Covestro, ParaMatters Jointly Develop Anisotropic Optimization Software

Covestro and ParaMatters have jointly developed optimization software for anisotropic materials. By combining ParaMatters’ expertise in design and manufacturing optimization technology with Covestro’s knowledge in engineered materials, the two companies have set out to deliver a complete anisotropic design and workflow that unlocks the full potential of filament extrusion 3D printing with fiber-reinforced materials.

The companies say that designers and engineers can use the new optimization tool to quickly obtain the most optimal part design based on material deposition and fiber orientation, and generate the most efficient printer toolpath. The result is materials, weight and cost savings — while maintaining part performance — that is said to surpass what can be achieved today by engineers relying on experience or intuition.

Additively manufactured parts produced from fiber-reinforced materials are said to provide a valid alternative to metal parts due to a better strength-to-weight ratio, thereby reducing part costs and supply chain complexities. However, until now none of the existing topology optimization tools were able to consider these anisotropic materials, the companies say.

Following a successful initial evaluation by leading aerospace users — including the Composite Technology Center (CTC) — on multiple filament extrusion printers, Covestro and ParaMatters are introducing a beta version so more users can exploit the full benefits of anisotropic materials.

The CTC was one of the first companies to fully evaluate and validate the value of ParaMatters anisotropic generative design and manufacturing engine. “ParaMatters’ anisotropic optimization capabilities allow us to combine multiple stages into a single step, enabling us to cut development times by orders of magnitude, and create stronger and more light-weighted components,” says Marc Fette, CTC CEO.

The collaboration between software, materials and equipment players takes manufacturing, material science and generative design to the next level, the companies say. “We can now realize large savings in materials, printing time and cost while maintaining performance and quality,” says Hugo da Silva, head of additive manufacturing at Covestro. “Definitely a promising route toward scalable and more sustainable 3D printing.”
