3D Printing and the Northern Walking Stick Insect: SciShow Talk Show #18

The video features a discussion on 3D printing with Ben Malouf, who shares insights into his work at Acuity Design, the process of prototyping, and the impact of 3D printing on production. Ben also talks about his journey into 3D printing, starting with his graduate studies and the assembly of a MakerBot. The video then shifts to a segment on northern walking stick insects, highlighting their camouflage abilities, behavior, and ecological impact as invasive species.
