"The market for 3D printing in 2012, consisting of all products and services worldwide, grew 28.6% (CAGR) to $2.204 billion, according to Wohlers Report 2013. This is up from $1.714 billion in 2011, when it grew 29.4%. Growth was 24.1% in 2010. The average annual growth (CAGR) of the industry over the past 25 years is an impressive 25.4%. The report goes on to say that the CAGR was 27.4% over a three-year period (2010–2012). The 3D printing industry is expected to continue strong double-digit growth over the next several years. Wohlers Associates believes that the worldwide sale of 3D-printing products and services will approach $6 billion by 2017, and $10.8B by 2021. It took the 3D printing industry 20 years to reach $1 billion in size. In five additional years, the industry generated its second $1 billion. It is expected to double again, to $4 billion, in 2015, according to Wohlers Report 2013."

3D scanning and 3D printing can be viewed as flip sides of a coin. 3D printing enables development and manufacturing of products that can be highly optimized for the preference of users, while 3D scanning allows effective and accurate understanding of physical products that are becoming less standardized and more customized.
The customization and individualization of products is happening not only at retail level, but also at industrial level, for example, in the Medical Implants and Consumer Electronics spaces. It is believed in the Medical Implants industry that full customization of medical implants will come in the next few decades. This trend is supported by the technological and economic advancement of additive manufacturing, hence enabling a cost effective product development cycle for customized manufacturing. Such macroeconomic trends in manufacturing will shed increasing emphasis on 3D scanning's advancement not only around its affordability, but also its technology, particularly on the scan duration, which creates the key limitation within 3D scanning's applications to mass manufacturing.
