this is what happened in janine is particularly because of, of the wording gall got it. i'll have to ended there. a journalist has an blue shirt and i'm on many, many thanks. you're watching dw news from berlin, coming up l tech show shift, looks at whether the 3 d printing is more sustainable than traditional ways of making products cents after the break. i'm like looking more news at the top of the next one small steps for a robot vacuum. one giant leap for exploiting the ocean slow cutting edge technology is looking at the potential of deep sea mining. but this time, the research team will study the possible risk funds in order to minimize the we have an opportunity to get to it right before we start environmental activists

of skeptical is this true nature conservation on the green washing rule bill billions to be made out to pub documentary, deep sea greed stats, december 7th, on dw, the nozzler wants to head to mars and use a 3 d printer to print whatever they might need through the printing is used in all types of sectors. blueprints for 3, they printed guns, can be found online, even neat 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 shift today. the in the 3 d printing, a process called additive manufacturing is used. this means you add material layer

by layer until the optic is fully printed. for this many materials can be used plastic metal and even chocolate. researchers are already experimenting with using human cells to print, skin or oregon's. there are also many 3 d printed houses. just like these environmentally friendly wants. us space to start up pleasure. 3 d prints. tiny house is made of recycled 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 out or 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 of raw materials and

responsible for about a 3rd global p, o 2 emission processes themselves or energy intensive, and not much a 3 used or recycled. 3 d printing could change this as materials are considered more resource friendly. the printing is known more formally as additive manufacturing, which obviously means instead of taking away you, adding one layer by one layer by one layer. that is obviously some waste, if you have pin failures or other things. but it really reduces it because instead of getting rid of the material, you would just building up what you do in addition to less storage space as needed . because the building materials are put together right on sites that can be incredibly useful, especially in crisis situations. there is a huge place for reading, printing, and construction, especially in disaster stricken areas. are those with high homeless populations, some influx of the 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 plastics isn't being recycled, meaning it can be used in construction. the 3 d printing sector could change this and use ways for good. so they're kind of the same view we have to do on, on that my day as now we have reading. imagine that from the 3 percent of the 7 percent of the cost of each product we buy is the packaging. and then we throw in every day you throw millions of my tvs, everyone. and we've seen that these ideas are the base of a new window. packaging uses, the only thing being self, it's food waste is to one example muscle cells. they normally end up in the trash, but developers from spain of testing out ways to make them to new products. so

using 3 d printing the we as, as id with the use, i need a lot of ways related to the ocean, like a, like muscles. most of the shows, so we these, we create a file there and then we just by that we can transform it into a guy. no, sir. i mean, when we do is we do, we need print this file there with some all the materials. and then we can use these at the end as a sort of phase or as an object that can be useful for the researches or experimenting with a can not show up as well. sustainability and 3 d printing may start with the materials, but that's not there. in the university is such a huge topic that we know we need to take a lot of them to account in the fall and to ends life cycle. 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 um and shortening the carbon footprint by shortening the logistic, just 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 coup, it's 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. so 10 gary and christian cor. well, the, the small gosh, last. so the costs of modern building material, the rising so much that the choice will be clear that on recorded might magnesium.

so if you have to decide between a, usually lots already in the ground next to you will spending endless amounts of money to manufacture and ship the material. now the thing was that you're going to lean towards building that claim by a way for you, the length and this stuff may have like a and so it's not just cheaper, it's more environmentally friendly to hardly any transport is involved. and the construction process is much less energy you'll via what makes logan 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 totally unlike brake. switch them out to be fluid cement which sending us to reach 16021800 degrees celsius or production price. s p. i show here you take up the local soil mix it with plain. hey amanda parental can begin not showing up book as of a new fashion. it doesn't like the technology is still in the development phase. but in 3 years christian gora intends to print a real house out of clay,

traditional craftsmanship and modern technology. i think it's a perfect match to another project and development is construction drones. essentially flying 3 d printers. these could replace energy intensive, heavy machinery and take a more dangerous test at great heights. this could make the construction sector safer and more environmentally friendly. this may be the future of construction researches from the imperial college london have developed a fleet of flying 3 d printers. our approach here was to think of multiple agents that worked together and a deliberate. that's where the printing process from the close build envelope of ground based print search. because of that, they are a scalable. you can have thousands of agents eventually and they can par little lies the manufacturing process. this would reduce the need for loss machinery, which would decrease c o 2 emissions and lower costs plus the drones could tackle

dangerous tasks like working on high building. i'm not saying that if my to replace all of the construction but even if you touch 5 percent of the construction industry with this, it is already a huge game and can reduce your to consumption, increase safety, reduce logistics needs. and like this help, the 2nd, the drones use a specially designed, ultra light weight cement. and they completely autonomous construction turns print well scanning drugs check that everything is going to plan. the idea comes from nature. it's modeled on how we have these natural build is work together to build their homes. it's not about copying everything about the nature. it's causing the principle and then buildings trust and building robots that benefits from the, the fee laws, a fee of how the natural world operates very robustly and scalable manner. and then benefiting from the best of technology that'd be, have access to from works of art to custom,

fitted prosthetic lens. 3 d printing is transforming a variety of sectors. even the way we each, the footprint the 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 taste it to me. this company prints meat, but it's not manufactured from animals. it's plant based using ingredients like beans, peas, and coconut that features if used to imitate floods. when i want to start at plants 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've been working deeply on understanding me and what makes me so exciting. and we identified a few components that we can recreate from plants and have the same exact thing performance as the tissue of animal meat. products are primarily geared towards people aiming to use less meat or not at all. we see a word in a decade from now that new me or meet me from plants is a big part of the meat industry. it replaces lots of the meat that people to consume today that these 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 means forever coming from animals. and these 2 industries, we leave side by side, fake me production in germany, gro was by about 62 percent between 201920213 d printed food, could be

a welcome relief for our oceans. over fishing threatens to destroy marine habitats and throw each 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 band based ingredients. the 3 d printer, dips the salmon, it's 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 climate and the environment. so how about having a big and stake from a 3 d printer for dinner that could reduce our environmental impact according to the food and agriculture organization, nearly 15 percent of harmful emissions come from lifestyle farming. when it comes to protecting the environment, freely printing may not be

a bad idea. the 3 d printing is really uniquely positions 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 steps ahead 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 or less waste, lighter optics, 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 by and see you next time. the
