# Inkbit launches Cyclic Olefin Thermosets (COT) for mmWave Applications

[Inkbit](https://www.voxelmatters.directory/company/inkbit/) has officially introduced Cyclic Olefin Thermosets (COT) to its Vision-Controlled Jetting (VCJ) platform, marking a significant advancement for engineers working in the mmWave space. Combined with VCJ's AI-driven multi-density material jetting capabilities, this latest material launch represents a paradigm shift in how dielectric components are conceived, iterated, and produced. COTs are engineered for performance, offering exceptional dielectric stability, thermal resilience, and compatibility with high-frequency applications ranging from 3 GHz up to 90 GHz. This makes them ideal for complex mmWave designs such as conformal antennas, waveguides, beam-shaping devices, and gradient-index (GRIN) lenses.

When combined with VCJ, a closed-loop additive manufacturing technology that leverages real-time machine vision, engineers gain unprecedented control over component geometries and dielectric properties. This unique pairing allows for the fabrication of multi-material parts with intricate internal features and smooth dielectric gradients, making previously impossible designs now manufacturable.

Davide Marini, CEO of Inkbit, emphasized the significance of this development for RF engineers: "The synergy between COT materials and Inkbit’s production platform dramatically increases the speed at which engineers can design, test, and deploy advanced components—ultimately helping them move from concept to deployment faster than ever before. This flexibility is essential in fields like telecommunications, aerospace, and defense, where time-to-market and high-performance standards are non-negotiable," he stated.

## mmWave applications and signal integrity

The ability to control dielectric properties across complex geometries unlocks new possibilities for electromagnetic applications. Engineers working with GRIN lenses can now achieve continuous refractive index profiles across the lens surface, significantly improving beam shaping and focusing capabilities. Inkbit’s COT-enabled components also meet the stringent requirements of radomes and enclosures, offering both a lightweight structure and environmental stability without compromising RF performance.

This allows for creating dielectric waveguides, metasurfaces, and conformal antennas tailored for custom applications. Engineers are no longer confined to off-the-shelf designs or legacy manufacturing methods. With Inkbit, designs that previously required complex tooling or manual assembly can now be digitally fabricated with high repeatability.

At the International Microwave Symposium (IMS) in San Francisco, Inkbit showcased demo parts and shared real-world application examples. Attendees had the opportunity to explore how this technology fits into modern RF workflows and discover how they can incorporate COT-based solutions into their own product designs. From rapid prototyping to scalable production, Inkbit's platform ensures that design complexity no longer limits innovation.

## Inking the future of RF engineering

Inkbit’s additive manufacturing solution is uniquely positioned to meet the growing needs of industries pushing the limits of mmWave technologies. Engineers working on cutting-edge solutions—whether for 6G communications, advanced radar systems, or custom wave-routing structures—now have access to a platform that supports rapid design cycles and performance-centric component fabrication. The combination of Vision-Controlled Jetting and Cyclic Olefin Thermosets delivers continuous dielectric gradients, high thermal stability, and excellent performance across broadband frequencies.

What sets Inkbit apart is its commitment to empowering engineers with tools that do not compromise between precision, scalability, and innovation. The company's technology is proving transformative across a wide range of high-performance applications, from conformal antennas integrated directly into aerospace surfaces to compact switch-beam lens arrays used in automotive radar systems. Engineers can design freely without sacrificing dielectric accuracy or manufacturability.

The ability to fine-tune dielectric properties, integrate custom geometries, and scale from one prototype to thousands of units with end-use consistency places Inkbit at the forefront of RF manufacturing innovation and could prove to be one more killer application in the company's arsenal.
