    well.. Yea :)
    Always interested in cheap(er) filaments.
    Thanks.

    edit: FWIW the ProtoPasta stuff is good filament too.

    I have never tried that brand, but ... I have used the gamut of cheap PLA and have yet to have any be absolute crap (with the exception of the small bit of sample blue that Robo initially sent me). Many, many spools later I still use the cheap stuff for normal testing/initial layout stuff.

    I've used justpla and I will warn you that the spool I got was not good. It had several bubbles or knots that caused it to fail printing and get caught up in the extruder. It also was very brittle and I would have to make sure to pull it from the hotend after every print or it would snap within a couple hours of just sitting there in the nozzle. I got it cheap off of Amazon, but that was my experience. Your mileage may very.

    To support what others have already said... I use PLA for prototyping because it's cheap and accurate. However when making the final part I consider the best material for the job. For that robotic arm that is under so much abuse I would say your best choice is Alloy 910 Nylon by Taulman. The image you provided shows that that material would be a good match for it's shape as well. For the part that has to survive high heat and electricity, there are many filaments with low conductivity, but nothing I know has a tg higher than 400f made off a home printer. Is the 400f sustained heat or just burst?

    If PLA don't work then you should always try ABS filaments. I most of the times use Mankati PLA and ABS 3D printer filaments. They give me good results every time.

    There are alot of materials available for 3d printing. You should give some of them a try :) its not just pla and abs anymore.

    Heck it is almost never ABS any more :)

    Too many better choices.

    I would recommend a nylon or polyamide for this application. PLA is great for prototyping but a nylon is definitely going to produce more durable parts.

    I built a set out of Alloy 910 and we have yet to break one! Knock on wood! They actually work a lot better as well because they sort of have a cushion when material handling. And we have not noticed as much wear and tear when compared to PLA.
