 Okay, hello everyone, I'm Julio and today I will talk to you a bit about the use of Blender in general of 3d modeling in the world of health care and the work we did with wasp. I'm I'm talking about Wasp a bit during the presentation and now let's see a video just to start crazy Sorry, I know this is nothing to do with that care, but it was something I needed to explain you Who we are with wasp? this is the house you saw in the video and Basically, we are 3d printing company based here in Italy between Bologna Ravenna and We are working with 3d technologies since six years Our main goal is to get all the Best technologies in the world all the possibilities that we have around in the world now and Bring them at At the human needs so like creating this connection that can use technology in order to really help Basic needing you saw this is one of our main projects about the housing. So the idea is creating a system for Sustainable housing all around the world, but there are a lot of themes that in our world need Innovation and research and our goal is to bring these technologies in the fields So food energy and health care of course is one of these We like to say we're not that fool. Do you think we can save the world? But we're for not to try to work for it. So like Innovation is also a responsibility. No how do we do this with 3d printers and We are developing 3d printers in Sears. We have developed the various kind of machines for working with different materials in different fields of application and What I think is the best of this is that our work as a team Gathered so much collaboration that we had the possibility to work in so many different fields So starting from traditional 3d printing with prototypes and models Then we went to printing different materials like porcelain ceramics and creating complex geometries growing bigger in scale. This is a ceramic vase, but also developing bigger machines for creating furniture and Objects that could be really used in real life and then Increasing up to the scale. This is one of the projects we made in which we created like a scenography for a theater One of the applications of our printers since the beginning has been the one in the medical field so this example you see is a Is the printing of Active medical material that could be used that during some researches So Medical field why 3d printing is good in medical field for one main thing Producing a single piece or a unique piece with 3d printing is very convenient. You don't need molds, casts and 3d printing as a cost of production, which is the same for a single model or for various Shapes of production for the printer. It doesn't change anything. So this makes possible to realize Pieces and objects for each patient at a very low cost compared to traditional technologies Also, we can include all the possibilities of digital design, of course inside these workflow in 2018 we developed this which is Abundant of stuff we designed for making all the workflow inside in this case orthopedic laboratory suitable for the use so Starting from the scanner the one you see on the left and then with 3d printers certified materials A workstation for designing it was possible to complete all the process from scanning the body of the patient To the final device 3d printed with certified material and this was a main goal for us to bring the technology inside the the world of orthotics the world of orthotics as a Traditional technique which is really It's really about crafts it's really about Handmade processing and bringing digital manufacturing there is not that easy. So now we're going to see What this means? this is a Video for the promotion of the system Basically the important thing is Understanding how this can happen. So how do we switch from traditional technique to the new one? consider that the first thing in both methods is Gathering the shape of the body. So in the traditional technique We used to cast something on the body so usually the cast is made with a Material that needs to dry and when it's hard it It's used as a mold for all the work and after this process You have to throw it away because each patient has a different cast and this has to be thrown away and Cannot be stored on the other hand with digital technologies. We have the possibility of Using 3d scanning so minimizing the time of scanning and improving a lot the quality of the acquisition Also, we have the possibility to operate with different softwares and technology To modify this data in a way that just cannot be done with a physical cast Also, we are talk about it later by using this approach you have the possibility of Creating libraries and storing all the data of the patient. So not only the 3d scanning but also the The actual device so if a patient comes to you two years later needing the same kind of Device you can actually produce it with the data you stored and actually use the Years before so here you see we are We are working with the different kind of devices. We are working in 3d braces corsets but also insoles but also Aphos and any kind of thing that actually needs to be surrounding the body and Working like pulling and pushing in some way Here is very interesting how with 3d printing we can create shapes that are actually impossible or very very complicated to create with the traditional technique and this is a reason for which Importing all the knowledge of the digital manufacturing in the world of health care is very important and crucial So we are trying to develop this kind of new way of thinking The other interesting thing about this is that we can actually Work work together with traditional technique and new digital technologies So they can work together in order to get the best result as possible But the main question and the other thing is why we already said something But why introducing 3d technology and orthotics if I have to convince someone who's working in the field and maybe is already using all his workflows and Traditional application of the technology. Why should we switch to a digital? A digital way. I decided to do a SWOT analysis after all the experience and the cases of people we know Coming into our Reality and trying to figure it out how to use the these technologies I created like this analysis of strength versus weaknesses and opportunities versus threats So now let's see the main points no costs. So you have a great saving time and resources with a cast which is also quite a problem for the for the dismantling and After the use they need to be thrown away with costs and clearly environmental the environmental implications the create the possibility of creating long terms and accurate libraries with a patient so this is improving a lot the service you give to the patient and also the possibility of Saving data that couldn't be stored just physically You have endless possibility of design due to the wide range of Shapes you can create with additive manufacturing and of course the wide even wider possibilities with 3d design and As we say reduce of waste and labor on the single piece. So I do not I do not discard a part of what I'm creating for example as if I'm working with a shit And I'm cutting away parts with additive manufacturing. We only depose the material we need Last but not least working together with traditional techniques. So a lot of our customers actually put together Traditional technique with maybe some printed parts that use as a mold or use as accessories and this is for me is very interesting What's the weakness? What's the problem in this? Mainly this that's bringing the technology to an orthopedic laboratory is actually something very difficult to do And and appreciate for someone who is not used just use a computer every day and this is a main problem What are the opportunities of the technologies a smarter workflow? So we're saving time resources working more accurately innovative products with new technologies We have the possibility of creating a wider range of products maybe even exploring fields of the of the Rehabilitation of the cure that now hasn't been explored for technological limits and Also, not less important low budget devices for example exploring the uses of additive manufacturing in contexts and in countries where Healthcare must be really low budget in order to be suitable for all the people and this is the case for example of a project we developed in Damascus in Syria with laboratory we are we're developing with the Syrian guys and Exactly bringing the open source projects like enable I don't know if anyone of you knows it and creating them with printers. So the opportunities are a lot and again, what's the threat? Probably and that you will have to face a new way of seeing your work So what we're doing basically with what's mad is trying to remove this separation between three technologies and that care-word It does exist the separation a lot of proprietary softwares exist in order to give People these tools but actually the offer sometimes It's very expensive and not really at the use of the people because maybe it's complicated because maybe it's not It's not spreading that much. So we thought of doing something a bit different something easy to use so for someone who has not 3d modeling background or as knowledge about computers Something that could be open source to reach actually everyone and to spread it all all around Also in order to really have this technology to work in the field of healthcare and then integrated So that could be part of a software that gives you a real and professional Possibilities who could work work it out with this We need the help of someone knowing very well software and this one is Alexander Zamparelli who is here I don't know if in the morning you saw his presentation in the theater if you didn't check it out on YouTube because he was amazing and Why Alexander Zamparelli because in his experience He had me working especially in the project mocks in 3d shapes modeled on human scannings and that then needed to be 3d printed This was like I see it as an exorcise and exorcise and a research But it has a lot to do with healthcare because basically we're talking about human body we're talking about Managing these digital data and getting out with the final input With a final output that could be actually wearable on the body. So This made him the best person to do the add on with and we went straight on last year in 2018 with the developing of what's met add on for blender 2.8 and As I told we wanted it to be easy to use Which with the interface of blender was not that easy to achieve Open source so for this there was no choice and blender was the program for his powerful possibility and the great community around it and Integrated Giving the possibility to the users too if they wanted to actually use all the tools and all the powerful solutions inside blender Even if they were not actually inside the add-on, but we wanted to leave them free to use them so Let's have a quick overview inside the inside the add-on Everything starts with the importing of a scan Doesn't matter which scanner you are using sometimes in proprietary programs. You need to use a specific Descended scan with all permissions and everything here You can actually scan as you want and import your STL or any kind of file you have here Fixer based on remesh modifier that actually gives you the Makes you certain that everything is manifold and then you can switch to sculpting tools In order to fix some scan problems, but also starting as you see now making some corrections and modifications that can go into the Into the medical medical side of the thing so you can push you can pull you can actually smooth This is another tool we were asked from the professionals Which is based on lattice modifier and it gives you the possibility to work with a grid and Modifying everything for points Or even directly with a pre-made set Twisting some sections as you're seeing now. So for example now I gave 15 degrees of twisting on a side after these modifications You should be done with the with the corrections and you can go and And cut what you are not needing. So usually we don't need arms. We don't need the head So no problems. We're just going to remove it After this we are done and we have basically we call it the positive of the of the bust and We are now switching to the most important part of the add-on and Why did we decide to? Create the the model like this because for someone approaching for the first time 3d. It's not that easy to model It's not easy to think of vertex vertices and to move them to extrude for them It's absolutely not easy. So we thought of weight painting as a really intuitive way of Creating the shape so just painting in red what you want as the actual brace the final brace You have the possibility to to shape it and it's really really easy even for someone using it for the first time Also, you can use it actually with with a tablet so with a pen you can make it even easier and And just sketch it as if you were doing it on the paper So after this What the software is doing is divide them divide in the blue and the red part into different Into different components the red one as a certain thickness Which is the actual thickness of the final device and the blue one is something that can work as a support in 3d printing Or can actually be removed So you see now we are setting the minimum thickness for the gray part and the actual thickness of the Orthesis in the max also we have a specific control on the falloff of the border So I can choose to have it linear I can choose to smooth it I can choose to create it custom as I want it and This is very important because this gray part has to be removed after the printing So it's very useful to be printed working as a support and something that keeps everything together But later when I have to remove it if the falloff is created properly It's very easy to cut it for example with a small blade and without needing of Complex tools or something that maybe danger is also for who's working on that Also, you see we have two utilities one for smoothing the support and one for cropping the top and the bottom If we don't need it. So we have everything super optimized for 3d printing with this Kind of easy workflow Here we have a phase in which the object has been baked You see and I can work here with other blender tools if I want to create some more complexity So I want to create accessories holes something Created more complexly I can work there or else I can go to the exporting and I have the model exported Ready for the 3d printing. So you see this is the slicing software where we prepare the model for the 3d printing effort. Give it Give it shape So so you see this is the preview of the of the work that will be done from by the printer You see printer is increasing in eight and this is just a preview But what comes out of the printer is actually this and all the other workflow is very controlled We also tried and this was very important and difficult to avoid and remove all the stuff that could create the problems that could create maybe Misunderstanding so it was very important to set the values of the units It was very important everything if it's not enough and you're looking for more complexity as I told you There is the possibility to work with the other tools in blender and for this the education is crucial So what we decided to do is creating and organizing a specific course for the use of blender in orthotics and this took place in September in Bologna and it was very interesting. It was a four-day course For people that didn't know anything of blender and we started from the basics the first two days And then we had the possibility to go deep inside the topics and at the end of the workshop They were able to actually model on their own from the scanning and everything Something like this like an AFO or something like a protective mask This is for sport use even if it seems kind of superhero It's actually for sport use or for example, this is a socket that can be put on amputations and This for us as a great meaning because giving the possibility to the ones really working on the field to have access to the technologies for us is crucial and We found out that the main the main problem in all the workflow was actually this one of 3d modeling. So we found out That we have had the possibility with blender to create a very professional and the very suitable tool for this and We are very happy now to have the possibility to spread it You can download it on github and it's free for the user for everyone Because our purpose it's really to share this culture of open source knowledge also in in the field of health care So I imagine in my in my vision. I imagine That maybe one day in another country Maybe in some country where you have problems or you don't have all these resources You have the possibility with a small 3d printer and your computer To download this plug-in and start creating useful stuff for people so this is our concept and we will work will work and keep on working for make it real and Thank you everyone. Then if you have any questions, I'm available for any kind of specification even now if you add some curiosity, I don't know Yeah The ones you saw here is not it is not it's but we are also using a very good one which is open source and it's called the slicer and written with the three in in DE and this is a very good one and It's a it's also improving a lot in the years and now it features basically any kind of Any kind of feature you need for printing your model. So yeah, there is the possibility of a complete workflow with the free softwares Other questions Creosities, okay
