Compositions or finishing solutions configured to remove unwanted material, such as uncured material or resin, from additively manufactured objects are disclosed herein, in one example, the finishing solution includes a first glycol ether and a second glycol ether and/or a high flash point hydrocarbon, wherein the finishing solution has a flash point of at least 93.3°C. In alternative examples, the finishing solution may also include a third glycol ether, a high flash point alcohol, and/or an acetate of a glycol ether. L'invention concerne des compositions ou des solutions de finition conçues pour éliminer un matériau non souhaité, tel qu'un matériau ou une résine non durci(e), d'objets fabriqués de manière additive. Dans un exemple, la solution de finition comprend un premier glycoléther et un deuxième glycoléther et/ou un hydrocarbure à point éclair élevé, la solution de finition présentant un point éclair d'au moins 93,3 °C. Dans d'autres exemples, la solution de finition peut également comprendre un troisième glycoléther, un alcool à point éclair élevé et/ou un acétate de glycoléther.
