Greenstone-Tech, together with six academic and research institutions, recently published a joint paper in the prestigious international journal Computer-Aided Design<\/em> titled \u201cChallenges in Topology Optimization for Hybrid Additive\u2013Subtractive Manufacturing: A Review.\u201d<\/em> The study presents the latest research progress in the field of Hybrid Additive\u2013Subtractive Manufacturing (HASM).<\/p>\n\n\n\n

What is Hybrid Additive\u2013Subtractive Manufacturing (HASM)?<\/strong><\/h5>\n\n\n\n

Hybrid Additive\u2013Subtractive Manufacturing (HASM) is a revolutionary manufacturing technology that combines the advantages of additive manufacturing (3D printing) and subtractive manufacturing (CNC machining). This approach enables the efficient production of complex-shaped components in a single setup.<\/p>\n\n\n\n

While HASM excels in producing complex geometries, it still faces challenges in processing simpler mechanical parts, mainly due to relatively higher costs and limited economic efficiency.<\/p>\n\n\n\n
