The concept of 3D printing, also known as additive manufacturing, initially surfaced in the 1980s, thanks largely to the innovative work of engineer Chuck Hull. Hull invented a process called 'stereolithography', or SLA, a method that allowed for the creation of 3D models layer by layer, literally bringing ideas to life. It was a revolutionary breakthrough that sparked the beginning of the 3D printing era.

Occupancy sensors are quickly becoming a regulatory requirement in many commercial spaces, thanks to evolving energy codes seeking to wring out kilowatt-hours of energy savings anywhere it’s possible.

They look a lot like a whiffle ball – and sound like one, too – but that thwok, thwok, thwok sound now resounding through cities and suburbs, alike, is probably coming from a pickleball ball, the centerpiece of a sport soon to be coming to a court near you (in the unlikely case that it hasn’t already), and possibly even to an Olympic arena, if proponents have their way.
