3D Printing Services
The consumer market for 3D printers has grown tremendously over the past several years. According to Credit Suisse the growth in 2013 is 100% vs. 2012. Consumer 3D printers allow the households to produce certain goods at home. Since most people are not CAD professionals, they have to use third party designs. 3D printing marketplaces are the largest sources of 3D printable designs and it is believed that they will dominate on the market of 3D printable objects.
