The quality evaluation of SLS nylon 3D printing laser sintered parts involves the use requirements of the formed part. If the formed part is required to be a hollow object, then the number of cavities in this part and the size distribution of the cavities are one of the quality indicators. But in the general manufacturing industry, mechanical properties and dimensional shape accuracy are two important quality indicators of their prints.
In the actual forming process, the machining accuracy and mechanical properties of the parts are always determined by the machining conditions and materials, and the performance and accuracy of a machined part are evaluated intuitively.
In the general forming method, the accuracy of the formed part is mainly reflected in three aspects:
① the dimensional accuracy of the formed part;
② the shape accuracy of the formed part;
③ the surface roughness of the formed part.
Similarly, in SLS nylon 3D printing, the accuracy of the formed part is mainly reflected by these three aspects. However, due to the fundamental difference in the cause and mechanism of forming errors, the method of controlling the precision of forming parts in 3D printing is also fundamentally different from that in general forming methods.
The above is the analysis of the dimensional accuracy of SLS nylon 3D printing introduced by JS Additive, hoping give you for reference.
