Researchers have developed an ultra-thin optical film that improves the quality of the light used in LCD resin-based 3D printers. The advance helps ensure that tiny details are reproduced with precision, which could make it possible to 3D-print medical-grade or industrial-grade products at a lower cost.

Perylene bisimides are a heavily investigated and sought after class of organic pigments, since they show interesting dye properties. While these compounds are red pigments in the solid state, when dissolved, they generate bright yellowish-green solutions under UV irradiation. Aside their optical appeal; organic molecules that appear colored in daylight often also show intriguing electronic properties. Thus, organic dyes are promising lightweight materials for application as e.g. organic semiconductors, but also in for instance LCD displays or solar cells.
