I am such a newbie that my questions may not be as relevant to you as they seem to me, so please give me the courtesy of an straight forward answer if you can, thanks.
Question #1. After visiting Stratasys I find myself leaning toward FDM & Nylon 12 materials for my product idea. Is anyone here familiar with the strength of those materials? At the Stratasys website they show a pic of a shovel handle and mention the following,
"FDM & Nylon12 Nylon 12 parts built on a Fortus 3D Production System are the toughest in the industry, exhibiting 100-300 percent better elongation at break and superior fatigue resistance over any other additive manufacturing technology. Nylon offers the best Z-axis lamination and highest impact strength of any FDM thermoplastic, as well as excellent chemical resistance."
Hoping that someone or more have had some experience in order to share how strong these materials are. I am trying to achieve close to the tensile strength of .030 stainless in a pulling force. These look like they might come close.
Question #2. Does the cost of these materials and the use of a Fortus 3D Production System reach deep into shallow pockets?
Thank you

Man, lots of fail in this thread.
Jerseygirl: You can print Nylon 12 in FDM, on a Reprap or any other consumer printer.
Investrite: No reason to guess.
UTS of ABS is ~40MPa
UTS of Nylon 12 is ~50MPa
UTS of Stainless is ~850MPa
Consider that layer bonds fail before the material does, so expect a little less from FDM than the above strengths.
You need at least 20 times more material in FDM to get the tensile strength (UTS) of stainless.

Thank you Jersey Girl. What a great and complete answer. I am very early in my research, if you will, so I need to inquire more about FDM printing. I know nothing about dissolvable supports but I'm sure it will become self evident. Thanks for the advice on wasting material.
I do need to ask, if you have the time, about the following statement; "If you make your cross section big enough, you can make any plastic as strong as .03 steel. I personally never use 3D printing for anything beyond prototyping since it does not give me the strength I need as a manufacturing alternative." My finished product would hopeflly only be as thick as 0.03 steel, so how thick might I expect FDM to be in order to acheive that strength? And if you are unsure, do you think it might be twice as thick, 3 times as thick? Just venture a guess if you can.

Taulman bridge is so far the by far toughest stuff i ever printed. It is nearly indistructable. The only disadvantage is it's flexibility compared to ABS, PET, HIPS or PLA.Quote

Taulman nylon is not there yet. I haven't tried Bridge yet so maybe that's an improvement.
