Work in progress- have not fired it up yet!!!
This is an attempt to print a circuit board for an arduino micro controller using Proto Pasta's conductive PLA.
I have uploaded all the design files if someone wants to make a true 2-color version (I cheated mine)
I'm still in the proof of concept/prototype stages but wanted to post the traces for others to try out, let me know if you are successful! Good luck!
proto pasta conductive pla
I don't have a 2 color printer (yet), so I printed the plate in regular PLA, then offset my Z 2mm (thickness of plate) and printed the board right on top of the plate.
tweaked the holes a little with a heated drill bit. Check out Adafruit.com and sparkfun.com for electronics. Here is a helpful link for wiring https://www.arduino.cc/en/main/standalone
1 Atmega 328
1 7805 Voltage regulator
2 220 Ohm resistors
1 10k Ohm resistor
2 10 uF capacitors
16 MHz clock crystal
2 22 pF capacitors
1 momentary switch
This is based on a design I did back in 2013 and tried to etch on a 2-sided copper board (unsuccessful, couldn't solder that tiny), fingers crossed it will print.
