Copyleft in the 3D printing world
By Tom Callaway

While much of the 3d printing ecosystem is built on proprietary software, there are sections which rely on copyleft licensed works. I will give an overview of where copyleft can be found today in the 3D printing world, and the role that it plays in encouraging the Open Hardware movement.

Monday 12:20 p.m.–12:50 p.m.

3d printing has been around as a technology since the early 1980s, but in recent years, it has become practical (and affordable) for a much wider audience. While patents have had a chilling effect on the space, much of the growth in the ecosystem is the direct result of copyleft licensed projects like the RepRap project. Many modern 3d printers can directly trace their lineage to RepRap, and two of the most popular 3d printer families (Lulzbot and Prusa) make extensive use of copyleft licensed works in their software, firmware, and hardware. In this presentation, I will cover some of the history of copyleft in 3D printing, and give examples of how it is used today.
