An example of 3D Printing in-action!
This print is made of PLA and is being printed on the Ultimaker 2 Extended.
This is extrusion printing. The PLA plastic (that kind of looks like one long piece of plastic spaghetti wrapped around a spool) is heated and pushed (extruded) through the nozzle. The nozzle moves along the print, depositing a thin layer of this plastic.
It builds your print layer by layer, which is why it can take a long time for larger prints.
You can also see there is a thin base layer that extends outside of the print. A good base layer is the basis of a good print! So if you want to start a print and walk away you should at least check the base layer and make sure it has gone down properly. If it hasn’t, some common errors might be that the plate is not level or the temperature is off.
