3D Printing and the Northern Walking Stick Insect SciShow Talk Show 18

hello and welcome to another edition of the scishow talk show today we're talking about 3d printing and we have lots of examples of 3d printing because of our guest hello whose name I forgot Ben Malou Ben Maloof sorry that's okay this is amazing stuff that you have brought to us so tell me about what you do I essentially 3d print for a living so I work for a company called acuity design and we prototype we design and prototype products for people in companies I think I guess I brought one thing that is actually a prototype for somebody this was like a skateboard wheel core so they're just there that was gonna buy you some urethane right yeah so so they designed it they sent the file to us we printed it sent it off to them and then they can test it and then they would have it mass-produced in some other way right yeah they would have an injection molded yeah or whatever but so yeah 3d printing just enables you know relatively cheap production of plastic doodads obviously there's you know the the higher-end 3d printers can do metal and things right but we don't we don't have that capability yet so how did you get into this what what do you know that makes you good at this I was just getting my graduate degree in media arts and integrated digital media and the school bought a MakerBot thing ematic which was sort of the first consumer level mass-marketed 3d printer I basically ended up being the one that did most of the assembly on it so I was the first person to run a print on it and then I just you know just sort of blew my mind and right and I was already doing 3d modeling and 3d animation before that so it was all of a sudden this way where I could say okay well if I you know if I model this squirrel which I didn't but if I had modeled this squirrel in the computer you know it's stuck stuck in that two-dimensional plane you know you can rotate it around but you can't touch it and all of a sudden you can make it a real make it's a thing so that's pretty great yeah so after four so that's sort of my thesis changed to 3d printing and then next thing I knew I was prototyping things for people and needed to buy a bigger printer so I bought the parts and built a printer then I joined up with the team and mechanical engineers and started a company nice so as some of this is your work and some of it is not mm-hmm yeah like these basically all these vessel forms or things that I've designed so and then I guess these these are sort of half my work after the word goes famous or Nicole Angelo yeah yeah but yeah I can see I give him a kitty right yeah yeah well he's gonna be much happier yeah yeah well he is obviously smiling bunny hat so that's I mean that's one of the amazing things about 3d printing too is you can take these objects you can sort of take possession of objects that right you formerly had no dominion over right because along with 3d printing we also have 3d scanning and so with these it was scanning cheap dollar store stuff and smashing him on to priceless works of art this has been my favorite thing so far I just picked it up and I was like does it come apart what does this do and then if you twist it gears around into another cube I mean that's amazing I feel like there's maybe some rubik's cube technology that's going to be added to this and then you would yeah you would think that that would be the next logical step there's currently just sort of one website that hosts a lot of these files and that's Thingiverse so it's the universe of things and so that object was designed by a person who goes by the name of Emmet and he designed this using native gears and shared it on Thingiverse how much does this cost to print in the materials materials probably a dollar - Wow yeah the the material for the for most of the consumer 3d printers is about it's about 40 bucks a kilogram so maybe three bucks but not much I'd totally buy this for more than three bucks yeah yeah exactly but you probably wouldn't buy it for how much I'd need to charge for it that's Susy and because of the cost of the machine and your labor putting it together time and yeah so you know I I've seen those sold online for as little as twenty but those people are probably not not making a lot of money yeah and yeah and then of course that's this one is actually powered so it just it just even and this is another thing averse design where somebody said well if you just print this part and put it on a geared motor you can have it sort of run on its own that's awesome yeah now I get to show you an animal an animal yeah that's exciting yeah and now we have some somewhat frightening animals crawling across your 3d printed items how did that it must be Jessie's turn these are Holmes and Watson oh good can you tell the defense I don't think so I think they're just fine these are northern walking stick insects okay you can see that they're insects can you count their legs they have one two three four five six yep these are not antennae those are antennae look at what he's doing right now you're making them look like antennae I have to be a stick sticks they have amazing camouflage to blend in now if they were on okay we have a ficus tree that these guys live on and it sometimes takes me you know I wasn't there I I don't give up easy so you know I don't I don't spend five minutes and walk away I have been there for 20 minutes trying to find these guys they are amazing a camouflage they're very patient yes he's no moving but they have amazing look at me can hang upside down oh yeah but his abdomen you know is a heavy what's the thing these guys eat what they live on so they eat leaves that's all they eat they don't have a mouth parts really anything besides that up there too but they do most their feeling with these front two feet here they have a hooks on their feet and also suction pads sticky pads so they can climb up any surface and hang upside down like this now they actually have to hang upside down to be able to mold so insects they molt they have that exoskeleton and they have to grow bigger they think molds about five times in their life cycle but in order to grow bigger they have to molt and they're so weak they don't have much muscle in those legs but if they don't have something to hang upside down on and use gravity to help they'll get stuck and they won't make it through that mold mmm so I actually don't have much power in those little flimsy little legs would you like to feel what why does it have so much body where are you going well yeah now you're moving it's just got a lot of body it's it's a big anime this is all abdomen and then the thorax is right there where all the legs attach to its head up there so the females are gonna be larger than the males and they need that extra space in their body to hold the eggs and these are these are females okay are they fully grown they are fully grown and I these are very large northern walking stick insects I mean I think they're in their last molt they molt it twice with what well we've had them so and what's really neat is these guys so they they're mimicking plants so they'll get eaten by birds and things like that actually bats prey on these guys too they tend to be nocturnal trying to avoid predators and bats use echolocation they don't use eyesight to see them actually are pretty good predators for these guys but uh so they're making plants to protect themselves and help them live what's really cool what these guys do is their eggs have a little piece of like sugary type substance attached to him and it mimics a seed that a plant would drop so ants come along and they take that little what they think is a seed but it's actually an egg and they take it back into their little ant hill and they eat that part that's good for them and they throw the egg into their waste pile and then these guys out in the little ant waste pile is got some good stuff in it they're really making plants your face is terrifying yeah I need to get and you're trying to get me a sci-fi show crazy again it was any bigger it'd be believing there are actually so stick insects there's quite a few species is about two thousand seven hundred of these species we do the Adventist I can feel them feel I'm talking on my skin but the largest stick insect is eighteen inches oh that's a big bug so these guys aren't aren't that big this is about as big as they're going to get these are huge insects they're pretty big so you cannot say that they are not that big I can't believe they live in America and like you just never see them huh you don't see him because they blend in the colors even go on yeah yeah yeah I mean it looks exactly like I'm looking at it if like the closer I get okay now it looks like a bug but anywhere else it just looks like a bunch of sticks what are you doing he's like trench stick bug what what's out there what's out there you don't have very good eyesight huh there's no no leaves here at all these guys can even if they're gonna really try hard to pretend they're a stick some will wave a little bit you know pretending they're in the breeze I noticed that when I bumped mm-hmm yeah bumped Michelangelo there yeah they'll even go so far as losing sacrificing the leg to still pretend that they're a stick Wow they'll just stay there I feel like there goes my leg running they can regenerate it again good eggs back and we we recently talked about poop and you can the background their eggs and also poop and actually just kind of opens up in this little round ball comes out well round poop ball yeah yeah where did where do you find these in America so where do you minute northern where did you find these we find these these guys actually came from a friend that lives in Pennsylvania and these guys there are they are illegal to own for a normal person they are a terrible invasive species the Indian walking stick is probably the worst invasive species they have they people think they're really cool teachers have them in their classrooms they like they can lay hundreds of eggs and then they would throw out the substrate and the little eggs would hatch and decimate plant population areas so now they've put a ban on these guys yeah I see it's just sort of as they walk they shift back them yeah they kind of go like they're I'm just a stick you're just a stick these are fascinating I can't believe it's on me honey can I like try lived him off and you can feel that he's like what no no I didn't like that unit use Mosby's pretending to be a stick man don't run away oh now he's on my shirt this shirt super sticky you're like it you're like a parrot he's like I gotta get to the highest spots gotta get on the shoulders into your shirt there he blends into everything he's to stick except Michelangelo no II did not I still think he should grow let's go go go thank you throw your hands in the air babe thanks for showing off your stick bugs with us thank you're welcome I love you except your fists anymore thank you for joining us this has been really fun episode of scishow talk show thank you yeah you're welcoming me it's been great yeah what else do you get a have a stick insect on your hands and thank you for watching if you want to keep getting smarter with us here at scishow you can go to youtube.com/scishow and subscribe wave goodbye
