There is no cheap way to make a mould,only less expensive one's!!!!!!!
If it makes you feel any better we have titanium blisks that get forged to shape and them machined to final dimensions. These get used in our jet engines and each blisk costs about $150,000. Occasionally someone screws one up and it gets scrapped
Luckily the factory I work in only deals with blades
