Under their topic for this year’s trade fair ‘We Add Safety to Additive Manufacturing’, the Bundesanstalt für Materialforschung und -prüfung (BAM) will be presenting a patented measuring device for high temperature laser profilometry.
The new measuring method enables the use of laser scanning technology with temperatures of up to 1700 degrees Celsius for the first time. Consequently, the size and form of complex components can be measured during burning or annealing, and changes that emerge during the process can be detected. Any Deviations that may later result in the component failing can thus be identified.
The measuring device can be put to use for various manufacturing processes in the future including: the production of additive or conventionally manufactured ceramic components and also the development of metallic components for high temperature applications.
Modern production methods and increased quality requirements demand the use of more integrated and process-related measuring methods. In light of this, BAM has developed an innovative high temperature laser profilometer. This method involves a laser beam being widened and directed onto the sample which rotates within the measuring chamber. The scattered light trace reveals the shape of the sample.
“One advantage of this method is its high laser intensity. This allows measurements in temperatures of up to 1700 degrees Celsius”, explains BAM expert Dr Ralf Müller. “In addition, the device records the measured values so quickly that we can also utilise it during sintering.” With this, even temporary deviations from the sample geometry can be uncovered during the burning process. This effect, referred to as temporary warpage, can ultimately lead to component failure.
Successful cooperation with medium-sized enterprises
The development of the high temperature laser profilometer is also an example of the successful cooperation BAM has had with medium-sized enterprises. BAM had already developed a predecessor device in 2007, which characterised the flat surface of ceramic samples in temperatures of up to 1000 degrees Celsius. Since 2013, the scientists have been working on the demonstration device which can be seen at the Hannover Messe.
From the onset, BAM cooperated with medium-sized enterprises specialised in developing measurement technology and laboratory furnaces for the development of this measuring method.
The measuring device is currently being brought to market maturity. BAM will continue to use its expertise in high temperature laser profilometry to test practice-relevant questions, to deepen the scientific basis of the process and to support the dissemination of the method through publication activities.
Where to find BAM at the Hannover Messe 2019
The main theme of BAM’s exhibition this year is additive manufacturing. Under the slogan "We add Safety to Additive Manufacturing” visitors will be able to gain insight into BAM's research in this area. BAM is also presenting its commitment to promoting spin-offs (stand C51 in the Research & Technology area in hall 2).
BAM will provide information on the quality assurance of offshore wind turbines in the same hall at the BMWi trade fair stand (hall 2, stand C28).

BAM promotes safety in technology and chemistry.
As a departmental research institute of the German Federal Ministry for Economic Affairs and Energy, BAM performs research, testing and offers advisory support to protect people, the environment and material goods. Its activity in the fields of materials science, materials engineering and chemistry is focussed on the technical safety of products and processes.
BAM’s research is directed towards substances, materials, building elements, components and facilities as well as natural and technical systems important for the national economy and relevant to society. It also tests and assesses their safe handling and operation. BAM develops and validates analysis procedures and assessment methods, models and necessary standards and provides science-based services for the German industry in a European and international framework.
Safety creates markets.
BAM sets and represents high standards for safety in technology and chemistry for Germany and its global markets to further develop the successful German quality culture "Made in Germany“.
