TissueDB/Materials/PETG

PETG (Polyethylene Terephthalate Glycol) is a thermoplastic copolyester used in 3D printing for medical simulation models. It offers better impact resistance than PLA while being easier to print than ABS. The one build source in this database that evaluates PETG for bone models rules against it: PETG is grouped with ABS and engineering co-polyester as too soft to tolerate drilling of a self-drilling 4.5 mm Schanz screw, and PLA is specified instead.^[1]

Bone				No simulator in this database uses PETG for bone, and the one source that tested it advises against it for drilled bone models.^[1]
