HPO, we hope your model is coming well, any news. What will this model be used for besides trade shows and experimentation. It would be of great interest to us to know if the model will have longevity or if the materials have a short life span. Will the polymer hold up? How will sunlight affect it? Thanking you in advance for any info you might provide. We have a vested interest it this model becoming a tangible object occupying height, length, width, and time (the more the better).
Thanks again.

I haven't begun with building the model yet, due to the rush at work. The machines are totally filled with customer parts the last weeks, seems like every designer wants to have his parts before the holidays.
But this coming weekend it looks like I have some space, I will start with the main arm on a Stereolithography machine. It's going to be build in an ABS like resin
Resin SL7580 on a 0.1 mm layer thickness.
The total lenght of the model will be around 68 cm / 26,77 inches from the tip of the main arm to the tip of the shorter appendage on the opposite site, the main ring will be 15 cm 5,9 inches in diameter.
So it will not be a very big model, but I have to keep an eye at the costs involved to make this model, I will make a post calculation when it's ready but you must think in thousands of Euro's/Dollars for a completed and painted model when I had to build this for a customer.
As an example, we where building a series of 50 USB sticks for a design company, all with different logo's and different spraypainted finishes, from high gloss to to a soft touch paint, that order was in an amount of 11.000 Euro's because of all the labour involved.
Apart from being used at trade shows and photo experimentation, there isn't much else it can be used for, apart from looking good in my office of course

The longevity can be a problem with this model, particularly the appendages, STL resins will bend under it's own weight at a longer time span and stay bend when it's not supported in some way or the other. But the ABS like SL7580 resin is the best choice in that regard.
I will use metal wires over the full lenght inside the arms to support them, the main arm has 4 wires anyway.
Sunlight will indeed affect the material because of it being a photopolymer, the UV wavelenght will make it yellow and brittle over time, but the model will be spraypainted so it's protected against UV light.
When you have more questions, please ask, I'll try to answer them.
