marriage has been legalized and more and more discrimination. we also because like instead of 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, 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 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 organs. there are also many 3 d printed houses, just like these environmentally friendly once the us space to start f as your 3 d printer, 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, outer structure. i sure says it's method of constructing houses, it's 70 percent faster, and 30 percent cheaper. so conventional building method 3 d printing is to put 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 it's reused or recycled. 3 d printing could change this as materials are considered more resource friendly. cd 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 of you have pin failures or other things, but it really reduces it because instead of getting rid of the material, you're just building up what you're in addition, less storage space as needed because the building materials are to 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 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. does that kind of, uh, 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 any wings. 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 testing out ways to make them into a new product. 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 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 end 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 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 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. probably the ones 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 uses much less energy you'll via 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 because i'm like the 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 out the local soil, mix it with plan hey and then the parental can begin not to mention that book as 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 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 that worked together and, and liberate. 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 eyes, 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 touched 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 the completely autonomous construction turns print while scanning drones check that everything is going to plan. the idea comes from nature. it's mobile on how what's behind these natural builders 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. the benefits from the the fee laws are 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 limbs. 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 went to 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'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 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 a lot of the meat that people to consume today. but 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, meet 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 threatens to destroy marine habitats and throw each a 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 vague 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 for the 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
