Slic3r

Due to an ugly bug slipped in the previous release, a quick replacement is out.

This is a very important update, grab it now and enjoy! I want to say thanks to the wonderful community that has been helping with feedback, early testing and nice ideas. A lot of people is involved in our open "quality assurance" process! New ... [More] features: graphical interface for composing multiple objects in one single print (with tools for rotation, scaling etc.) new --merge switch to compose multiple object with auto-positioning from command line new option to randomize starting points across layers automatic detection of additional required perimeters for avoiding haps in domed/sloping objects (the perimeters settings means now minimum perimeters as Slic3r could add more when needed) sequential printing: print a complete object, then move onto next one, with automatic collision detection ability to export STL files of composed plates, as well as a Split command to turn multi-object files into individual objects we can read OBJ files now Improvements: very large memory savings and speed boosts, allowing to process high-resolutions files without getting out of memory; also, the number of threads is customizable very improved surface quality due to new smoothing algorithms the GUI doesn't block while slicing and a Cancel button was added to stop the process hole perimeters are extruded in reverse order (from the outermost to the innermost) to get better overhangs a slight compensation is applied to avoid small hole shrinkage support material now uses honeycomb pattern (much work is still needed on support material) retract before changing tool for dual extrusion Changes: SVG colors were inverted to better support DLP printing (next versions will carry more settings for SVG export) Bugfixes: fixed some GUI memory leaks fixed some fatal errors fixed a bug causing high memory consumption when infilling every 2 or more layers some holes where filled some nearly-thin walls were discarded removed tiny dots/blobs that were generated sometimes bottom layer speed ratio wasn't taken into account when estimating layer time omit any G92 E0 when in relative mode [Less]

Due to an error slipped in the 0.7.2 release and quickly reported by early downloaders, I recommend to download the newly-released 0.7.2b now. Sorry!

We have a shiny new beautiful icon now! Thanks to Corey Daniels for designing it. Major new features: Honeycomb (hexagonal) infill pattern! SVG export for DLP printers and other purposes automatic arrangement for printing multiple ... [More] copies of the same object (thanks Triffid Hunter for contributing this one) New features: new Reslice command in the File menu customizable G-code to be executed at layer change Improvements: huge speed boost (20%-50%) and more parallelization of long-running algorithms new implementation of support material generation don't slow down travel moves when cooling is enabled new --threads command line option to set number of parallel jobs Minor improvements: enable G0 automatically for Mach3 allow decimal values for skirt/duplicate distances and speeds added the coordinates of the first non-manifold edge to the warning messages only output M109 if there's none in the user-supplied start G-code make sure all concentric fill loops are extruded in the same direction to prevent sudden changes of direction Changes: --duplicate-x and --duplicate-y were merged into a single --duplicate-grid option Bugfixes: some holes were filled the No Extrusion mode had no effect use M109 for bed control (Makerbot) use P instead of S for M106 (Mach3) fixed some fatal errors [Less]

New features: new fan always on option bed temperature control (first layer/other layers) Growl notifications Improvements: some algorithms are now less complex (thus faster with larger models) fill/perimeter contact is ... [More] maximized for line pattern slowdown is now triggered regardless of whether a fan is used allow to use config options in start/end G-code, like for output filename pattern throw an error if a user wants to print a 0mm layer remove M82/M83 codes for Makerbot output Changes: the Use relative E option is now back in the GUI remove G0 from the GUI until most firmwares implement it avoid G92 codes for Mach3 output Bugfixes: retraction wasn't triggered when moving between copies a bad "bridge fan end" string was sometimes inserted in G-code fixed some fatal errors fixed some bogus non-manifold errors happening with certain values of first layer height infill extrudates were escaping perimeters sometimes [Less]

This is a very important update: don't miss it and enjoy the goodies! Major new features: a new rock-solid slicing algorithm, based on a topological approach, able to process efficiently a wide range of STL files without any warning ... [More] generation of support material (optionally, with a second extruder) cooling and fan control ability to read the AMF format New features: first layer temperature support for Makerbot and Mach3 G-code flavors duplication is performed on generated toolpaths instead of 3D mesh, resulting in a nearly-constant time for any number of object copies infill and support material are multi-threaded, so they will take advantage of multiple CPUs/cores support for custom post-processing scripts new notes field in configuration profiles Improvements: uses 40% less memory ability to load multiple config files using the command line ask for confirmation when slicing more than one copy contours and holes are extruded in the same direction (ccw) skein multiple files with a single command from command line some compensation for hole shrinkage Minor improvements: do not display the progress dialog as an application-wide modal dialog Config files are now portable between Unix and Windows and allow for Unicode characters added extrusion multiplier to G-code comments Bugfixes: models with rounded walls had small useless infill regions small perimeter speed was applied to all holes too, regardless of their size fixed some fatal errors [Less]

After much work, a new beefy release of Slic3r is ready for download. New features: thin walls! new Output Filename Format option to allow for complex output filenames using option values (like foo_3perimeters_0.15height.gcode) ... [More] automatic retraction at the end of the print Improvements: much better overlap between infill and perimeters in those situations where previous version was still producing gaps smarter order for hole perimeters to save travel and time large internal refactoring (less memory and some speed) bridges now have higher priority than other solid regions loops are now closed better use solid print speed for internal solid layers too checkbox in GUI to enable comments in G-code warn if no layers were detected Changes: Windows package is now distributed as a ZIP file rather than a self-extracting executable Bugfixes: some island having no holes and contained in holes themselves were ignored fatal error in arc detection code wrong month number in output small regions were infilled even with fill_density = 0 fill was escaping perimeters near some corners other fatal errors removed, especially when dealing with dirty files [Less]
