Lawmakers should keep hands off 3D printing, BYU-I professor says

3D printing uses liquids, power or sheet material to create an object from a CAD drawing.

This is an interesting article from TechCrunch written by Rick Kelly, an adjunct political science professor at BYU-Idaho, about 3-D printers and the issues they may be likely to present, especially when it comes to the Internet.

With 3D printing, also called additive manufacturing, the machine takes data from a CAD drawing and creates and object by laying down layers of liquid, powder, or sheet material. These layers, which correspond to the virtual cross section from the CAD model, are joined together or fused automatically to create almost any shape or geometric feature.

Kelly's concern is with the possibility of laws to restrict the manufacturing of firearms and drug using 3D printers, and the Internet freedom implications of such laws.

For those who appreciate the internet because of its democratizing effects and freedom, I believe the choice is clear. We should decide now that we will oppose any law that attempts to undermine freedom on the internet, no matter the consequences.
