As with anything, there is a groove and type for any of these new systems and applications. Some of what ppl know about the current systems is from past knowledge of what was and not what is current. As you have already seen, there is a need for the 510 in your office and I know quite a few different companies that use the 510 in medical, design, and various engineering companies.
You can't beat the cost and time to print plus full color of models created with the 510. You can't beat the flexibility of materials from one machine. People say, "well models from the machine are not strong" once again, that's all relative to what you are doing. Parts can be infused with any number of different liquids to achieve a wide variety of strengths. Plus, name any other process that can create a mold that you can directly cast metals to.
Someone posted about how there is a cost in running the machine and ordering supplies, ummmmm show me a machine that runs itself and calls the company it came from to order supplies and I have a bridge for sale, it only cost $.50 bottom line none of these RP machines is 100% with out flaws, you can't have an SLA/SLS machine in your office with out certain precautions in regards to health issues. (i.e. venting) You have a plastic machine that have support structures that have to be broken off or dissolved in a liquid solution. You have Zcorps machine which some parts may or may not need infiltration.
I have worked in a service bureau for a few years and if you are going to start to out source your machine there are some definite consideration to take into account. If you need some help with this, let me know.
