Folding complex stainless sheets manually

There can be complex shapes such as injection hoppers which should be done from stainless.

To get around expensive press-brake operations but also expensive TIG welders, you can design the laser-cut part with cut-outs to make folding with a vise or hand easier.

1mm is the minimum for most stick and MIG welders. Cutting out the fold line with an angle-grinder makes this process a lot easier.
