Additive Manufacturing (AM) to produce parts of optical systems is gaining popularity due to design flexibility and functional integration. However, one of the significant challenges in the field of AM for optical systems is the limited manufacturing accuracy compared to traditional manufacturing methods. This causes an increase in manufacturing and assembly errors, which affects the fit and function of the produced parts and therefore the performance of the optical system. This work aims to reduce the negative impact of manufacturing and assembly errors on optical performance, as exemplified in practice by additively manufacturing housings and lens mounts for a Raman spectroscopy system. For this, the simulated optical system of a Raman spectrometer is used to perform the optical tolerance analysis, such as identifying critical components and sensitivity analysis. The Manufacturability of additive manufacturing is then evaluated by measuring printed standard specimens. According to optical and mechanical tolerance analysis, design and manufacturing problems can be found. Then the structure is optimized using the design flexibility provided by additive manufacturing, and accumulated errors from assembly and manufacturing are reduced by minimizing the number of installed components. Measuring the intensity of the Raman signal revealed that the improved design reduced the accumulated errors in the mechanical structure. In addition, the signal-to-noise ratio is significantly enhanced by 265 % compared to the non-optimized design. Hence, this design optimization based on tolerance analysis is an effective methodology for enhancing the performance of additively manufactured optical systems from the perspective of AM technology development in optical domain.

Additive manufacturing offers great potential in geometric design through the layer-by-layer production of components. This is often used in the development of additively manufactured components to make components lighter. An even greater reduction in mass is possible if several components are combined into a more complex component. However, as complexity increases, so do the manufacturing costs, due to a higher demand for supporting structure, reworking and longer production time. Especially for complex components, which make poor use of the space available in the additive manufacturing system, component separation can be a useful way of reducing manufacturing costs. Therefore, a procedure for automated component separation is presented, which determines an optimal cutting plane with respect to the manufacturing costs. The presented procedure is evaluated using two exemplary components where a reduction of manufacturing costs up to 54 % could be achieved.
