Interesting system. No one knows for sure how things will play out in 3d, but what I can say is that Arcam is much further along in his 5 steps of the hype cycle than some other speculative companies I have invested in such as onvo, sglb, nviv. Arcam is tested, has an established diverse client base buying their machines, is making money, is actively improving their products in conversation with their clientele and so on. There is hype and a great deal of hopeful anticipation built into the stock price, but this isn't a start up phase company early in his hype cycle, its in stages 4 or 5
