FDM 3D Printer Simulator (2D)

This 2D side-view cross-section shows an FDM 3D printer building a vase-shaped object layer by layer: the nozzle sweeps across X to trace each layer's outline, the bed steps in Y, and the gantry lifts by one layer height in Z whenever a layer finishes. Adjust the layer height to trade print resolution for speed, change the print speed to see the nozzle move faster or slower, and tune the nozzle temperature to keep extrusion in its sweet spot — too cold under-extrudes with gaps, too hot strings and droops. Live readouts track the current layer, overall progress and an estimated time remaining computed from the actual path length and settings.
