The Markforged interested me. And I have been waiting for the Carbon3D since I first saw them start up the press for the tech. But none of them appeal for me at the prices available right now.
In the comments someone mentions the Raise3D. That is one huge printer. But suffers the same setback… if I am going to invest that heavily, I want something considerably better for the end product.
A nice little sub $500 PLA printer, and then a home built aluminum foundry is a quick way to get serviceable parts cheaply. And for anyone doing things so very often that these price points make sense against the effort of mold and cast approaches… a full size CNC seems a better move than the printers.
I am sure I would sing a different story if I had one on hand. But that would mean removing the price as a factor, and really that is the only issue I have with them. Not personally worth what it takes for me just yet.
