Cheap 3D‑Printed Torso for STEAM
A community maker post showed a full human torso model printed on a Prusa with PETG filament—presented as an affordable anatomy tool for resource‑limited STEAM classes. The build was shared with part lists and printing tips for classroom use. (x.com)
A Prusa showcase torso print used 747 g of filament and ran for 24 h 12 m on a Prusa CORE One L at default size, offering a concrete benchmark for full‑torso FDM prints. (printables.com)) Comparable community builds vary in scale, including a Thingiverse anatomy torso described as “almost 3 feet tall” created for a children’s museum, implying some classroom‑ready models exceed ~90 cm in height. (thingiverse.com)) A community anatomy upload that includes Braille labels explicitly recommends printing the detailed organ surfaces in PETG and specifies a 0.20 mm extruder width for reliable fine detail on small features. (thingiverse.com)) Using the 747 g filament example and current U.S. PETG price ranges of roughly $20–$50 per kilogram, material cost for a single full‑torso print works out to about $15–$37 in filament alone. (printables.com)) Several maker designs break the torso into removable organs and sectional parts to cut each print into shorter jobs and speed classroom turnover; modular STL sets explicitly list removable organs and join points for assembly.
