Problems solved by technology

It is precisely because of the existence of these corrugated microstructures that the mechanical properties of the printed product are enhanced. However, when printing products that require higher mechanical properties, the corrugated microstructure of the pointed nozzle cannot meet the requirements.

Embodiment Construction

[0021] The core idea of ​​the present invention is to provide an FDM 3D printing platform with ultrasonic-assisted vibration, which can not only increase the corrugated microstructure of the printed product, make the mechanical properties stronger, but also make the bonding between the printing layers more compact, reducing the surface area of ​​the printed product. roughness.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] The first ultrasonic-assisted vibration FDM 3D printing platform provided i...

Abstract

The invention discloses an ultrasonic-assisted vibration FDM type 3D printing platform which comprises a hot bed arranged on a supporting plate. Ultrasonic transducers are fixed to the lower portion of the supporting plate. The ultrasonic-assisted vibration FDM type 3D printing platform is used for making the hot bed generate ultrasonic vibration during 3D printing, and the ultrasonic transducers are fixed to a fixing plate through flanges on amplitude changing poles. By means of the above ultrasonic-assisted vibration FDM type 3D printing platform, the microwave-shaped microscopic structure of a printing product can be improved, the mechanical performance is higher, combination of printing layers is more compact, and the surface roughness of the printing products is lowered.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, in particular to an FDM type 3D printing platform with ultrasonic-assisted vibration. Background technique [0002] FDM 3D printer is a common type of 3D printer, where FDM refers to "Fused Deposition Modeling", which is Fused Deposition Modeling. The materials printed by FDM 3D printers are generally thermoplastic materials, such as wax, ABS, nylon, etc. It is fed in a filament form, and the material is heated and melted into a liquid state in the nozzle, and the nozzle moves along the cross-sectional profile of the part and the filling trajectory, and at the same time extrudes the molten material. The material then solidifies rapidly and condenses with the surrounding material to form a layered section. After one layer is formed, the machine workbench is lowered to a height (that is, layer thickness), and then the next layer is formed until the entire solid shape is formed. In addition t...
