 Hello, that's me. That's who I am. That's what I'm talking about I genuinely did my PhD in 3d printing shape-changing jelly and if you pay tax in the UK you've paid for some of that And I am very grateful. Thank you Yeah socialism So I prefer to be known as scary my pronouns are they then I have a legal name And that is what is required if you want to give me money or look at my academic publications Which is why it's up there. I've realized that if I'm stride around then I cannot hit the next button Which is a bit of a failure mode. I have to say and so the thing people always ask is Why So Much like the the the last speaker. I'm going to assume a few things as actually as axiomatic 3d printing is by default good We can debate this and I certainly did not agree with that by the end of my PhD But that's what I believed at the start One thing you can say for it is that it lets you make lots of different shapes with one piece of equipment Can't argue about that bit the rest of it Shape-changing things. They're pretty awesome So I don't know how much you know about pinecones I repeat my previous talks at EMF about shape-changing materials and how they are awesome But pinecones can they know when it's wet They close to protect their seeds. They know when it's dry. They open to disperse them. They keep working They've dug pinecones out of million year old coal seams and they keep moving you can break half of the bits off and the rest that's left Just works. They don't require a power supply. They are not vulnerable to hackers from any geopolitical area. I Could do with some of I would like maybe one percent of our tech to be as reliable as a pinecone So I got the over being out done by a bloody tree and that's why I decided to spend four years of my life in a lab There is more on this at my previous talk So there are people doing shape-changing materials that you 3d print. They're awesome they have a lot more money than I do and I learned that the lab MIT where they do this their machines are half a million quid and They have two dedicated technicians to look after them and their work is beautiful and I admit It's more beautiful than mine, and it's it's it's more photogenic than mine, and it's more reproducible than mine But mine cost me 750 pounds So if you normalize it and ignore the cost of my labor as vaguely works And a final point which is an interesting meta point that probably people who know more about history and philosophy than me can say But historically we've done some kinds of engineering more than others We do a lot of work with bricks. We do a lot of work with metal We do a lot of work little bit of work with wood less now less on ten secrecy more on compression and We've done a lot less with soft materials Which is weird because like we are entirely soft materials and we interact with a lot of the things we use so there's this big gap of People know less about working with rubber people know less about working with gels That's why jelly so 3d printing cool shapes responsive things pine cones are defying me and soft materials jelly because a lot of the people who do this work with those very expensive machines and Those use proprietary plastics which a I resent having to pay for and B. I am too bad a chemist to be trusted to make So I'm about good enough to cook and that's why I do what I do so This is where I started open-source 3d printer and rust oak mini because Delta printers are cool again We take this as axiomatic I modified this to have a nozzle head and a syringe extruder This is actually v1 it got updated you see an action here because I had to submit it in PDF. So no videos The sort of materials I'm using are a jelly You will know if you've made jelly that it starts off as a liquid And then you have to set it into a sort of more solid structure I can bore you endlessly about the technical differences between those but as long as you know that it is runny and then it is not runny that is the important bit and The way that you make this special heat sensitive jelly Into not runny needs to be running to go through the needle and then not runny to put the next layer on top And you do the not runny by putting some LEDs on top so There's a really helpful company in Shenzhen who helped sort that out for me for very little Compared to what it would have cost me in this country. So I bolted that on cut up an old heat sink. It's an incredibly lossy system Put a syringe extruder on the top and whacked it in a fridge that used to hold drinks that I bought second hand on eBay and That's what you need to make this particular kind of shape-changing jelly I can again bore you about how this jelly changes shape but if you understand that jelly is mainly water and What's not water is like a network of long thin molecules like cheese strings, but with less nutritional value and even less and The cool thing about this is that when Environment around them gets hotter They shrink up and then they kick out all the water that's in them So think about a jelly where you've taken all the water out That's going to be a lot smaller and that's how this tech works but If it all got smaller at the same rate that would be the world's most boring shape-changing item, right because it just Into a slightly smaller thing what you want is two layers one that gets a lot smaller and one that gets not much smaller and then you can start folding and Making sheets and stuff like that so you use the UV to make it not runny and You squeeze the running stuff through and then the UV you set it into shape And you get this jelly that changes shape when it goes into something hot So these it's a rule that whenever you're doing science you start with the simplest Situations so one-dimensional beam 3d print a thin jelly and 3d print a thick jelly That's one thing I changed and on the left is what they look like when they're cold on the right It's what they look like when they're hot. So these are the same samples and you will know that they look different They're here. They are white here because they've checked out all the water So what's left is I take rather than transparent and the interesting thing is that it's it's kind of curving up in a funky way Which is kind of cool and the weird thing is that some of them bend one way and some of them bend the other and I don't know why And neither does science And I can't figure out how to publish it because none of this is replicable so I Swear to you it happens. I swear to you. I did it. I swear to you. I did not fabricate it Nobody can explain it But it's a really interesting technology because all you need to make them fold different ways is to shine light on them from different Directions and make them different thicknesses, which is again really controllable So you've got your 3d printer which can make stuff in any shape Then you've got two extra degrees of freedom No one way like where you've shone the light on them which way they bend when they get when they go into hot water So there is another requirement when you're working in soft robotics. You have to make a gripper. Oh, yeah Technically this constitutes soft robotics because the bar for robots is very low If it does something in response to an environment, it's a robot. So I'll claim it. So Jelly robot sort of So 3d printed flower. So start off in cold water. That's top left put it in hot water and it goes I Don't really know what this is for to be honest It could be like something that we could be like an egg cup the auto deploys Could be something that we put on the seabed that you know as the ocean gradually warms can give any sea life Just a little reassuring hug could be something that we use for meditation, you know Meditation is very in right now for the future generations when we've wiped out all the trees We can show them. This is what pine cones used to move like Anyway answers on the postcard for what the point of this is but there you go 3d printed jelly that when you put it in hot water closes up If you would like more on this and I have no idea where I'm on the timing Lovely, oh, I'm on time and all this and on time Here is a three-minute video of me at the Royal Institution talking about it I put up a video of the machine working so you can see the Absolute strings and wishing that hold together a Responsive jelly printer built on 750 quid by me in a broom cupboard with a sign on the door saying all hope abounds in ye who print are here My thesis if you want all the gory details, I'm on Twitter for questions I do stand-up comedy about science as well as being a scientist if you're interested in what you do after doing a PhD in 3d printing jelly that changes shape when it gets hot the answer is I I consult on recyclable packaging and Also on food science vegan food is my favorite thing So yeah, like weird polymer structures edible and non-edible is my two branches Yeah, so you can like see me do other things And I'm trying to write this into a paper and I'm trying to document it really nicely because I would love to contribute This to the open source network because my major bug bear with these million pound beautiful systems they have at MIT is Nobody else can do what they do because nobody else has the money and they don't share the designs so All of this is built on things that are publicly available. I haven't documented it very well because they stopped paying me to do that I Will be working on that and if you're interested I can let you know when that comes out. Thank you so much I'll be around for questions. I brought a fan club. It was not intended So my name is Serena And I hand it in this proposal about 36 hours ago So that's not slides because I didn't do slides because that I didn't bring my laptop. That's actually Yeah, let's show from the beginning that's the publicly available Distillation of my of my master's thesis The idea of my master's thesis was to develop a set of recommendations on how to make research in HCI mostly more inclusionary It started out with a focus on gender, but that's because it was funded partially by a horizon 2020 Project and that only focus on gender and I open it up more widely because there's a lot more things that cause discrimination and exclusion than only gender The recommendations are Available on our website you can Look at them and there's also this PDF that you can print out and I basically looked at what HCI Publications from well-known when use did good or could have done better in Documenting their research in conducting their research in the methods that they used And Drew recommendations from that it's 15 by now and It's actually some of them are No, brainers, but you need to take the time to think about the stuff that you're doing and how you're doing it And why you're doing it the way that you're doing it and very often people don't have the time to do that or in Science technology engineering and maths where I come from You don't get the education to do that at least in Austria where I come from So it helps to have Some recommendations and some information on what you should be thinking about in order to know what you should be thinking about, right? That's two of the cards They all look the same. They have these icons on top. They have a short title They have a couple of questions that you can think about yourself or discuss with your team members there's Explanations and examples that you can follow that you can again discuss with other people and I put a footnote That's because Again, the assumption was that the target group is tech people who do not know shit about sociology drawing from my own experience And So that if you sit together with your other techie people and no one knows shit about stuff But you're usually bullying each other because you're tech people and we're a toxic community You don't have to ask someone who's holding the description of the whole of the whole card deck if you don't understand a word Instead it's there on the card that you're holding in your hand and you can look up the the definition of the word yourself and I try to keep it in understandable terms sometimes hard because English is not my first language and Sociology is complex What else is there the the color of the title bars actually indicates a Somehow Position in the project lifecycle so we start with stuff like acquiring Funding Conducting research I put that up earlier. I forgot it I've been talking about this for three and a half years and I still stumble over across some things and the icons on top are like thematic groupings so that you can see that some things might be happening in different phases of the Project, but they are still somehow connected to each other Yeah, how am I with the time lots of time still lots of time I'm gonna have my defense in three weeks and one of the questions that is probably coming up and some of you might be asking yourselves is why is this even important and it's important because one we have a lot of Exclusionary stuff happening. We have a lot of tech that is not developed to work for many people but just for a few who are usually white cis-head males able-bodied and so on And it's really hard to think outside of your own area So if you're a tech person, you're gonna be in a very homogeneous Surrounding and it's hard to think about the issues other people might have So that's why they are here second is there's actually a scientific issue because if you look at research, there's often not all of information for example on Assumptions they made I looked at quite some research that was tagged as gender research and Nearly none of them talk about how they operationalize gender. So what do they mean when I talk about gender? Do they mean biology? Do they mean like do they literally mean? Distribution of fat on your body because that's not gender, but they call it gender and That's one of the things that needs to be done In order to make research That's a reproducible issue that we have before And the and the third thing is that I hate injustice and I just figured I could make a difference with that work and I hope that it gets spread of it and that's also a reason why I showed up here and There's the link to The website where you can find it. It's really not pretty because I'm not a web developer And you can look at the cards you can download the whole PDF you can there's a Drawing stack is what I called it. So you can draw a random card. You can refresh and draw another random card you can go back to The the info page and it's available in German and in English if you're so inclined to use German Right, that's that I'll be here for questions. Thanks
