Given how often we talk about news in the rapid prototyping industry, mainly about how we can get faster mini-masters , but also in regards to our other project discussions, why not a 3d-printing or similar material/technology thread? At least a common place we can post the links so they don't get buried or scattered in our other threads. Feel free to share your finds here.
First contributing two stories of recent interest:
The idea of 4D printing. That is, objects that change form and dimension after their initial production.
And This; new development in faster almost-seamless 3d printing...or rather extrusion? There is more info on the company page in the description.
So far I've used Shapeways: www.shapeways.com/ which is okay for 'rough' work when it comes to 28mm scale miniatures. It does not produce very smooth results as the highest detail material they have is FUD (Frosted Ultra Detail) with a resolution of 0.1mm.
But I am also considering using these two services because they have a web interface and may be easy to use;
I had a email from stratasysdirect.com, and their PolyJet HD has a 600x600 DPI X and Y resolution, and can put down layer at 30µm (not the maximum of 16µm) and can accurately put down details (emboss/ engrave) at 0.025mm, which is 4 times greater than Shapeways 0.1mm for Frosted Ultra Detail. Here is an image they sent of a raptor (?) which is apparently 35mm long;
Raptor - 35mm long
The teeth look pretty good!
Prices; I uploaded the lower wall section of my floor tiles (and it's solid) to Safeways and it came to €99.27 with VAT (€82.72 without VAT) in frosted ultra detail. The same .stl file (well nearly the same have to scale it up to make it correct) was sent to;
materialise-onsite and using the Polyjet with VeroWhitePlus material it came to £48.00 for one (no VAT), and £39.00 each for 2, and £37.00 each for 3, and £35.00 each for 4 (and £35.00 is the lowest it will go).
stratasysdirect.com and again using the Polyjet but at HD, with VeroGray it came to $122.00 for one (no VAT), $118.00 each for 2, $116.00 each for 3, $115.00 each for 4 (and $115.00 is the lowest it will go for each part).
Sorting this out into $ for easy reference;
Price each no VAT
Frosted Ultra Detail
Notes: all have decent user interfaces, all can be ordered online (though materialise-onsite and stratasysdirect have the option for manual quotes, and stratasysdirect has the option to talk with an engineer (I've heard back from them).
materialise-onsite has multiple language and currencies.
Don't forget to add VAT etc.
As you can see the materialise-onsite price is pretty good value (if it turns out to be as detailed or better than Shapeways), and the price drops down a fair bit with multi-buys. I've place an order with materialise-onsite so we shall see. I will try stratasysdirect, even if materialise-onsite works out, but I might save them for the very final version to be sent to Ed and use as masters.
On stratasysdirect the price difference between Polyjet and Polyjet HD is only $12, so $110.0 for a single part would be a direct match (I think) to the materialise-onsite price of $71.4. I have a feeling that materialise-onsite has much lower settings, but we shall see!

Excellent info Philip, thanks.
There's this US chain of workshop places that opened up in our city about 2 years ago, called Techshop . Basically you can get certified with their equipment, take or teach a class, and "rent" their facilities. Each location may vary in what they offer. I need to get in touch with the local one, as they seem to offer basic 3d classes using makerbots, but their parent site suggests that they also use ProJet HD 3000 HD which according to those specs, has a resolution quite on par to printing mini-masters. Advantages being, I could see the quality of the print on-site, and minimize S&H if stuff is ever sent to Ed's way. Might there be similar places in your countries?
This is also something to consider, but it will definitely depend on personal experience and location: www.makexyz.com/ Basically you get in touch with people in proximity to you who have printers, prices seem to be per cm3. For instance in my area, a lot of the people listed have printers that can get to .3mm to 1mm layer thickness (so larger, simpler detail stuff); but one individual appears to have a form1! I just missed an event with the techshop people, where that person was printing stuff

I see photobucket has wrecked everything for everyone sigh This one slipped by me. I've been watching the kudo3d company for their formlab Titan alternatives, but it's cool to see prices dropping for fairly decent in-home prototyping models. It's not 25 microns quality and it's still $1200, but I guess it's progress. 3dprint.com/176829/bean-3d-printer-kudo3d/
