Prints Porous.

I noticed that after soaking some CPE prints in water to remove PVA they are taking water into the infill. I only really noticed when I blew them off with compressed air. Is this normal?

It has nothing do to with CPE and can happen with all materials. Due to the printing process you cannot be 100% sure that you have a watertight object. You can use more perimeters, print slower and hotter to ensure you get a good layer bonding. But a very small area of i.e. under extrusion can be enough to be not watertight.

Thank's I thought that might be the case. Prints seem solid enough so I'll not be too concerned about it.

Often these are only very small openings which are almost invisible to the naked eye.
