You need:
Digital Designer (Or anything that can produce Ldraw files, there are some listed in this question)
Blender (Or another renderer that supports Ldraw)
Blender Script (This is necessary for Blender to read you Ldraw models)
Recreate your creation in Lego Digital Designer.
Export as Ldraw format
Import in Blender
Create & render Blender scene
...

In addition to the other answers, the oldschool way using POV (in use before there even WAS a LEGO Digital Designer) still works.
Model your creation in a LDraw compatible modelling tool of your choice (such as MLCad) but there are other choices
Use one of several export programs (such as L3P) to create a POVRay compatible file
Add a few commands to move ...

To build your example in MLCad (LDraw), I needed to switch to "Grid Fine" to move the element into the right alignment:
A couple of techniques to note when doing this when you finish with the SNOT modeling:
Set the grid back to coarse so that subsequent pieces are back on the grid.
Select a non-SNOT element (in this case the 2x3 or 2x2 plate) before ...

First note that this question is a possible duplicate of Do any programs exist that allow you to build your own LEGO manuals? With that, here is the answer:
(optional) Create a model in LEGO digital designer or LDraw and export it as a LDraw (*.ldr) file.
Install LeoCAD, and either open the model that you made in LDD/LDraw (recommended) or create your ...

Almost certainly no, but with some caveats:
The LeoCAD parts library is based on the LDraw parts library, which has a Legal Agreement here.
The vast majority (and I would assume the entire subset used by LeoCAD) are covered under the Creative Commons Attribution License 2.0:

Depends on your tolerance. :)
http://en.wikipedia.org/wiki/Lego says: "The machines that make Lego bricks have tolerances as small as 10 micrometres."
For me, 3D printing resolution would need to be pretty close to that.

The LXFML file is an XML document, and there's an XSD document that you can use to validate any LXFML file, along with a textual description of the tags on the LUGNet forums supplied by the LDD Team a few years ago:
LXF files - info and XML schema
The key parts of the LXFML you're going to be interested in start with the <Scene> element, which ...

You can't directly export from MLCad to the .STL format that the Makerbots require, but there are workflows you could probably set up.
MLCad doesn't really have many export options, so you're better off using something like LeoCAD which can read .ldr files from MLCad, and export as other formats.
Using LeoCAD, add the part you want to print to the scene.

Both, often in the same file.
If you take a look at the .ldr file format specification you can see that each file is made up of an number of different types of "line", one of which is a Subfile Reference where you can specify the colour, position, rotation and scale of the model.
Other lines can then be added to describe Lines, Triangles, Quadrilaterals ...

Let me suggest Autodesk 3ds Max software or Autodesk Maya software for achieving this. You can find free bricks and models meshes right here. Additional information on lego visualization can be found on Okino's website.
Here is the example of a rendered still. Doing a manual simply involve making parts of the model visible/invisible and positioning the ...

Here's a method you'll be able to use with the latest stable version of Blender, without any extra plugins or addons.
Build your model in LEGO Digital Designer and export as an LDraw file.
Import into LeoCAD, then export as a .obj file.
Import into Blender with the built-in .obj importer.
You can then setup the scene how you want.
Also, if you're just ...
