The release focuses on three key areas: greater visibility into preparation steps, automated correction of problematic 3D geometry, and improved tools for reinforcing parts and designing lightweight lattice structures.

A More Transparent Build Preparation Process

One of the most notable additions in 4D Additive 1.8 is its Build History Tree. This feature organizes the operations performed during additive manufacturing preparation into a structured, reviewable sequence.

Rather than treating build preparation as a series of disconnected operations, engineers can inspect the workflow and revisit individual steps. Relevant parameters can be reviewed and adjusted when design requirements change.

This approach can be particularly useful in production environments where part revisions, customer feedback, or manufacturing constraints require repeated adjustments. A more traceable workflow helps teams understand how a build configuration was created and makes it easier to revise earlier decisions without unnecessarily repeating the entire preparation process.

For engineering organizations managing multiple part variants, this type of process visibility can also support more consistent working practices.

Automated Repair for Challenging 3D Models

Preparing imported geometry for 3D printing can be time-consuming when source files contain defects. Triangulated models, including mesh-based formats, may have damaged or inconsistent geometry that needs to be corrected before manufacturing.

Version 1.8 enhances the software’s automatic model-repair capabilities with an Advanced Automatic Mode. The feature combines a sequence of repair operations to address multiple geometry issues with less manual intervention.

The software supports workflows involving both precise CAD geometry and triangulated models. Engineers can selectively convert CAD geometry into a triangulated representation and apply mesh-repair tools where appropriate.

This flexibility is important when working with models from different design applications, external suppliers, scanning workflows, or legacy datasets. Reducing the amount of manual cleanup can help shorten preparation cycles and allow engineers to focus more attention on manufacturability and part performance.

Automated repair does not eliminate the need for validation, however. Critical components should still be checked to confirm that the repaired geometry meets the intended design and manufacturing requirements.

Reinforcement Structures for Thin-Walled Components

Thin-walled and large-surface components can be difficult to manufacture using additive processes. Depending on the material and process conditions, thermal effects and internal stresses may cause unwanted deformation.

To address this challenge, 4D Additive 1.8 introduces a stiffener function that supports the creation of reinforcement structures during build preparation. These structures are intended to improve the stability of susceptible geometries and help reduce the risk of warping during manufacturing.

This capability may be particularly relevant to industrial parts where maintaining dimensional accuracy is essential. Potential applications include lightweight housings, panels, and other components with broad surfaces or relatively thin walls.

The practical outcome will depend on the geometry, material, printing technology, and selected process parameters. Engineers should therefore evaluate reinforcement strategies against the requirements of each build.

Lattice Structures for Lightweight Design

Lattice structures are increasingly important in additive manufacturing because they can provide tailored mechanical characteristics while reducing the amount of material used in selected regions.

The latest 4D Additive release expands the options for adapting lattice designs to component geometry and functional requirements. This gives engineers additional flexibility when developing lightweight structures or optimizing the internal architecture of a part.

Depending on the application, lattice-based design can support goals such as mass reduction, material efficiency, and functional integration. However, achieving these benefits requires careful consideration of loading conditions, manufacturing limitations, and inspection requirements.

Combining lattice design with other build-preparation tools can help teams assess how a component’s geometry should be adapted for the intended production process.

Why These Updates Matter for Engineering Teams

The improvements in 4D Additive 1.8 address several practical challenges in additive manufacturing workflows:

• Workflow traceability: A structured build history makes preparation operations easier to inspect and revise.
• Less manual geometry repair: Automated healing tools can reduce the effort required to prepare imperfect mesh data.
• Improved manufacturing stability: Reinforcement structures provide another option for addressing deformation risks in thin-walled parts.
• More design flexibility: Adaptable lattice structures support lightweighting and application-specific geometry.
• Potentially shorter preparation cycles: Combining these capabilities may help reduce repetitive work when models or production requirements change.

The overall value depends on how well the software fits an organization’s existing CAD, engineering, and manufacturing processes. Teams should assess data compatibility, validation procedures, and production requirements before introducing new tools into established workflows.

The Bigger Picture: Preparing Better Data for Additive Manufacturing

As industrial 3D printing moves into increasingly demanding applications, the quality of digital preparation becomes a key part of manufacturing success. Reliable geometry, traceable operations, and suitable structural design all contribute to a more predictable workflow.

CoreTechnologie’s 4D_Additive 1.8 reflects this direction by bringing process-history visibility, automated model repair, reinforcement functions, and lattice design improvements into the same software environment.

For manufacturers working with complex or frequently revised parts, these capabilities offer additional ways to streamline preparation and address geometry-related challenges before production begins.
