Technology & Products
Key Products
Industrial-grade metal 3D printing (SLM) full-chain solutions: design/modeling, rapid prototyping, small-batch production, and on-demand spare parts; titanium, high-temp alloys, mold steel, CoCr; ±0.1mm precision.
Technological Advantage
Combines advanced multi-axis motion planning with LLM-grade multimodal AI to achieve support-free printing and ±0.1mm precision across challenging materials like high-temperature alloys.
Differentiation
Value Proposition
Solves the reliability and quality-control bottlenecks of metal 3D printing by treating the manufacturing process as a dynamic data stream, using AI to provide real-time monitoring and self-correcting process control.
How They Differentiate
Dreame (追觅) ecosystem-incubated metal AM unit combining SLM process depth with smart control/AI/motor tech from parent; full-chain industrial solutions vs pure equipment sales; early focus on commercial space and other high-value verticals.
Market & Competition
Target Customers
Industrial manufacturers requiring high-precision, complex metal components, particularly those using high-performance alloys.
Industry Verticals
Aerospace, Medical (Implants & Tools), New Energy Vehicles (NEV), High-end Mold Manufacturing, Energy & Power Generation
Competitors
Farsoon Technologies; BLT (Bright Laser Technologies); Xi'an Sailong Metal Materials
