What is the best method to cut small resin parts from a parts tree? Will a #11 X Acto blade work or should I use something else?
CV Sayler
I bought a hot knife, which uses a #11 blade, for this exact purpose. I haven’t actually used it yet, but I expect it will be very helpful.
Cheers,

I suggest a JLC saw, that’s a brand name but they are sold under other names as well. They are replaceable blades as thin as an old fashioned razor blade that are attached to a handle with a plate and screws. Fine teeth on one side and extremely fine teeth on the other. For bigger parts I take them over to my band saw.

Razor saw is good, just be careful with cutting/grinding/sawing, that dust is poisonous.
Assuming you are talking about 3D printed resin parts, I would warn you about using x-acto blades.
No matter how sharp your blade is you are stillpretty much just pushing against the support, which can break the part if it is small enough. It is best to use a very fine saw so you can remove material as you go.
Here’s FSM’s primer for working with resin, including cutting pour plugs.

With an X-Acto or scalpel blade, you don’t cut so much as scribe along the seam or cut line, along the block, till the piece separates.
The fine razor saws others have mentioned are very good for this job, though. They create as small a kerf as possible.
