Fwd: [thingiverse] fast cure plastics & 3D printing

The future is closer than you think... just use lasers, no sharks required.

Can't wait for the LaZerBot :-D

The commercial perfactory systems are $130,000 or so. These new homemade versions are less expensive than a Thing-o-Matic!

http://www.robhopeless.com/
http://3dhomemade.blogspot.com/

Photocurable resins are more expensive but they also provide the highest possible precision/resolution because its photolithography.

on each of the other points, i have slight experience with a couple of these FWIW:

1) for electrospinning or really electrospray is what you want i think, the size of the particles is easier to control than where they go (they go absolutely everywhere). you'd need a highly highly focused electrical ground to serve as the catching focus. very difficult. usually people just use a 4" square plate, but it catches particles even on its backside. electric fields are crazy but i love them.

2) piezo oscillators are hard to make go perfectly up/down for cheap. a buddy at the hackerspace made one last week with some audio transducers and a perfect tone generator but the vibrations tend to have slight lateral motion at the nozzle which causes particles to eject sideways sometimes. But that was only a $15 setup. =D

Hi ALL,
We have just released a new OpenRISC-FPGA-development board that is
specially designed to match OpenRISC processor SoC designs. The board
supports the most common/wanted interfaces, with a small physical size
and easy connections/debugging solution. We offer this powerful board as
a low-cost FPGA development board, back to the community.
We have also created a new VirtualBox-image with all OpenRISC tools
pre-installed and with detailed HowTo-guides, focusing allot on making
sure that all users can get started easily using the OpenRISC processor
FPGA designs together with this board.

Our mission with this board is to spread the OpenRISC processor
awareness and hopefully get more contributers into the project. We sell
these boards via OpenCores-webshop at self-cost.

Want to buy one? Then go directly to the webshop:
http://opencores.org/shop,item,9

Download the NEW OpenRISC-Ubuntu-VirtualBox-image:
http://opencores.org/or1k/Ubuntu_VirtualBox-image_updates_and_information


So join the OpenRISC-project,
 / ORSoC-team
