Directed Energy Material Extrusion - DEMEX

Directed Energy Material Extrusion - DEMEX yra paremtas LEAM Technologies

LEAM Technologies yra startuolis, sukurtas iš Miuncheno technikos universiteto. Jie siūlo pramoninį kraštu pagrįstą sprendimą išplėsti didelio formato 3D spausdintuvus su temperatūros stebėjimu ir aktyviu valdymu. Tai leidžia techniškai reiklius plastikus, tokius kaip PEEK ar panašiai, pirmiausia apdoroti su didelio formato 3D spausdintuvais. Technologija daugiausia naudojama energetikos, automobilių, kosmoso ir bendrosios mechanikos inžinerijos sektoriuose.

Kodėl Improve layer adhesion in large format AM?

DEMEX solves the problem of insufficient layer adhesion in large format Additive Manufacturing. The system uses light generated by high-power LEDs to heat the substrate locally. The light is focused to a spot in front of the nozzle. The optimum temperature for layer bonding is ensured at the interface without risking stability. Due to visible, broad-spectrum light, DEMEX avoids laser safety regulations.
Parts printed with DEMEX show isotropic properties for tensile strength as the weak interface between layers is eliminated. The technology can be used with any thermoplastic polymer and is relevant for demanding applications, where PEEK, PEI, PESU, or other high-performance polymers are processed.
DEMEX is retrofittable on any new or existing large format 3D printer and integrates using standard communication interfaces.
LEAMs product on Siemens Industrial Edge expands value share from Siemens Numerical Control to Edge Computing and quality assurance software in future LFAM machines.

Pagrindinės Funkcijos

Seamless integration in any new or existing machine

Whether you’re setting up new LFAM machines or upgrading existing equipment, our modular solutions use open communication standards, allowing fast adaptation to different configurations and broad compatibility with machine controllers, with a easy to use, stand alone HMI.

Active temperature regulation of the printed part

DEMEX is designed with full ring sensor and emitter arrays, providing 360° thermal coverage around the nozzle - without the need for any moving parts. This enables precise temperature measurement and correction through active heating in every direction.

Usable with high-performance polymers such as PEEK, PEI, etc.

We use high-intensity LED-based emitters - offering the perfect balance of power, responsiveness, and safety. This allows the system to adapt to the entire range of materials, from commodity plastics to high-performance polymers.
