is our technology show shift? looking at the sustainability of 3 d printing is more news available on our website, d, w dot com and on twitter and instagram. asti, w, news, a, michael oke, who in berlin. thanks so much for watching. alive and on demand. mm comcast. and language courses, video and audio. any time, anywhere that d w media center. the world cup

in guitar. i feel in 14 to fulton version in 40 because we are here for you with reports and background information about the portfolio figures. told them everything you need about the 2022 world cup on d w. nasa, ones to had 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 add 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 humans cells to print skin or organs. there are also many 3 d printed houses, just like these environmentally friendly once. the u. s. based startup azure 3 d prints, tiny houses made of recycled plastic. more than 60 percent of the raw material comes from recycled plastic bottles and food packaging. after a 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 method. 3 d printing is supposed to be more environmentally friendly. the construction industry is the largest consumer of raw material and responsible for about a 3rd global c o 2 emissions. the processes themselves are energy intensive, and not much of 3 used or recycled. 3 d printing could change this as materials are considered more resource friendly. lady printing is known well more formally as additive manufacturing, which obviously means instead of taking away, you're adding one layer by one lay. i one layer, that is obviously some waste of you have cont, failures other things. but it really reduces it because instead of getting rid of the material, you are just building up what you mean. 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 in flexes 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 mit as now we are grading you machine 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 think that these,

my ideas are the vase of any window. packaging is the only thing being salvaged. food waste is to one example, muscle shoals. they normally end up in the trash 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, like muscles muzzle shells. so we, these, we great powder and then we 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 or as an object that can be useful for the researchers are experimenting with egg and not show as well. sustainability and 3 d printing may start with the materials, but that's not where 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 with less 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 half way 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 coop is 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 says hungarian christian gora, we only have those at the small gosh, last. so the costs of modern building materials are rising so much annual that the choice will be clear on the quality my, the magnesium. so if you have to decide between a usually what's already in the ground next to you lock 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 esta may have like a 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 with cement which needs to reach 16021800 degrees celsius or production processed the ash oh. here you dig

up the local soil. mix it with clay and hay and then the parental can begin not mutual, not talk as ver, my genuine patasha. 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 get replaced energy intensive, heavy machinery, and take on more dangerous task at great heights. this can 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 agents had worked 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're 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 is coping the principal and then building struggling

and building robots that benefit from the philosophy of how the natural world operates very robustly in a scalable 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 righty 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 bass using ingredients like beans, peas and coconut fat beaches is used to imitate blood. when i want to make like a. 5 library of a few different slabs. i can choose each one of them and they can adjust that. of

course, i can define the amount of marble in channel fast or they fill in august. 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 steaks in several european countries. in the past 2 years, we've been working deeply on understanding it. 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 plant is a big part of the meat industry. it replaces a lot of the meat that people consume today. but his 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 rose 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. 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 ends, food and agriculture organization, nearly 15 percent of harmful emissions come from lifestyle 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, a had to truly optimize and 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.
