Hi Just joined forum. About 3 years ago, I came across the 3D print technology, and did some research... long story short, I just finished building a CNC router, that will cut plastic, wood, aluminum and most softer metals... the 3D Printing is an additive process and the CNC milling is a subtractive process. My CNC can be fit with an extruder that will make it become a 3D printer. During the build process I bought a Milling machine and a Metal lathe... I've been teaching myself to use both, and it enabled me to finish my CNC build.... In the 'Real World" I'm a Graphic Designer / Artist, so these abilities helped alot with the 3D design CAD aspect of the process. I haven't done much with it yet, but I should be able to develop pretty much any part I should need ( taking in trial and error of course ) I'm keeping an eye on the 3D print technology... and the prices are coming down as the quality increases. It's very exciting stuff for all DIY'ers... they day is fast approaching, when you will need a part... and simply sownload the File ( or even the G-Code ) and 'Print" the part in your own shop.... Imagine the market for "Custom" work!!! it's a manufacturing revolution that's gonna be huge!... and coming fast.
