In additive manufacturing, the 3D printing resolution corresponds to the accuracy of the 3D printers along the manufacturing axes (xyz).
3D printers build objects layer after layer. A distinction must be made between the resolution along the manufacturing axis (layer thickness) and the work plane (a single layer).
The printing resolution along the manufacturing axis relates to layer thickness. With the different technologies, there are many possible resolutions depending on the raw material used. For example, powder-based technologies will have limited resolution based on the raw material’s particle size, while liquid-based technologies will be much more accurate.
In the manufacturing plane, the resolution depends on both the raw material and the technology used.For example, for laser-based technologies, the laser’s impact diameter has a direct influence on the printing resolution. For agglomeration technology des (Zprinter), the printing resolution will be limited by the infiltration of the adhesive in the powder.
To learn more about the 3D printing resolutions of various materials, please refer to our pages about 3D printing materials and modelling guides.
The 3D model designed by the user also has a resolution. For STL files for example, the mesh’s thinness is the CAD model‘s level of detail.
The file resolution should be better than the 3D printer resolution in order to avoid seeing any imperfections generated by the 3D design software. It is unnecessary to have a CAD model with very intricate details, since the printer has limited resolution . The best way is to adapt the file resolution to the technology chosen for printing.
