Inkbit's 3D Printed Lenses Revolutionize mmWave in ASEAN

A New Era for mmWave Technology in ASEAN Factories \\[Inkbit, a Massachusetts-based 3D printer manufacturer, has recently unveiled a groundbreaking innovation: 3D-printed gradient-index (GRIN) lenses designed for radio frequency (RF) and millimeter-wave (mmWave) systems. This development, in collaboration with the University of Delaware, was showcased at the IEEE International Microwave Theory and Technology Symposium (IMS) in 2026. The implications for Southeast Asian factories, particularly in Thailand, Vietnam, Indonesia, and Malaysia, are significant. These lenses, which can now be printed as a single graded structure, offer a more efficient and cost-effective solution compared to traditional methods. \\[Traditional manufacturing of GRIN lenses, such as the Luneburg lens, involved stacking multiple dielectric parts, leading to signal losses and limited scalability. Inkbit's Vision-Controlled Jetting (VCJ) platform, combined with a specially engineered Cyclic Olefin Thermoset (COT) resin, overcomes these challenges. The VCJ system uses real-time computer vision to monitor and correct material deposition, ensuring precise geometric tolerances. The COT resin, with its low dielectric loss and stable thermomechanical properties, allows for the creation of subwavelength lattice structures that direct electromagnetic waves with minimal attenuation. \\[The 100 mm diameter Luneburg lens, tested across the Ka-, U-, and W-bands, demonstrates exceptional performance, with an aperture exceeding 30 wavelengths and a realized gain above 34 dBi. This breakthrough is particularly relevant for industries in ASEAN countries that are moving towards mmWave frequencies, including telecommunications, aerospace, and defense. For example, in Thailand, where the demand for advanced communication systems is growing, these lenses can enhance the performance of autonomous drones and battlefield networks. In Vietnam, the technology can support the development of satellite ground stations and phased-array radars. In Indonesia and Malaysia, the lenses' high data throughput capacity makes them ideal for AI data centers, automotive radar, and industrial sensing arrays. \\[Inkbit's 3D-printed lenses not only improve the efficiency and performance of RF and mmWave systems but also reduce the complexity and cost of manufacturing. By eliminating the need for multi-part assemblies, these lenses can be produced more quickly and with fewer errors. This is especially beneficial for factories in ASEAN, where cost-effectiveness and rapid production are key considerations. \\[For factory buyers in ASEAN, the availability of these 3D-printed lenses opens up new opportunities for innovation and competitiveness. Inkbit is currently working on custom projects with industrial partners and offers standard evaluation lenses for sale on their website. Engineering teams can now test these components within their own RF workflows, enabling them to stay at the forefront of technological advancements. \\[In summary, Inkbit's 3D-printed GRIN lenses represent a significant step forward for mmWave technology in ASEAN. By providing a more efficient, cost-effective, and scalable solution, these lenses can help factories in the region enhance their capabilities and meet the demands of modern, high-frequency applications. As the technology continues to evolve, it will be exciting to see how ASEAN factories leverage this innovation to drive growth and innovation in their respective industries.]
