somebody has already dropped off his that title in a row i had of sunday's season close enough. they yes. second was you're watching the news one brand and i am at the mike a junior bang school watching station from one use of the top of the out. the one small step for a robot vacuum, one giant leap for exploiting the ocean floor. cutting edge technology is looking at the potential of d t mining but this time, the research team will study the possible risk in order to minimize the we have an opportunity to to get it right before we move from star

environmental activists. i'll get to code. is this true nature conservation? well, i mean the green washing rule bill billions to be made out to pub documentary, deep sea greed stats, december 7th on dw, the nasa wants to have 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, the printed guns can be found online. even meet as being freshly printed. some ideas are fascinating, others a bit wording. but what about the ecological footprint? how sustainable is 3 d printing? actually, that's our topic. i'm shift today. the in 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. the 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 method. 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 c o. 2 emission to the process as themselves are 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 or 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 10 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 3 d 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 like huge, huge opportunity here,

especially using local materials to create new or sustainable concrete. and get things happening really quickly in 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. does it kind of, uh, the same view we have to do on, on the materials now we have the reading. imagine that from the 3 percent, with a 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 think that these ideas are based of any weakness. packaging uses. the only thing being salvaged. food waste is to one example, muscle shelves. they normally end up in the trash, but developers from spain testing out ways to make them to new products. so using 3

d printing the we as a society with the use, i need a lot of ways related to the ocean, like a like muscles. most of the shelves, so we these, we create a file there and then we just by that we can transform it into a kind of ceramic. 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 seen ability is such a huge topic that we know we need to take a lot into account in the fall and to end life cycle. so understanding the right materials and using the right amount to 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 logistics. 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 play this chicken coop, 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 gora, we are the, the small gosh, last. so the costs of modern building material, the rising so much that the choice will be clear that on the quality 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 material. how do you think you're going to lean towards building that claim by a way for you the length and this stuff may have, like i said, it's not just cheaper. it's more environmentally friendly to hardly any transfer. it is involved in the construction process to use as much less energy you'll via what makes loans 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 because i'm like break. so it's not to be fluent cement which sending to reach 16021800 degrees celts has on the production process. yeah. so yeah, you got the local soil mix it with plain. hey amanda parental can begin knock nissan of elk as of a new fashion. it doesn't like the technology is still in the development phase 5 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 upgrade heights. this can make the construction sector is 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 and 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 realize 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 buildings. i'm not saying that if my to replace all of the construction but even if you touched 5 percent of the construction industry with this, it is already a huge game and can reduce your to consumption, increase safety, reduced logistics needs. and like this help, the 2nd, the drones use a specially designed, ultra light weight cement, and the completely autonomous construction turns. print walls, scanning, drones, 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 the homes. it's not about copying everything about the nature. it's causing the principle and then buildings trust and building robots. the benefits from the, the, the laws of, of how the natural world operates very robustly and then a scalable manner. and then benefiting from the best of technology that'd be, have access to from works of art to custom,

fitted prosthetic limbs. 3 d printing is transforming a variety of sectors. even the way we each, the footprint 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 fat beaches is used to imitate blood. when i went to. 5 the difference that the startup 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 have 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 able to use less meat or not at all. we see a word in a decade from now that new meat or meat made from plants is a big part of the meat industry. it replaces lots of the meat of 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 rose by about 62 percent between 201920213 d printed food could be

a welcome relief for our oceans. over fishing springs to destroy marine habitats and throw each a systems out of balance. started 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 gives the salmon. it's typical consistency and look while many people will continue eating, fish and meat, others are switching out alternatives, which is great news for our ocean climate and the environment. so how about having a big in 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. 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

choosing the joy of the ride over the annoyance of the traffic gunners. revolution. i want you to verify thing is this about you but but now that unions will check it out. they 77 percent next on d. w in the glory days of motor racing, one means stands apart from all the rest, show up until 1989. this race tracks near 10, i wasn't for the fastest drivers from all over the world. we're meeting legends from indian motor sports and learning about the legendary solar team. 60 minutes on d. w. 12 in progress pop calls to everyone who wants to know

more about the topic that concern us about this story is beyond the headline world in progress. the w cost cost the welcome to the 77 percent program. on this show, we buckled the important things for africa. i am michael, and i'm excited to bring you this edition from across the street show is inspired by you actually. you've been talking to us on social media about the challenges of traffic toms. so we decided to take a closer look. so yes was coming up on the program. land wide traffic jams, robin young people of the fleet.
