“…While there are many scaffold fabrication techniques like emulsion freeze drying ( Sultana and Wang, 2008 ; Qian and Zhang, 2011 ; Sultana and Wang, 2012 ), gas foaming ( Manavitehrani et al, 2019 ; Luo et al, 2021 ; Chen Y et al, 2021 ), porogen leaching ( Bhaskar et al, 2018 ; Poddar et al, 2021 ; Santos-Rosales et al, 2021 ) or phase separation ( Ferrolino et al, 2018 ; Abzan et al, 2019 ; Zeinali et al, 2021 ), more recently additive manufacturing (AM) gained an increased interest for scaffold fabrication ( Shick et al, 2019 ; Szymczyk-Ziółkowska et al, 2020 ; Veeman et al, 2021 ). Generally, the term AM refers to a group of additive manufacturing techniques used to produce a scale model of a physical part or assembly as a three-dimensional model as quickly and inexpensively as possible.…”
