So I finally cracked dual nozzle tpu prints on the h2d

So it works fine on the left nozzle? Which specific TPU are you using?
I think this is more another example of tinkerers flexing their skill. As an average user i think this would be one of those âit works until it doesnâtâ type deals.
Which hardness are you printing?
If that white is Bambu TPU 90 I gotta say. Amazing in terms of printability, bullcrap in terms of durability. For comparison , same part with BBL TPU white 90, two weeks in the sun and it was brown. Same part with polyflex90 and itâs already two years outside , still white as of bleached. I regretted the money I gave for these couple spools and now I worry about the other colors as well. Definitely wonât buy the white one again though
Yes the white one is BBL90A. I agree, its properties are very bad, doesnt hold up at all in the sun. Actually you can already see it turning yellowish-brownish even if its idle for too long with hot nozzle. Thankfully its the last roll im going through and never again the white one. I also have their other colours/gradients, but havent noticed anything bad (apart from the Orange85A which seems to have been mislabeled, feels more like ~70A but that can be attributed to difference in measurements from brand to brand. Still any machine I have used the Orange, it kinda struggles to extrude as it cant grip properly, which is strange considering that the same machines print TPE80 nonstop all year round) .
But the white⌠ill put it like this. Beautiful to watch being laid down. Horrible after couple days of use.
I suspect BBL contaminates their TPUs too much for âease of printabilityâ which in turn has these âenduranceâ hindrances âŚ
So it being possible, then I could print transparent Blue with Solid Yellow for something I want to be flexible.
Use white 90 from bbl for a surprise âsun activatedâ poo color transition
