Beschreibung
Zusammenfassung:	The invention relates to a method for manufacturing a cosmetic product applicator comprising a gripping part and an applicator part having bristles or teeth. The method comprises a step (S1) of additive manufacturing by sintering a powder of a plastics material followed by a depowdering step (S2) and a post-treatment for the removal of particles that have become detached from said cosmetic productapplicator or are partially sintered, the post-treatment comprising the steps of: blasting (S4); and ionizing blowing (S5). This method allows the removal of particles likely to be irritating, for example with a size greater than 500 micrometres, while being suitable for industrial production. The invention also relates to an associated production method. 本发明涉及用于制造化妆品施涂器的方法，该化妆品施涂器包括握持部分和包含刷毛或齿的施涂部分。该方法包括通过烧结塑料材料粉末的增材制造步骤(S1)，之后是脱粉末步骤(S2)以及用于去除从所述化妆品施涂器脱离的颗粒或部分烧结的颗粒的后处理，该后处理包括以下步骤：-喷砂(S4)；和-电离吹扫(S5)。这种方法使得能够去除可能是刺激性的颗粒，例如尺寸大于500微米的颗粒，同时适合工业生产。本发明还涉及相关的生产方法。
