Short summary

In order to contribute to a standardisation and process monitoring of additive manufacturing (AM) processes, a novel referencing approach was developed to improve the assessment of geometric manufacturing and measurement deviations. This is based on a referencing system integrated in the powder bed, which enables a shortening of the measuring loop. The position-stable quartz glass pipes enable more precise specification of lateral manufacturing and measurement deviations during AM.
