The demand of sophisticated components is
continuously increasing, driven by big data, IoT,
and Industry 4.0. Reducing cost and time to market
impacts all levels in a vast majority of products. 3D
printing is typically restricted to additive fabrication
within one material class, structures are limited in
size, shape, surface finish, often requiring supporting
structures. However, 3D printing is increasingly used
in an industrial environment: It provides fast and
low-cost prototyping. Many 3D printers are based on
laser processing such as selective laser sintering or
melting (SLS/SLM), or stereo lithography (SLA). These
techniques have in common that they are restricted
to a layer-by-layer fabrication of workpieces in
additive working steps, thus resembling a more 2D
bottom-up method. For high precision structures
and high surface quality with an industrial scale
throughput as required for photonics packaging and
for optics for imaging, illumination, sensor, or medical
purposes, respectively, their precision is by far not
good enough. This prevents to use 3D printing for
high quality photonic components.
High precision 3D printing (HP3DP) is a powerful
tool for rapid prototyping of miniaturized designs in
automated, scalable processes, providing a real 3D
technique suitable for the fabrication of optically
high-quality surfaceswith industrial scale throughput,
highest resolution and a unique degree of freedomof
structure generation. Most of the legacy processes
nowadays needed for complex structure fabrication
can be simply avoided, enabling a significant
reductionof resources, of production cost and time to
market. The usefulness of HP3DP to be implemented
in industrial work flows will be demonstrated by
discussing different application scenarios, ranging
from LED to laser die packaging, micro optical
elements and arrays for rapid prototyping of novel
designs up to the manufacturing level. Finally, the
step from prototyping to volume production will
be demonstrated, providing a sophisticated level of
manufacturing.
