Hi. I am interested in casting a cylinder head for a 4 cylinder car in aluminium. (Let's take the issue of this not being a beginner project as read, it's a longer term goal).
It will be pretty much a copy of an existing cast iron head that I will scan using a 3D scanner, clean up and enlarge to allow for shrinkage. The purpose is to reduce weight and improve cooling.
What is the best way to turn this into a mold? If I get it printed on a rapid prototype machine, can they print a material that can be used as in lost-foam casting?
CNC machine it out of foam? It would have to be done in several parts due to the water chambers and ports.
I'm not too concerned if it ends in failure, it will just be an interesting exercise. I'm going to start by casting some replacement trim parts, hammerforms, and so on, and hopefully work my way up.
Thanks |
