SLS Improvements

1. Optimize the slicing performance

1)Significantly reduced memory usage : The SLS slicing algorithm has been redesigned, resulting in a substantial reduction in peak memory usage.

2)Significantly faster slicing : Overall slicing time reduced to less than 40% of the original .

3)Reuse of identical models : Supports reuse of identical models with different heights, reducing slicing time by about 40% in scenarios with multiple identical models and by about 20% in other scenarios .

2. Optimize the packing performance

1)Multi-model packing acceleration: Significantly speeds up packing for the same model ( 20% speed increase ), and optimizes the speed of different models by about 10% .

2)Reduce memory usage: Optimize the 3D layout algorithm to significantly reduce peak memory usage.

3)Strategy optimization: Significantly reduces the computation time when using the Balanced packing strategy.

3. Optimize the rendering performance

1)Viewpoint clipping rendering: For SLS models, only the model within the field of view is rendered, reducing the screen rendering pressure under large display conditions.

2)OpenGL LOD support : Introduces mesh detail level functionality for SLS models, optimizing hardware and software interaction performance at different viewing angles.

4. Optimize the SLS cost estimation formula

1)The size-compensated model volume is incorporated into the SLS cost estimation formula.

2)After the adjustment, the estimated mass and volume of sintered powder in the same document will be lower than in the old version, and the calculation results will be more in line with reality.

5. Adjust the SLS measurement and detection logic to avoid interference from the amplification factor

1)Measurement tool behavior calibration: The measurement results of the measurement tool are adjusted to the original dimensions of the model before size compensation, and are no longer affected by the magnification factor, ensuring the consistency of the physical reference of the measurement.

2)Printability test data synchronization : The Bounding Box and model volume in the printability test panel are both switched to be calculated based on the values before size compensation.

3)Model Information Panel Update: The amount of model powder in the model information panel has been adjusted to be calculated based on the new part volume and mass formula, providing a more accurate material reference.

6. Optimize the SLS printing time prediction

Based on the printer’s new firmware adjustments, the SLS printing time is recalculated to reduce the discrepancy with the actual printing time.

FFF Improvements

1. Add speed, flow rate, and line width settings for the inner bridge structure

1)It identifies and distinguishes between inner and outer bridge structures, and adds settings for Inner Bridge Flowrate, Inner Bridge Speed, and Inner Bridge Extrusion Width Percentage to achieve fine-grained control over inner and outer bridge structures.

2)The inner bridge structure speed and line width are shown in the following figure:

3)The flow rate of the inner bridge structure, as calculated in the figure below, is 100 * 0.2 * 0.4 * 100% = 8 mm³/s.

4)When the inner bridge structure is output to gcode, the output type is INNER-BRIDGE, but the preview still recognizes it as Bridge.

●The “Detect inner Bridge fills above sparse infill” option has been moved from the “Solid Fill” tab to the” Other” tab.

2. Support thick layer filling with alternating angles

1)For supporting thick-layer structures, a new function “Alternate Dense Support Fill Angle” has been added to improve the support’s resistance to detachment and its stability.

2)When this option is enabled, the filling angles of adjacent thick layers differ by 90 degrees.

3. Supports model groups as a whole in model arrangement and sequential printing functions

1)After grouping the models, use the “arrange models” function to treat the grouped models as a whole.

2)When printing sequentially, models in the same group will be printed together.

4. New infill type: Archimedean Chords

1)Sparse filling increases Archimedean Chords.

2)The solid fill type, Top Surface, Bottom Surface, and First Layer solid fill type now include an Archimedean Chords.

5. Added Infill Anchor feature

1)Increases the length of sparse infill anchor lines; the default value is 0. When the value is greater than 0, anchor line structures will be added to the ends of some fill types.

2)The option type is a percentage of the line width. For example, if the infill line width is 0.4mm and the anchor length factor is 400%, then the anchor length is 1.6mm.

3)The following infill types support the addition of anchor lines:

• Rectilinear
• Gyroid
• Symmetric Wavy Curve
• Wavy Lines
• Cross Hatch
• Archimedean Chords

6. The model before material switching supports spiral lifting

7. Add a new starting point type: Aligned

1)When the start point type is Aligned, the following options are disabled:

• Seam Relative Positives
• Place Seam on
• Allow Placing Seams on Non-Polygon Vertex

2) When the start point type is Aligned, the start point/seam should be aligned as much as possible before considering whether to be close to the fixed layer start point.

8. Extend Shell Infill Order Path Strategy

1)Supports more flexible printing order for inner and outer walls; new options added for Shell and Infill Order:

• Inner/Outer/Inner -> Infill
• Infill -> Inner/Outer/Inner

2) The shell printing order will be modified to: Nth shell -> … -> 3rd shell -> Outer shell -> 2nd shell

3) When shells = 2, the printing order degenerates to Outer Shell -> Second Shell.

9. With Painting enabled, in Fill mode, you can paint only the overhanging areas

10. Support nozzles and Raft/Skirt/Brim nozzles can be set to “Not Specified”

1)No need to modify the support nozzle settings in the template; simply modify the specified nozzles on the model, and all models and supports will use the specified nozzles for printing.

2) In the slicing template, in the following nozzle parameter drop-down list, change “All Extruder” to “Not Specified”:

• Infill Extruder
• Support Extruder
• Dense Support Extruder
• Support Infill Outlines Extruder
• Dense Support Infill Outlines Extruder

3) In the modifier panel, in the Modifier Extruder dropdown list, change “All Extruder” to “Not Specified”:

4) When the Skirt/Brim/Raft nozzle is set to “Not Specified”:

11. Optimize the PA Calibration

1) Complete the missing Bounding Box information for PA Calibration.

2) Added a safety warning when the PA Calibration generation path exceeds the print boundary.

12. Optimize the retraction during wipe

1)The inner triggering conditions for retraction during wipe have been adjusted to prevent the retraction during wipe function from not being triggered in certain scenarios.

2)The spiral lift after wiping is forced to use travel speed instead of the original wipe speed.

13. Optimize the GCode preview

1)Travel path frame splitting: The Travel path was changed from a single frame for the entire path to a single frame per step, enabling segmented animation playback and precise GCode line number positioning.

2)Arc path frame merging: The path generated by the Arc command (G2/G3) corresponds to 1 step for the entire arc (instead of 1 step for each interpolation point).

3)FFF preview adds nozzle 3D model display and velocity display.

• Dynamic position display: Supports real-time rendering of nozzle position in 3D mode (not displayed in 2D mode).
• Status panel linkage: When Steps are adjusted manually or via shortcut keys, the nozzle is triggered to display the Path Type, speed, and volumetric flow rate at the current location.

Function Optimizations

1. Optimize the progress bar

Except for the function to preview gcode/dlpcode/slscode files, the progress bars for all other functions have been changed to be displayed in the top panel .

2. Optimize the mouse wheel zoom

1)Zoom center switching: The default zoom center is changed from “center of view” to “current mouse position” (you can change it back to the default behavior in preferences).

2)Intelligent step control: Optimizes scroll wheel step distance. The farther the view distance, the larger the step per scroll; the closer the distance, the smaller the step, avoiding excessive scaling jumps when the view is close to the model .

Performance Optimization

1. Optimize the rendering performance

1)Real-time cross-sectional rendering: Rendering frame rate increased by approximately 100% , memory usage reduced by approximately 10% , and preparation time for the same model shortened by 40% .

2)OpenGL On-Demand Rendering: Models are rendered only when the interface needs to be updated, significantly reducing GPU load.

Other Optimizations

1)Interference checking speed doubled: The geometric collision algorithm was reconstructed, increasing the overall speed of interference checking to 10 times that of the old version .

2)Multifunctional scene acceleration: Thanks to the breakthrough in interference checking, the time spent importing a large number of models, opening projects, 3D arrangement, and copying/arraying a large number of models has been reduced to less than 40% of the old version.
