Fresh hacks every day
The thought of using a 3D printer to fabricate PCBs is tantalizing and the good news is that it’s a reality. This project shows that it’s possible to use a special printer head to apply traces to an extruded substrate.
This is similar to the point-to-point 3D printer circuits with one big upgrade. Now the traces can be printed … Read the rest
This glowing LED is proof that the experiments [Nvermeer] is doing with conductive ink are working. We’re filing this one as a chemistry hack because you need to hit the lab ahead of time in order to get the conductivity necessary for success. He reports that this technique uses a copper powder suspended in an epoxy intended for spray … Read the rest
[Jordan] likes the flexibility that conductive inks offer when putting together electronic circuits, but says that they are often too expensive to purchase in decent quantities, and that they usually require substrate-damaging temperatures to cure. After reading a UIUC Materials Research Lab article about making conductive ink that anneals at relatively low temperatures, he decided to give it a shot.… Read the rest
