This is Surprisingly Cool! - Super Strong 3D Printed Dowel 

that directional "grain" of the printer lines, is what I am going to see about using in home made plywood at some point once my lumber mill is done being built, *where the sheets of plywood are in 2 dimensions criss crossing per layer, then holes drilled through and dowels are pressed into the whole sheet from front to back to make a 3rd dimensional cross linking of the fiber direction for resistance to splitting down it's sides.*

I wonder if the sintering method where you pack the 3D printed item in sand or salt and then toss in an oven to heat up to the melting point so it fuses completely together is nto a better option to super glue, since the cyano-acrylate is much more brittle than even the PLA is.

an international audience has little to no idea how much a stone weighs. metric metric metric metric.

if you watch your video here, Luke, you will see the bar bending a bit too where it makes contact with the dowel XD

Hi, Luke! Have fun in school.

Why make tiny parts? Because they print fast and you can print a bunch at once once you get it where you want it.
