The 3Doodler 2.0 launch in 2015 introduced a redesigned, significantly smaller, lighter, and sleeker aluminum 3D printing pen based on community feedback. This updated version featured improved mechanics, such as a quieter airflow and a re-engineered drive system, and raised over $1.5 million on Kickstarter in a rapid follow-up to the original, successful, first-generation pen.
