This is definitely not an article I would have expected to read here. It’s still very interesting though. I wonder if there should be research into harnessing the methane produced by the microbes as a fuel source as well.
This is amazing! If this is achieved it could mean ridding most of the gas that is responsible for so much damage to the environment. Changing the gas to a solid and having that solid be of good use to us sounds like a win-win. Having the National Science Foundation donating a massive amount of money into it shows there’s real promise. Changing the methane to plastics for 3d printers means there could be much more useful materials that could be made from it. Apparently this is just the beginning. I’m surprised methane hasn’t been looked at closer until now since the massive amount in our atmosphere has brought so much destruction. Lets harness it for the good of the environment and man kind. ..And 3D printers everywhere! 😉 ha!
Sounds very exciting
exciting yes, but cost is always the main factor… if it is more expensive than chinese PLA then most folks would still buy cheap filament off amazon instead of locking up the Methane in the plastics.
Lots of plastics are already made from Natural Gas (= Methane), and Ethylene Gas, Propylene Gas etc..
Oils are a major component. Gas isn’t necessarily what is being used for many plastics. There was a similar project announced a couple of years ago that was pretty interesting. https://cleantechnica.com/2014/01/03/needs-tar-sands-oil-aircarbon – I really like the idea of turning waste into usable products. Unfortunately, we also need to be conscious of the waste this will create and how will we treat the off-gassing of these new plastics as they degrade over time and start breaking down.
Is it possible to use a gas (methane) for 3D printing?
This would be a breakthrough in 3D printing without any doubt.
