Welcome to the SeeMeCNC Community

Not meant to be a product pitch, but I really like this line of epoxy, and they always have great instructional tips.

The pdf on repairing an ABS canoe hull is very interesting.

Check out BJB. They've got stuff designed specifically for 3D printing filaments....

Oh, and they're SUPER helpful if you call and have questions.

The infiltrant epoxy they have is amazing.
