华曙高科以速度、精度与规模推进铜合金3D打印

Copper alloys have long been among the most coveted yet most difficult materials in additive manufacturing. Their extraordinary thermal and electrical properties make them indispensable for aerospace, electronics, and advanced energy systems, but their high reflectivity to near-infrared lasers has historically caused defects, instability, and scalability constraints. Chinese 3D printer manufacturer Farsoon Technologies is addressing this gap through a multi-pronged approach: optimizing beam parameters, refining laser spot precision, and deploying large-format systems capable of production-grade output.

在增材制造领域，铜合金长期以来既是最受追捧、也是最难加工的材料之一。其卓越的热学和电学性能使其成为航空航天、电子和先进能源系统不可或缺的材料，但由于其对近红外激光的高反射率，历史上一直导致缺陷、不稳定性和可扩展性受限的问题。中国3D打印机厂商华曙高科正通过多管齐下的方法解决这一难题：优化光束参数、精进激光光斑精度，以及部署能够实现生产级输出的大尺寸成型系统。

The company introduced a beam optimization strategy targeting CuCrZr, a notoriously reflective alloy, achieving build rates of up to 42 cm³/h using an 80 μm layer thickness, alongside part densities reaching 99.5% via Archimedes measurement. By widening and stabilizing the process window, Farsoon has made it more feasible to handle large-format components without sacrificing consistency. For designers and engineers seeking reliable, production-ready 3D printing models, this breakthrough opens new possibilities for high-performance metal parts.

该公司针对高反射合金CuCrZr推出了一项光束优化策略，采用80 μm层厚实现了高达42 cm³/h的成型速率，通过阿基米德法测量零件致密度达到99.5%。通过拓宽并稳定工艺窗口，华曙高科使处理大尺寸部件变得更加可行，且不影响一致性。对于寻求可靠、可量产3D打印模型的设计师和工程师而言，这一突破为高性能金属零件开辟了新的可能性。

On the precision side, the FS273M platform combines a 55 μm laser spot, 20 μm layer thickness, and fine powder in the 0–25 μm range to achieve feature resolutions down to 0.2 mm. This unlocks direct fabrication of ultra-thin cooling fins at 0.2 mm, TPMS porous structures at 0.3 mm, and thin-wall features as narrow as 0.18 mm, all completed in a single build with no secondary machining required.

在精度方面，FS273M平台结合55 μm激光光斑、20 μm层厚以及0-25 μm范围的精细粉末，可实现低至0.2 mm的特征分辨率。这解锁了直接制造0.2 mm超薄散热翅片、0.3 mm TPMS多孔结构以及薄至0.18 mm的薄壁特征的能力，所有工序均在一次成型中完成，无需二次加工。

Material performance holds up at that resolution too. CuCrZr reaches densities up to 8.88 g/cm³, pure copper achieves thermal conductivity up to 388 W/(m·K), and hardness reaches up to 100 HV. That combination of fine geometry and strong functional output makes this platform particularly relevant for electronic thermal management, precision tooling, and compact high-performance devices where both form and function are non-negotiable.

在该分辨率下，材料性能同样出色。CuCrZr致密度可达8.88 g/cm³，纯铜热导率可达388 W/(m·K)，硬度可达100 HV。精细几何结构与强大功能输出的结合，使得该平台尤其适用于电子热管理、精密模具以及紧凑型高性能设备——这些领域对形态与功能的要求都毫不妥协。

Industrial credibility requires more than benchmark numbers. In 2025, a leading advanced energy research institute deployed Farsoon’s FS621M-Cu system to manufacture a CuCrZr electrode plate under demanding accuracy and performance specifications. The project set extremely high bars for both dimensional fidelity and material behavior, and meeting them marked a meaningful milestone for copper alloy AM moving from controlled environments into high-stakes production.

工业可信度不能仅凭基准数据。2025年，一家领先的先进能源研究机构部署了华曙高科的FS621M-Cu系统，在严格的精度和性能规格下制造CuCrZr电极板。该项目对尺寸精度和材料性能均设定了极高要求，满足这些要求标志着铜合金增材制造从受控环境迈向高风险生产的重要里程碑。

At the system level, the FS621M-Cu runs four 1000W ytterbium fiber lasers at 1060–1080 nm, sustaining process stability across extended build times and complex large-part geometries. Multiple units are now deployed internationally, reflecting growing confidence in the platform’s production readiness.

在系统层面，FS621M-Cu配备四台1000W镱光纤激光器（波长1060-1080 nm），可在长时间成型和复杂大尺寸零件几何结构中保持工艺稳定性。目前多台设备已部署至国际市场，反映出业界对该平台生产准备度的信心日益增强。

Copper has always been a paradox in additive manufacturing, a material whose very strengths make it stubbornly difficult to process. Solving its constraints has become one of the defining technical challenges of industrial metal AM, and multiple players are now converging on it from different angles. At TCT Asia 2025, Eplus3D demonstrated meter-scale copper alloy parts using red-laser technology, with a CuCrZr impeller produced on the EP-M1250 achieving 99.97% density while preserving the material’s superior thermal properties. The company positioned red-laser wavelengths as a solution to the incomplete melting, voids, and inconsistent layer bonding that copper’s low infrared absorption has historically caused.

铜在增材制造中始终是一个悖论：其优势恰恰使其加工变得异常困难。解决其局限性已成为工业金属增材制造领域最具标志性的技术挑战之一，多家厂商正从不同角度切入。在2025年TCT亚洲展上，易加三维展示了采用红激光技术的米级铜合金零件，其中在EP-M1250设备上成型的CuCrZr叶轮致密度达到99.97%，同时保留了材料优异的热学性能。该公司将红激光波长定位为一种解决方案，以解决铜因低红外吸收率而长期导致的未完全熔化、孔隙和层间结合不一致等问题。

Elsewhere, Nikon SLM Solutions developed new parameters for NASA’s GRCop-42 copper alloy, pre-configured for large-format systems like the NXG XII 600 and achieving 99.97% density with consistent results. As these technologies mature, the availability of high-quality premium STL files for metal 3D printing continues to expand, enabling more industries to leverage these advanced materials.
