3Doodler was a pioneer of his time and many other 3D pens were developed afterwards. The idea is to only use the end of a 3D printer and put it in the form of a pen. With the extruder in your hand you become the printer moving it’s printhead freely around. As a result, there is no limited building volume for the 3Doodler and you can draw freely. This is why the 3Doodler filament cartridges are an advantage since they enable a free 3D printing experience with the pen compared to material roles from other machines.
We recommend using the original 3Doodler filament cartridges, since other suppliers have a similar price. This leads to a safe application of the 3D pen and you can buy the material on Amazon.

Advantage of 3Doodler filament cartridges
Compared to other 3D pens, the 3Doodler has filament cartridges and not material roles. This has the advantage that material does not hang out at the end of the 3D pen, which disturbs you while drawing. The 3Doodler filament can be purchased directly from 3Doodler or on Amazon which we recommend to secure high quality results, as these are definitely worth the price. Although the 3D Doodler filament cartridges seem relatively short, they nevertheless hold themselves relatively long.
Disadvantage of the rods or cartridges
The material cartridges become problematic only if they get too short and move too far into the 3D pen. Then it is difficult to get them back out again as they do not simply roll backwards automatically. Therefore you have to remove the print tip with the 3Doodler tool and squeeze it out with a needle — this is at least the best approach. Even if it sounds complicated, one quickly gets used to the process. On the other hand, you can simply finish the existing material and add another 3Doodler filament.
These disadvantages make not difference compared to other 3Doodler filament cartridges. Nevertheless, it is a disadvantage of the bars compared to filament roles and we wanted to mention this factor at this point.
For the 3Doodler pen, we recommend the appropriate material cartridges from the manufacturer for the device. The 3Doodler filament is ideal for the 3D printing pencil and we do not recommend experimenting with other products. It can cause problems to use the normal filament rolls from other 3D pens or not work at all. Consequently, such attempts are not worthwhile, since you do not save money or increase the quality by doing so.
