I saw this video and decided to get a roll to give it a try!

It would be nice to know how it prints, what it smells like and how well it stands up to high temperatures.. Please Nifty come back with your results and comments..

That might be good for my future Mark V1

Once I have a need to use it, I'll report back... but in the interim, here's a lot of data in these videos:

For me 5 mins of video is more than I can bear, I don’t reckon I could go another few !
Thanks but, I will await your results, Johnny 5 is going anywhere for now..

Looks interesting, although I am curious what additives got used to give the material these properties.

I think PLA is great for being basically fermented plants and therefore not being much of a health concern. Reading that this filament is more abrasive compared to regular PLA, and the additives are not being biodegradable makes me question the reasoning for anyone to choose this filament besides curiousity.

In my opinion, PLA is chosen for art, sculptures, maybe some cheap prototyping or biodegradability application. Anything that doesn't fulfill any mechanical or structural role. Need a strong durable part? Go with the filaments that provide these properties by default.

Abrasive filaments eat anything it rubs along and makes me wonder why anyone would pick an abrasive PLA for it's heat resistance compared to a generic PETG or ABS that has similar heat resistance.

Therefore, adding heat resistance to PLA in exchange for it being abrasive, sounds like a net-minus to me.
It seems like a band aid solution to an issue that has had a solution for many years.

On the contrary, because I can see the big benefits this Ht Pla can bring to a project that is exposed to a bit of high heat once in a while, I have dismissed other filaments because they just don’t meet my requirements for several reasons..

The only objections I’m having at the moment is the cost, it’s almost twice the price of standard Pla, and that may rule it out for some bigger projects, I can see myself getting a role shortly dough, but colours are very limited right now..

If it is indeed abrasive the easy solution is to fit a hardened steel nozzle. If it wears the PTFE bowden tubing just replace it. I guess it comes down to how much you need it.

Colorfabb do a HT version of their lightweight PLA which has been well received by those that print 3D R/C models and live in hot climates.

I’m not saying anything against this particular filament, because I haven’t tried it, but in the past I had negative experiences with other self called ground breaking variations of regular PLA. One of them claimed to be as easy to print as PLA and as flexible as TPU. It turned out to retain all the negative properties of both filaments and almost none of the positives. The other is a variation of regular PLA made by Prusa with the name of PLA blend. I like a lot every other Prusa filament I printed, but this one is terrible,. awfully brittle and warps as much as PETG.

Guys, of course you’re free to experiment but, if one thing I’ve learned in these last years, is to absolutely mistrust all youtube videos ( sponsored most of them ) offering the ultimate filament that will replace all the others once and forever.
IMHO if you want UV and good heat endurance get ASA or even PETG. If you want hardness and extra heat resistance get CF filled filaments . If you want the best looking parts, that won't get much heat or UV exposure then get PLA.

To Caesar what belongs to Caesar and to PLA what belongs to PLA.

A man after my own heart, I reckon there’re all bollocks and that’s my opinion, and so are most of the associated forums..

As I said I’m in no hurry to try these HT Pla’s just yet, but come a time I’ll have to use something and I certainly don’t want to deviate from using Pla, because it’s so easy to print and works 99% of the time with no problems.. Just wish I could get more colours other than black and white..
