 I'm at the Cocoa Press booth with Evan. How you doing Evan? I'm pretty good. Awesome. So what do we got cooking here? I see we are printing chocolate. Yeah, so we've been developing a chocolate printer over the last five years. Most recently it was my senior design project, my capstone project at the University of Pennsylvania and now I'm working on it full-time since May. You've got some really cool prints here. We have a Benchy, we have an Einstein there, and a vase, and everything is, you can eat it, right? Yeah, all completely edible. So how does it work? So basically the chocolate all starts tempered in a cartridge. This one is a half-used cartridge. It goes into the printer. It has a dual heating system to keep it to a tenth of a degree precision in terms of temperature and then it extrudes the chocolate using air pressure and it solidifies it immediately because the whole thing is actually a mini French. So it heats up, it gets extruded essentially, and then it solidifies because it's so cold in there. That is sweet. So what made you do this? I actually started this in an intro to engineering class in high school. I at that point thought I could build anything and I didn't realize how hard it would be to work with chocolate. So I started working with chocolate and it's just been kind of a passion project on and off for the last five years and I've been working on it I guess seriously for the last year and a half. So is the printer your design or is it something you kind of modified? No, it's a completely custom printer. There's a lot of weird tricks to make it work with chocolate and so building it from the scratch, from the frame was really helpful to get insulation on all the edges and something like that. So is this something that you're going to open source or sell or anything like that or is it just just for your project? So we're planning to put together a printer to sell sometime around mid next year so definitely working towards selling the printers in the long term hoping to sell the printers to chocolate shops bakeries and caters for the you know ultra custom chocolate design so if you can scan your face from your phone in 10 seconds and then print it out or put it out to make wedding cake toppers that are just you know very custom and chocolate fully edible really high quality Belgium chocolate but the first version of the printer before going for some of the food safety certifications will be a hobbyist for the hobbyist market. So that brings me to another question so obviously you're giving samples away right? So you had to be like certified food safe or whatever so there you go he's the food safety license right over here so what did you have to go through to do that did they think you were crazy? So for that license I was I have everything I'm giving away this weekend prepackaged in a commercial kitchen so this license wasn't as challenging to make the printer food safe they I have to I'm not I'm not there yet with this design but I need there to be no screws at all in the build area which is the food splash zone and it all needs to be you know like polycarbonate and delrin food safe materials and then for the cartridge itself I'm using single-use cartridges and where all the chocolate touches is the medical grade syringe stainless steel nozzle and then the parchment paper itself so that the whole thing stays food safe. That's great that's awesome well that's really cool I appreciate you taking the time with us I'm gonna enjoy some chocolate we're gonna grab some samples right over here but oh yeah I'll be back yeah just joking but thank you so much I appreciate you taking the time and showing us your chocolate printer thank you so much
