Towards Industrialization of Poly-Ethylene Terephthalate Glycol Material Fabricated by Fused Filament Fabrication Technique

The material properties of Polyethylene terephthalate glycol (PETG) can be highly improved when adding other polymers or materials, however, we focus on this mini review only on pure PETG material fabricated by Fused Filament Fabrication (FFF) technique to overcome the corresponding issues with the object of industrializing the pure PETG material. In our previous works, deterioration concept was introduced to extend far beyond the concept of traditional failure concept, and its corresponding cases were classified into two categories: certainty and uncertainty cases. So, to industrialize this material fabricated by FFF technique, only certainty cases (reasons behind deterioration cases (defect/ fault/ failure/ damage)) can be characterized. These cases are treated here and next compared to other polymers such as Poly lactic acid (PLA) and/or Acrylonitrile Butadiene Styrene (ABS) materials if needed to overcome the different issues occurred when the studied this material by FFF technique. Several roadmaps are proposed considering the use of advanced techniques such as Artificial Intelligence (AI) and multi-level optimization.
