new ideas are often simple connections

we could eliminate those defects.
we could also start using materials
and we could have amazing properties.

as you lower a stage in there,
with an oxygen-impermeable window,
with a traditional window,

Why you should listen
Joseph DeSimone is a scholar, inventor and serial entrepreneur. A longtime professor at UNC-Chapel Hill, he's taken leave to become the CEO at Carbon3D, the Silicon Valley 3D printing company he co-founded in 2013. DeSimone, an innovative polymer chemist, has made breakthrough contributions in fluoropolymer synthesis, colloid science, nano-biomaterials, green chemistry and most recently 3D printing. His company's Continuous Liquid Interface Production (CLIP) suggests a breakthrough way to make 3D parts.
