At the 2026 Beijing International Commercial Aerospace Exhibition held recently, the most eye-catching displays were undoubtedly advanced rocket engines and components. However, ManGe Technology’s 3D printing data solutions stood out for their distinctive approach and attracted significant attention.
As commercial aerospace companies increasingly adopt 3D printing technologies, more advanced design requirements, structural simulation, process simulation, and massive data volumes have emerged as new challenges. ManGe Technology provides domestically developed core tools aimed at addressing these issues, helping commercial aerospace users tackle design, simulation, and data management challenges associated with large-scale, complex, and integrated structural manufacturing.
Structural Lightweight Design
ManGe Technology has independently developed VoxelDance Design (VDD), an implicit modeling tool capable of performing topology optimization and lattice structure infill for structural components. To demonstrate this capability, ManGe showcased four case studies at the exhibition, all designed using the software and manufactured via 3D printing.
The first example is a lightweight valve body developed with weight reduction as its primary objective. The overall design integrates topology optimization and lattice infill strategies. The upper section adopts a conventional lattice structure, while the lower section utilizes a TPMS (Triply Periodic Minimal Surface) lattice. This approach enables significant weight reduction while maintaining structural strength. In addition, external reinforcing ribs were incorporated to enhance structural integrity and prevent deformation of thin-walled sections during the printing process.
The second example is a lightweight pedal structure featuring three different lightweight design schemes, primarily intended to demonstrate the diverse optimization pathways enabled by the VDD software.
All design options are based on load analysis of the component. The lattice infill can be implemented with variable strut diameters, variable unit cell sizes, or through a hybrid approach that combines topology optimization with lattice structures to achieve ultra-lightweight structural design.

All of these optimized structures were designed using VoxelDance Design (VDD), enabling engineers to perform highly efficient lattice infill within a unified workflow.
Extreme Data Compression for Greater Efficiency
One of the major challenges in current metal 3D printing applications is the massive volume of data. Not only do large components consume enormous memory, but even small parts can generate huge datasets due to extensive lattice infill and the resulting proliferation of triangular mesh facets. ManGe Technology pointed out that some 3D-printed parts today can reach file sizes of up to 18 GB. Most commercially available software struggles to parse such large datasets, let alone perform slicing and laser path generation efficiently.
ManGe’s latest solution addresses this issue smoothly. The company explains that traditional modeling methods rely on triangular meshes to represent geometric details, which is the fundamental cause of oversized files. In contrast, VDD adopts an implicit modeling approach. Instead of storing explicit mesh data, it uses algorithm-driven script blocks to define geometry, enabling data volumes to be reduced by up to three orders of magnitude.
This extreme reduction in data volume significantly accelerates design iteration and data transfer, reduces the risk of errors, and delivers tangible efficiency gains across the workflow.
Deformation Simulation: Enabling First-Time-Right Printing
ManGe Technology’s software suite not only supports 3D printing process simulation, but also integrates design simulation and reverse compensation functions. These capabilities help ensure that designs can be successfully manufactured while maintaining dimensional accuracy.
TPMS structures are increasingly used in heat exchanger manufacturing. Users can conveniently incorporate such structures using VoxelDance Design, and ManGe emphasizes that the software ensures smooth transitions between the outer walls of a part and the internal TPMS structures, preventing the formation of sharp debris. Such fragments could negatively affect cooling performance and potentially cause issues during printing.
At the exhibition, the company showcased a spiral heat exchanger as a case study, noting that potential printing issues were predicted in advance using VoxelDance Engineering. This simulation-driven approach helped ensure a successful print outcome.
Another key function is reverse compensation, which enables either global or localized compensation adjustments. In 2025, ManGe further upgraded this capability by introducing a new “scan-based deformation compensation” technology, enhancing accuracy by incorporating scanned distortion data into the compensation process.

Reverse Compensation for Curved Thin Walls: Accuracy Improved by 66.2%
In metal 3D printing applications, users often assume that running a single simulation before printing is sufficient to ensure manufacturing success. In reality, this is not always the case. When dealing with complex components, one round of simulation and reverse compensation may not effectively resolve deformation issues.
A closed-loop solution—“design → print → scan → compensate → reprint → validate”—is often required to fully address dimensional deviations. To demonstrate this capability, ManGe showcased an aero-engine tail-section component at the aerospace exhibition. Based on process simulation results, deformation compensation was applied before reprinting, ensuring dimensional accuracy and eliminating distortion in the final build.
