When the New York Times wrote of the improved technology of 3D printing this writer responded with a frivolous blog about it, scoring the concerns of anti-gun people about how the technology will allow everyone who wants one to have a gun without government oversight or knowledge. One of those in the anti-gun camp is Josh Horwitz, executive director of the Coalition to Stop Gun Violence, who said that 3D printing is “going to be a big concern. We don’t know how that’s going to come about and don’t know what technology.”
That technology is evolving before his very eyes. The RepRap Project aims to produce free and open source software for 3D printers, including software that allows the printer to produce its own parts. Two years ago RepRap allowed printers to create tiny plastic parts for small motors as well as circuit boards for computers. Today it allows hobbyists to build household items like fully-functional clocks, flashlights, iPad cases, watchbands … and receivers for rifles.
