What does a barrel of aluminum welding wire cost?
I work for Arconic and we actually have 3D printers that can 3D print aluminum and titanium alloys. I really wish I could utilize some of the companies capabilities and technology. A lot of things we have, and our capabilities would be a game changer in the Diesel Motorsports world.

Thank you Mr. Flanery for the response and the link. Some form of valve control like this certainly does wonders for valve train losses. I will certainly research it more.

What would this technology do for a P7100 injection pump. Instead of having the conventional camshaft?

I'm all for any way to get this thing put together. I'd like to watch some of the priting/welding in action.

Iím not entirely sure. The printers actually use lasers to melt the metal alloy in powdered form while itís printing. Unfortunately a lot of this is in the research and development stage. I do know all the nascar blocks get sent to our thermotech operation which they put them in large heat treat pressure vessels and expose them to heat and pressures for some alloys up to 26,000psi for long periods of time to change the molecular grain structure of the alloy to make it stronger. We also offer high heat resistant coating for jet turbine blades that I could see doing exceptionally well on the tops of pistons. I should of looked into it more prior to building my motor but I think in order for them to something they want a contract and multiple orders due to the metallurgy and engineering involved in the process.

This was my understanding, that laser sintered parts have to undergo post treat to be usable.

There are companies that lease the equipment. They were involved in scandals with firearms parts.

There are places that you email your CAD file and your 3D printed part comes back. No need to spend all the money buying the equipment. I have had parts printed.

That is correct. They must be heat treated. All of our cast or forged parts under go heat treating.

Curious, 26k psi is a tremendous amount of pressure to produce. Additionally, the vessel to contain those pressures and temperatures must be huge.

Would you know how the pressure is generated?
