Zusammenfassung:	The invention relates to a curing system (170) for an additive manufacturing system, comprising a light source (210), a liquid crystal cell (220) and a first polarizer (230). The light source (170) is configured to emit light at a wavelength suitable for the curing material. The liquid crystal cell (220) is configured to receive light from the light source (170). The first polarizer (230) includes a polyvinyl alcohol (PVA) matrix and an organic dye impregnated in the PVA matrix. 本发明涉及用于增材制造系统的固化系统(170)，其包括光源(210)、液晶单元(220)和第一偏振片(230)。所述光源(170)被配置为发出适合固化材料的波长的光。所述液晶单元(220)被配置为接收来自所述光源(170)的光。所述第一偏振片(230)包含聚乙烯醇(PVA)基质和浸渍于所述PVA基质中的有机染料。
