 Hello Hello Blender conference her Blender hats. Hello Blender people We are two professional footwear designers Uri Shushka plus 20 years of footwear experience. Youssef Taran five years of footwear experience bought footwear designers, and we are here to present Something a little bit different. We are here to present an open source footwear project that we have created ourselves It ends up with this shoe that we will now share in the audience. Please have a look Eventually you will all be persuaded and you will be able to create it your on your own you just downloaded the download the files from the website and Produce it in your living room. It's an open source project. It's a passion project It's something that we do after work We play around and this is what we will present And I'm very like Blender is our number one tool. We use it really frequently and for several years already and Not only Blender gives us a tool to make the design in a new way Blender also gives us opportunity to think about the open source and open license So as all of us and all of you know here in audience the power of open source in a Blender We try to get inspired by this Ideology or this freedom and try to apply where this thing This freedom is applicable on something like a fashion in our case a footwear So we would like to show you our workflow how it goes from the idea to the physical product when it's run on Mainly on Blender engine. Let's get to it Starts with research. Here is a small sample of shoes that are tested almost on daily basis. We are both vivid runners We like to run. We like to test shoes. We like to base the design at something at the proper research one of the very easy research way or very very easy way to research stuff is to Document it here. You can see on the left side Running in the open source shoe in the middle. There is the barefoot running and on the right side is overlapped over over each other so the research is kind of the The base of anything that we do. This is the classical Physical research. However on slide three we right away jump into Blender It's really from in this project as you have mentioned we want from zero to the physical product and Research really or building a shoe really starts from the feet because shoe is the thing around the feet So as you can see on the image, that's a picture of my shoe of my feet I used a professional 3d scanner for for the feet and This data from the scanner was just imported to the Blender and that's where the journey started and it continues Blender creates this kind of a digital playground kind of a workshop in which you can Play with the product without making your hands dirty, basically. So That is to illustrate here as well You can test lots of things in this digital sphere. You can play around with it Before you start manufacturing it and it's great to see the community behind the Blender Because actually many things that we applied on in our workflow in our process actually came and get inspired by The people that we see here like something what do you use for a movie for a CG for what other aspects? We just see okay that applies for us. We can it can help us. So It's it's really powerful The first thing to design on the shoe is always a last so the shape of the foot and Blender helps with this a lot because Yeah, there is a lot of analytics behind a lot of measurements because shoe needs to fit Nicely on your feet. So we are using geometry nodes to do all the measurements We can interactively measure any diameter of the last we can grade the last to the To the old sizes that we have Think we can jump to the next slide Currently the We graded the shoe In nine sizes, but of course it's it can be graded and scale in any size. So again, it's It's great to play and Blender and a enables it this next step is always designing the midsole. So the bottom of the foot here are visualizations of How to start with it? Where does the where do where are the pressure points on the foot where are Where are the bones touching the ground like how do I? See it in the 3d. This is all enabled within Blender and you right here has a point about the dynamic stuff as well Yeah, because as as we mentioned, we are footwear professionals We work or we have experience with other like dedicated footwear softwares But really the Blender gives us opportunity to Visualize things that I don't see how I can achieve in other than How to call it gaming software that will allow you to whatever you imagine. So we do static visualization we do Dynamic visualization we can mimic the shoe or feet in the movement we can see visually say where the bones are we can see and Think about where will be the some point of hard surfaces or like We can visualize too many things and at early stages where the flex points are very important So this is for the midsole design and it can be as simple as Being able to grab all the elements together. So there are many traditional footwear 3d softwares We will not name them today But there is no possible to grab the midsole and the upper together and just tweak it. Of course, this is a Overkill kind of you will not design the shoe like this But it's a simple tool like this already improves the footwear design workflow tremendously for Blender designers This is nothing special. This is everyone knows that we can do it But really I'm not aware of any other software when at the same time I can build and redesign error shape the shoe last the bottom the outsole and the upper because for example if I want to Make a Specifically fitting shoe for any other feet. I can change the width. I can change the the drop and All the diameters if I do changes on my shoe last Automatically is connected to the outsole and that's amazing and powerful thing We are talking about the footwear 3d softwares Of course, we are aware of different polygonal softwares But Blender enables it and we can design the shoes inside when we are satisfied with the Shapes with the last with the bottom we go into rapid prototyping and I'm sure you are all aware of 3d printing Here especially on their side on the right side You can see the last number 42 so the same size but with different widths And yeah, you can visualize as much as you can in Blender But then to actually hold it in hand and be able to compare those small differences player Big difference in the final product of the shoe as as our goal It's not to end on the visuals our goal is not to make a renders and put it out on our portfolios We are really creating a functional footwear. So yeah Ability to 3d print overnight Design Validated it next morning. It's really speed up the process dramatically And it can be a simple small 3d printer here again a very easy trick Sometimes we are challenging the day. Okay, you work for a big companies You have access to whatever machinery you have but in this specific project. It's like we We finance the research and development by ourself. It's really our hobby. We don't have the budget for a high-end Machines so for example here we yet. We are using the Prusa machine or any low-end mid-end 3d printers, but if your 3d printing plate is too small for your object just cut it in two make it in the two pieces glue it afterwards and Trada you can validate your design you print it overnight next morning You come to the office you see the thing and you can go back to the Blender and do more interactions iterations works magic and It's always for designing for us. It's a lot about the speed and efficiency So especially in the concepting phase we try to keep one master file that rules all the others So in the concepting we are preparing the maps That we apply on the object so all the upper part of the shoe it's often just as one single object that it's mapped and That allows us to make a quick modification and iterations and Those maps are used for rendering for the visual check or check on the screen and plus those models are great also for a 3d print and Also, and also the same master file is a source of data source that we actually export the the curse to Dedicated to the pattern making software for for footwear developers We export files there and those files goes directly to the cutting machine So that's the connection from Blender to to physical work that also works perfectly and we don't have any issue with that It's a very quick iterative way how to produce lots of designs visualize them theoretically 3d print them This is the already the last step when you are starting to laser cut it As I think you can see on the next slide as well where when I have the patterns I bring them to a laser cutter Cut it out stitch it together in two hours. I have a upper that I can Start using or stitch it to my previous shoe or I use a CNC router get the files for the bottom CNC routed out of the foam easily available and Glue it together and here I have a shoe. Yeah, and with the shoe I can start running This is pretty exciting and obviously we know that not everyone has at home the the machines like CNC Like 3d printer laser cut for that. We are closely tied up with the fablabs. That's the global Digital fabrication labs that are everywhere. You can find one in Amsterdam. You can find it in other places You just go there you take your training and they allow you to use their machines So today on the board there are like 2500 drops so actually our open source design can be produced and manufacturer almost anywhere on the planet But the design is kind of finished and we are we're very happy We are always very happy to validate it to start writing with it. You can see on the right side I ran a marathon in the middle you right runner cause it's a marathon just Couple of weeks ago. There are some trail races It's a proper running shoe and there was also the goal in the beginning We want to make a shoe that you can run in It's not just something that you step into and take a picture of this is a serious shoe that you can all make Yourself enabled by Blender one of the marketing statement that we are using is that this is the worst fastest open source running shoes You can guess how many competitor competition is this field, but maybe that's the way and recommendation for anyone if you want to be unique just do something completely different and Maybe I will just say the side story at the beginning when the project started I had like the goal for this year What about if we can make a marathon under three hours in this open source shoes So we team up with Yosef and Actually, he almost ruined the project because he ran this sub three marathon before we launch the project So like okay, and what are the challenges now for this year? Why when we receive the achieve the goals? Before we launch the project, but the point of the slide is you can really run in the shoe I'm wearing it right now. It has 250 kilometers on it one of the first Samples has like six hundred seven hundred kilometers on on it. It's a serious running shoe We enjoy validating and it's it's a lot about the sustainability like people are asking Hey guys, why I need to make shoes by my own otherwise. I can go to the internet click and have shoes tomorrow You have control over the design if you manufacture shoes by yourself You know how you made it if something goes wrong so you can fix it you can change it so Yeah, there is a freedom that the other shoes hardly can can offer You should go right now and download them However, Blender does not stop there as you saw in the beginning you can easily create a powerful visuals and We call this part of the presentation this kind of a digital photo studio in which you can create the digital twin of The of the shoe and there is four simple tricks to make a better footwear visual in Blender First one use a 3d scan retopologize it keep it in low poly the 3d scan doesn't have to be perfect. Just Make it as low poly as possible in tip number two keep the low poly and drive it through modifiers Those four are the best ones subdivision solidify especially when you split the three materials So the back face the rim and the front face. It's easily Editable in the in the modifier a tap and the bullion bullion for perforation for eyelets it works again rather quick iteration strong visuals the Third maybe the most difficult one. How do I do stitching if I really want to go for a realistic visual? We recommend to create a Stitching or to model the stitching so we model the stitch and then in video to you drive it through a Array modifier and through a curve modifier on the surface that you want to apply the stitch to looks strong Fort around a round laces in the curve if the laces Round just use a curve if it's slightly off You can use the profile curve to to change it if it's a flat a flat lace model it I would say much easier and Finally, you have a digital twin You have a digital twin and of course you're not happy with it because it's a render that you have created and It doesn't look as good as you want it. So you think um, maybe I Would like to make it more realistic the easiest way or rather quick way for a for a strong visual Take a picture of a background of a real situation and use this picture as a photo background on the right side you can see that The plane is slightly modeled to give a bit of shadows and then there is a glue bottle Downloaded from Sketchfab. I think Free asset to give it more realism and tada here is a Rather strong visual that you can use on the website on the poster Product visualization you are all familiar with it. It's more than possible in blender for footwear It's widely used not so much talked about in footwear industry product with or footwear product with is a visualization in blender We don't stop there. Of course when you have this digital twin you can then start changing materials changing colors So this is one of the simplest you change colors. You make it rotate You show it to yourself You show it to other people who would like to have it in in different colors You don't have to source the materials in different colors, especially you just do it digitally Yeah, you can nicely save the time if you know that you have these and that material in such a color Even from this pre prototyping phase you can see what you have on the on the desk What kind of physical materials you can imitate it and you can see how the shoe it looks like and then okay Maybe the the midsole doesn't fit in color and you can source that so it also helped for the In the color management for the manufacturing part that you can know what you will get at the end So very powerful and last but not least you can explain the product simple exploded view It's now used to explain the product to you one more time So that you go to the website open source.com download the shoe and start making your own footwear Here it's a simple visualization made in blender through the digital twin of footwear strong if you would like to know more about how to Make it or maybe question to the audience. Is there anyone interested to make the open source shoes? Oh Hell yeah, that was so far that the highest For the people who see it from the video it was almost 50% as I counted it Okay, so that's that's our website on the website You can find and download all production files needed for a 3d printer for CNC for for the pattern making As we mentioned everything is a license under creative common license So you can do you can make you can produce if you stuck somewhere in the midway try to contact us we are really more than willing to help you if there is some obstacle and Yeah, if you are able to finish the shoes absolutely Send us picture. We would like to see more makers more people are trying to work on sustainability and Do the things in their own way? Yes, please share. There is also the files The digital files. So all the blender scenes that you have seen in this presentation. They are also on the website It's not just the production files. It's also the Digital visualization files. So please download them. Look have a look at the stitches Have a look at the use of the modifiers and let us know send us pictures of your new running shoes So if you are a footwear designer, maybe that could be a good source of information or the exercise Please jump in take the file use the file share your finding impressions. We are looking to hear from you. Thank you If you have any questions reach out
