During his State of the Union address Tuesday night, President Obama shone a bright light on the 3D printing industry – also known as additive manufacturing – which is an advanced manufacturing and design process for making solid 3D objects from a digital file.
The burgeoning business includes just a handful of publicly traded companies right now, all of which are still small by market standards. 3D Systems Corporation, based in Rock Hill, South Carolina, had revenue of $322 million in the 12 months through September 2012 and a market cap of $3.74 billion. Stratasys, Ltd., based in Eden Prairie, Minnesota, had revenue of $188 million and a market value of $2.9 billion.
Another company in the sector, ExOne Co., went public just last week and is now valued at $358 million, while Proto Labs, Inc. has a market cap of $1.28 billion.
