Programmable shape drop forge....
show user profile  HANZZ
Anyone have ideas on how such a thing could even work? I had the idea to create a drop forge, where manufacturers could create a shape in just hours, instead of it taking weeks to draw, mold, and finish a set of drop forge dies. Any thoughts?

Drop forging - Hammering hot metal into dies.
Press forging - instead of forcing hot metal into a die with a hammer blow, it is pressed into the die with hydraulic pressure.

So we are talking exclusively drop forging, right?

So the contraption is a bit like this:

If I then start looking for 'interactive shape' all I could find was this:

Would not stand up to pressure + milling a die makes more sense.

Probably misunderstood your question hence this weird tangent reply.

Yeah, my question regarded drop forging exclusively. I'm certain there are no such realities as a programmable shape, at least not yet. Was idly curious if anyone had any thoughts about how it might be approached. Been designing an exosuit with a few ideas that might be patentable, and when I start thinking in original thought it opens a whole can of worms creatively. Thanks for the reply, btw...!

Metal Laser Sintering (DMLS)
Laser Deposition Technology (LDT)

If you can print the die, you might as well print the product (removing the need for a die).

The solution to a problem changes the problem.

Yeah, printing won't give anywhere near the structural integrity of a drop forged steel object. I'd thought of printing already, but rejected it because of this fact. In drop forging, you hammer on the object with multiple tons of force repeatedly in order to get the helter-skelter molecules to align to the general shape of the object you're making. Doing that makes it far tougher than casting, or even weaker, printing.

you could probably do crude shapes with a set of pins that can be re-arranged with different heights. Would probably yield a very crappy form, but the basic shape would probably be ok. -

I know, right? That was my first 'viable' direction, sort of like the map sequence in the original Xmen (I think) with the same effect. Either that, or getting a cad shape, cutting it up into standardized horizontal slices, and having a mill or CNC use different bits to mill out flat areas and rounded areas in each slice, then stacking those slices together to form the halves of the full die. It would take hours to make, maybe a full day, but would be done in a day or so, and wouldn't take weeks like it normally takes to get dies back from the die makers.

How about something with a lot of little inflatebale bladders, which you then fill with ferrofluid and solidify..
Not entirely sure how hard ferrofluid can get.. If anywhere near hard enough for actual hammering.

Terribly boring signature.
