Issues in extruder with PLA+Graphene filament  

Re: Issues in extruder with PLA+Graphene filament

I’m not familiar with that filament. Reading on some graphine online, the .4mm nozzle might clog. I have some pla that will do the same thing as what you are seeing if I print below 225c. You might raise the temp and give it a try.

Re: Issues in extruder with PLA+Graphene filament

First off. I think your filament has a problem.
FILOALFA GRAFYLON® 3d is a filament for 3d printing addicted with Graphene Plus

Your filament has an addiction problem. I highly advise you to get that sorted out. Anything with addiction problems will yield sub-part results.

On a more serious level.

The filament sensor does not detect jams yet. Only if filament is present. (that I know of)

I would not worry about that filament as long as you keep it below 230c. I print a 170-210 PLA @ 230 first layer and 225, all others.

I can literally see 80 things being effected by this filament.

1. Purity of PLA
2. Other additives
3. Other additives
4. Colorants.
5. Other additives

Seriously, no two spools of filament are identical. They can get *VERY* close, but not identical.
A spool of Zyltech filament has major moisture issues after just a month, while a spool of Prusa Silver, prints almost as good as new after 3 months.
The extrusion consistency of E-Sun PLA Pro, is fantastic, and I've really not found anything better regarding the "smoothness" of it's extrusion.
Fox Smart, is garbage, extrudes terribly, and is so brittle you would think it was made out of eggshells.
Essentium PLA is SUPER hard/strong. It does NOT feels like plastic, it almost feels like a metal it's so hard... and it's almost as strong.

My point is. That's all PLA.

Re: Issues in extruder with PLA+Graphene filament

Thanks a lot Sean for your exhaustive reply and yes, the Grafylon filament producer is Italian and obviously the translation is awful.
Fortunately my only addiction is beer and is not a problem with my Prusa i3 MK3.
I know there are many things affecting PLA, and even the spool is the same, I think moisture can be one of the worst.

I will try again increasing temperature up to 225°C to close all the tests with this filament

Thanks again

Sean ... could you tell us ... is that Essentium Engineering Grade PLA or their PLA XTR product that you're commenting on?

I get the big 2kg spools off amazon.
It's Engineering Grade.
It is hard to print with, and not the best filamaent I own regarding it's print quality. (honestly it's borderline terrible given it's price for print quality) but their TDS is missing,

Another that I want to try is 3D870. Apparnetly there's only 2-3 companies in North America that sell it, and they want 30$+/kg. You can get it from europe for about 35$ (delivered) as well. (amusingly, the plastic is made in the USA... why all filaments in the USA cost European price + Shipping is so annoying) There' also about 10 companies in Europe that use it.

I've read the 3D870 is the best PLA filament on the market right now for strength+temp. The only exception I think might be Maker Geeks Raptor PLA. (Which I'm not willing to pay for)
