What is Slic3r?
Compatible with your printer too. RepRap (Prusa Mendel, MendelMax, Huxley, Tantillus..), Ultimaker, Makerbot, Lulzbot AO-100, TAZ, MakerGear M2, Rostock, Mach3, Bukobot and lots more. And even DLP printers.
Fast G-code generation is fast. Don't wait hours for slicing that detailed model. Slic3r is about 100x faster than Skeinforge. It also uses multithreading for parallel computation.
Lots of input/output formats. Slic3r reads STL, AMF and OBJ files while it can output G-code and SVG files.
Do you like the graphical interface or command line? All the features of the user-friendly interface are also available from command line. This allows to integrate Slic3r in your custom toolchain and batch operations as you like.
Open source, open development. Slic3r is open source software, licenced under the AGPLv3 license. The development is centered on GitHub and the #slic3r IRC channel on FreeNode, where the community is highly involved in testing and providing ideas and feedback.
Dependencies? Nah. Slic3r is super-easy to run: download, double click and enjoy. No dependencies needed. Hassle-free. For MacOS X, Windows, Linux.
Print with dual multiple extruders. Print beautiful colored objects, or use your secondary extruder to build support material. Or put a larger nozzle on it and print a faster infill.
Use brim for the best adhesion. This unique feature improves built plate adhesion by generating a base flange around your objects that you can easily remove after printing.
Microlayering: save time, increase accuracy. You can choose to print a thicker infill to benefit from low layer heights on perimeters and still keep your print time within a reasonable amount.
Compose a plate but print one object at time. Use the built-in plating interface that allows to place objects with drag-and-drop, rotate and scale them, arrange everything as you like. The sequential printing feature allows to print one complete object at time in a single print job.
Cool cooling strategies. A very smart cooling logic will regulate your fan speed and print speed to ensure each layer has enough time to cool down before next one is laid on it.
Manage multiple printers, filaments and build styles. The configuration handling system was designed for people working with multiple machines and filaments: you can save configurations as presets for each category avoiding to multiply your saved configurations.
Enjoy support material. Automatic generation of support material for overhangs.

What is an STL file?
Design format used for stereolithography, a rapid prototyping technology used for producing three-dimensional parts; contains a 3D design used as a master model for creating numerous prototypes.
Stereolithography is an interchange file format. It is used to save CAD files in a standard format that can be read by multiple CAD applications.

Game file used by SuperTux, a 2D jump and run side scrolling game similar to Super Mario Bros.; saved in a plain text format and specifies the features of a level, such as enemy unit locations, positions of blocks, and the time limit; also includes a reference to the music and background image for the level.
STL files are stored in the /data/levels/ directory of the installation.

Library of styles referenced by Macromedia (now Adobe) Fireworks; may be used to apply Stroke, Fill, Effect, and Text attributes to an object within an open Fireworks project; can be helpful for creating a uniform look across multiple objects.
Some styles are included with Fireworks, though additional styles may be added to the program. To add extra styles, click the small icon in the top right corner of the Styles panel in Fireworks and select 'Import Styles.' Then browse to an STL file and click OK to add the style library to your current collection.

.STL File Association 5
Movie subtitles file used by video playback and authoring applications; stores the time each subtitle should be displayed; also specifies instructions for how to display subtitles; used for broadcasts, annotating video files, or for storing movie translations.
STL files contain commands, comments, and entries. Commands begin with the dollar sign ($) character and can specify fonts, colors, alignment, and other subtitle properties. Comments are delimited by '//' characters. Entries contain the actual subtitle timestamp and text. Here is an example entry:
Thousands of graphic, graph and data attributes, including artwork, maps, autoscaling and many effects can be set by applying a skin made with Vvidget Builder (an optional Mac OS X desktop. Best graphing software mac free software.
00:00:11:13 , 00:00:11:42 , This is an example subtitle.
NOTE: STL subtitles are sometimes referred to as EBU subtitles, since the standard comes from the European Broadcasting Union (EBU).
