Problems solved by technology

Although the technology disclosed in this patent can prevent the nozzle from dripping, its structure is relatively complicated
[0008] In addition, the current heating method of 3D printers based on the fused deposition method is mostly the resistance wire directly heating the nozzle, which makes it difficult to quickly replace the nozzle

Embodiment Construction

[0057] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0058] Such as figure 1 As shown, the fused deposition type 3D printer that can quickly replace the printing nozzle of the present invention includes a base plate 1 at the bottom, a printing frame, a printing head 6, and a driving printing head 6 mounted on the printing frame along the directions of the X axis, the Y axis and the Z axis. As for the moving kinematic mechanism, in this embodiment, the Z-axis direction is the vertical direction, and the X-axis, Y-axis, and Z-axis are perpendicular to each other.

[0059] Also include a gas compressor (not shown in the figure) to provide positive pressure for the barrel;

[0060] Vacuum pump (not shown in the figure), provides negative pressure for barrel;

[0061] The control unit (not shown in the figure) is electrically connected with the gas compressor and the vacuum pump, and controls the o...

Abstract

The invention discloses a fused and deposited 3D printer capable of rapidly changing a printing nozzle, which comprises a printing table and a printing head, wherein the printing head comprises: a supporting plate; a printing nozzle made of a metal material and fixed on the supporting plate via a stand of the printing nozzle; a heating device, comprising an electromagnetic induction coil, the electromagnetic induction coil sleeving the printing nozzle and fixed on the supporting plate via a stand of the coil; a cooling device, used for cooling the printing nozzle, and fixed on the supporting plate via a cooling stand; and a control circuit, electrically connected to the electromagnetic induction coil to provide an alternating voltage for the electromagnetic induction coil. The heating mechanism and the printing nozzle mechanism of the fused and deposited 3D printer are separated from each other to facilitate rapid change of the printing nozzle.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a fused deposition 3D printer capable of rapidly replacing printing nozzles. Background technique [0002] 3D printing technology, also known as Rapid Prototyping Manufacturing (RP technology for short), is divided into selective laser sintering (SLS), stereolithography (SLA), laminated solid molding (LOM) and fused deposition according to different molding methods. Molding (FDM), etc. The biggest difference between the fused deposition modeling (FDM) rapid prototyping system and the SLA, LOM, and SLS systems is that FDM does not use a laser system. [0003] Fused Deposition Modeling (FDM, Fused Deposition Modeling) is a molding method that utilizes the thermoplasticity of materials to heat and melt materials such as thermoplastics, extrude the fuse from a heated nozzle, and perform melt deposition according to the predetermined trajectory of the part. [0004] At present, ...
