 Hi Elena, how are you doing? Welcome to our conference, we are very pleased to have you. Thank you. So Elena is doing some very exciting work on using Graphene in a 3D printing product. Elena, so what's new? So as you might know that our company Graphene Laboratories and our website Graphene Supermarket was making Graphene for sale in small quantities for almost six years. And we've been looking for ultimate opportunity to use Graphene for commercial applications and about a year and a half ago we met with one of the professors in Stony Brook University nearby in New York and he's an expert in 3D printing and after we talked to him he convinced us that Graphene might have a lot of applications in 3D printing and after that we started working on materials, like materials for FDM 3D printing so in this case we started with polymer materials and we also started with Graphene nanopowder and after that we used our proprietary technology and mixed Graphene nanopowder with polymers and we can make Graphene-infused filaments for 3D printing and we successfully made first laboratory scale samples and very soon we're going to start selling it at a commercial level. So what is the added value of adding Graphene to the polymers? Is it conductivity? Is it mechanical strength? What is it? Yeah, apparently absolutely right. First of all it's conductivity. So without Graphene polymers do not conduct and there are a few additives which can be added to polymers and they can make materials slightly conductive and by using Graphene we can make it highly conductive and apparently Graphene also improves mechanical properties and also greatly enhances thermal conductivity which is also very important for many practical applications. So bringing conductivity to 3D printing is a challenge and what are the other solutions on the market and how do you think Graphene is better than the other one? At least we tested several different materials which are available right now and usually it's carbon based materials so it's like carbon black or carbon fibers and in this case we can get values by at least two orders of magnitude better if compared to the best products on the market yet. And apparently the long term goal for this project is to combine Graphene and other materials in one print and if you can combine many different materials in one print you can make 3D printable electronics. Excellent, so thank you very much Elena and I hope you enjoy the IDT Case Conference. Thank you.
