Abstract

Due to
the growing number of applications for Additive Manufacturing (AM), an
increasing need for enhanced quality control methods exists. Here optical
measurement techniques are often used for in-situ monitoring in AM. There is a
great potential to standardize and improve applications of optical measurement
devices in accordance to the increasing requirements of measuring tasks. Beside
the optical material qualifications, especially process-oriented changes in
optical effects are of great relevance for in-situ evaluations. The optical
modifications may be attributed to aggregate specific phase transitions coming
along with variable emitted wavelengths. A measuring setup with two
integrations spheres and a heated process chamber have been developed to
analyze the optical interactions of laser radiation and visual illumination with
the powder. The process oriented analysis for selective laser sintering lead to
improved operating conditions in the field of in-situ measurements in
combination with an accurate evaluation of the absorption ratio of the examined
powder.
