DigitalRecycle - Digitized material cycle for the additive manufacturing of recycling-optimized moulding tools

Digitized material cycle for the additive manufacturing of recycling-optimized moulding tools.

Project Partners
KraussMaffei

Duration
01.01.2023 – 31.12.2025

Funding authority
Bavarian State Ministry of Economic Affairs and Media, Energy and Technology

Motivation
As part of the DigitalRecycle project, a new, digitally supported material cycle is being developed for the extrusion-based additive manufacturing of mold tools for the prototype construction of light aircraft. These tools are intended to replace ureol tools that are difficult to recycle.

Method
TUM is investigating the material behavior of short-fiber-reinforced thermoplastic composites after multiple recycling and reprinting as well as the mechanical shredding of printed components and direct printing with recyclate (without prior processing of the recyclate into granulate). This can improve process reliability for the use of recyclate in large-format 3D printing.

Acknowledgement
The Chair would like to thank the Bavarian State Ministry of Economic Affairs, Regional Development and Energy for funding the "DigitalRecycle" project under the "HAMI - Holistische Air Mobility Initiative Bayern".
