[AT] reproduction parts

[Spencer Yost]

I have a Lulzbot  Taz6  3-D printer. It’s a fairly nice 3-D printer, and I have experimented a lot with it(won it at a professional raffle).  As Steve says choices of flexible materials are limited and expensive and are not generally “seal-like”.

I did make a part for a magneto for Brice. Not sure if he ever used it.  He needed something non-conductive and otherwise made out of unobtanium so 3d printing fit the bill.

Right now I see the most common advantage is for making molds for casts, prototypes for parts that will ultimately be manufactured using other materials and processes,  and dinosaurs for your grandson :-)

The option of 3D printing, when appropriate, is probably going to be "cost-effective" (might not look that way to the consumer)  if you need a very small number, versus any other strategy where you need serious investment in some kind of mold/tooling.  On a related note, I have heard that Jay Leno has gotten into 3D printing rather seriously, and now can make nearly any part for any antique car that is being restored in his shop.  While there is such a thing as 3D printing of metals, that technology is still young and wildly expensive and focused largely on exotic materials.  But you can make so-called "patterns" with 3D plastic or wax printing, and make casting molds from the patterns, and make cast metal parts quite easily.

>> John deere had an internal story about doing this a few years ago. As I recall a part that would have been $20 in quantity costs $450 by 3d printing and the profit is less. Still for a one off part it is the easiest option. The 20 dollar part needs an expensive mold that was lost years ago.
