We have both an Ultimaker 3+ and Form2s at our work. We are often printing functional prototyping stuff that needs to be strong with good accuracy. A recent example would be some pulley gears. We printed the small motor pulley on the Form2 in tough and the much larger final-drive pulley on the ultimaker in ABS. I can’t comment on the life span of these gears as we haven’t hammered the pulleys yet, but they both seem like they will last pretty well for a prototype.
Tough and durable are the 2 engineering resins we really like for functional prototyping.
You won’t have delamination issues with the SLA prints and will have much better accuracy over small details. Part orientation and (usually) customising the support structure are needed to make sure your parts function as best as possible.
