Solderless 3D Printing
Another option for 3D printing is when you want to
make a connection without wire, one of those conductive
inks or glues make a great option; you just need a way
to guide the ink. In a previous Filament Friday video on
my You Tube channel, I made a miniature traffic light. I
designed it in Tinkercad and made grooves for conductive
glue (that I found at RadioShack) to lie into. I applied the
conductive glue to the grooves or channels, and then I
added a couple LEDs and a few connection wires at the
bottom. I let the glue dry and I had my circuit.
From there, I could control it from an Arduino on
a breadboard. This was a fun project using 3D printing
to essentially make a custom circuit board. Instead of
removing copper by etching, I just designed the traces as
channels and then added the conductive material.
3D printing can be used to make many different
useful tools. I show a lot of my creations on my You Tube
channel ( FilamentFriday.com) that I create in Tinkercad.
Sometimes its nice to find something I can just print and
use. Thingiverse.com, myminifactory.com, and pinshape.
com are just a few of the sites I like to search for designs.
There is no end to what you can find to print on your 3D
Once you have one, you’ll wonder how you got away
with not having one for so long. NV
