Currently, 3D printing’s largest applications are for making prototypes, molds, and tooling. Direct production of end use parts, however, is beginning to grow in industries including aerospace, medical, automotive, consumer products, architecture, and electronics. Leading 3D printer companies’ razor/blade model could inhibit growth, but emerging third party material suppliers and equipment manufacturers with more open models are beginning to challenge their dominance as core patents gradually expire. In addition, emerging intuitive design tools point the way to more efficient part design. This report forecasts the future market size of 3D printing and finds that materials, printers, and parts will total $12 billion in 2025.
