3D printing has existed since the 1980s but is now gaining more widespread adoption. While still mainly used in niche industries like automotive and aerospace, the reduced costs of 3D printing could lead businesses to use it for on-demand manufacturing and customization. This represents a paradigm shift that will impact supply chain models. As 3D printing grows to a projected market size of £4 billion by 2019, insurers need to understand the new risks it brings and work with businesses to provide appropriate coverage for issues like product liability, intellectual property violations, and cross-border distribution of printed products.
