We have been using it. It seems to hold its dimensions very well (when compared to the tough resin), and also has a good amount of flex to it when printed in thinner sections. I would say it works pretty much as advertised, very similar to polypropylene. I have been able to break a few pieces, but only after flexing them way beyond where I would expect them to bend. Overall, a good experience so far. We got one of the sample assemblies as well…pretty cool!
