The 3Doodler Pro+ is the most comfortable pen to hold and gave us the greatest amount of control over our lines. It’s one of the most flexible pens we’ve tested when it comes to materials, too: While the Create+ is compatible with PLA, ABS, and Flexy plastics, the Pro+ adds additional options like wood (blended with plastic), copper (also blended with plastic), and nylon. It also allows for precise temperature control, which makes it easier to work with unusual third-party materials. However, these benefits weren’t enough for us to recommend the Pro+, because it costs more than three times as much as the Create+. That pricing rules it out for anyone but the most devoted 3D pen users.
