I spent a year on electroforming using copper and silver on rubber mandrels.
Not flash
but self supporting layer thicknesses regarding private jewelry manufacture.
Got some
good results but layerl quality like brittleness and softness after silver
soldering
required additives I bought from a specialized company.
There are a number of factors that effect brittleness. As was pointed out in
this discussion, brightners and levelers (which are common in jewelry
manufacturing) can have an effect on mechanical properties. As was discussed
earlier, good mechanical results come from the absence of brightners and
levelers.
An area costing thousands of manhours of testing. Vulcain motor
electroforming is not for amateurs AFAIK.
Perhaps. I'll have to find out for myself.
Also, not everyone needs to learn it. Only a few people need to master it to
make chambers, valves and tanks available (e.g. for sale) to other people. The
cost to electroform some parts can be significantly less than that of machined
or 3D printed parts. The non-labor, non-recurring cost of my chamber is in the
few dollars range. A similar 3D printed combustion chamber would cost close to
or over $1000.
