Abstract

Additive manufacturing becomes more widespread nowadays. Selective laser sintering (SLS) as one of the additive manufacturing methods has a high potential because of a wide range of raw materials. In most cases the accuracy of a SLS process depends on the scanner system of the manufacturing laser beam, parameters of the laser beam and working distance. In order to meet higher quality parameters and to provide manufacturing defects correction a measurement system should be integrated in the process. A measurement system should be developed with considering harsh conditions in the process chamber and taking into account features of the measurement object. Thus only non-contact sensors could be applied. Measurement systems based on the photogrammetric principle are more applicable for such tasks. In current paper presented the investigation which was conducted to determine optical compatibility of the measurement system with raw materials. Measurements were carried out with materials heated to an operating temperature and after a melting process. Also, the test samples of different shape were produced with the SLSMachine. The influence of the manufacturing angle was investigated. General recommendations about the compensation of this influence and for location of an object in the powder bed were formulated. This paper presents some research results necessary for detection and prevention of errors during the SLS process. It is an important experience for application and integration of a measurement system as a monitoring instrument during the SLS process.
