With FDM ("plastic glue gun") printers, this process typically involves a program called a "slicer". You export the model from the 3D modeling program (.amf, .wmf and .stl are the most common formats) and input that into the slicer program, which "slices" the model into layers, and outputs commands to the printer (commonly G-code) into a text file. The text file is then transported to the printer (via network, or modern sneakernet aka SDcard) where you load it and start the printing process. Common slicer programs are Cura https://ultimaker.com/software/ultimaker-cura and PrusaSlicer https://www.prusa3d.com/prusaslicer/ In general, it is easier to start with the slicer program recommended / supplied by the 3D printer manufacturer - they have taken the guesswork out of the settings, which gives you better printing results from the start. If I have to choose between Cura and PrusaSlicer, I prefer PrusaSlicer because it has an easier user interface. HTH -- Regards, Torfinn Ingolfsen
