Slic3r

0.5.3 is out!

Bugfixes:

• options having zero values were broken 0.5.2
• hollow objects were printed with wrong sparse infill
• minor errors

0.5.2 is out!

A new release just after two days!

New features:

• new Extrusion width ratio option to force a given ratio between extrusion width and layer height instead of having Slic3r calculate it automatically
• new super-fast concentric infill pattern

Improvements:

• GUI progress bar is not determinate and shows some information
• avoid unnecessary retractions during infill

Changes:

• Filament packing density was renamed to Extrusion multiplier

Bugfixes:

• Infill every 'n' layers was broken after recent changes
• setting Temperature to zero didn't remove it from output

0.5.1 is out!

10 more days and a new release is there!

New features:

• if Temperature is set to zero, no temperature control will be added to the resulting gcode file

Improvements:

• large refactoring of the bridging logic - all bridges should now be detected (although some work needs to be done on optimal infill direction); the quality of solid surfaces and regions near bridges and solid surfaces has improved a lot
• use solid infill under pillars and small regions instead of using an internal low-density infill
• don't die on non-manifold models; always try to generate some output

Changes:

• print settings moved to first tab
• M109 is used instead of M104 for temperature control

Bugfixes:

• bottom layer speed was ignored
• some solid layers were skipped
• some ghost lines were extruded in open air outside the object when a 45° infill angle was used

0.5.0 is out!

After 10 more days of work, a new release is out!

New features:

• four new exciting fill patterns (including line)!
• new algorithm for re-processing layers with dirty geometry, this makes the parser more tolerant
• start and end gcode is customizable in the GUI too
• new --retract-lift option to lift Z while doing travel moves
• new --no-extrusion option to disable E codes
• new --skirt-height option
• new --first-layer-height-ratio option
• new --close-after-slicing for easy integration with external programs
• new --g0 option to output G0 for fast retractions (experimental)

Improvements:

• perimeters are extruded at once for each island, saving on travel toolpaths
• perimeters are extruded using a shortest path search, avoiding unnecessary travel
• smarter toolpaths for infills with different density
• multiply was renamed to duplicate
• infill is now overlapped with perimeters by 15%
• GUI was rearranged using tabs

Bugfixes:

• fixed fatal error occuring on Windows
• infill solid layers even when --fill-density is set to zero
• membranes were not printed correctly
• G2/G3 coordinates for experimental arcs were wrong
• print first layer at Z = 1 * layer height instead of zero

The birth of a Slic3r community

Here we are. After two months since I started to write this software from scratch, there are many people enjoying using it. And I'm enjoying to receive their feedback!

Tech Paladin published a post entitled Slic3r 0wns with some pictures:

Joachim Glauche, owner of RepRapSource.com and creator of the ShaperCube published some pictures of nice high-resolution prints sliced thanks to the speed and accuracy of Slic3r.

Some people printed the same object with Slic3r and Skeinforge and published pictures with the comparison: see this picture by Blue_Metal, this one by John Ridley. Also, see this picture by Richard Goodwin.

There are also a couple YouTube videos: this and that.
