It's not "printed", it's cultured. Not sure about this company's process but the ones I'm familiar with use a method called 'precision fermentation'. It's like regular fermentation but they control exactly what protein is produced by genetically engineering microbes to produce exactly the product that is wanted. You could theoretically do this at home but for now it would be prohibitively expensive. Who knows maybe in the future there will be companies delivering the starter bacteria and then you can feed them your own nutrient solution in your own tank. I doubt that will be a thing any time soon though. No Star Trek type replicator just yet, sadly.
