I am wondering if making an hermetic box is feasible using 3D printer. The box would be a cube with a front face removable, with screw and sealing joint to close it.
I searched for different materials, however, none talks about hermiticity. (However, I found a product that seems to improve water resistance of 3D printed items here, which might be a starting point)
Does anyone have experienced to make hermetic things ? I am specially interested in carbon fiber reinforced materials.
I believe this can be achieved using o-rings. That's what they use for scuba diving lights. The component doesn't need to be circular, but the o-ring needs to be slightly smaller than the component so that it is held in place via tension. Additionally, you'll want to create a groove for the o-ring to set it in and make sure that the o-ring protrudes slightly so that it applies pressure and creates a tiny amount of friction when it's coupled with its counterpart. Apply some type of lubricant to prevent the o-ring from sliding out of place and to keep it from drying out and cracking.
