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.
