Dear Glyn and List
I assure you there is no need to laugh just have a look at this web page http://www.microtec-d.com/ These guys have really grasped the nettle and are building in 1 micron layers!!!!. The Following is a quote from their web site
"The component is built up in steps of less than 1µm and a resolution of less than 10µm. The component size is currently limited to a maximum of 35mm³. "
I have taken the liberty of attaching a few photos to this mail (once again from their web site so I hope they don't mind) for you all to look at.
I think EPFL have a similar system and they display a RP model of a Porsche about 3mm long. Unfortunately I can't find the web site this morning so have a dig around I assure you Its very much worth the effort.
Also Dr. Bill O'Neill and myself at the University of Liverpool are about to start a project on micro RP which you may be interested in. We would be happy to discuss industrial liaison with companies on this project.
Thanks

Subject: How fine can you go?
I wanted to pass this along for the RP community to comment on. It appeared today on the model making list. I am guessing that it is not possible. If you make the assumption that they are going to investment cast a metal part, would anyone have any ideas? Here is the post:
Has anyone come across any new RP machines with build levels smaller that the Sanders machine? The Sanders has a Build layer: 0.0005 in. An engineer came to me with a upcoming project that will have small channels for a medical instrument. Micro Fluid Dynamics is greatly affected by the steps left behind. Believe it or not he is looking for one in the 5-10 microns. (This is where you might be tempted to laugh)
Sincerely,
