Proto-Pasta Stainless Steel and Magnetic Iron PLA Filament

Hi all,

I don't know if you saw this, looks interesting, direct response to the bronze and copper fill filaments from colorfabb

Im slightly worried about grinding down the nozzle on these things... I mean if glowfill can wear down a nozzle I can't imagine what stainless powder can do.

I wont use carbon fiber on my new nozzle anymore. I'm pretty sure it is part of the cause I cant print PLA/PHA well anymore.

When doing a cold pull it's so rough and brittle it feels like asphalt.

 

[pm_dude 27]

Its not the only thing for sure and will be looking forward to those new ones if they can compare to bronze and copperfill.

I might have another nozzle just for those type of material.

"Full testing is pending, but the particles are spherical and finely ground. We had that concern with our CFPLA because the carbon is chopped and rough, but have yet to see unnatural wear on our nozzle even after 6 months of exclusive use on our Printrbot Simple Metal. The steel filament is less abrasive than the carbon, but a bit more abrasive than standard PLA.

That being said, when discussing this issue, we've often heard the argument that 3PD nozzles are consumables, like spark plugs or filters in your car, that have to be replaced at a rate consistent with how often you drive, er, print. Not that that is an excuse to market a product that would destroy printers, which we would never do, but over time wear happens no matter what you are printing with.

TL;DR: Full testing is pending, but we don't expect this to be a major issue."

So i guess that's consistent with your carbon fiber woes... Think I'll wait to see on this one...

thanks. This is good

Yes i'm questionning myself too how this will affect the nozzle, because as you mentionned the carbon proto pasta filament is a nozzle killer from what i've heard

 

[pm_dude 27]

I'm curious to if it's possible the print might warp a little while still hot due to the magnetic properties. It might not be enough but there is plenty of metal on the print head of a UM2.

The material itself isn't magnetic, it's just that magnets can stick to it.

 

[pm_dude 27]

Ho! haha. so much for reading the article :oops:

Most magnets would loose their magnetic force at the temps that are present in the hot-end.

It might mean you can magnetize it afterwards, though

I am curious how all this metal filled material is affecting the hot-end. Especially steel and similar metals are a bit harder than the hot-end itself, typically causing a lot of abrasion and wear. I asked Colorfabb about this and they said they did not really test this/had a chance to test this due to time constraints.

We will see, but I would expect a significantly increasing wear with ever harder fill materials.

I read it They are careful not to be too conclusive yet, and of course, it comes from a party that has a huge interest in selling the product.

If it turns out to be what they say, it seems to be not a huge issue.

I dunno... they're saying that nozzles are considered consumables. Which, while valid, is kind of scary to hear from a filament manufacturer concerning wear and tear on the nozzle. There is another thread on here where glowfill has ground down the filament to the point of unusability after a 40 hour print.

I think I'll wait to see how it goes from the brave and experimental folks.

 

[pm_dude 27]

Yep the Carbon fiber PLA was pretty rough on the nozzle

[jonnybischof 60]

Maybe that could be a good use for E3D's stainless steel nozzles
