Filter coffee through 3D printed glass | Hacker Day

Usually, when we think of 3D printing, we think of viscous melted plastic or UV curable resin. However, there is a lot of research around printing special impregnated filaments with alternative materials. [Ahron Wayne] has been studying these materials and decided to use prototype prints to make his own beer.

Delicious, but [Ahron] pointed out that you should not drink in the laboratory. [Ahron]’s test subject is the glass-impregnated filament being developed by Virtual Foundry. The filament is filled with tiny glass particles, and the idea is that it can be printed like any ordinary plastic filament. From there, it is heated in a so-called degreasing process, which removes the plastic from the printed matter. Then, it is heated again during the sintering process to bind the remaining glass particles together.

This is a complicated process that will cause the size and porosity of the final part to shrink. However, where some people might see failure, [Ahron] saw an opportunity. The porous printed part is used to filter the coffee, with a little vacuum that sounds like a venturi.

[Ahron] pointed out that this is not a particularly effective method of making coffee, but it does work. We have also seen exciting work on steel impregnated filaments. Video after the break.

Finally, a coffee brewing method that is more complex and pretentious than Chemex. I suspect that I will soon start to see such settings in my office.

For a long time, there have been more complicated and pretentious ways to brew coffee than Chemex. My Bodum vacuum pan does not look as industrialized as in the picture. More film chemistry laboratories require more time to set up than Chemex. I don't want to set it up first thing in the morning. But it looks really charming when brewed.

The combination of its fragility (top-heavy, oddly shaped glass shards without a flat bottom) and complexity means I don't use it often, but it is said to make excellent coffee. I don't know, I drank the leftovers from the automatic drip machine when I cleaned it in the morning.

I like the smell of fine glass particles in the morning

Isn’t silica a permitted food additive? Chemically, it should be harmless...

I think your idea here is correct. I think the paranoia lies in the description of the final composition of the structure. To be honest, I have been working in the coffee and espresso production industry all my life. From roasting green beans to machine manufacturing and maintenance to the final beverage, dripping coffee through the substrate always introduces a considerable amount of contaminants. According to the common operation methods I understand, the espresso made by the real stainless steel head basket is the safest for your body and the least pollution. ! One breaks down much faster than the other. You can perform mathematical calculations on the filter and stainless steel.

An interesting method of making a Buchner funnel, but it is impossible to obtain a precise pore size. It is best to use another filter first, and then use sintered glass as a cleaning step

Oh man, it took me about 30 minutes to decide whether to say "Sounds like a Buchner funnel with extra steps"! Support you, Internet stranger, to prove my paranoia is justified, and others will point it out.

How about using sintered glass as a coarse filter and paper as a fine filter? Dioxins give off a delicious taste.

Wouldn't like it to be cool/fun. Come on, brother!
