The 3-D printing industry has been on an absolute tear over the past year, with several initial public offerings and numerous all-time highs for companies in the industry. The most spectacular example of optimism in the industry can be found in voxeljet's (NYSE:VJET) recent IPO. This 3-D printer company's shares rose more than 100% after its IPO. So just how do investors in this hot sector determine which companies are the most expensive to invest in?
When we look at the crop of publicly traded companies -- which include 3D Systems (NYSE:DDD), Stratasys (NASDAQ:SSYS), Arcam (NASDAQOTH:AMAVF), ExOne (NASDAQ:XONE), and voxeljet -- it can be very difficult for average investors to determine just how much they are paying for these companies. At first glance, it appears voxeljet is more than twice as expensive as its competitors, but given its growth rate, is it still the most expensive?
