Description

Technical Field

[0001] The invention relates to the technical field of additive manufacturing, and in particular to a manual wiring device. Background Art

[0002] Fused deposition manufacturing (FDM) is a type of 3D printing technology. It melts thermoplastic materials and deposits them into the desired product. Due to its mature process, low manufacturing cost and fast product manufacturing, it has been widely used in strategic and livelihood fields such as medical devices, automobiles, and rail transit.

[0003] Current 3D printing filaments are hard and brittle due to water loss, and are easy to break. In addition, they are prone to breakage during the printing process, resulting in extreme waste of printing consumables.
