The part once created with an sls machine is then fired in a kiln and only the ceramic part survives.
Ceramic sintering advantages.
Sintering or frittage is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction.
The general properties of ceramic material present the following advantages.
High wear heat pressure and chemical attack resistance gas and liquids.
Stability in the process of big series.
Products ready for assembly.
Allows making complex geometries.
Cost economy compared with other processes.
Sintering is a ubiquitous processing step for manufacturing ceramics for a diverse set of applications.
Good mechanical characteristics.
Sintering allows to obtain complex shapes directly from the compacting tooling without any machining operation like teeth splines profiles frontal geometries etc.
Sintering happens naturally in mineral deposits or as a manufacturing process used with metals ceramics plastics and other materials the atoms in the materials diffuse across the boundaries of the particles fusing the particles.
