The innovative SLS 3D printing is particularly well suited for components which combine complex geometries as well as internal structures or thin wall structures. Components manufactured with SLS 3D printing have excellent mechanical properties and are comparable in strength to injection-moulded parts.
SLS 3D printing is now considered a process which can work at high speed. Not least due to the fact that lasers can scan the powder material at comparatively high speeds and melt it at the same time.
In addition, the accuracy achievable by laser is very high and is in the range of fractions of millimetres. Methods which use a layered structure which are used in other processes such as industrial FDM 3D printing are much less accurate in comparison.
Another advantage of SLS 3D printing is the three-dimensional production of the components in the printing process, which is achieved by so-called nesting. This is understood to mean the very close spatial placement of the individual components next to each other. So the production space in the SLS 3D printer is optimally utilised.
The optimisation is carried out by means of suitable software, which offers an enormous productivity advantage due to very close placement. These components are isotropic, i.e. uniformly loadable in all directions. In contrast to other additive manufacturing processes, in which there is generally no load in the Z direction due to the separation of the layers.
