🛠️ How They Work FDM (Filament-Based Printing) FDM printers work by heating a thermoplastic filament. They extrude the filament through a heated nozzle, layer by layer. This process forms an object. A stepper-motor-controlled gantry moves the nozzle (or the print bed) in X, Y, and Z axes. Key technical points: Resin Printing (SLA, MSLA, DLP) … Continue reading FDM vs Resin 3D Printing: Key Differences Explained
