Micronics SLS nylon 3D printer makes electronic circuits
A new desktop SLS nylon 3D printer can make printed electronic circuits with the addition of a powdered catalyst and electroless copper plating bath. The printer is available here: www.kickstarter.com/projects/micronics3d/micron-a-desktop-sls-3d-printer
Applied Science video on SLA printed circuits: ua-cam.com/video/Z228xymQYho/v-deo.html
Favorite copper plating bath recipe:
Heat 250ml deionized water to 60*C in a 300ml beaker, stirring at 350 RPM
Add 2.5g CuSO4*5H2O, wait until dissolved
Add 4.6g EDTA disodium dihydrate, wait until dissolved
Add 0.84ml of 1% Triton-X 100 solution in water
Dissolve 5.8g NaOH in 30ml DI water, stir until clear, then add to bath
Add 4ml Formaldehyde (37% HCHO)
Lower stirring to 100 RPM and begin filtration with 0.5 micron syringe filter and peristaltic pump. No intentional oxygenation or bubbling. Filter return is below surface for minimal splashing.
I experimented a little with PEG and 2 2' Bipyridine, but didn't find them impactful enough to discuss in this video.

Multi-layer reactive foil: no fuel, no oxygen, tons of heat

This unusual sheet metal is made of hundreds of nano scale layers of aluminum and nickel. A spark initiates a self-propagating reaction that creates NiAl compound, and lots of heat!

    @13:40 a few notes that come to mind A. You could use very thin double sided tape at four extremes of plastic and paper backing before placing in printer to reduce stretching of stencil print .you assume the paper will act as a decent friction for rollers . B. 'd imagine you could print 3 index marks on the transparencies which could be accurately aligned with its counter side ,then hole punched along with hole punching the steel sheet in exactly the same way,linking up all transparencies and steel is simply a case of pushing a plastic pin through three holes to locate all steel and transparencies without much displacement error

    Science and engineering need to be made open source so that we can advance them, it's honestly astounding to me that this is proprietary and no university lab has done this already, especially for a process that's so fundamental to electronics in general. I really appreciate how thorough you are, making sure every step is as clear as possible. This seems like a really important resource.

I believe they would sponsor all of your needs in attempting the experimental idea you shared towards the end of the video.

    Have you counted with the delay it takes for the ions to travel from the source to the detector? You state at 15:22, that you change the acceleration voltage to differentiate between the different atomic weights. You use an AC voltage, but don't mention the frequency of that voltage. At 16:23 you mention that that AC voltage drives the X-position of the oscilloscope. When the correct voltage is reached, the atoms have the correct speed to reach the detector. But the ions take time to travel from the source to the detector. That means that when the correct voltage is reached in an up-going phase, it will be higher by the time the ions reach the detector. When the voltage is reached in a down-going phase, it will be lower when the ion reaches the detector. That may explain why you see two peaks for the same atoms, one at a higher and one at a lower voltage.
