 Hi, I'm here at the ID TechEx show with Katarina who's a co-founder of Volterra. Katarina, what do you Volterra do? So at Volterra we make building hardware a lot less hard. So essentially what we've done is we've created what is the Volterra V1 PCB prototyping machine. What this machine essentially allows you to do is create your design in whatever software you're comfortable with and then just press print. Now what it's going to do it's going to dispense what is a silver nanoparticle conductive ink onto your substrate of choice to create the track pads and the traces of the board. After that it's going to thermally cure that conductive ink so that at the end of the day you essentially have a fully functional electronic board. Now what's really really cool about this additive technology as opposed to traditional subtractive techniques is that it actually allows you to sort of enter this new portal of advanced electronic manufacturing which can be done on alternative materials. So things like polyimides, things like textiles and plastics for e-wares, things like capton for radio frequency based applications, polymer thick films for medical device based applications. The possibilities are truly endless with this additive manufacturing technology for printing circuitry. Wow and how easy is it to get up and running? So who sells the materials and where do you get the substrates from? So the substrates you essentially can get either from us or from any supplier of substrates because substrates are essentially an endless supply depending on what type of material and what type of application you're looking to get. We do provide conductive inks. You're also able to get conductive inks from any advanced manufacturer out there so you're able to dispense not only our silver conductive inks but graphene inks, nanoparticle inks, copper inks. It's truly really dependent on the application that you're looking to do. And what sort of industries are buying these printers? Oh we have people from absolutely everywhere. We have people that are coming from the academic community using it as a teaching tool but also as an R&D tool. Also small, medium to large companies and basically everything in between. If you're an electronic designer and you're looking to build hardware it's basically a tool for you. And do you release pricing on this or is it dependent on the volume? The price of the machine itself is $3,500. With this drillhead attachment that makes dual-sided boards a lot easier that bumps it up to $4,200. Still the average user is going to get a return investment in about two months if you're prototyping quite a bit. Fantastic. And in terms of software, do you provide special software or can you use existing circuit design software? As the designer, you can design your PCB in whatever software you're already comfortable with whether it's Altium, KeyCAD, EGLE, just process it as Gerber input and then the machine will essentially do the rest. Catriona, thank you very much. Thank you, take care. Cool.
