It’s hard to believe, but 3Doodler launched the popular Kickstarter for its first plastic-extruding pen almost three years ago. Now, the company is back with the 3Doodler Start, a kid-friendly version of the device that boasts a safe-to-touch design with no hot points and a new eco-plastic material that makes building creations safe and fun. The device is available for pre-order now on the company’s website for $39.

As with most 3D-printing devices, the Start requires a bit of patience when building from scratch given the new eco-plastic material, but the company has introduced a line of cool little stencils called DoodleBlocks that are included with the “Super Mega Pack” so that young builders can 3D-print complex inventions from their new device.

I sat down with 3Doodler co-founder Daniel Cowen to check out the new device, see what it looks like in action in the video above.
