IDC forecasts that worldwide spending on 3D printers, along with associated software, materials and services, will reach $28.9 billion in 2020, compared to an estimated $13.2 billion in 2016. It’s expected that the manufacturing industry will control the market for the foreseeable future, responsible for more than two thirds of the revenues in the space. IDC believes, however, that medical companies in the U.S. and Western Europe will push healthcare into the number two spot by 2020 with revenues of more than $3.1 billion.
