I'm waiting for somebody to build plastic foundation from a 3D printer. Or better yet, fulled combed frames out of wax. If you can squirt ink, can't you squirt wax?
It will take some experimentation but I am sure it is possible without too much trouble.
One would certainly do best to make the foundation out of your own clean wax.
I have also thought a 3d printer would be useful for making bee escapes, feeders, queen cages,
and beetle traps.
Be nice to test your own trap ideas and make useful beek stuff.
How come I have never seen anyone use 1/2" x 1/8" aluminum angle in the box dadoes to hold the frames up?
I am certainly eager to hear what experienced beeks think of this idea to save box and frame wear and tear.
I have seen the cheap steel pieces for sale for this, but aluminum angles are cheap and easily found.
