14 DAY TRIAL // Dishwasher can mean one of two things: a person hired to wash dishes, or a machine that can wash dishes in your stead. The latter is what a 22-year-old Swedish engineering student has to show.
Contrary to what modern colloquialisms would have you believe, machines don't need electricity in order to be named by that term.
A machine is any tool made of two or more parts which uses energy to perform an intended action. Electrical energy is one option, mechanical energy is also on the list, as are thermal and chemical means.
Thus, the new dishwasher created by the 22-year-old Swedish engineering student named Filip Sjöö qualifies as a machine despite being made fully of plastic.
The 3D printed dishwasher
Filip Sjöö got a 3D printer for Christmas, so he has naturally been putting it through its paces ever since, as any reasonable person would.
He did not just play around though. Instead, he decided to see if he could do something so practical that it could bring a real change to how he lived his life. Or maybe it was just a whim.
Either way, he wanted something that could use the water from the tap, and he didn't mean just a random cup or anything.
Eventually, the young man created a mechanical dishwasher that takes most of the effort out of, you got it, dish washing.
He started from a CAD file of a mechanism that would fit onto the threads of his sink tap. He tried finding one online but failed, so he made his own in SolidWorks.
Once he had the starting pieces ready, he tried to create an internal water turbine, only to give up on the idea when he realized that making one without using seals was a fool's errand (the water pressure caused leaks quickly).
Fortunately, he had engineering knowledge to draw on so he created an external turbine that makes a brush go back and forth one time every second.
Availability
Sadly, this isn't something you'll find up for sale anywhere. You might eventually hear about Headface releasing it or something related. It's a company that Sjöö co-founded, as a basis for his work after he gains his engineering degree.
