Abstract: A nozzle adjustment device for a three-dimensional forming equipment assembly includes a first guiding block, a second guiding block, and a moving block. The first guiding block has a first inclined surface and a first bottom surface which is parallel to a printing platform. The first inclined surface and the first bottom surface form an acute angle therebetween. The second guiding block has a second inclined surface. The moving block is located between the first guiding block and the second guiding block. The moving block has a third inclined surface, a fourth inclined surface, and a second bottom surface. The second bottom surface is parallel to the printing platform, and has a nozzle disposed thereon.
