About Freemelt

We are Freemelt, the catalyst of the metal 3D printing revolution.

An agile and experienced team that will fundamentally change the metal 3D printing industry, with some of the industry’s top innovators and new groundbreaking technology.

We know that a revolution is a collective effort that can’t be won on your own. Collaboration is key to our mission, with an ecosystem where everyone can participate with their unique skills and experiences, to drive us forward faster together.

Our broad network spans from the universities that do fundamental research to the forerunners of industrial volume production with metal 3D printing.

We are a small, efficient team that has endured great challenges and prevailed. We work and operate as one, and don't waste time on administrative overhead and status reports. We innovate!

The revolution

The metal 3D printing revolution is a materials game.

The majority of future 3D printing applications require materials not yet developed for additive manufacturing.

The commercial metal 3D printers use only a handful of different materials, and are not designed to develop new ones.

This lack of available materials severely limits the technology’s ability to reach new applications.

Future metals

Our 3D printer is designed for metals not yet known to mankind. Materials engineers dream about, that will give us lighter, stronger and more efficient products. Other 3D printers mimic alloys already developed for traditional manufacturing and therefore do not release the true power of 3D printing, the metals we can’t make today.


The ecosystem will promote the cooperation between research and industry. This will enable metal 3D printing to grow much faster than the individual partners can manage on their own, and keep the development momentum going by combining their resources.

Open source

Our software is truly open source, a revolution in an industry where "open" often means "not totally locked down." The user can adapt and evolve the code, and share it within the community, to accelerate the development of tomorrow's materials.

Open Source

Open source accelerates many industries and Freemelt is the catalyst for the additive manufacturing industry, with truly open source software and hardware.

When something is released under an open source license, the users are granted far more rights than stipulated by copyright law.

This is becoming the norm in many industries, where the key to fast progress is collaboration – if we combine our efforts we can move faster than if we work alone.


The users are free to use and alter the software to their specific needs.

No black box

The software is open and can be inspected and validated.

No lock-in

Users can develop the software independent of the original creators.

An open source AM system makes it possible to:

Ask for and provide help with development in an open source community.

Develop new and improved features in systems and software.

Share ideas and methods in form of scripts and software updates.

Develop new materials without any software restrictions.

Freemelt ONE

The electron beam powder bed fusion 3D printer optimized for materials R&D.


Outstanding and consistent vacuum quality, 10−6 hPa, due to low outgassing materials and clever design preventing moisture-absorbing metallization.


6 kW diode electron gun for fast processing and very high powder bed temperatures, >1200 °C. Enables hot processing of crack-sensitive materials and refractory metals.


Powder feeding and distribution system fully protected against heat, evaporation, electrons and X-rays during e-beam operation.


Designed for smooth chamber cleaning, with exchangeable panels and easy access. The operator can clean the system and load another material in a couple of hours.


Stiff chamber preventing thermal distortion. Minimum use of degradable elastomer vacuum seals near hot regions.


Several auxiliary ports where R&D instruments for in-situ process monitoring can be attached. Free line-of-sight into the chamber, from several directions.


Small vacuum chamber, 70 liters, with two turbopumps ensures fast pump-down and short turnaround times.


Powder feeding system allows builds even with small powder quantities.
