Description

Technical Field

[0001] The invention belongs to the technical field of plastic recycling, and specifically refers to a 3D printing waste recycling device. Background Art

[0002] 3D printing technology, also known as additive manufacturing, is a manufacturing process that builds three-dimensional objects by adding materials layer by layer. Its advantages lie in its flexibility and creativity, and its ability to quickly produce complex geometric structures and reduce waste in traditional manufacturing. Currently commonly used 3D printing technologies include fused deposition modeling (FDM), stereolithography (SLA), and selective laser sintering (SLS). FDM is the most common desktop technology, which uses thermoplastic materials (such as PLA or ABS) to deposit layer by layer through a heated nozzle; SLA uses ultraviolet lasers to cure liquid resins, which is suitable for high-precision models. SLS uses laser sintering of powder materials (such as nylon or metal) without the need for support structures, making it suitable for the manufacture of complex parts.

[0003] Most of the existing recycling devices are for industrial use. They are large and inconvenient to use. They are not economical for home users and small studios, and it is not realistic to equip them with these devices. The amount of plastic that needs to be recycled at a time is not large, and the waste printed parts generated during the use of 3D printers themselves have good remolding and crushing properties.
