短期內5-10年內不一定是好投資方向,和你之前的Hydrogen Fuel Cell system 一樣:
政府做做R&D, 科研補貼還可以, PE 投大錢想要有多大回報,請三思~~

1. Currently, 3D printing is good for for fast prototyping, saving tooling cost,
2. For serious structural parts, for high-speed rotational components -- no commericial use.
3. Metal 3D printing has a lot of issues to solve.
What you put out as "proof" was like -- early phase work, NASA readiness level 3, 5 at best.
Spending $1B, saved $70K :-- ) and still not fully proved.
For printing kitech tools, toys, 3D printer could be perfect :), BUT too expensive to be commercial viable??
For militatry use- weapons, 3D manufacturing/printing maybe ok, because the life time is a few minutes max, and cost is not an issue -- heard about $1000 coffee mug, correct? 3D printed Mug would be very cool, indeed, 3D printer would be good for coffee cups :)
For commericial use -- like a jet engine/gas turbine power system, life requirement for system could be 40K - 80 K hours, which is continuously running (24 x 7) for 5 years-10 years; life of components would be ~ 20K hours.
You really think the current 3D printer will generate that kind of parts -- precision/tolerance, heat treatment, etc..
3D printers & raw material supplies?
