Slovak researchers develop new “extremely strong” hybrid PETG composites

[Allen]

Researchers from the Slovak Academy of Sciences and the Slovak University of Technology have developed a set of new, low-cost hybrid materials for FFF 3D printing. By reinforcing virgin and recycled PETG filament with expanded graphite, carbon fiber, and combinations of both, the team was able to enhance the mechanical and thermal properties of the […]

This is similar to carbon fiber reinforced PLA, which is much stronger than regular PLA. This type of material has the possibility to produce very strong parts. And the concept of fibers that run at different angles can create a much stronger material than even pure PLA, sort of how the layers of plywood give more added strength compared to regular wood alone (see below).
