POUL DUE JENSEN FOUNDATION RESEARCH “In this research project, we’re speeding ahead in front of the world’s most advanced industrial 3D printer manufacturers on a quest to set the 3D printer free David Bue Pedersen Senior Researcher, DTU Tiny 3D printed rabbit made from plastic by the project 3D printer. The design blueprint is openly accessible for download.

Consequently, the company has only very limited control over the detailed additive process. The project financed by the Foundation intends to create an open architecture around additive manufacturing. This will enable production companies to build their own printers, use whatever powder they need as well as integrate the process as desired in the production. All software and hardware developed in the project will be made freely accessible, and blueprints for the first printer are already ready for download. Component costs are around 20 percent of the cost of a commercial printer of comparable quality. The project sets new standards for precision and surface characteristics for additive manufacturing in polymer, and the little rabbit in the picture is a beautiful example of this. Corresponding activities are underway for additive manufacturing of metal parts. Additive manufacturing Additive manufacturing, also known as 3D-printing, is a family of processes where the desired part is produced by adding material rather than removing it, as when lathing or milling. Marrying additive manufacturing and computer power gives unique new possibilities for rapid manufacturing of very complex parts.
