How do you actually 3D print an object?

3D printers vary, but the typical
3D workflow is as follows:
1. Create a 3D model in a special 3D design
program, such as SketchUp, Blender, Autodesk 123D, Rhinoceros, SolidWorks, etc,
and export it in STL format (STL is the acronym for Standard Tessellation
Language – it's the software file format used to produce 3D models on 3D
printers) to your 3D printer's Host software. Alternatively, if you don't have
design skills, download any pre-designed STL model that takes your fancy from
an Internet shop – many designers make their designs available for free.
2. In your 3D printer's Host software, arrange one
or more STL models on a virtual print plate on your computer screen (to fit the
size of your printer’s plate).
3. Slice the model(s) into thin slices and compute
a path for the printer head to follow. This is done by slicing software, which
automatically converts a model into G-Code – the language your 3D printer
speaks. Some Host software, such as Repetier-Host, has built-in Slic3r software.
4. Check the G-Code for errors and printability
(this is automatic in programs such as Repetier).
5. Send the G-Code to your 3D printer.
6. Monitor your printer as it prints.
7. Carefully remove your completed 3D printed
models from your printer.
8. Some models may need some post-processing to
achieve the desired result. This includes removing support struts, infills or
unwanted blobs; filing and sanding rough edges; treating the model with
chemicals or gluing individual model parts together; painting, varnishing or
adding special finishes.
