@reducedAircraftFactory and @Carlos2k10 I am not seeing the same issue as you are with the HP MJP pricing. Yes others (competitors) are offering the same product and are doing it cheaper than Shapeways. This should be addressed, it looks almost like we Shapeways told themselves, "We did Premium at 2X the price and people bought it, HP MJF should be the same price as Premium." I also enabled it on most models in my shop and I am seeing a steady growth with about 10-15% of the people buying the HP parts. I am sure that number would be much higher if the pricing were better. Every model that is available in my shop with Professional Plastic has a short paragraph noting the difference in finish and the increase in strength compared to Versatile Plastic. For most people that is enough information. I also have a model or three (can't recall exactly) that are only available in Professional Plastic. It is just one of those things that I have reconciled myself to doing, educating my customers on the available options. I think Shapeways does a generally poor job of explaining why you would want to use one nylon over another. A single sentence or two on the material properties page is not sufficient to educate the customer base.
