Comment Re:Really weird backward step (Score 1) 134

If your commentary on welding is referring to the fillets, I believe they are there to prevent a stress concentration due to the sudden change in geometry. I further suspect that the beams are non-prismatic because it is harder to model that way. If what you want to do is prove the capability of the 3D printing process, it is quicker to copy a known good design. Once they get their legs they will likely start re-thinking the basic shapes. Hopefully by then, calculation methods will have caught up enough so that you don't waste a lot of time trying to define all your little non-round, non-straight, non-uniform thickness jiggery-pokery.

My concern is quality control and (more specifically) material anisotropy. 3D printed parts are essentially all weld. I don't want to have to resort to (expensive) welding NDE over the entire part.

Most of the "3d gun" nutters are specifically printing the lower receiver. Under US law, this is the only part of the gun that is licensed. The rest of it is all accessories. What these nutters are doing is printing the unlicensed receiver and then installing regular gun parts around it. In clear violation of the law, I might add.

The entire premise is wrong. Why should some customers have a secret handshake that grants them reasonable levels of customer service? Why can't everyone get this level of service? Or, more to the point, why doesn't everyone get this level of service?

Yes, actually. There is a niche in the logistics business of moving pallets from where they are unloaded to where they are loaded. Also, as others have indicated, there are cottage businesses associated with refurbishing and recycling damaged/end-of-life pallets.Some are just stacked. Fancy operations will strap them into pallet sized cubes.

Slow down sparky. The First Amendment doesn't have the "In order to maintain a well regulated militia"-type clause.

Moreover, even thought the First Amendment clearly forbids Congressional abridgment of the Press, the Supreme Court has allowed multiple exceptions.

So. Take your pocket copy of the Bill of Rights and put it back in your pocket. Grownups are talking.

Oh, so there you are!
