Advantages of the procedure
- high mechanical and thermal resilience of the parts
- no after cross-linking and only marginal rework necessary
- models are immediately ready for use
- non-sintered material can be reused in succession processes
Examples of use
- fabrication of first integration samples with high mechanical and thermal requirements
- fabrication of prototypes with a low number of pieces (1-50 pcs), at small parts even more (100-500 pcs)
The laser-sintering process bases on plasticizing in layers of powdery material. Installation space temperature has to be adjusted in such a manner, that powder is preheated. Necessary energy for merging single powder grains of each layer as well as tying down to subjacent layer is fed by laser. Afterwards the case is lowered and a new layer of powder can be applied.
Having finished fabrication process the part is removed and non-plasticized powder is abscised.
Normally used materials for plastic-laser-sintering are e.g. polyamide plastics (unfilled and gas-filled). The infiltration of laser-sintering-parts is possible for achieving liquid and gas tightness as well as dielectric strength.
