“…There is an ever-growing variety of materials available for 3D printing including plastics, steel, aluminum, sandstone, thermoplastic polyurethane, photopolymer resin, and composite powders (see Shapeways 4 and Bluedge 5 ). The methods used to create prints using these different materials are variable (e.g., Fused Deposition Modeling (FDM), Polyjet Technology, and Binder Jetting, Selective Laser Sintering (SLS), and Selective Laser Melting) (Bluedge 5 and Shapeways 4 , see Walker and Humphries, 2019) as are their resolutions and capabilities. Many different materials have been used in previous paleontological and biological studies, primarily plastics (Huynh et al, 2013;Germann et al, 2014;Mehrabani et al, 2014;Porter et al, 2015;Muscutt et al, 2017;Pearson, 2017;Anderson et al, 2018;Garcia et al, 2018;Voegele et al, 2018;Dievert et al, 2019), powders (Schilling et al, 2013;Crofts and Summers, 2014;Ishida and Kishimoto, 2015;Kolmann et al, 2015;Johnson et al, 2018), and resins (Jonsson et al, 2017;DiMarco et al, 2018).…”
