I wasn't able to find much about this quickly. It appears some of the 2017 sales were moved to 2018. Seems I remember that although sales are good that profits aren't so good yet, but promising.
Maybe this is best for the 3D/Additive board that Charlie moderates? Also, for comparison, see Charlie's post #48 from last year on that board. SLM is clearly growing but I don't think they are profitable yet.
