A recent study has found that drinking between three and five cups of coffee a day is associated with an overall lower risk of mortality, lowering the risk of premature death by up to 15 per cent. That’s great news for coffee drinkers, but if you’re looking for an even better excuse to start brewing, look no further than 3D printing. Instructables designer Jonathan Odom (better known as Jon-a-Tron) has just revealed the designs for this beautifully crafted, radial, six-flask cold coffee brewer, made from 39 different 3D printed parts. Whether you’re a bonafide coffee connoisseur, want to share the aforementioned health benefits with your friends, or are just in need of serious jolt, this 3D printed cold coffee brewer will surely elevate your morning routine.

Previously, Odom, who works at the Instrucables Design Studio, created this 3D printed cold coffee brewer, capable of producing one perfectly-brewed cup of joe. His latest design, however can brew six cups at once, meaning you can taste-test six different kinds of beans, or make enough for all your friends.

“Most of the large batch slow drip cold brewers I’ve seen use a large volume of water and drip into a large volume of coffee,” explained the designer. “This clearly makes [economical sense] and simplifies fabrication, but I liked the idea of being able to brew multiple kinds of beans at one time. Like wine snobs, coffee snobs have provided us with a wide variety of flavor profiles and if you pay attention, you’ll notice drastic differences in the taste of one bean from another.”

He began by creating the pieces in Fusion 360, his ‘go-to’ free 3D design and CAM software. He then uploaded the STL files to Autodesk Print Studio to get the desired orientation, and finally 3D printed them in white PLA filament using the Dremel 3D Idea Builder. “This is a large project that includes 39 3D printed parts, so be patient!” he advises makers. “Orientation is very important for getting good results. I find it's a good rule of thumb to find the largest flat area of a model and rotate it so that it's in contact with the build bed.” The 3D files are available for download in both F3D and STL, and while he chose the Dremel 3D Idea Builder, he advises any desktop FDM 3D printer would work.

Once everything was 3D printed, Odom assembled the rest of the parts, which include boiling flasks, silicone stoppers, needle valves, filter funnels, wooden dowels, and copper tubing. Once combined, the result is a fully functional and completely gorgeous coffee brewer.

“I explored the idea of making a linear one (the all-to-common setup at your typical hipster coffee bar), but I thought a radial design would have a nice effect, and would also make the brewer more of a centerpiece,” explained Odom. “After all, the whole point of taking all this time to design and fabricate the thing is to draw attention to it; to make an event out of the slow process of cold brewing.”

His design process certainly paid off, elevating the everyday task of brewing coffee to a downright artistic experience. “This piece gets a lot of attention at the office (people have been calling it the coffee space ship), so it's a success as a performative centerpiece. The coffee tastes great too,” he added.
