SLS 3D printing produces strong parts due to the following reasons:
1. Strong Layer Adhesion: The laser sintering process creates very strong bonds between layers, resulting in parts with good isotropic properties.
2. Durable Materials: SLS uses durable polymer powders that contribute to the strength of the final part.
3. No Support Structures: The unsintered powder acts as a support, allowing for complex geometries without compromising part strength.
4. High Precision: The precision of the laser allows for tight control over the sintering process, leading to mechanically robust parts.
These factors combine to make SLS-printed parts comparable in strength to traditionally manufactured items.
