General Usage of an Ender 3 Pro
Multi-color Print
An Ender 3 Pro is just the beginning. There are many far more advanced printers. Not just the printer matters when you are trying to print more complex things. The filament matters too. Depending on the filament, your creation could bend and stretch without breaking or it could be brittle. It could even be so that your creation is not bendy, but it is unbreakable. There are also more complex printers. Some can print things that are really tall and others can't. Also, some printers are more capable in general than other printers. With any 3D printer you must make sure that you take proper care of it and do not misuse it because it is an amazing tool that is expensive. If you are missing a screw or a bolt, you can just find a gcode for that specific bolt and print it. If you want a cool little toy to play with or a sculpture it can just be printed. Below is a link to a website with a lot of designs that you can use.
