Re: Practical 3D printed parts
ABS is a very nice plastic and is very strong. After 3D printing technology improves enough, it will be feasible to start producing things like pulleys and other highly used parts. Pulleys should already be an easy one to 3D print as long as you use an aluminum or steel axle because the load is distributed throughout, reducing the stress on the plastic!
I have gotten many things printed in ABS. They are very strong, and lightweight and take compression forces quite well, as long as there is no sheer or bending force on it. My Stirling Engine crankshaft broke because of the high sheer force I accidentally placed on piece, when removing the building material. I should have used an abrasive instead, to get rid of the black building material.
Our school has either 2 or 3 of those Dimension 1200ES printers! Out of that, we use only one!
