“…Numerous applications for the medical field have been developed using AM technology, such as anatomical mockups for surgery training, planning or simulation [ 1 , 2 ], personalized surgical guides [ 3 , 4 ], tissue engineering scaffolds [ 5 , 6 ], customized implants [ 7 , 8 ], etc. Not all these applications are based on FFF, which usually uses thermoplastics, such as ABS (acrylonitrile butadiene styrene), PC (polycarbonate), PLA (polylactic acid), PETG (polyethylene terephthalate glycol), Nylon PA (polyamide), PEEK (poly-ether-ether-ketone) [ 9 ], or their composites.…”
