for nasa wants to head to mars and use a 3 d printer to print whatever they might need. 3 d printing is used in all types of sectors. blueprints for 3, they printed guns, can be found online, even meet as being freshly printed. some ideas are fascinating, others a bit worrying, but what about the ecological footprint? how sustainable is 3 d printing? actually, that's our topic on shift today. ah . in 3 d printing a process called additive manufacturing as used. this means you at material layer by layer until the object is fully printed. for this many materials can be used to plastic metal and even chocolate. researchers are already experimenting with using human cells to prince skin or organs. there are also many 3 d printed houses, just like these environmentally friendly. what's the u. s. based startup?

azure 3 d. prince tiny houses made for cycled plastic. more than 60 percent of the raw material comes from recycled plastic bottles and food packaging. after house design is complete, it takes just 24 hours to print the buildings, outer structure. i sure says it's method of constructing houses. it's 70 percent faster, and 30 percent cheaper than conventional building methods. 3 d printing is supposed to be more environmentally friendly. the construction industry is the largest consumer, if raw material and responsible for about a 3rd global c o 2 emissions. the processes themselves are energy intensive, and not much of 3 use for recycled. 3 d printing could change this as materials are considered more resource friendly. lady printing is known well more formally as addison action, which obviously means instead of taking away you,

adding one layer by one lay i one layer that is obviously some waste. if you have pent failures, other things, but it really reduces it because instead of getting rid of the material, you are just building up what you do. in addition, less storage space is needed because the building materials are put together right on site. that can be incredibly useful, especially in crisis situation. there is a huge place for 3 d printing and construction, especially in disaster stricken areas. are those with high homeless populations, sudden influx of population, from refugees or otherwise. there's a huge, huge opportunity here, especially using local materials to create new or sustainable concrete and get things happening really quickly. building houses quickly and using recycled materials. sounds pretty great, but that alone won't solve our plastic waste problem. after all, 91 percent of our plastic isn't being recycled,

meaning it can't be used in construction. the 3 d printing sector could change this and his waste for good. did the guy not even real, we have to do on, on the marquee as now? we are grading, imagine that from the 3 percent to the 7 percent of the cost of each product we buy is the packaging, and then we throw it every day. you throw millions of my theory, us every one. and we thing that these, my ideas are the vase of anyway, the packaging is the only thing being salvaged. food waste is to one example, muscle shells. they normally end up in the trash. but developers from spain are testing out ways to make them into new products. using 3 d printing, ah, we as a society we will use a lot of ways went into the ocean like a leg, muscles muzzle shells. so we, these, we great powder and then with these by that we can transform it into

a gain of ceramic. what we do is we 3 the brand, these powder with some other materials, and then we can use these at the, in as a sort of face was an object that can be useful for. the researchers are experimenting with egg, a nutshell as well. sustainability and 3 d printing may start with the materials, but that's not where it is. the nobility is such a huge topic that we know we need to take a lot into account in the fall and to and lifecycle. so understanding the right materials and using the right amount of them being able to create lighter weight, more complex parts went black material, as well as using the least amount of power possible and shortening the carbon footprint by shortening the logistic. if the building materials don't need to be transported halfway across the world, that could lower our c o 2 emissions. of course, ideally we would be re purposing our trash to. the construction industry is

experimenting with natural resources that are available locally. one example is clay. this chicken cook, if made of clay a very traditional material, but it was built using modern technology. 3 d printing. still costs were kept low since clay is available locally. it's much cheaper than conventional breaks or cement. making use of local materials is important, especially now in an energy crisis that hungarian christian cora. we only use those at the small gosh, last so the costs of modern building materials are rising so much annual that the choice will be clear that only corte my the magnesium. so if you have to decide between, i usually walks already in the ground next to you a lot will spinning endless amounts of money to manufacture and ship the material valley than what are you going to lean towards building that claim by a wells fargo bill anthony esther may lego, and that's not just cheaper. it's more environmentally friendly to hardly any

transport is involved. and the construction process uses much less energy. if you're like, what makes loan so great for 3 d printing. this material doesn't have to be manufactured, so you don't need to invest a lot of money in time. unlike brake switch me to be good or cement which needs to reach 16021800 degrees celsius or production process. gosh, here you take up the local soil, mix it with clay and hay and then the parental can begin not mutual, not talk as we're my genuine patasha ish. it's as long as the technology is still in the development phase. but in 3 years christian gora intends to print a real house out of clay, non traditional craftsmanship and modern technology. i think it's a perfect match. another project in development is construction droughts, essentially flying 3 d printers. these could replace energy intensive, heavy machinery and take on more dangerous task at great heights. this could make

the construction sector is safer and more environmentally friendly. this may be the future of construction. researchers from the imperial college london have developed a fleet of flying 3 d printers. our approach here was to think of multiple agencies broke together and, and liberate the 3 d printing process from the closed build envelope of ground based printouts. because of that, there are scalable, we can have thousands of agents eventually and they can parallel eyes the manufacturing process. this would reduce the need for large machinery, which would decrease c o 2 emissions and lower costs. plus the drones could tackle dangerous tasks like working on high buildings. i'm not saying that it might replace all of construction, but even if it touch 5 percent of the construction industry with this, it is already a huge gain and can reduce your to consumption, increase safety, reduce logistics needs, and like this help the sector,

the drones use especially designed, ultra light weight cement. and they completely autonomous construction drones print while scanning drones check that everything is going to plan. the idea comes from nature. it's modeled on how wasps behave, these natural builders work together to build their homes. it's not about copying everything about the nature, it's copying the principle and then building struggling and building robots that benefit from the philosophy of how the natural world operates very robustly in the most killable manner. and then benefiting from the best of technology that we have access to from works of art to custom, fitted prosthetic lengths. 3 d printing is transforming ever id of sectors in the way we eat. the foot market is expected to grow by about 50 percent annually. over the next 5 years. bakeries are using 3 d printers to automate parts of the process or fulfills special orders. and it may look nice, but food out of

a printer that doesn't really sound tasty to me. this company prints meat, but it's not manufactured from animals. it's plant based using ingredients like beans, peas and coconut fat beaches is used to imitate blood. when i want to make my thing and i have a library of a few different slabs, i can choose each one of them and i can adjust that, or i can define the amount of normally the channel or there's an artist and i can start with the start up plans to ramp up production and print up to $500.00 tons of food a month. they're already selling their vegetarian stakes in several european countries. in the past 2 years, we have been working deeply on understanding meet and what makes me so exciting. and we identified a few components that we can recreate from plants and have the same exact in

performance as the tissue of animal me. the products are primarily geared towards people aiming to eat less meat or none at all. we feel world in a decade from now that new meat or meat made from plants is a big part of the meat industry. it replaces a lot of the meat that people consume today. that is bed for the environment and bed for the most. most of the people in the supply chain, i still believe that people will consume high quality, meet forever, coming from animals. and these 2 industries will leave side by side fake, meet production, and germany grows by about 62 percent. between 201920213 d printed field could be a welcome relief for oceans over fishing, threatens to destroy marine habitats and throw it systems out of balance. his start up from austria produces 3 d printed salmon. the various components such as muscle and fat, are recreated using

a range of plant based ingredients. the 3 d printer gives the famine a typical consistency and look while many people will continue eating, fish and meat, others are seeking out alternatives, which is great news for our ocean, the climate, and the environment. so how about having a vague and stake from a 3 d printer for dinner that could reduce our environmental impact according to the ins, food and agriculture organization, nearly 15 percent of harmful emissions come from livestock farming when it comes to protecting the environment. 3 d printing may not be a bad idea. the 3 d printing is real, uniquely positioned to be a more sustainable and less wasteful industry than traditional manufacturing. it's still a young industry, so there are a lot of learning stops. i had to truly optimize in the cheapest potential, but the way that we're seeing it going, i can only believe that this is better for the world from

a sustainability perspective. less waste, lighter objects, and more sustainable materials. 3 d printing is full of potential to make production processes much more energy and resource efficient. it's unbelievable to see all of the things that can be printed these days. what would you like to print and how do you think this technology could be his best? let us know i and see you next time. ah ah, oh, what people have to say matters to us. i am. that's why we listened to their stories. reporter every weekend on d. w. they breathe. ah,

they have body and soul. the houses that dental leaders can't construct far more than just building ah, his ideas, bold and passionate years to be radical. that's a radical mean. go back to the roof. he is the son of jewish holocaust survivors. how lucky that i was able to build pictures, present berlin, because it's very costly. related to me as a person is architecture, is a celebration of democracy and piece it's not building. the biggest thing in the world is the spirit of architect of emotions. architecture is kind of a mystery, believe me, this is trent starts december 25th on d w.
