3 Terms and definitions
The terms and definitions defined in GB/T 35351 and the following apply to this document.
3.1
In the additive manufacturing process, the microscopic elements (including material composition and/or structure) of the product are changed to form a continuous (or
An additive manufacturing process that achieves continuous (or discontinuous) gradient changes in its performance and function.
3.2
By controlling two or more material components from one direction (one-dimensional, two-dimensional or three-dimensional) to another direction continuously or discontinuously
A non-homogeneous material that changes so that the performance and function of the product change gradually.
3.3
By adjusting the material structure (microstructure or lattice structure) to change continuously or discontinuously in space, the performance and function of the product can be changed in a gradient manner.
A heterogeneous structure.
Note. Typical microstructure or lattice structure functional gradient changes include variable density, variable stiffness, etc.
3.4
Single material functional gradient additive manufacturing single material FGAM
Using a single material, functionally graded additive manufacturing can achieve integrated manufacturing of functionally graded structures and macro-geometry
Craftsmanship.
3.5
Multi-material Functional Gradient Additive Manufacturing multi-material FGAM
Use two or more materials to achieve integrated manufacturing of material composition gradient and macroscopic geometry using functional gradient additive manufacturing
