When it comes to transistor construction, it’s a pain in the @#$!, to say the least. You have to plot out your design with CAD software and use other specialized equipment to fabricate it and hopefully it works. But what if there was an easier way to make one, let’s say with a 3D printer perhaps? As it turns out a couple of guy’s called Mr. Kim and John Sarik have used the ever versatile Makerbot to print out their own transistor design. Not only that, they have uploaded their plans and program to facilitate your own design. The secret they used to accomplish this was to use silver in the ink cartridge, that’s the easy step, the rest of the process isn’t so easy but a complete diagram of the steps they have used can be found here: http://mrkimrobotics.com/src/MrKim_Sarik_Printable_Transistors_part1-v1.3.pdf. If this idea and accomplishment can be simplified the world of the mad scientist would have no boundaries.
