![]() The effect of changing infill between 15% and 20% on estimated print time and material use was negligible. The slicing software investigated are Cura LulzBot Edition 3.6.20, GrabCAD Print 1.43, PreForm 3.4.6, and PrusaSlicer 2.2.0. Print settings investigated were infill percentage, layer height, and model orientation on the print bed. Material quantity was used to calculate estimated model cost. For each printer and corresponding print setting, the slicing software provides a print time and material use estimate. Seven representative orthopaedic standard tessellation models derived from CT scans were imported into the respective slicing software for each 3D printer. This study investigates six commercially-available 3D printers: Prusa i3 MK3S, Formlabs Form 2, Formlabs Form 3, LulzBot TAZ 6, Stratasys F370, and Stratasys J750 Digital Anatomy. The estimated cost and print time per model for 3D printers have not yet been compared with clinically representative models across multiple printing technologies. 3D printed patient-specific anatomical models have been applied clinically to orthopaedic care for surgical planning and patient education. ![]()
