Freemelt, a Sweden-based steel 3D printing firm, has introduced the completion of a SEK 15M ($1.6M) capital funding spherical led by enterprise capital agency Industrifonden.
The funding spherical additionally included Freemelt’s present traders, and might be utilized by the corporate to gasoline the subsequent part of its development. Freemelt goals to “drive the steel 3D printing revolution ahead” utilizing its open-source electron beam melting (EBM) 3D printing know-how.

Open-source EBM 3D printing
Based in 2017, Freemelt has developed an EBM 3D printer, titled Freemelt One, supposed for analysis and improvement into steel supplies for additive manufacturing. A key function of the Freemelt One EBM 3D printer is the small quantity of powder that’s reportedly required for the system to function. By designing the system in order that it wants little materials funding, Freemelt seeks to make the testing of various steel powders reasonably priced and quick for customers.
The corporate’s web site states that the majority future functions for 3D printing require supplies which can be but to be developed and made appropriate with the know-how. Freemelt claims that industrial steel 3D printers are solely in a position to make use of a number of choose supplies, limiting the chances for 3D printing to succeed in new functions.
With its EBM system, nevertheless, Freemelt goals to develop 3D printing for future supplies utilizing a collaborative and open-source method: “The ecosystem will promote the cooperation between analysis and business. This can allow steel 3D printing to develop a lot sooner than the person companions can handle on their very own, and hold the event momentum going by combining their assets.”
“Our software program is actually open-source […] The person can adapt and evolve the code, and share it inside the group, to speed up the event of tomorrow’s supplies.”
Freemelt’s open-source EBM 3D printer will permit customers to examine, validate, alter and develop the software program code themselves. An open-source group will encourage collaboration between customers, the place they’ll be capable to ask for and supply assist, develop new options, share concepts in scripts and software program updates, and create new supplies with out software program restrictions.

Steady improvement for EBM
Electron Beam Melting, or EBM, is a 3D printing course of permitting for the fabrication of steel elements utilizing an vitality supply able to melting steel powders layer-by-layer to supply complicated, industrial-grade elements. It differs to SLS in that its vitality derives from a beam of electrons, fairly than photons.
Sweden-based 3D printer producer Arcam was the unique firm to construct an EBM system. The agency was additionally a part of Industrifonden’s funding portfolio from 1999 to 2015. Since then, Arcam has been acquired by American conglomerate GE as a part of a $1.four billion deal.
In addition to Freemelt nevertheless, varied different corporations are coming into the market alongside Arcam with EBM methods. Just lately, Wayland Additive, a steel 3D printing start-up primarily based in West Yorkshire, UK, raised £three million in funding to develop an EBM 3D printer for aerospace and medical industries.
Moreover, Ruselectronics, a Russian holding company and a subsidiary of state-owned Rostec, has begun growing an EBM 3D printer for aerospace functions. The analysis and improvement work might be carried out by Toriy Scientific Manufacturing Affiliation (НПП Торий).
