Hi Padua,
I’ve only printed the Tough with the lowest resolution setting (I think it’s 1mm?). The detail is fine but you can see some build lines (depending on print orientation and part geometry of course) but this is really no different than how it would look printing on the lowest resolution with the standard materials. Both of which the lines can be easily removed by light sanding in post. That being said the detail is certainly there as it prints fine threads without issue and I’m able to create seals with the part. You can see my test with air and water @ 195 PSI in this thread.
