Abstract: A remaining printing material measurement method, and an additive manufacturing apparatus are provided. The remaining printing material measurement method is applied to the additive manufacturing apparatus. The measurement method allows for determining whether the remaining printing material in a resin vat is enough to complete the printing of a model to be printed before printing or during printing, which is beneficial to promote a user to add the printing material when the printing material in the resin vat is insufficient, so as to avoid printing delay or interruption caused by not adding printing materials in time and greatly increase the operation efficiency.

Abstract: A rapid prototyping device is provided. The rapid prototyping device includes a frame with a substrate. A printing platform is slidably connected to the frame. A moving assembly includes a display screen assembly corresponding to the printing platform. The moving assembly cooperates with the substrate to move to a leveling position relative to the substrate under the pushing of the printing platform. A suspension member is configured to apply a pushing force, which enables the moving assembly to move away from the substrate, to the moving assembly. The positioning assembly is configured to position the moving assembly in the leveling position. The rapid prototyping device is applied to level the rapid prototyping device.

Abstract: A light source assembly and a printer reduce the loss of light rays, increase the utilization rate of the light rays and avoid the non-uniform light projection while uniformizing and collimating the light rays mainly by means of the cooperation of a lens and a reflector, thereby facilitating uniform curing of a printing resin. The main technical solution is as follows: a light source assembly for a printer, the light source assembly including a light-emitting element, a lens and a reflector. The light-emitting element and the reflector are arranged on two opposite sides of the lens. The reflector cooperates with the lens such that light rays emitted by the light-emitting element are projected after being refracted by the lens and reflected by the reflector. The light source assembly is primarily used for 3D printing.
