The strength of monolithic composites compared to 3D printed composites can vary depending on a number of factors, including the specific materials and manufacturing processes used.

In general, monolithic composites are materials that are made from a single, homogeneous material. These materials can have high strength and stiffness, but they may also have limited design flexibility compared to composites that are made from multiple materials.

3D printed composites, on the other hand, are materials that are made by 3D printing a combination of different materials, such as a matrix material reinforced with fibers or particles. These materials can have complex, customized microstructures that can be tailored to specific properties and applications. The strength and stiffness of 3D printed composites can depend on the specific materials and microstructures used, as well as the quality of the 3D printing process.

It is difficult to make generalizations about the strength of monolithic composites versus 3D printed composites, as the strength of these materials can vary widely depending on the specific materials and manufacturing processes used. It is always a good idea to evaluate the strength and other properties of a specific composite material using appropriate testing methods.

As a rule, the monolithic polymer materials show higher strength in comparison with the same materials the samples of which were 3D printed.

Dear Suganth Velumani

Thanks for the contribution. I'm looking to find a source that makes a comparison between the same materials in different processes.

Dear Serge V. Shil’ko

Thank you. My objective is that the monolithic composites are based on the fact, that interaction and bonding between different materials may show various properties, in this case, lower mechanical properties rather than modern technologies such as additive manufacturing.

Dear Milad Zeynivandnejad,

if so, I can recommend you our paper "Comparative Analysis of Tribological and Mechanical Properties of Extrudable Polymer-Polymer UHMWPE Composites, Fabricated by 3D Printing and Hot-Pressing Methods // Journal of Friction and Wear. – 2020. – Vol. 41, No. 3. – P. 228–235. doi: 10.3103/S1068366620030125

... Three technological methods were used for obtaining of composites in: Multicomponent Antifriction Composite Based on Extrudable Matrix “UHMWPE - HDPE-g-VTMS - PP” for Additive Manufacturing // IOP Conference Series Materials Science and Engineering 795(1):012001

DOI: 10.1088/1757-899X/795/1/012001

Thanks for your contribution Mr. Serge V. Shil’ko

I'll look at the mentioned reference and let you know about the findings.
