Release Notes – Changelog of Simplify3D (S3D) v4.1

Version 4.1.0

  • Prime Pillar and Ooze Shield have been upgraded to fully support up to 6 separate extruders
  • New Prime Pillar and Ooze Shield construction provides better stability, improved bonding between layers, and reduced material contamination
  • Improved priming sequences ensure that a tool is always primed at the beginning of each layer during multi-extrusion prints
  • Print time estimates have been greatly improved by simulating the actual behavior of the printer firmware for increased accuracy
  • New intelligent bridging algorithms utilize the model topology to automatically select the best bridging toolpaths
  • Bridging toolpaths will now be added, even when using concentric external fill patterns
  • Improved bridging behavior when dealing with multiple overlapping models
  • Sequential printing can now be used with multi-extrusion prints, allowing you to print multiple dual extrusion groups on a single build platform with reduced stringing between parts
  • When printing multiple parts, the raft for each model is now printed sequentially with its corresponding part for improved adhesion
  • Improved ability to use define separate Additions settings (rafts, skirts, etc) for nearby parts on the print bed
  • Solid layer regions have been optimized so that they are only added when absolutely needed
  • New solid layer toolpaths improve bonding between perimeters on the layers above and below, creating stronger parts in the Z-direction
  • Movement sequences have been further improved to avoid knocking over small parts when changing layers
  • Faster preheat times for multi-extruder builds
  • Fan and temperature per-layer setpoints now work more intuitively in conjunction with the Variable Settings Wizard
  • The layer number that is displayed during Preview Mode has been updated so that it is more intuitive for multi-process prints
  • Feature type comments in the G-Code file have been updated with a new prefix for easier searching and parsing
  • Using a first layer height below 100% will now correctly reduce the amount of extruded material (alternatively, a negative global Z-axis offset can be used to lower the first layer while still extruding the same amount of material)
  • Drag-and-drop can now be used to load a new G-Code toolpath preview while already in Preview Mode
  • Improved interface usability for machines with extremely large build volumes
  • Added support for a wider range of OBJ files
  • Improved slicing for degenerate models, allowing these common mesh issues to be automatically healed by the software
  • Numerous improvements for processing extremely large or complex build files
  • The custom post-processing scripting engine available in the software has been optimized for faster execution times
  • BFB toolpath formats have been significantly improved for quicker exporting
  • Numerous performance and memory usage improvements
  • New Portuguese language translation available by going to Help > Change Language
  • Improved translation consistency for French, German, Italian, Japanese, and Spanish translations
  • Software installers now include complete language translations, allowing you to select your preferred language during setup for improved accessibility
  • Mac installer has been updated to be full 64-bit to avoid any potential warnings during installation
  • Fixed a bug that was causing slow wipe speeds in certain situations
  • Skirt and ooze shield toolpaths have been improved to remove extremely short movements
  • Resolved an issue that had impacted FFF settings import from previously exported G-Code files
  • Over 100 additional bug fixes across many different parts of the application for issues identified by our community
  • Added support for over 50 new 3D printers including the Alfawise U20, Anycubic Chiron, Creality Ender 3 Pro, Creality CR-X, FlashForge Adventurer 3, FlashForge Guider II, FlashForge Inventor II, Geeetech A10, Geeetech A30, PowerSpec Ultra 2.0, Qidi Technology X-pro, TEVO Flash, Ultimaker S5, and many more

Version 4.0.1

  • Improvements for the Variable Settings Wizard to support a wider variety of machines and setups
  • Extended compatibility for Windows rendering environments with reduced graphics support
  • Process ordering improvements for sequential printing control
  • Improved reliability for transitions between multiple processes
  • Better handling for prints with zero perimeter outlines
  • Improved naming prompts when using the “Save As New” option to create a new profile
  • USB communication settings are now maintained after a printer is connected, making it easier to setup builds for new machines
  • Updated support for the latest MakerBot and Dremel firmwares
  • Solved several rare situations that would cause slicing to take longer than intended
  • Resolved an issue with prime pillar and ooze shield toolhead sequences
  • Resolved an issue with large file handling on some Windows systems that had affected toolpath and factory file operations
  • Other miscellaneous stability and performance improvements
