Conventional wisdom would suggest that the 3D printing materials market is going to be directly tied to the 3D printing hardware market. As the rate of 3D printers sold every year continues to increase, so too should the materials used by those printers grow at a similar rate. However, in actuality the rate of growth for the materials sector will grow exponentially faster than the hardware market. Materials are consumables, so they will need to be repurchased regularly provided the 3D printer is being used regularly. While the materials market has been growing in the past few years at a similar rate to the hardware market, that was primarily because consumables were being purchased by the smaller desktop market, where usage is often less frequent than industrial or commercial markets.
