Researchers at the Fraunhofer Institute for Machine Tools and Forming Technology IWU in Chemnitz, Germany have developed **** Extrusion Additive Manufacturing (SEAM), a system that is eight times faster than conventional 3D printing.

According to researchers, the SEAM system takes only 18 minutes to produce a plastic component 30 centimeters in height, while some FFF 3D printers can take up to an hour to produce a pocket-sized souvenir. The process achieves this production speed by combining 3D printing with machine tool technology. To process the plastic, the researchers use a specially designed unit that melts the raw material and ejects it at a high output rate. This unit is installed above a construction platform capable of swiveling in six axes.

Times - Processes - Production - Times - Components

“This enables us to print eight times faster than conventional processes, enormously reducing the production times for plastic components,” said Dr. Martin Kausch, a scientist at Fraunhofer IWU.

The hot plastic is deposited in layers on the construction platform. The motion system of the machine ensures that the construction panel slides along under the nozzle in such a way that the previously programmed...
