Step 2: Feed PLA Into a Glue Gun
So this process is fairly simple. Glue gun works same way as 3D pen. it heats up plastic and extruded it so you can draw. in order to be able to feed PLA into a glue gun you need glue stick size PLA. So take multiple sticks of PLA and put them together so it becomes one glue stick size stick and feed it it's a glue gun. Now glue guns trigger is pushing stick itno a gun. Trigger needs better grip to push plastic therefore I wrapped this PLA stick with electrical tape. Now Let Glue gun heat up and start to Draw in mid air just like you would with 3Doodler pen.
