Optimizing Composite Materials Through 3D Printing: A Significant Advance for Additive Manufacturing in Benin

Mohamed Daly, a researcher at the National Polytechnic Institute of Brittany, has resolved technological bottlenecks concerning the mechanical performance of 3D-printed composite materials. His thesis, defended in 2025, demonstrates that optimizing infill configurations can reduce warping defects, paving the way for applications in demanding sectors such as aerospace and automotive.

3D printing is transforming key sectors, yet it faces challenges such as part warping and production rates lower than those of traditional methods. Mohamed Daly's thesis focuses on optimizing the mechanical performance of thermoplastic materials, particularly those reinforced with carbon fiber. This research aims to improve the structural integrity of finished products.

Using numerical modeling techniques and dynamic testing, Daly demonstrated that the choice of reinforcement type and infill configuration significantly impacts mechanical properties. For instance, optimized configurations can reduce warping and residual stress, thereby improving the strength and durability of printed materials.

The findings of this research carry strategic implications for decision-makers, offering opportunities for innovation across various sectors. By optimizing composite materials, companies can reduce production costs and improve product performance, which is crucial to remaining competitive in the fast-growing composite materials market.
