Mechnano and Bomar present new T50B masterbatch

Mechnano, in partnership with Bomar, recently introduced T50B Masterbatch, a specialized low-viscosity product designed specifically to meet the needs of formulators in the additive manufacturing industry. The masterbatch uses Mechnano’s patented D’Func (Discrete, Dispersed, and Functionalized Carbon Nanotubes) technology to develop AM resins with improved mechanical properties and consistent electrical performance at the nanoscale.

“Mechnano Research and Development teams continue to enhance our technologies and expand our product portfolio for the AM industry,” says Mechnano Director of Applications & Technology Dr. Olga “Dr.O” Ivanova. “The initial feedback from beta-customers has been extremely positive, demonstrating enhanced mechanical performance, in addition to ESD capabilities.”

The T50B is a high CNT concentration, low viscosity masterbatch that can be seamlessly incorporated into resin formulations without the need for intensive shear mixing processes. The special blend of Bomar resins used as a dispersion base enables a wide range of resin types and technologies suitable for SLA, DLP or jetting printing processes. The electrical resistivity of the final formulation can be adjusted from 10^5-10^10 Ω, making it an excellent choice for the development of low surface resistivity resins. The integration of T50B into tough and flexible formulas has shown improvements in mechanical performance such as tensile strength and modulus of elasticity.

“This new dispersion is exactly what the industry has been looking for – a versatile, highly concentrated dispersion that enables maximum formulation flexibility and provides excellent ESD properties, all while maintaining printability in UV-based print systems,” says David Robitaille, Global Brand Director for Bomar.

Mechnano’s T50B products integrate its unique D’Func technology, which specifically targets the problem of clumped and entangled carbon nanotubes (CNTs) in materials. The main objective of this technology is to improve both the mechanical and electrical performance of AM resins. By effectively removing these clumps and functionalizing the CNTs, Mechnano ensures the stability of its CNT-based masterbatches. This is particularly important as clumped CNTs have been shown to negatively impact the mechanical properties of materials and lead to inferior overall component performance. Mechnano is constantly expanding its product offering and the T50B is available both directly from Mechnano and through its partner Bomar.

This advancement in additive manufacturing could have a significant impact on the quality and efficiency of 3D printed materials and represents an important step in the development of more advanced and higher performing resin formulations.
