Researchers at the Technical University of Dresden have formulated and 3D printed TPU-based magnetic elastomer filaments using fused filament fabrication (FFF) technology

Magnetic "smart materials"

The term "smart material" has been around for a few years to describe materials that have been further functionalized with special properties after formulation

There are two main types of MREs: anisotropic structural MREs and isotropic MREs

Pre-Constructed Magnetic TPU

The researchers' goal is to use FFF to fabricate pre-constructed (anisotropic) MRE parts

To align the magnetic material in the filament, the team installed two ring magnets in the space just above the heating block

After CT processing the printed samples, their microstructural distribution was observed, and the researchers confirmed that the new printhead successfully constructed the magnetic additives in the filaments before printing

More details of the study can be found in the titled "Field-structured magnetic elastomers fabricated from thermoplastic polyurethane-based fused filaments

Filament research and development is very important in the field of additive manufacturing, because when producing professional and industrial parts, the raw material is as important as the machine it is used in
