Re: [DIYbio] Re: At home fabrication of micron scale microfluidics

Otto,

for a simple experiment with electrowetting (what the dropbot uses)

John Griessen,

There are many slicers, each do slightly differently, so some might not have those discontinuities.  

Have you tried previewing the gcode layer by layer with something like this ?

Omg, this sugar stuff is so awesome! Thanks for sharing!
By the way, have you already seen this open hardware for microfluidics control!? This is another cool DIY thing to have on a lab that plans go on microfluidics.

The other end, really big 3d objects using fused sugar layers

http://www.evilmadscientist.com/2007/solid-freeform-fabrication-diy-on-the-cheap-and-made-of-pure-sugar/ 

In February we gave a sneak preview of our project to construct a home-built three dimensional fabricator. Our design goals were (1) a low cost design leveraging recycled components (2) large printable volume emphasized over high resolution, and (3) ability to use low-cost printing media including granulated sugar. We are extremely pleased to be able to report that it has been a success: Our three dimensional fabricator is now fully operational and we have used it to print several large, low-resolution, objects out of pure sugar.

That is (almost?) exactly what Jordan Miller did... he used to post on
here more before he became a professor.
