Dyndrite End-User Software Expands Development for LPBF Machines

Dyndrite has developed the company’s first end-user application focused on materials and process development for laser powder bed fusion (LPBF) machines. The software is said to give LPBF materials, part/process and applications engineers power and control over their geometry, build specific toolpathing and laser parameters, all while enabling the use of new alloys, build rate strategies and methods for printing previously unprintable parts. The software also provides native file support for a variety of LPBF machines, including Aconity, EOS, Renishaw, SLM Solutions, Trumpf and others.

“The industry previously did not have the software needed to rationally explore the opportunities provided by laser powder bed fusion processes. Users could not efficiently investigate new materials, new build strategies or even new machine architectures,” says says Steve Walton, Dyndrite head of product. “Dyndrite changes this. This new software provides a flexible new approach, a new data model, innovative and performant APIs, and complete access to toolpath geometry for those who want or need to go further.”

Dyndrite Materials and Process Development for LPBF application was designed for the needs of materials and process innovators pushing the boundaries of laser metal-based AM manufacturing. It is said to take maximum advantage of the features within the company’s Accelerated Computation Engine (ACE), including working directly with native CAD data, handling massive files, the ability to create shareable build recipes and improving print quality for various geometric features such as domes, cantilevers and thin walls. 

The LPBF software takes advantage of the company’s previously announced 3D Volumetric Part Segmentation technology, which enables the detection of upskins, downskins, inskins and part features typically missed by 2.5D layer-by-layer-based solutions. Using this new geometry query method, parts, materials and machines can now be quickly qualified using geometric operations to compensate for challenges associated with process physics, the company says. Moreover, 3D volumetric segmentation means users never need to manually combine multiple build files again.

Dyndrite’s ability to save out “build recipes”' opens the door to transparent and shareable toolpathing recipes that unlock the full potential of what’s possible on LPBF machines. The company says anyone can now make a recipe and share it. 

Working with CAD data directly enables seamless and automated CAD-to-print strategies that shorten print preparation, enable flexible part support strategies and speed DOE experiments.

“Dyndrite’s Toolpathing API unlocked a new dimension of flexibility for our additive manufacturing processes,” says Sam Miller, director, AM Software, AM automotive manufacturer. “The additional control over our SLM machines enables us to achieve better material performance and cost productivity in a high-quality manufacturing environment."

The Dyndrite Materials and Process Development for LPBF application is available via the company’s “Early Adopter Program” — a white-glove service offered to a limited number of customers. The LPBF software provides off-the-shelf support for leading LPBF machines, including Aconity3D, AddUp, EOS, Farsoon, Renishaw, SLM Solutions, Trumpf and others.
