Post‐extrusion process for the robust preparation of highly uniform multiphase polymeric 3D printing filaments

Fused filament fabrication 3D printing demands the preparation of polymeric filaments of highly uniform dimensions in order to achieve the best possible mechanical performance. This stringent requirement is a challenging task and becomes even more difficult when multiphase hybrid polymers are used. In this work, a post‐extrusion setup is presented, allowing for the preparation of immiscible quaternary polymeric blend filaments of highly stable...
