I did not want to high jack another thread. I basically have seen a few posts about 3D Printed parts and their abilities and I wanted to share our experiences.
We have been using 3D printed parts for the last two seasons. We used them more extensively in 2011 then in 2012 basically due to need. Almost all of these parts are parts that saw a fair amount of load. They were not used as a bracket for a switch or a spacer.
Basically for us it boils down to what to machine or what not to machine. We have the machines and the ability to pretty much manufacture anything we need. Sometimes we just do not have the time or manpower.
3d printer will run all day all night unattended, allowing for other things to happen like sleep.
You do need to know how to design for the machine and the material.
Ask if you have questions, we are open to answering anything.

The solution to that "problem" is obvious: practice driving. - Alan Anderson [more]
