ICYMI: Multi-headed 3D printer, robo plant grafting and more

Today on In Case You Missed It: Autodesk built a 3D printing assembly line that gives different jobs to several print heads, allowing them to work collaboratively and quickly spit out a finished project. Clemson University used a Korean robot to graft up to 3,000 plants an hour. And a Kickstarter project for an augmented reality shirt is designed to teach kids and interested adults all about the internal organs. The Milky Way is looking stunning in newly released photos from the APEX telescope. As always, please share any great tech or science videos you find by using the #ICYMI hashtag on Twitter for @mskerryd.
