Addative manufactering (welding) has the advantage of working towards a critical mass. Where as subtractive requires getting even closer to it then moving away from it, as you make the desired part.
- danbruc 3y agoInteresting point but would that really be relevant? If you have a hollow pit or one with an initiator in the center, you will be making two half-spheres, so you will be far away from the critical mass. And even if you are making a solid pit, I would have assumed that you are quite a bit away from the critical mass without neutron reflectors and the compression from the detonation.
- icegreentea2 3y agoI think you'd want to weld the two half spheres together to give a more consistent mechanical fit to help with your implosion efficiency.
