Hello guys, recently a problem occured, where I wasn't able to find replacement parts for my custom made fence. Lately I started searching for the on demand metal producers, as the price is not that much bigger, and shipping is quite fast. The shop where i bought it doesn't work anymore and I cannot find any of the suppliers online. I found out about colibrisodm, which processes metal parts based on your demand even at low quantities and their AI helps to draw the part without engineering degree, but is there any other viable alternatives?

Not enough information. Most important, are you talking of replacing castings in your "custom made fence"? Or are you talking of forged pieces that need to be replaced? Two different worlds. 

Ditto anvil, that's just not enough information for a meaningful answer. Pictures would help too.

Welcome from the Ozark mountains. Along with pictures knowing where in the world you are located will also help.
