Hi, Brian. Great questions. I'll go one by one. First of all, PolyJet and FDM are our core technologies and we built our entire knowledge of polymer chemistry based on them and we are the leader in both technologies, just to make sure that we are starting from the same page. And both those technologies will grow. But by definition, PolyJet is a rapid prototyping technology, the best rapid prototyping technology because it's full color, and you get the best parts. But it's…still we need to educate the market to adopt it, because most of the market is still single material. And we have the multi material capabilities and the color capabilities. And actually we invented it. And I believe that there is a long runway also for PolyJet. If we look at FDM I already related to it, FDM is one of the best technologies mainly to aerospace. And we are going to focus on engineering, on manufacturing of tools, that's what we call jigs and fixtures, tooling. And on manufacturing, high end part because the mechanical properties are very good with composites with our machines. And we focus on those three segments, so engineers with FDM, high end prototyping with functionality, or tooling, jigs and fixtures. And the third segment is manufacturing, mainly aerospace and auto where you need the good mechanical parts and lightweight. So this is FDM, still long runway to develop it and to make it the manufacturing machine. And that's what we are doing in our pipeline, that’s the upgrades that we mentioned. Now if I look at longer series of production, on production, on manufacturing, powder-bed fusion and VAT, has clear advantages on the mechanical properties on the speed and the cost per out, because it's a production machine. And then therefore, we decided to get into power-bed fusion. As already mentioned, it's a unique powder-bed fusion because we believe we will have the best part quality in the industry. And on SLA, I would relate it as a VAT in general and we believe that there are clear applications that VAT is the most suitable solution for them. Like for example, molds, like specific parts, for example, also in aero for example, where you need part that is more, it's not that the weight is not so important, but the strength is more important. And those specific applications, this is the whole story of the strategy. We want to make sure that in polymer, we are covering all applications; and we'll go application by application to make sure that we are bringing the full solution to our customers. That's the story. I hope I answered your questions.
