strategy, technology commercialisation and long-term growth. Throughout his career he has helped businesses protect innovation, build defensible market positions and navigate the transition from promising technology to scalable company.

His decision to take an active board position reflects a level of conviction that extends beyond the investment itself as board appointments are long-term commitments. They represent a belief not only in what a company has built, but in what it can become.

As Phase3D enters its next stage of growth, that experience will be invaluable. The challenges ahead are no longer purely technical, they are operational, commercial and strategic.

How do we scale manufacturing?
How do we accelerate deployment?
How do we support a growing global customer base?
How do we continue building a category-defining company?

These are exactly the kinds of challenges that experienced operators and advisors help companies navigate.

From Technology Validation To Commercial Scale

As COO & CFO Ben Ferrar explains:

"We have been through some distinct stages of growth at Phase3D. Initially we worked to develop the technology to ensure robust, repeatable measurements for metal additive manufacturing. Next, we focused heavily on deploying our products to customers to translate metrology data into meaningful decisions. Now, this investment enables us to scale up manufacturing as we drive to become the industry standard for in-situ inspection."

This funding enables us to expand manufacturing capabilities, accelerate deployments, invest further in software and data science, and support a growing number of enterprise and government customers.

In practical terms, that means moving from a high-mix custom build model toward standardised manufacturing at scale.

It means getting more systems into the field, more manufacturers gaining visibility into their processes and it means accelerating the adoption of in-situ inspection across the additive manufacturing ecosystem.

Looking Ahead

The direction of travel is becoming increasingly clear. Additive manufacturing continues to mature whilst production requirements continue to increase.

Expectations around quality, repeatability and process understanding continue to rise and the manufacturers leading the industry are already adapting to that reality. We believe in-situ inspection will play an increasingly important role in helping them do so and this investment gives us the resources to accelerate that mission.

We're grateful to our investors for their confidence, to our customers for pushing the technology into demanding environments, and to the entire Phase3D team for helping build the foundation that makes this next chapter possible.

The future of additive manufacturing will be shaped by many innovations.

We believe in-situ inspection will become a standard part of the additive manufacturing workflow. This investment gives us the opportunity to accelerate that future.
