Slic3r 1.0.0RC1 is out!

A huge amount of work went into this release candidate build. Try it yourself and please report any issues so that we can release a bug-free stable 1.0.0 version soon!

(I would like to thank, among others, @stepanb and Microsoft Czech for their support.)

Major new features:

  • built-in automatic STL repair
  • OpenGL 3D preview of the repaired file (thanks to iXce for the initial work); also supports multi-material files
  • ability to override individual config options for each object in the same print job
  • new support material rewritten from scratch
  • new Ooze Prevention feature for multiple extruders (park extruders outside skirt and drop temperature by a specified delta)
  • options to avoid starting loops on convex vertices and/or overhangs
  • volume calculation
  • ability to customize how materials are mapped to extruders
  • new First Layer Acceleration option
  • new option to use firmware-controlled retraction (G10/G11)
  • new option to use a distinct extruder for support material interface

Improvements:

  • Slic3r is now much faster because many mature parts of code were rewritten in C++ for faster processing and less memory usage (Slic3r is now 40% C++)
  • most of memory is now truly shared between threads, reducing the total footprint
  • improved infill patterns and bridge detection
  • the automated test suite was largely enriched
  • don’t combine retract and travel anymore when using G0 (Mach3 compatibility)
  • better Makerbot (Makerware/Sailfish) compatibility
  • Windows binaries are now built with Expat for faster AMF parsing

Minor improvements:

  • new [layer_num] placeholder in layer-change G-code
  • custom G-code can be supplied via command line too
  • some options were renamed or rearranged for clarity
  • new –info command line option to get information about the file
  • add .ngc to supported G-code suffixes
  • the wizard now saves initial profiles automatically
  • automatically copy Simple Mode settings into a ‘Simple Mode’ preset in Expert Mode

Changes:

  • layer height ranges are scaled automatically when object is scaled in plater
  • avoid G92 E0 for sailfish output
  • the “Infill every n layers” option was renamed to “Combine infill every n layers” to clarify its purpose

Bugfixes:

  • several threading issues were fixed
  • some situations causing incomplete infill were fixed
  • fixed regression causing wrong direction for inwards move in holes, thus little blobs
  • fix crash on Windows when username had non-ASCII characters
  • some spiral vase prints had little gaps in the loops
  • Z-offset was not applied to spiral vase prints
  • lift was not working correctly with multiple extruders and multiple skirt layers
  • fix speed math for wipe, which was causing too fast retraction
  • other minor fixes
