I've had my Ultimaker 2 for nearly 10 years. A couple of days ago I did the longest running print that I have done. It lasted very nearly 34 hours. Followed shortly after by the second longest print I've done at 30 hours.
The first was a duct for our kitchen extractor fan.
The second is a cosmetic cover to fit in a cupboard to hide the extractor duct.
Both were successful prints.

I've printed a few resin objects and in a couple of different resins.
I want to remind myself of the results. Bear in mind that I am new to resin printing and these are my experiences and opinions.
PARP10
Described by Heygears for "rapid prototyping".
My Experience:
Surface: Smooth and crisp.
Detail: Very good. Sharp corners.
Toughness: I can drop the models on the floor with no sign of damage.
Flex: Negligible. It'll break if bent.
Prep ease: Very easy. No additional thought needed just position and use auto-supports.
Minimum cure time: 5 minutes.
I would use this for: Miniatures, non-stressed components and decorative pieces.

PAU10
Described by Heygears as "ABS-like".
My Experience:
Surface: Slightly soft.
Detail: Moderate. Slight curves on corners.
Toughness: I can drop the models on the floor with no sign of damage.
Flex: Some. Tricky to break. Bends a bit first.
Prep ease: Needs more supports on long thin objects otherwise they flex while printing.
Minimum cure time: 10 minutes.
I would use this for: Component cases and functional parts.

Subjective
The above statements are a bit vague and very subjective. I will adjust them over time as I gain more experience, but they should be viewed only as a rough guide.
Drop Test
My very simple test is to drop the model from about a metre above ground onto a concrete or similar floor. Repeated a couple of times. For most of what I print, I want them to survive careless handling, but I don't need industrial strength.
Curing Times
I use the Heygears cure unit. I find that sending the model to the cure unit is an unnecessary step, especially as I rarely remember to turn on the cure unit in advance. I've sent a couple of test models, to gauge the times, then for most of my prints I manually set a cure time from the dial on the front of the machine.
