Sorry, did not fully comprehend your post. Are you saying arcam has patents that apply to laser and can be used in dual laser and EBM capacity to promote more uses and efficiency??? Are you saying others have such patents and might compete with Arcam. If arcam, where are the dual uses, what sector, and what is and approximate numerical demand. In short, what was the thesis of your post and its arcam impact. THe post was too vague for my comprehension, sorry
