Description

technical field [0001] The invention belongs to the technical field of additive molding, and relates to an additive and subtractive material manufacturing device and method, in particular to an additive and subtractive material manufacturing device and method for large complex metal structural parts. Background technique [0002] Additive manufacturing technology is also known as 3D printing or rapid prototyping. It is a technology based on digital model files, using bondable materials such as powdered metal or plastic, or fuses, to construct objects by stacking and accumulating layer by layer. Currently commonly used additive manufacturing methods include: laser powder bed fusion, electron beam powder bed fusion, laser coaxial powder feeding, arc fuse forming technology, etc. [0003] Laser powder bed fusion and electron beam powder bed fusion are currently not suitable for additive manufacturing of large parts due to factors such as the size limitation of the molding cavi...
