Mike Doty organized this topic.

Running Notes

MIT Course on "how to make just about anything"

 

Wearable computing with machines which can integrate circuitry and sewing technologies

Also, check out the Fab Academy.

 

Mike Doty is looking to make an "open source" fab shop in California Bay Area

 

Water cutter is an interesting technology

 

Z-Corp's 3d printer can do burnout.

 

CnC mill

 

Woodsmetal is a really low-temperature alloy.  Used in old sprinklers.  Can use it for low voltage systems to create circuitry printed into equipment.

 

Writing a trace with conductive ink and then plating it into something that is useful. 

 

RapidPrototyper is a 3d addiive printer, as opposed to things which cut parts away from a big starting slab

 

Will we ever be at a place where we just feed stock into a machine and it prins out "stuff" ?

There are too many different kinds of components that need to be manufactured, and you will always have different machines for different kinds of parts and/or materials.  What about economies of scale?

You should buy screws because they are cheaper?  Bump that, eliminate the screws.  If you make cleverly designed objects, you won't need screws.

 

Can most designs be reduced to one material?  The overwhelming response from this group, is no.  Many many things need so many multiple materials.  Try making a pc board with plastic.  It will be bigger.  Your design trade-offs are different.  A spark plug requires specialty ceramics.

 

What are the safety implications of open source 3d hardware?  You use a lot of safety engineering?

 

If I have 500 RepRaps can I compete with a commercial production line?

 

If you're doing something like RF-circuitry then the board becomes part of the circuit because it is fine-tuned.

 

Kovia is doing rapid prototyping for transistors.

 

It should be rapid prototyping not rapid manufacturing.

 

 

 

 

Software

Salad works is a good software

Blender can export STL files but it is not very good as a CAD, it is more for things like 3d graphic artwork

ShopBot and FabLab both have opensource software products

Others include Omax, MasterCAM

NIST has good open source gCode stuff available

 

 

Weird Materials

Chocolate

Sugar

Pasta (Fabaroni)

 

What available resources are there for free parts models

Squid has many 3d models in 3ds

RepRap has many available bloggers around
