Major Patent expired yesterday - SLS (Metal Printing)

[Eddie]

Hopefully we will see more and more 3D printers coming out that use SLS. Unfortunately only one of the patents have expired. There are still several that prohibit what type of SLS printers can be made. Also I'm not sure how feasible SLS printers are for in home use.

I personally question the safety of hectowatt lasers in the household.

I agree you have to use a pretty powerful lasers for those machine and who ever is going to produce one better know what they are doing.

They certainly need a lot of improvements before I would allow one in my home. Perhaps this is why we haven't seen a laser 3D printer for the home created by 3D Systems. They are the owners of the patent that is expired. They could have been creating one of these printers all along, and they are the largest 3D printing company out there.
