Tunnel Boring Machine

TBM for resin printer only, Full scale model. Will need to be reduced for your preference. I have printed it at 9%. I have added my printer supported version to the files, unsupported STLs are also available provided x 3.
This Tunnel Boring Machine model is an excellent choice for resin 3D printing because its complex geometry, fine surface detail, and mechanical features are exactly where resin printers excel. The cutter head, segment rings, hydraulic rams, and panel lines benefit from resin’s high resolution, producing crisp edges and sharp detail that would be lost or softened on most FDM printers. The mostly cylindrical forms also print cleanly with minimal layer visibility, giving a smooth, professional finish that suits display pieces or engineering demonstrations. Overall, it’s a model that rewards precision printing, making resin the ideal medium to showcase the intricacy and realism of a TBM.
