LEAM: Enhancing Layer Density in Large-Format 3D Printing

LEAM, a spin-off from the Technical University of Munich, has created the DEMEX system, an add-on designed to improve the performance of large-format 3D printers. The DEMEX system integrates LED emitters and infrared cameras strategically positioned around the extruder nozzle.

Using the LED emitters, the DEMEX system precisely heats the substrate in a localized manner directly in front of the nozzle, guaranteeing optimal welding of the layers. Furthermore, a closed-loop control system with infrared cameras ensures that the desired target temperature is consistently achieved. This precise control of temperature enables significantly improved layer adhesion and mechanical properties in large-format 3D printed parts.

The result is a dramatic improvement in part strength. Previously, the maximum Z-resistance achievable was limited to 60%. With the DEMEX system, workpieces can now reach 100% of the resistance specified in the material manufacturer’s data sheet – in all directions! This breakthrough unlocks new possibilities for the production of robust and reliable large-scale 3D printed components.
