The sector includes core metal 3D printing players such as Bright Laser Technologies, Farsoon Technologies, Advanced Technology & Materials, and UnionTech. Rising institutional interest reflects the capital market's recognition of the 3D printing segment's evolution from 'concept hype' to 'industrialization validation,' especially as batch-scale applications in additive manufacturing continue to expand in areas like commercial aerospace, consumer electronics, and healthcare. The valuation logic for the sector is gradually gaining fundamental support.
