You know we really should do a segment entitled “What 3D Printers Can Do Now.” (effect and booming echo voice). A startup called MarkForged is taking 3D printers to the next level using carbon fiber. Why? Because carbon fiber is stronger, that’s why. They wanted to overcome the strength limitations of other 3D printed materials that have been created.
