2022年11月初，全球规模最大的增材制造展览会Formnext在法兰克福举行，除了众多令人印象深刻的组件，格劳博还展出了其首款3D打印系统GMP300。该专业展会表明，增材制造早已超出了原型设计和刀具制造的范围，并且已经在许多工业领域中成功用于对外型和材料有个性化要求的小批量生产。

      凭借液态金属打印系统GMP300，格劳博不仅证明了其在机械制造领域的专业知识，更是展示了一种以线材为原材料的新型高性价比3D打印工艺。通过加工不同的铝合金，即使是以前使用铸造工艺生产的小批量产品也可以高效、经济地生产。由于系统灵活性改善、材料利用率增高以及后处理工作的减少，液态金属打印技术也可以用于高效地生产单个零部件。

     由于该工艺是微铸造工艺，打印件的微观结构和材料性能可与铸件相媲美。打印的零部件不受任何压力干扰，也不需要任何热后处理步骤。市场已经对液态金属打印技术和GMP300表现出了极大的兴趣，不仅因为它的理念新颖，还因为其优势突出，技术潜力巨大。因此，除了其他铝合金之外，格劳博的开发计划还包括铜等新材料，并持续进一步开发工艺，以通过提高制造过程的自动化程度来提高零部件的复杂性和成本效益。

At the beginning of November, the leading trade fair for additive manufacturing, Formnext, took place in Frankfurt, where GROB presented its first 3D printing series machine GMP300 in addition to numerous impressive components. At the trade fair, it became clear that additive manufacturing has long since gone beyond the scope of prototyping and tool manufacturing and is already being used successfully in many branches of industry for the production of small series with very individual requirements in terms of geometry and material.

With its GMP300 Liquid Metal Printing (LMP) machine, GROB is not only demonstrating its expertise in mechanical engineering, but is also showing a new and cost-effective 3D printing process that uses wire as a starting material. By processing various aluminum alloys, even small batches can be produced efficiently and economically that were previously manufactured using casting processes. However, individual parts can also be produced efficiently with LMP technology due to the system flexibility, the high degree of material utilization as well as the reduced post-processing effort.
