Kig ind i Hybrid 3D-printer

From a week of downtime to just a few days - Ravn Industri focuses on 3D printing

Ravn Industri received assistance from the Danish Technological Institute in a MADE materials demonstration project to develop a hybrid manufacturing method in production. 3D printing of specific steel materials enables time and cost savings in the long run.

This was the solution for the forge and machine company from Bjerringbro, producing stainless steel components for the food industry and single-piece prototypes for Grundfos.

Ravn Industri faced a material challenge in production. They wanted to 3D print components and tools for their customers in 'Tool Steel 11'. It is a type of tool steel known for its good wear resistance. However, they did not know how to do it.

Therefore, in a MADE materials demonstration project, they received help from specialists at the Danish Technological Institute to develop a hybrid manufacturing method that combines technologies to achieve a more efficient production process. Ravn Industri achieved this through a 3D printer that can both deposit and remove material in one system.

There are many other things we can address with 3D printing, where we can save time for the customer and money in the long run.

Learn more about what Ravn Industri has achieved in the project in the video below.

The project focused on developing printing parameters for the specific type of tool steel. Based on these parameters, the company can control the printing process in their hybrid printer and repair tools that break in different production companies:

- The advantage of repairing tools rather than replacing them is a sharp reduction in downtime. If tools need to be replaced, there is often a downtime of a week or more. If we can repair it, we can reduce it to days, maybe hours, explains Karl Fischer, 3D printing specialist at the Danish Technological Institute.

New insights into the potential

The project resulted in new insights into the potential of 3D printing components:

Although Ravn Industri also encountered a challenge with 'Tool Steel 11' becoming hard when printed, the results showed that this material is still optimal because it hardens while being printed.

- The next step after the project is to implement it in the company and towards our customers, and then we have to look at what we can do for future projects. There are many other things we can address with 3D printing, where we can save time for the customer and money in the long run, says Brian Ravn, CEO at Ravn Industri.

About MADE Demonstration Projects

With a MADE Demonstration Project, a small or medium-sized company can receive up to 100,000 DKK in support to solve a specific challenge in the company or test new technology in production.

By being connected with the Danish Technological Institute or another Danish GTS, you gain access to the technologies, knowledge, and competencies necessary to address the specific challenge in the company.

This can be in terms of materials or production. There are ongoing application deadlines for demonstration projects.

MADE Demonstration Projects are made possible with support from the Danish Business Promotion Board.
