I put my print in a UV chamber after remove the support materials, it came out really good!

Maybe the wall thickness need to be considered for this type of material.
I noticed you printed the part flat, instead of at least 20 degrees (as recommended). Did the peel have any problems that you noticed? The bottom of the part looks very close to the support. Did you have trouble getting it off?
I have been printing the 1st pebble watchband last week.

Try post-curing it underwater for 15-20minutes.
Don’ t let your part too long in 99% IPA, remember it’s only to remove the uncured liquid around your part.
Polish with sand grip paper (3M 1200+2000) with hot water+oil mineral
Here are the official guidelines from Form, and also some material properties they are reporting.

It is flexible, but it does not stretch much. If you print thin walled parts, expect them to rip or tear with sufficient force. It is not necessary good for small intricately detailed … support removal can be harder with flexible.
Absolutely. I’ve had a few parts rip and tear. It’s documented in their guidelines what settings to try to use to get the best results.
With the Form1+ you only need a minute or two in the UV (if at all). They sourced a stronger laser in the 1+ from my understanding.
I think you mean 91% IPA. I’ve found that 70% is better with the 1+. The agitation is more important than the sit in the bath.
Are people with flexible resin removing supports BEFORE or AFTER UV curing the part? I’m wondering if it’s easier to do post UV cure. Post cure, it seems the flexible has a tendency to rip because you can’t control the minimum support size below the default (1.8?)? This is unlike the regular polymer where it breaks away more cleanly.
I like to remove the support material after uv curing.
It depends.
Most of the time I remove them after. It’s easier to remove as it’s flexible and I don’t like to have IPA/uncured resin on my cutting tools
It came right off the build platform with no problems and I printed it kind of flat and no problems with peeling I love the flexible material.
I will be printing more flexible material and I well keep all of you updated In the meantime if you have chance came over and see my hub. Sunshine prototyping https://www.3dhubs.com/new-orleans/hubs/sunshine-prototyping 1 Cheers
I’ve done a maybe half a dozen projects, and a few dozen prints with it now.
So it distorts potential edges during the peel process? The first print with flexible I did was not oriented, and I definitely saw some “snapping” action during the peel.

Nice one, Cyprien! Would you share your pimped pebble watch with us? 
Ps: Good to see you here
