Universal process diagrams for laser sintering of polymers

Selective Laser Sintering Process Management Using a Relational Database

With more and more materials used in the Selective Laser Sintering (SLS) process, it is becoming necessary to use a database to manage the process efficiently. In this paper, a relational database for the SLS process is described. The database includes powdered material data, sintering parameters, machine characteristics, mechanical properties and surface quality of prototypes. Use of this data...

Parametric Optimization of the Process of Selective Laser Sintering Process in Rapid Prototyping Technology- A Review

Compared with traditional material subtractive manufacturing technologies, rapid prototyping is a layer-based material additive process and can produce a 3-D freeform object with a CAD-defined geometric model directly. As one of the advanced rapid prototyping and manufacturing processes, the direct metal laser sintering (DMLS) process gives designers the possibility to build parts of almost any...

Direct Laser Sintering of Ceramics

For more than one decade layer manufacturing technologies assist the development of new products. Due to a layer-wise build-up of a three-dimensional geometry, nearly every complex design is producible in a short period of time. Selective Laser Sintering is a powderbased technique to produce plastic prototypes (Rapid Prototyping) or metal mould inserts (Rapid Tooling). The laser sintering of ce...
