Belts, 3D Metal Printers, Detectable Warning Panels, Model Stirling Engines

How It's Made – Season 32

Carefully inspected cowhide is cut into strips, bevelled, dyed, decorated and fitted with buckles to produce leather belts. Precision components are assembled into machines that deposit and laser-fuse metal powder, glass-reinforced resin is compression-moulded into tactile warning panels, and finely machined pistons, cylinders, crankshafts and flywheels are combined in working model Stirling engines.
