CHALLENGE:
With conductive filaments popping up everywhere, we should be approaching a point where we can actually print some basic electric devices. However The few conductive filaments i have tried have been minimally useful. So here is the challenge. I have made 2 models that should be printable by almost any printer (70mmX70mm print bed required) This model is designed to work with the “filament Swap” 2 material printing technique, so only one print head is required. 2 Models are provided on this page 1 is the sub-straight, the other is the conductor.
The goal is to populate an 4 LEDs and 4 Resistors and get all 4 lights to light. Some key notes. This board is designed to be electroplated, all of the conductors are connected, but there is a groove cut to make it easy to break off the “short”. So my personal plan is to print-Electroplate with copper-break off the board- populate- test.
The challenge is to be:
1:First to have all 4 LEDs light, any technique (without modifying traces)
2: First to electroplate all signals successfully (you can mask and etch but sub straight must be 3d printed. And get the LEDs to light
3: Selectively electroplate only the traces, and get the LEDs to light
4: get the LEDs to light with only filament.
If you are interested Take a shot let me know how it goes in the comment.
@Brook_Drumm I know I said transistors, but i bailed due to layout difficulties.

thats the best part.
