I'm investigating what printer can and hoping would be under $50,000.
I am fairly certain I could print it, although I do quesition how well I could cast it. Im not sure if my cad program will let me make many changes to the assembly, thats why I asked it to be split. Maybe I could do something with it as an stl file but that would be pretty limited as well. I would still like a look at the file to see if it would be possible (one way or another) but my cad skills and cad program arent exactly top notch...
Here is a SBC I printed out from grabcad.com It didnt come out too bad, but not well enough for me to waste the time and money on casting. If I could split up the file to get a slightly better print then I would cast it.
things like removing the cylinder liners and head bolt holes would make it more printer and casting friendly....
Block was printed with the pan rail down and is complete with cylinder sleeves, cooling passages, and oil galleys. Printed on an extrusion based machine (Rostock max)
