Note: Much of the following was excerpted from Wohlers Report 2017.

The following chart shows how organizations are using industrial additive manufacturing systems for a range of applications. The information presented in the chart came from the survey question “How do your customers use the parts built on your AM systems?” The respondents consisted of 61 manufacturers of industrial AM systems (those that sell for $5,000 or more) and 100 service providers worldwide.

The survey results show that companies use AM technology to produce functional parts more than anything else. This represents the degree of interest in AM machines and materials that produce strong and accurate parts. In the future, we expect the demand for these types of parts to increase much further, especially as companies adopt AM for production applications.

Growth in AM Patent Applications

Note: The following was co-authored by Ray Huff and Terry Wohlers, both of Wohlers Associates. John Hornick of Finnegan collected and assembled the data for the chart.

A key indicator of innovation in any industry is patent applications. From 1996 to 2013, the additive manufacturing (AM) and 3D printing industry experienced a moderate but steady increase in published patent applications. From 2013 to 2016, the number of applications grew by a surprising 7.7 times, as shown in the following chart (taken from Wohlers Report 2017). The green line shows published patent applications, while the blue line shows issued patents.

In recent years, several AM foundation patents have expired. As these AM technologies mature, and new players enter the market, companies are pressured to differentiate their offerings. Filing a patent can be time-consuming and costly, and it can take years for a patent to be granted. This makes the number of patent applications a good way to take the “pulse” of a particular industry. The AM industry has a strong one.
