Well, thank you, Mark, and greetings and welcome to all call participants. As Sigma Labs has consistently stated in previous presentations we're focused on overcoming the three barriers and obstacles to the widespread acceptance of 3D printing for metal parts. And those obstacles and barriers are quality, geometry and productivity. As Mark had mentioned INSPECT really addresses the quality aspect and that’s something that we've been working with a variety of top line companies to validate and verify and eventually incorporate into their production. The next major problem really is the geometry and although additive manufacturing is a computer driven process, digital design, digital manufacturing what you see in the computer is not necessarily what comes out of the machine. And so verification of geometry is critically important to ensure compliance to a print and to really guarantee that the as built model is what you see in the CAD or the should be model. So DEFORM solves this problem by looking at sensor data so we’re looking at data from the actual build as the part is being made and you can imagine essentially looking at cross-sections of the part as it’s being laid down layer by layer, we’ve verified compliance and then we’re able to take that and compare it to the CAD model and to really answer that critical question, is the as build part within the specification of the should be part, do they match? And so DEFORM involves integration of optics, mechanical systems and of course software to put all this data together and to present it to the user in a useful manner that really immediate flags problems. And so it’s a very valuable tool not just for compliance which is its main function but eventually we feel it will be very valuable as well for diagnostics, if something goes wrong why did it go wrong, what went wrong and more importantly where in the part did it go wrong. So, that’s DEFORM and if we now go to slide five how does this link into the overall quality strategy. And so again there is really two aspects, number one is quality, did I meet the requirement, and then second part of that is delivery, can I ship the part, have I met the objective evidence of compliance to the design intent. And so what are the key elements of this overall strategy? Number one, we offer a third party platform which is very critical because in manufacturing what you really want is an independent yard stick to measure quality, independent of the machine that made the part. And that’s a very widely accepted principle of quality assurance. You need an independent measure. The second part of this is looking at process control, not just based on knob settings on the machine because if you take five different machines they’re all going to have different settings. Looking at what’s really going on in the process is critical and both DEFORM and INSPECT establish a process window based on the in process dynamics not just the knob settings on the machine. But at the end of the day none of this makes any difference at all if we can’t meet the properties because at the end of the day quality is defined as does the part meet the requirements in the intended end-use environment whether it’s going into a jet engine, an automobile, whatever it’s going into, can it meet the requirements, does it have the properties, does it have the right material micro-structure, can it perform? So, the linkage between what’s going on as the part is being built to the final properties is another very important aspect of proving quality. And again INSPECT and DEFORM are designed from the ground up to address these sort of linkages and these issues. Lastly, we’re working in an area which is very regulated, biomedical implants would be regulated by the FDA, aerospace components would be regulated by the FAA, and similarly there is lot of regulatory oversight in some of these critical metal parts. So, part of the delivery aspect is the reporting and the compliance and the ability to provide objective evidence of compliance. So that’s a very important aspect which enables our customers to sell AM parts more readily and to overcome and anticipate any regulatory issues or hurdles. And what does this all mean in the final analysis, shorter qualification time, faster time to market for AM parts and at the end of the day it is all about cost. Currently, it can be as expensive to inspect the part as it is to make a part and often that multiplier can be greater than one, it could be twice as expensive to inspect as opposed to make. And so both DEFORM and INSPECT in the final analysis for our customers would really address that cost issue. With that I’ll hand it back over to Mark who would continue and discuss some of the further plans for 2015.
