Zusammenfassung:	The present application relates to a powder spreading apparatus, comprising an apparatus body, an adjusting assembly and a dust removal mechanism. The adjusting assembly is provided on the apparatus body, and the adjusting assembly faces a powder spreading surface; a first end of the dust removal mechanism is provided on the apparatus body, and the first end of the dust removal mechanism covers the adjusting assembly; a second end of the dust removal mechanism is communicated with the first end of the dust removal mechanism, and the second end of the dust removal mechanism extends out of the apparatus body. The present application further relates to a 3D printing device and a 3D printing system. The present solution can solve the problem that flying dust generated in a current powder spreading process affects the printing quality. La présente demande concerne un appareil d'étalement de poudre, comprenant un corps d'appareil, un ensemble de réglage et un mécanisme d'élimination de poussière. L'ensemble de régl
