Razor Hobbies Conductive ABS Filament by RobertDunn Mar 2, 2013

Description

Here at Razor Hobbies we have been working on a conductive filament to be utilized with our 3d printers. The current filament is still a work in progress and still in its testing phases. The filament is a Conductive ABS Filament. In the photo it shows a small circuit board printed with white abs and a small thin layer of Conductive ABS printed on top leading to a Traxxas connector. The conductive filament has been a year in the making. Follow us as we continue to post updates an test with our conductive filament.

can't wait!
In regards to ratio of key ingredients unfortunately we will not divulge.

Compared already though to other conductive filament on the market ours has well surpassed their conductivity. But once we have refined the filament process that will be a big step.
I'll be very interested if you could keep the resistance constants and able to make a measurable quality product. Any hint on the ratio of other substance to ABS would be nice.

We will soon be posting up a small test video within the next month of our conductive filament being tested in a printed circuit.
I'm very keen on testing this as I've had bad experiences with other conductive ABS. Where do I sign up to be notified?
Im there with you on bad experiences. I dont see how some companies can say that their abs is conductive which in reality it may have a very tiny bit of conductivity but you can not benefit from it. Our material on the other hand has enough conductivity to light up led's and a circuits.

We are still doing alot of test as we don't want to be held liable for the material damaging a machine and so forth. Once we release the material to be available for purchase we will let everyone know as well as post it on our facebook page.

Does mechanical stress cause the resistance to change? If is does then a high resistance mix would probably work best to create a form of strain gauge.
On one version yes.
Just uploaded a pic showing an led burn test to show the conductive properties of one version of the 3d printable conductive material. However what this test does not show is the draw backs to this version. Due to its properties we encountered quite a few clogged tips if the composition was not right.
can I buy your conductive ABS?
At this time it is still in its testing phases. And we have had issues with clogged tips in the past. once perfected we will approach that option. Right now its just in its testing phases and we just wanted to make people aware of what we are doing.
I love the concept, and hope to see more experimental models in the future
At 65mm the best that we have achieved so far is 12.1 but that is a improvement over 35.6 that was from our last batch. With each batch we do we are seeing improvement upon further refinements.
Ohm? Kilo, Mega? And what wiresize? Mesured on 3mm filament or printed?
Printed from a 1.75 filament it was tested at 200 ohm. The conductivity tests were only tested on printed parts or traces.
They will probably never get the resistance down to that of copper, but if the resistance changes due to strain, then there is a entire world of sensor applications.
Neat! Any info on resistance (per mm with x mm² )?
