Panda3dp.com Guide: Last year, the U.S. introduced the Micronics, a highly cost-effective desktop SLS 3D printer that quickly surpassed $1 million in crowdfunding. However, after being acquired by Formlabs—a company with its own compact SLS printer lineup—the campaign was canceled, sparking heated industry discussions. Now, China has finally entered the scene with a similar desktop model, drawing significant attention from the industry.  

 

 

In March 2025, Panda3dp.com learned that Zongheng Additive Intelligent Technology, a nationally recognized high-tech enterprise and a "Little Giant" in specialized and sophisticated manufacturing, will officially unveil its latest Selective Laser Sintering (SLS) 3D printer—the SLS 1518—at the TCT Asia 2025 exhibition (Booth 8C78). Designed specifically for small and medium-sized enterprises, this cutting-edge printer is priced at just 59,999 RMB. With breakthroughs in technology democratization, intelligent production, and cost efficiency, it is poised to become a disruptive force in industrial-grade 3D printing.
