Technical Field

[0001] The utility model relates to the field of 3D printing, in particular to a material recovery device for a light-curing 3D printer. Background Art

[0002] Photocuring 3D printing technology is a common 3D printing method. Its principle is to use ultraviolet light to cure photosensitive resin or other photosensitive materials to build objects layer by layer. During the printing process, there may be residual or uncured parts spilled on the workbench of the 3D printer, which needs to be recycled to reduce waste and environmental impact.

[0003] The existing material recycling on the 3D printer workbench is that the staff uses a scraper and a wire brush to remove the residual printing material from the workbench and then collect it. However, since the printing material is recycled manually, it is time-consuming and labor-intensive, resulting in low recycling efficiency of 3D printing materials.

[0004] Therefore, a light-curing 3D printer material recycling device is now developed that can automatically recycle the printing materials remaining on the 3D printer workbench, reduce the labor intensity of the staff, and improve the recycling efficiency of 3D printing materials.
