The 3Doodler can be used as a plastic welding tool. If you have something made of ABS plastic (the most common form of plastic) you can repair it with the 3Doodler. For example, two broken parts can be welded back together by “drawing” a plastic weld where the parts are broken. In addition to household repairs, this is quite handy for makers who are using traditional 3D printers. With the 3Doodler PRO, the wood filament can be used to repair holes in wood, and it can be sanded and stained!
If you are having trouble bonding one like plastic to another, simply press the hot nozzle against the part you are trying to attach to for a few seconds longer. This helps it melt a little so that it can bond with the new material.
