9:58 thoughts My name is Chris, I am a 3D printing hobbyist from australia. I dont really specialise in anything specific, but 3D printed tools and tabletop accessories are some things youll probably seen quiet often. I do all my 3d printing on a Ender 3, which I highly recommend as a budget printer. Currently I only run 1 printer but I hope to expand that in the future. Recently acquired a photon 0 to do resin printing with. I like to share all my 3D printing ideas for free although I do plan to sell stuff in the future. Most of my projects will be mostly 3D printed with a few non printed components included, these can often be found on ebay. I actually use the cheapest filament I can get for all my projects, again I hope to change this in the future.
I’ve been watching Chris’ lathe builds for awhile. This concrete pour seems like a really useful idea. The lessons learned and advice given here are valuable insights into the practical aspects of this technique.
My main underlying curiosity is what happens when such a methodology is used to create automated single purpose machines.
Concrete lathes are far from a new idea. During WW1, the US needed more lathes than we had. It could take years for a cast iron casting to age enough sitting outside before you could do the final machining to actually build a lathe.
So concrete was tried as a substitute for cast iron. It has some good properties, it cures quickly, is rigid enough, and dampens vibrations pretty well. The downsides are you require a physically larger machine that takes up more floor space, and they are difficult to move making resale difficult, and they don’t last as long in that usage, so they aren’t cheaper in the long run.
Concrete lathes had their day and quickly died out to be forgotten.
