Instapot Distilled Water Capture
Description
WARNING: STEAM IS HOT, USE AT YOUR OWN RISK. Also No idea whether this is ok for medical devices. Only some grades of ASA are food safe, so do not drink the output. I assume no responsibility for the use of this device. Distilled water is occasionally hard to come by so I thought to myself wouldn't it be great to make some at home. Since I already have an Instapot which produces buckets of steam, I figured I could try capturing that steam into a simple distiller by removing the vent/seal knob (This is designed to be removed for cleaning) and fitting a tube to it. The tube I am using is a 5/16 OD (a hair under 8mm) which I picked up from the box store. Copper would be better for cooling the water but this was handy. The fit on your Instapot should be hand snug and the tube should be snug as well. A little teflon tape can bulk up the tube if needed. I have printed this in PETG and ASA. ASA (Pictured) is definitely better because the PETG will soften and deform. Not a big deal, it still managed to keep a seal, but ASA does not deform at all. Its such a fast print that you can print extras if needed. I included my fusion file with parameters for the tube diameter and most of the other important dimensions. Please be careful, the Instapot will not build up pressure but steam burns are not fun. Let everything cool down before removing it. I put 4 cups of water into the instapot, seal it, and fit the tube and adapter on the top. The extra hose I drop into a bucket of water with ice to act as a cooler. I put the end of the hose in a cup to capture the distilled water. I then run on manual for 15 minutes. Takes about 2 minutes for steam to start. Enjoy!
