Challenges and Innovations in Polymer Additive Manufacturing
Additive Manufacturing of Polymers: Technologies, Materials, and Perspectives

The rapid evolution of additive manufacturing technologies relies largely on the development of polymer materials specifically formulated to meet the unique demands of additive processes, including layer-by-layer fabrication, high thermal gradients, rapid solidification or polymerization kinetics, and the resulting mechanical anisotropy. Materials intended for additive manufacturing must therefore exhibit rheological, thermal, and chemical properties compatible with the deposition conditions to ensure the stability of the filament or deposited layer, good interlayer adhesion, and satisfactory dimensional stability.

In the early days of 3D printing, the use of standard...
