Please forgive my terrible ‘phone-photography (my camera is on a tripod for time-lapsing my tomatoes) but if you can’t make it out – above is a handful of 3d printed black PLA buttons. Common or garden variety – two hole, 2cm diameter – buttons. They’re not big, and they’re not clever – but they print in under 2 minutes and they don’t melt in the tumble-dryer (I’ve tested them – 3 times). I broke the top button on my favorite pair of combats recently, and it was a few days before my brain finally had that eureka moment! I designed and printed a replacement, sewed it on, all in the time one morning before leaving for work.
This is not a grand story of 3d printing – it’s no breakthrough development – it’s another grain of sand on the beach.
