Raymond Weitekamp has a thick mop of sandy blonde hair, a hybrid between a Beatles mop-top and a Bieber shag, that tightly frames his blue eyes and slightly crooked nose. If you took him for a surfer who’d spent time in a boxing ring, you’d be wrong. At the very least, you might suggest that he is from Southern California. And on that score, you would be right.
But unless you happen to closely follow developments in polymer science, you likely missed Weitekamp’s big discovery — the one on which he founded polySpectra, a startup that is looking to make an indelible mark on 3D printing.
