The idea of ‘printing optics’ is simple, and the approach was attempted many times in the past, especially with ‘conventional’ 3D printing processes, but products made using these processes need a lot of postprocessing. 3D printing filaments or resins might be ‘clear’ and ‘transparent’, but do not offer the optical quality and performance as needed in challenging lighting applications. From a process perspective, the layer-wise printing is not able to achieve the smooth surfaces necessary for functional parts and may have high haze values (‘inside rubbish’) that can’t be compensated from the outside of the lens.

Yes, they address that and they say their process doesn’t require post-processing.
