How OS/OD/OH is used?

The Freemelt products and open systems enable/unlock new potentialities for R&D, which is needed for innovation. In closed system you cannot be extremely creative (limitation of your machines) Example of products are:

  • Control software: coordinator machine that controls the flow of the building process;
  • Data format: defines how to import data into the system (libraries with free licenses);
  • Open Hardware (only some components, excluding mechanical components in order not to harm the system or humans).

Research and innovation is the Freemelt first priority. They developed an OD format and opened their system and software for different strategic advantages:

  • Regulations in closed systems are an obstacle for AM: The open approach is very important for research but also for mass manufacturing. You don’t have to care about closing your code and protect your IP;
  • Openness is a business advantage to advance AM;
  • Generate more collaborations (manufacturing is a very competitive field);
  • In AM, you want second sources and equipment. Other companies should not fail to deliver. Giving more compatibility is necessary.
