Flexible 80a vs. ApplyLabWork "Robust Champagne"


#1

Has anyone done a comparison between Flexible 80a resin and Apply Lab Work’s “Robust Champagne”?

Their brochures make the resins look pretty similar, but I have not done a direct comparison. I might be able to do one in a few weeks.


#2

ApplyLabWork’s “Robust Champagne” is an increment in stiffness from Flexible 80a. I’ll make a few more prints for comparison. While Flexible 80a feels like rubber o-ring material (PTFE, neoprene), “Robust Champagne” feels maybe twice as stiff, and it has a cleaner surface finish on printing, maybe better compared to the kinds of polycarbonates they use for things like sunglasses.

Robust Champagne at 40c behaves similarly to Flexible 80a at 20c. i.e. at normal room temperatures Robust feels more like the old transparent blue “Tough”. But as the temperature increases, it becomes relatively flexible.

Robust Champagne is sandable at room temperature. Flexible 80a on the other hand is rather difficult to sand at room temperature.

This is for Form2 OpenMode, right?


#4

I was originally trying it as a Flexible 80a substitute on the Form 3. It prints well. That said, it’s not really a comparable to Flexible 80a. But it’s a great material to print in, if you want something that has just a bit of give, i.e. is droppable.


#5

I mean, then you just use F80A printing parameters with this ALW resin on your Form3?


#6

I use standard black V4 profile to print on my F3.
Gray profile should work but I have to many fails after a firmware update of the F3.

These new engeneer ALW resins are incredible good in my opinion.

They let me stay with the Form3 - was just thinking about dropping it.


#7

I think Applylabwork suggests using grey, but yes the F80A parameters appear to work just fine. I think the F80A parameters are a little on the conservative side – especially when it comes to the defaults in PreForm. I imagine F80A might be more suited to black or clear parameters but I have not tried these yet.

From their demo videos Spring Pink looks closer to 50A, and Champagn looks like Durable in terms of functionality? I may have to buy a liter of each because, if my hunch is correct, you could probably blend them to make both an 80A-like and something like the 90-95A Durable-80A/50A blend I mostly tend to print in. Neat!
