This DIY electric coffeemaker prototype uses an assemblage of 3D-printed parts and cast aluminium. [siemenc]‘s main goal with this project was to utilize and demonstrate recycling and re-usability. He used Filabot filament exclusively and melted down scrap aluminium such as cans, foil, and CNC mill waste in an oven he fashioned from an old fire extinguisher. He also cast the aluminium parts himself from 3D-printed positives.
Of course, he had to buy the things that make this a coffeemaker such as the hoses, the fuse, and the heating element. If you’re wondering why he didn’t salvage these parts from yard sale machinery, it’s because he wanted to be able to replace any part of it and have it last as long as he needs it to last. The innards he used are not specific to any model, so he should be able to easily find a replacement.
Just like a pour over set up, [siemenc] has fine control over the strength and quantity of the brew. We particularly like this machine’s exotic bird looks as well; it may be a prototype, but it’s quite stylish. If you’re looking to go all the way with DIY coffee, why not grow your own beans and then roast the beans yourself?
