A project to investigate the market for materials that may be used in 3D printing, understand the market needs and define options to accelerate participation. IDTechEx established a list of companies to interview based on existing knowledge, desk searches and conference attendance. We leveraged our network, visibility, sales team and also event organisation to arrange interviews. Our topic experts and consultants carried out the interviews, and compiled, analysed and presented the information. IDTechEx highlighted and analyzed the drivers and restraints affecting the entire 3D printing industry and also specific areas of interest. The segment-by-segment focus is crucial because different 3D printing methods and applications will have different market dynamics. Here, external trends, drivers, barriers and other parameters will be identified and fully assessed. Accurate and importantly up-to-date market breakdowns by applications and material types were developed for this fast-changing space. IDTechEx benchmarked competing solutions and material options using material properties and processing parameters, as well as other factors such as technology readiness, cost, and availability. IDTechEx estimated volume demand for materials by end use or application, segmenting the market as much as possible, covering automotive, aerospace, medical, dental, home, consumer products, and construction.
