Homebrew PCBs

Yea I know some (most?) would like this thread to just die and GO 
AWAY but I'm going to throw in my 2 cents.

(note: Prepare for a LONG  editorial rant )

As far as the way I see the DIY entry level CNC business
and the concept of doing things ourselves going we have gotten to the 
point that we can generally AFFORD to have someone else do it for us, 
so we do that, or BUY something off the shelf that comes rather close 
to what we want. Also considering the number of hours people are 
working, spending time with the kids at T Ball, Little League, 
Soccer, etc. getting second or third degrees (not to mention time on 
the Internet) people don't have the time to learn such things as CNC 
related topics.

If you have a product that is waning in popularity for whatever 
reason, why not step back and look at things on a broader scale. 

You need to DIVERSIFY your product offering.

So many years ago large (enormous) cars ruled the road. Then in 1973,
 The Oil Crisis hit and the smaller imports started poring into the 
U.S. The quality of those cars for the most part was garbage, but the 
people bought them for the fuel economy. The American auto 
manufactures were loosing ground fast, so they started building small 
cars. After a number of years, people adjusted to the fact that they 
would never again see gasoline at $0.53 a gallon (that's what I 
remember paying). People got tired of the cramped econo-boxes they 
were driving and started buying trucks. These days, car sales have 
slumped and `truck' ( PickUps, SUVs, Sport-Utes, MiniVans) sales have 
gone up considerably. Twenty or thirty years ago, who would have 
thought that General Motors would market a PickUp Truck under the 
Cadillac brand? Would you have guessed Mercedes Benz and B.M.W. would 
be selling Sport Utility Vehicles? 
Thirty years ago the basic concept of these vehicles existed, at that 
time they were commonly known as  `Work Truck' or `Crew Truck" and 
were generally relegated to blue color work crews or farms. The IDEA 
or Concept is nothing new! Now these things are EVERYWHERE and some 
could run over $100 K (original Hummer) 

The point is the Automakers constantly DIVERSIFY their product 
offerings.

Instead of complaining that your market share has diminished, pull 
the spindle head off and replace it with some sort of material 
depositing head. Use a low temperature thermal plastic (Friendly 
Plastic from American Art and Clay Co.)in a small heated chamber,
add a small nozzle and a stepper driven plunger.
Another option is to use a two part casting resin in a dual tube 
reservoir with a static mixing tube for a nozzle (Alumilite comes to 
mind but it sets up awful fast).
Even CA glue in a syringe and baking soda for a catalyst has been 
known to be used. 

NOW go out and market your NEWLY REDESIGNED product to mechanical 
engineering colleges, third world developing countries and others as 
a 
3D / STL Printer.

Is this concept new or original? . . .
NO

Do I get to lay claim to you stealing my IDEA?
Not Just NO, But H*%% NO!
