Here’s wishing y’all a wonderful Christmas, and all the best for 2013! If you’re looking at this page, there’s a good chance you got to it from a QR code on the back of one of the 3D printed Christmas Cards that Erin and I sent out this year, and we thought you might like to know a bit about how it was made!
It was manufactured using an Ultimaker 3D printer which works by melting plastic at about 220ºC (430ºF) and then laying it down in layers about 0.1mm thick – that’s roughly four thousands of an inch. The layers build up on one another to create physical objects, guided by a computer program that works to recreate whatever shapes are programmed into it.
In this case, we designed the card in a 3D modeling package, and then inserted pauses in the print process so that we could swap in different colored plastics, and so build up a multi-color design. It took roughly half an hour to print each card, although this video speeds up the boring bits in the middle. And it has cheesy music! What could be better?
