The only worse thing than watching your 3D Pen run out of filaments in the middle of an artwork is looking at the refill package and finding it empty. It’s like your creativity has just been sucked out of you – never to return again. Do not let this happen. Stock up on high quality 3D pen filament before you begin important projects.

Note: If you have a 3Doodler pen it is better to use filament that is made by the company, since the pen rotates the filament and expects a straight strand. People have managed to use 3rd party filaments with their 3Doodler’s before but you must make sure you get 2.85mm. You can find filament for the 3Doodler Start here and the 3Doodler Create here.

Why Quality 3D Pen Filaments Matter

It’s important not to skimp out on 3D pen filaments. A poor quality filament will cause painful jams that will require you to let your pen cool before cleaning it out with special tools. Bad filaments can also come out unevenly, which can make it impossible to make complex objects.

Feel free to buy a cheap filament to use to learn or for when you are prototyping. But when you decide to make a cool object, choose high-quality ABS or PLA filaments to avoid headaches. The good news is that using our reviews above you don’t have to sacrifice quality for price. The 3D pen filaments that we chose are affordable and good quality.

Warning; 3D printers should never be left unattended. They can pose a firesafety hazard.
