Zero-Gravity 3D Printer: In-Space Additive Manufacturing

Space stations can't ship a spare bracket next-day — so orbital 3D printers build spacecraft parts on demand, one molten bead at a time, in an environment with no gravity to help or hinder the process. This simulator renders a real FDM print head laying down a spiral toolpath that builds a lattice bracket layer by layer, driving extrusion width from volumetric flow conservation and interlayer bond strength from Newton's law of cooling — including the microgravity twist that without buoyancy-driven convection, beads cool more slowly than on Earth, changing how hot, fast and thick you can safely print. Four controls (nozzle temperature, print speed, layer height, chamber temperature) feed the live bond-strength bar, extrusion-width readout and estimated print time exactly as they would on a real orbital printer's control panel.
