Gutaixin Technology (Shenzhen) Co., Ltd. has published an invention patent titled "Non-contact Process Parameter Control System for Metal Additive-Subtractive Manufacturing Based on Directed Energy Deposition (DED)", with publication number CN122033279A and a filing date of February 2026. The system includes a non-contact measurement unit, a DED printing execution unit, a central control unit, and auxiliary function modules. The central control unit uses the non-contact measurement unit to observe the workpiece in real time during processing, generates feedback signals based on deviations between actual and designed values, and controls a robotic arm to drive the DED printing execution unit, galvanometer, and laser, adjusting the laser processing path to achieve closed-loop regulation of both the printing and subtractive processes. This technology enables real-time compensation within layers, intelligent defect identification and repair, effectively eliminates cumulative errors, and reduces defects such as over-deposition, lack of fusion, and over-cutting, eliminating the need for rework. Gutaixin has preliminarily established a full-chain capability in additive manufacturing of "equipment + materials + processes": upstream self-produced metal powders (GH4169, M35, zirconium alloys, titanium alloys, etc.), midstream self-developed industrial-grade metal 3D printers (GM600D), and downstream provision of printing services and backend precision machining support.
