Chromatic 3D材料在3D打印火箭推进剂领域取得突破

Chromatic 3D Materials, a company specializing in additively manufactured elastomeric and propulsion materials, has announced a major milestone: the successful prototype printing and static fire testing of its 3D printed rocket propellant. The tests were conducted at the Integrated Solutions for Systems (IS4S) test range in Opelika, Alabama.

专注于增材制造弹性体与推进材料的公司Chromatic 3D Materials宣布了一项重大里程碑：成功完成其3D打印火箭推进剂的原型打印与静态点火测试。测试在阿拉巴马州奥佩利卡的集成系统解决方案（IS4S）试验场进行。

The material sustained combustion pressures exceeding 1,800 psi without any structural failure. This achievement marks a significant step forward in developing resilient, next-generation propulsion manufacturing for rockets and defense applications. The propellant achieves energetic loading levels comparable to top-performing conventional propellants while delivering the structural integrity required to withstand high-pressure combustion environments.

该材料在超过1800 psi的燃烧压力下保持稳定，未出现任何结构失效。这一成就标志着为火箭和国防应用开发高韧性、下一代推进制造技术迈出了重要一步。该推进剂在实现与顶级传统推进剂相当的含能装填水平的同时，提供了承受高压燃烧环境所需的结构完整性。

According to Chromatic, these attributes enable propulsion performance on par with today’s fielded systems—with a clear pathway to surpass them. Based on current results, the material has the capability to propel approximately 90% of the U.S. rocket arsenal with equivalent speed and range.

据Chromatic称，这些特性使其推进性能可与当今现役系统相媲美，并具备明确路径实现超越。根据当前结果，该材料能够以同等速度和射程推动美国约90%的火箭武器库。

Beyond matching conventional systems, the propulsion effort leverages multi-material 3D printing to unlock new design options. Chromatic’s process allows propellant to be printed directly onto or within structural components, enabling optimized geometries, improved mass efficiency, and unique thrust control. These changes can translate into increased thrust, extended range, and greater mission flexibility.

除匹配传统系统外，该推进项目还利用多材料3D打印解锁全新设计选项。Chromatic的工艺允许将推进剂直接打印到结构部件上或内部，从而实现优化几何形状、提升质量效率以及独特推力控制。这些变革可转化为更高推力、更远射程和更强任务灵活性。

Founded in 2016, Chromatic developed RX-AM (Reactive Extrusion Additive Manufacturing) as a proprietary platform for 3D printing durable elastomeric materials. Over the past two years, the firm has extended RX-AM to rocket propellant by adapting conventional polybutadiene propellant binder chemistries for its additive manufacturing process. This approach enables a safer, lower-cost, and significantly faster production process while maintaining—and increasingly exceeding—the performance standards required for operational systems.

Chromatic成立于2016年，开发了RX-AM（反应挤出增材制造）作为3D打印耐用弹性体材料的专有平台。过去两年间，该公司通过将传统聚丁二烯推进剂粘结剂化学体系适配其增材制造工艺，将RX-AM扩展至火箭推进剂领域。该方法在维持并日益超越作战系统所需性能标准的同时，实现了更安全、更低成本且显著更快的生产流程。

“These results demonstrate that additive manufacturing is not only viable for defense propulsion—it can drive meaningful performance gains across at least 90% of the U.S. rocket arsenal,” said Dr. Cora Leibig, founder and CEO at Chromatic 3D Materials. “We’re showing that it’s possible to maintain compatibility with existing systems while opening the door to rockets that fly farther, hit harder, and can be produced faster.”

“这些结果表明，增材制造不仅适用于国防推进领域——更能推动美国至少90%火箭武器库实现切实性能提升，”Chromatic 3D Materials创始人兼首席执行官Cora Leibig博士表示。”我们正在证明，在保持与现有系统兼容性的同时，可以打开让火箭飞得更远、打击更强、生产更快的大门。”

Chromatic added that it is continuing to work with government and industry stakeholders to accelerate adoption of additive manufacturing technologies that enhance readiness and supply chain resilience.

Chromatic补充称，公司正持续与政府和行业利益相关方合作，加速采用可增强战备状态与供应链韧性的增材制造技术。

Additive manufactured solid propellant has already progressed beyond early development into live testing. In 2022, X-Bow Systems carried out the first launch of its Bolt rocket using Ballesta engines fueled by 3D printed solid propellant grains shaped for mission-specific requirements. That result demonstrated that additive manufacturing could move propellant design beyond static geometry constraints and into flight hardware, giving engineers more control over how solid motors are configured for launch applications.

增材制造固体推进剂已从早期开发阶段进入实弹测试。2022年，X-Bow Systems使用由3D打印固体推进剂药柱（按任务需求定制形状）驱动的Ballesta发动机，完成了其Bolt火箭的首次发射。该结果证明，增材制造可使推进剂设计突破静态几何限制，进入飞行硬件领域，让工程师对固体发动机的发射配置拥有更多控制权。

Defense-backed work in this area has also centered on constraints that matter for adoption, not just performance claims. In 2025, Firehawk Aerospace secured a $1.25 million Phase II SBIR contract from AFWERX, supported by the Air Force Research Laboratory, to further develop shelf-stable propellant technology for air-to-air weapon systems. Its project scope included formulation development, subscale motor validation, full-scale static-fire demonstrations, lifecycle cost analysis, and performance assessments.

国防支持的相关工作同样聚焦于影响实际应用的关键因素，而不仅是性能指标。2025年，Firehawk Aerospace获得由空军研究实验室支持的AFWERX提供的125万美元第二阶段SBIR合同，用于进一步开发空对空武器系统的可储存推进剂技术。其项目范围涵盖配方开发、缩比发动机验证、全尺寸静态点火演示、全生命周期成本分析及性能评估。

These developments highlight how additive manufacturing is reshaping aerospace and defense manufacturing. For enthusiasts and professionals alike, the same technology driving rocket innovation is also transforming the world of desktop 3D printing. Whether you’re prototyping complex parts or creating detailed models, the availability of high-quality premium STL files has never been greater.

The successful static fire test of Chromatic’s 3D printed rocket propellant is more than a technical achievement—it represents a paradigm shift in how propulsion systems can be designed and produced. By combining advanced materials with additive manufacturing, engineers can now create rocket motors that are lighter, more powerful, and faster to produce than ever before.

As the technology matures, we can expect to see 3D printed propellant systems deployed in a wide range of applications, from tactical missiles to space launch vehicles. The ability to print propellant directly into complex geometries will enable thrust profiles and performance characteristics that are simply impossible with traditional manufacturing methods.

For those inspired by these innovations, exploring the world of 3D printing has never been more accessible. Whether you’re a hobbyist or a professional, finding the right 3D printing models is key to bringing your ideas to life.
