Hi All

Only came across this forum today as i'm really interested in building a 3d Printer.
Is this topic still active as nothing has been posted since December. Read all 240 posts and some great information. Has anyone made any progress on a supplier for Teflon AF2400 or a similar product?

Hey Hughes,

I have actually seen Joe de Simone present his company at Hello Tomorrow in Paris. I believe it is not wise to create a printer with Teflon AF and a DMD light engine. The main problem is that you are under patent. You wouldn't be able to sell your machine and most likely it is much more cost effective to buy Carbon's machine when it comes out.
You could try to get the same result with a different combination of layer and light engine. I have been thinking of using Teflon AF and a transparent polygon scanner.
In CLIP, the part concurrently advances away from the DMD projection which minimizes stair stepping and enables the production of flexible parts. With a transparent polygon scanner, the refresh rate is so much higher that it might be possible to keep the part static. If the part is kept static and the pixel information is rapidly altered, an exposure area of fluid, typically a polyurethane, can be modified as it grows towards the Teflon AF. Before the light solidifies the so called "deadzone", the scanner moves to the next area or pixel. Another option, would be to expose a full scan line multiple times and alter it as it grows toward the Teflon AF. Before the line solidifies, the so called "deadzone", the scanner moves to the next line. Finally, a combination of the above i.e. exposing a line multiple times and changing the pixel information might be option. Some more information on coating are outlined here recoating.
These strategies should can be used to go round the patent. I would explore these if you have the time. At the moment, I am working on the transparent polygon scanner.

i try to make polygon head i hard but is best for 3d printer lock on the 3sp printer you will se is good that way the evisiontec made it. ... -printers/
