Italian bioengineer Giuseppe Scionti from Spanish startup Novameat has invented the "world's first" 3D-printed meat-free steak made from vegetable proteins, which mimics the texture of beef. From a report:
Vegan ingredients such as rice, peas and seaweed, which provide the amino acids needed for a healthy diet, are turned into a food paste that is 3D-printed to form a raw, steak-like substance. Despite an abundance of meat-free products already on the market that taste similar to animal meats, Scionti found that these are limited to imitation burgers, chicken nuggets or meatballs. None of the offerings reproduce a piece of "fibrous flesh" such as steak or chicken breast. In an effort to reduce the impact of animal agriculture and to improve people's nutrition, the Milanese researcher set out to create a plant-based alternative to "fleshy" meat products.
2018/11/30: 3D printing still may not be cheap enough to put up a huge fight against traditional mass production, but when it comes to wedding costs, it actually starts to look like a good deal.
2018/09/28: While it is commendable to strive to reduce the ecological footprint of cities some realism is called for. For their provisions and waste disposal, cities need forest, agricultural, marine, and wetland ecosystems on lands many hundred times the area of the city itself.[xxii] If we are serious about feeding the cities more locally, we should look more to the perimeters of the city and to the interplay between cities and their hinterland. It is here that there really is a potential to feed the cities.
Silicon Valley meats Hollywood That is the best description of how we will get food in the future if we would believe the impressive number of food tech start-ups which will produce food without soil or animals. But few of them deliver on their exaggerated promises.
Because of how badly we humans have treated soils and animals it is understandable that people now are looking for other ways of producing food. Under banners of digital ecosystems, open source, individual foods, actionable intelligence, disruptive food systems and digital transformation, there are legions of entrepreneurs (mostly with background in the IT sector) seeking venture capital and researchers looking for grants.
3-D printing of food is expensive, incredibly slow and not capable of making most of the food we like to eat - today. Perhaps it will in the futures. My concern is rather that 3-D printing of food and robocooks seems to be far-fetched solutions to marginal problems, and it certainly has nothing to do with “solving the world’s largest food and farming problems”.
I turn my attention to methods of primary production which are not soil or animal based (I will leave wild foods and fisheries outside of the discussion).
Few people seem to realize that lab-foods also need a feedstock, and the companies marketing the products are mostly silent regarding the raw materials used. To grow maize as a feedstock for ‘artificial’ food or to produce chicken is not so very different. Chicken production, in many parts of the world, is already landless production, a kind of feed converter factory. And it is obvious that you can do a similar thing with fungi or bacteria. It is not obvious, however, that the process will be much more efficient (but possibly more ethically acceptable).
Tissue culture of beef is currently done on a serum extracted from unborn calves and it also involves the use of antibiotics.[v] Other resource demands are rarely documented, so the claims of being resource efficient still needs to be proven.
Though the cultivation of algae using man-made or natural ponds was initially simple, turning it into a viable feedstock has always been problematic. So our industry has always needed a system that could enable higher production levels, lower capital and operating costs, greater biomass density, better environmental control, and above all, industrial scalability.”[vi] Even bio-fuels could be made from algae, but the cost of production is prohibitive and would use enormous areas and water resources. In addition, it is very energy consuming and CO2 emissions caused would be much bigger than for fossil fuels. Therefore, almost all algae entrepreneurs are producing nutritional supplements and other specialty products which have prices two orders of magnitude higher than fuel or staple food.
Much aquaculture today is based on predatory fish, such as salmon, which are fed on undersized caught wild fish, other fish leftovers and fodder from agriculture. There is not a dramatic difference between modern fish farming and broiler production.
For aquaculture to really play a meaningful role in feeding a growing population in a sustainable way, we need systems that integrate aquaculture and farming. Such systems have developed over a long time in Asia where rice, fish and vegetables have been grown in the same system, sometimes also including ducks or pigs. There are also modern versions of such systems under development.
An extreme version of hydroponics are indoor vertical farms in cities. But the fact that it is possible doesn’t mean it is viable on a larger scale, and even less that it will take place in the cities. Vertical hydroponic farms are totally dependent on inputs that will need to be transported in, they are not part of any ecological context in the city, and if they are large, the crops will be put into the normal food distribution networks. In that sense, they are like any other assembly plant. And, like any other assembly plants, they are better located outside of city centres. But the rational for stacking crops on top of each other is gone where land prices are lower.
But it has little relevance for feeding the population, which is underscored by that the commercial application are all about growing baby lettuce, pak choy or herbs, crops which provide almost no food energy or proteins.
those technologies are not integrated into the ecological web of the city, rather the opposite, they need to be sealed off even from the people and the water used mus
2018/09/25: not only are Defense Distributed's sales of gunmaking tools unaffected, but also that the company will continue its battles with a group of attorneys general from more than a dozen states, who have sued Defense Distributed and the State Department to reverse a legal win that would allow the gun rights group and others to post digital blueprints for firearms online.
Without Wilson, Defense Distributed's Sullivan admits, the company's ideological marketing will be tough to replicate. But he insists its message will still get out.
2014/12/08: The implications of such a paradigm shift in manufacturing for environmental sustainability are enormous. ‘Because they only use the exact material required, 3D printers could eliminate waste from traditional manufacturing – in which up to 90% of raw material is discarded’ In addition to realising economies in the use of raw materials, the type of distributed manufacturing undergirded by RepRap-like 3D printing implies a massive reduction in global transportation costs attendant upon the localisation of production (Rifkin 2011). Clearly, large-scale industrial infrastructures and the mass production model itself are no longer needed if people are able to micro-manufacture whatever they need in the comfort of their homes. And that is good for the environment
2016/08/17: People often ask me: is this 3D printing thing actually useful to somebody? My answer: it surely is, for children affected by leukemia!
2013-10-03 : The bottom line is, we can get substantial reductions in energy and CO2 emissions from making things at home,” Pearce said. “And the home manufacturer would be motivated to do the right thing and use less energy, because it costs so much less to make things on a 3D printer than to buy them off the shelf or on the Internet.

As promising as 3D printers seem, their usefulness is still questionable. High costs, safety concerns, patents, and design complexity are all contributing to legitimate skepticism.
The 3D printer is a double-edged sword. It stands to transform technology and society for the better, but we also can't ignore the potential negative consequences.

One thing that 3D printing is particularly good at doing is making things smaller. I'm not just talking about high-resolution 3D printers capable of 3D printing on the nanoscale, although those have certainly done some remarkable things.
When I was growing up, I hated drinking milk, and so had to take these giant, brown, disgusting calcium pills every night with dinner.

3D printing is a rising threat for world trade. According to a new ING report, world trade will be 23% lower in 2060 if the growth of investments in 3D printers continues at the current pace. If investments accelerate domestically printed goods could already wipe out 40% of world imports in 2040.
3D Hubs seems to have developed a new strategy for distributed 3D printing.
