This was a joint 3CL/Cambridge Private Law Centre event. Additive layer manufacturing, better known as 3D-printing, is a manufacturing technology which has been evolving steadily over the last few decades, and has now advanced to the point where it can make the leap from niche technology to mainstream application. Its potential is such that it could change where and the manner in which many types of goods are produced. An interesting aspect of 3D-printing is that it allows for the unbundling of the production process. In this paper, I intend to explore what this could mean for the laws on the humble contract for the sale of goods, and whether the potential of 3D-printing requires developments in the law.
