The foodtech startup Revo Foods in September became the first company to sell 3D-printed vegan salmon filets in select grocery stores in Vienna, Austria, and opened an online shop that ships the product to most European countries this month.

"It flakes very nicely into layers just like salmon," Robin Simsa, the CEO of Revo Foods, told Insider. "It also has a similar taste, but like any meat alternative, it's not 100% the same."
