In today’s competitive manufacturing landscape, fiber-reinforced composite parts are in high demand across aerospace, defense, medical rehabilitation, and civil engineering. Yet traditional production methods often involve costly filament preparation, long lead times, and limited design freedom. Zhejiang Challen 3D Technology Co., Ltd. (Challenge & Intelligence) is changing that with industrial-grade pellet 3D printing systems that eliminate the need for filament and enable direct use of granular materials—including thermoplastics, fiber-reinforced granules, and metal binder granules.
Founded in June 2022, Challenge & Intelligence specializes in the research, development, and industrial application of 3D printing technology for fiber-reinforced composites. Our core team holds PhDs and Master’s degrees from internationally renowned institutions such as Texas Tech University, Ghent University, and Hiroshima University, bringing over a decade of R&D experience in additive manufacturing equipment, composite material processes, and intelligent control systems. With multiple proprietary intellectual property rights, we have independently developed 3D printing equipment, software, and composite pellet materials that are already successfully deployed in key sectors.
To better serve global customers, we have selected several industrial-grade 3D printing systems that are suitable for containerized transport—making international shipping and setup both practical and cost-effective. Our portfolio covers a wide range of applications, from desktop-scale to meter-scale build volumes, and from robotic arm curved surface printing to gantry-based large-format printing. Whether you need the CI Uni-Print for precise small parts, the CI Robotic AM for multi-axis conformal printing, or the FORCE TRACER for large-format composite molds, our systems combine high precision, low cost, and high efficiency.
The key advantage of our pellet extrusion 3D printing technology is the direct use of granular materials. This eliminates the filament preparation step, significantly reducing both production and transport costs. Our equipment supports fused particle fabrication and fiber-reinforced composite manufacturing, enabling applications such as aerospace 3D printing, low-altitude economy components, composite mold manufacturing, medical 3D printing, and sculpture 3D printing. By integrating multi-axis 3D printing and intelligent control, we help manufacturers achieve complex geometries with industrial reliability.
Challenge & Intelligence is committed to delivering tailored additive manufacturing solutions that match your specific material, size, and application requirements. Contact us today to discuss how our pellet 3D printers and composite 3D printing equipment can lower your costs, shorten your supply chain, and unlock new design possibilities.
