On 24.03.2022, four employees of the LCC went to DEKUMED in Bernau am Chiemsee for the preliminary acceptance of the new reactive 3D printer. The system consists of a 3-component dispensing system and an ultrasonic mixing head which is attached to a CNC portal for 3D printing. The task of the ultrasonic mixing head is the homogeneous mixing of the components resin and hardener by cavitation and the following extraction and defined depositing of the material through a nozzle. 
As part of the LargeDuroPrint project, which started in February 2022, a material and process development for extrusion-based, large-volume 3D printing of reactive resins using ultrasonic mixing heads is being carried out together with the project partner University of Bayreuth. We would like to thank the StMWi Bayern for the funding within the BayLu25-II funding program.
