I havebeen looking into nndm and baught a small 3% of my portfolio, the company has good potential with earning money from the army.
The only thing that i feel is risky with this company is thr fact that there product is just focused on selling to other companies (lower potential uppside then example KO had back in the day). Still a potential 3-10x depending on how mangment works out and how they market them self to other companies.
Example it would be a hard sell to get apple to buy there machine, im waiting to be impressed with the managments strategi before investing more money/or less.
