The utility model discloses an extrusion device and 3D printing equipment. The extrusion device comprises a box body and at least two sets of extrusion assemblies. The at least two extrusion assemblies are arranged on the box body and used for conveying consumables in the preset conveying direction. Each set of extrusion assembly comprises a first extrusion rolling piece and a second extrusion rolling piece, the first extrusion rolling pieces and the second extrusion rolling pieces are rotatably arranged on the box body, and the first extrusion rolling pieces and the second extrusion rolling pieces are arranged in a spaced mode so that a feeding gap used for conveying consumables can be formed between the first extrusion rolling pieces and the second extrusion rolling pieces. The first extrusion rolling piece and the second extrusion rolling piece can move relatively to get close to or get away from each other, and then the size of the feeding gap is adjusted. The at least two extrusion assemblies are arrange
