Re: strength vs weight in 3d printing

A story circulated that Boeing had developed a landing gear part entirely with CAD, done the finite element analysis and somehow arrived at the part having only the metal needed to do the job a...

Re: strength vs weight in 3d printing

There's also the issue of scale, maybe granularity. if you want to make small components, you have to face the fixed size of the filaments. It may be that 3d printing isn't suitable for every part. I'm tossing all of this around because I'd like to identify blind alleys before I spend more money. As...

Re: Micron All Metal Extruder Upgrade

Steve, I'm very impressed with your handiwork and certainly with the metal extruder. Obviously it's very nice and certainly more substantial, but beyond these somewhat aesthetic considerations, are there any real advantages to this change? I should add that it is my nature to do things like this, bu...
