3D-printing pen raises $500,000 in one day on Kickstarter

Remember 3Doodler — the world’s first 3D-printing pen that took Kickstarter by storm a little over a year ago? By using a special, quick-hardening filament, it allowed users to draw free-form three-dimensional objects by hand, instead of drawing out designs on a computer and using a printer to bring them to life. It was a groundbreaking idea, and gave people a new way to create things, but it was also somewhat squirrely and imprecise. For all of it’s creative potential, it was more of a fun toy than a serious design tool.
