Strecs3D

Strecs3D is a pre-processing software that generates optimized infill for 3D printing based on structural analysis results. It automatically configures dense infill for areas under stress and sparse infill for areas without stress, achieving material savings and strength optimization.

• Visualization of structural analysis results. Loads stress distribution from VTK files and displays it in an interactive 3D view. Supports multiple mesh formats and allows full model navigation with integrated camera controls.
• Region segmentation based on stress. Automatically divides 3D models according to predefined stress thresholds. Utilizes mesh processing algorithms to identify structurally critical and non-critical areas.
• Variable density infill generation. Sets infill density parameters proportional to detected stress levels. Implements mathematical mapping between stress values and density percentages.
• Compatibility with slicing software. Exports processed 3MF files compatible with Cura and Bambu Studio. Maintains standard file structure with specific infill modifications.
• Coordinate axes visualization. Displays a three-dimensional reference system with X, Y, Z axis indicators. Facilitates spatial orientation during model inspection.
• Reference grid visualization. Implements a grid display on the base plane for relative measurements. Provides spatial context for dimension evaluation.
• Diagonal camera positioning. Incorporates a camera reset algorithm with a customized diagonal view. Optimizes the initial viewing angle for complete inspection.
• Turntable-style camera control. Allows continuous orbital rotation around the 3D model. Simulates turntable behavior for examination from all angles.
• Reorganized interface with side panel. Distributes UI elements in a dedicated right panel for visualization options. Groups export controls in a centralized location.
• Icon support in Button widgets. Implements a system of file-type specific icons. Uses visual representation to identify functionalities.
• UI components with color management. Applies a consistent color scheme to buttons and controls. Manages visual states for different interaction modes.
• Parameter change monitoring. Detects configuration modifications through an observation system. Updates interface states according to current values.
• 3MF processing for all slicers. Integrates lib3mfprocessor as the standard export backend. Guarantees cross-platform compatibility with different software.
• Corrected ID indexing in Bambu. Solves part numbering issue in the Bambu 3MF processor. Maintains structural integrity of the exported file.
• Centralized axis color management. Unifies color configuration in a specialized ColorManager. Coordinates color palette for display elements.
• Process button state validation. Requires the simultaneous presence of STL and VTK files to enable processing. Prevents execution with incomplete data.

Strecs3D was developed by tomohiron907 as a specialized code project. Development began in 2025 using C++ as the main language with the Qt framework for graphical interface components. The architecture employs design patterns such as adapter for the main window and complete separation between business logic and presentation layer. The software implements VTK processing for 3D visualization and lib3mf for managing 3D printing formats.
