ideaMaker 5.5.3 Release Notes

Oct 21, 2026

FFF Improvements

1. FFF Slice Speed Optimization

  • Optimize algorithm efficiency across all stages of image slicing
  • The standard model optimizes slicing speed, reducing slicing time by 40–50%.
  • For specific types of models, slicing time is reduced by more than 10 times.
  • Tree support algorithm speed optimized by 20–30%

2. Significant optimization of GCode preview loading speed

  • The loading speed of GCode previews has been significantly improved, with at least a two-fold increase.

3. New detour path algorithm

  • Reconstruct the detour path algorithm to prioritize placing detour paths along the inner wall rather than the outer wall.
  • Optimize the performance of the detour path algorithm, reducing the computation time for the detour path itself by 20–30%.

4. Preview external GCODE files to display processing time and material consumption

  • The preview of G-code files on external disks: like internal slicing files, IdeaMaker supports displaying detailed information for each feature.
  • Note: Re-slicing is required before exporting; previously sliced GCODE files do not support this feature.

SLS Improvements

1. Part Box Feature

  • Add a part box feature to the toolbar and menu bar, allowing users to select one or multiple models to generate a part box.

  • The print report will include the results of the part box.

2. Use a standard contour to print the top and bottom surfaces.

  • When this option is enabled, the upper and lower surface contours will be printed using the standard surface contour settings.
    • Enabled

  • Disabled

  • Once enabled, the contour values of the top and bottom surfaces become invalid, but this does not affect the slicing results.

3. Supports basic SLS remote control functionality

  • Supports automatic scanning and manual printer addition.
  • Support for uploading files to the Raise3D RMS220 printer.

4. Preview optimization for external.slscode files

  • When previewing an external SLSCode file, determine the file size; if the file is large or the user’s computer has limited available memory, force single-layer loading and suppress the dialog box prompting the user to make a selection. This prevents low-specification computers from running large SLSCode files, which could otherwise lead to memory exhaustion.

5. The SLS insulation layer is optimized using the V2 algorithm.

  • In the SLS insulation layer V2 algorithm, the option for narrow contour regions will not affect the slicing results.

Other Optimizations

1. Parameter dialog box when importing a STEP file

  • The “Step File Parameters” dialog box will appear when importing a Step file.
  • Parameters can be modified in real time, which affects the number of triangular faces in the imported STEP model.
  • After modification, it will affect the corresponding settings in preferences.

2. After selecting the model, you can freely translate it to expand the scene:

  • Modify and Boolean functions
  • DLP support (not DLP support editing)

3. Others

  • For non-Belt Printers, the slicing template dialog box no longer displays “Repetition GCode” (this setting is also not searchable in the search bar within the dialog box).
  • After importing the project file, no further prompt will be displayed regarding whether to switch printers or materials; if switching is possible, IdeaMaker will automatically perform the switch.
  • The spiral lift follows the tangent direction of the circular arc in the target direction.

Bug Fixed

  • Fixed texture-related functionality; resolved the issue where 3D rendering failed to refresh promptly.
  • Fixedthe Belt Raft issue on the belt printer
  • Fixed the DLP support editing issue.
  • Fixed the SLS packet display issue.
  • Fixed the issue with the support bridging layer.
  • Fixed the travel detour issue.
  • Fix the issue where the inner contour compensation setting within the SLS grouping configuration was not taking effect.
  • Fix some translation issues
