Any way to cast pic related without spending crazy bucks?

Sinter it.

The item in your picture was almost certainly not cast.

By Pic related I meant titanium. Not the impeller.

You can only pick one.

Keep an eye out for vacuum furnaces. They are a thing and exactly what you need for titanium. A used one will shave down your cost.
Alternately, if you can find a large vacuum chamber and an induction furnace, I could see a way to jury-rig it into something that might work, though probably sketchy as fuck.

I thought curie point of Ti lies below it's melting point so Induction furnace won't work as good.
I was thinking of using High amperage current in an argon filled enclosure, But I do have to take it out to pour it in the mold.

please don't do this

But titanium isn't magnetic. Also >>1248476.

What are you even trying to do?

>> No.1248487

Just machine it

>> No.1248488

>>1248476
I stated that as problem. Did not imply I was gonna expose molten titanium to air.

>>1248484
I have large amount of titanium turnings that I want to cast it to simple shapes.

Put a coating of pre-mixed bleach, white viniger and put a copper penny in to activate it

Titanium is already highly reactive. It doesn't need anything to activate it. Nice b8.

Only correct answer.

You'd be a lot better off buying a piece of titanium and machining it into your final shape.

Though titanium is a meme unless you work in aerospace and maybe a few other niche uses. Expensive as hell and usually has a buy-to-fly ratio of 8:1.

Only way is to use a vacuum or inert shielding gas and melt down using induction furnace with magnetic levitation of the melt.

Obviously, first off you need to give up.
