Eh, I think the weakspot in any 3d printing will be the software. As a hobby engineer, I use Solidworks which is several thousand dollars (luckily already on some of my employer's computers so they foot the bill).
But at home, I tried FreeCad, Cubify Invent, and several other free or cheap options and I find them invariably terrible, at least as far my limited experience can discern. FreeCad in particular, asides from UI nonintuitive issues and heaps of bugs (various cuts and operations simply disappearing f
CAD is recognized by the FSF as an area with a lack of suitable Freely-licensed software. It's been on the priority list for awhile now, but I guess not enough companies are funding the projects that are out there.
In the long term I am confident something will come out. As far as I've been able to tell, new versions of AutoCAD just tweak the UI a bit and add 'cloud' intergration or whatever the fad is. The core of the program hasn't changed much.
So, eventually the Free alternatives will be able to catch up.

Really? What is wrong with FreeCAD [freecadweb.org]? It is a full parametric 3D modeling system. It can be scripted in Python. It exports industry standard STL. I find it far easier to use than AutoCAD, SolidWorks, or any other CAD program I have used. I have used it for dozens of projects, and have run into no limitations. I have also used it with a 3D printing class at an elementary school for 4th, 5th, and 6th graders. They also had no problems with it. The license is GPL.
Well... I just got FreeCAD running last night. Been using QCad for several years and recently started OpenSCAD for some 3D modeling. So you want a new FreeCAD user's prospective?
I have spent the last 4 nights, 3-4 hours each night, trying to build and install all the dependancies for FreeCAD v0.14 on a CentOS 6.5 box. It was an absolute nightmare. The build documentation is crap and lists multiple things as requirements that have changed to something else (i.e. PyQt4 -> PySide), dependancies claimed to b
I have spent the last 4 nights, 3-4 hours each night, trying to build and install all the dependancies for FreeCAD v0.14 on a CentOS 6.5 box.
I had no problems at all installing on Ubuntu. At the school we installed onto several old Macbooks, and had no problems there either.
The build documentation is crap
Well, duh. It is open source, so of course the documentation will be crap.
And python? Why would a end-user want to learn Python just to create an object?
You don't have to use Python. It is just an option if you want to write macros or script repetitive tasks. All serious CAD programs have some sort of scripting, and using Python is much better than using some quirky, buggy, customized hack like AutoLISP.
