Description
Technical field
The utility model is related to 3D printing technique field, specifically a kind of new 3D printer hot junction.
Background technology
The fuse species that FDM type 3D printer adopts is a lot, and the temperature of the minimum deliquescing of fuse is a lot of to be less than 70 degree.In addition
In order to improve printing precision (minimizing thickness), the discharging aperture of the extruder head of current FDM printer progressively diminishes, on market
A lot of machines are had to adopt the even more little extruder head aperture of 0.2mm, the conveying dynamics for this extruder is also stepped up.Far-end squeezes
Go out machine due to its extruder and hot junction separate design, need fuse that extrusion force is sent to from extruder the extruder head in hot junction,
Stress therefore on fuse becomes big, once there being space fuse to be easier to distort.Old hot junction non-complete due to employing
All-sealed structure, easily torsional deformation in hot junction in fuse, leads to discharging not smoothly.

Go out connector；The inside of described cartridge fuse is provided with 3D printing fuse, and cartridge fuse surrounds 3D printing fuse, one of 3D printing fuse
Divide and stretch out cartridge fuse.
As further program of the utility model：Described radiator is grid-like, and radiator is evenly spaced in end body
Outer surface.
As further program of the utility model：The bottom shape of described extruder head is cusp-shaped.
Compared with prior art, the utility model beneficial effect：
This new 3D printer hot junction, the structure in optimization design hot junction is so that fuse has been at after entering hot junction
In one airtight space, fuse does not have spatial warping to deform, and completely solves due to the torsional deformation of 3D printing fuse and leads
The problem that gets stuck causing, is particularly being beaten using flexible material (TPU and elastomeric material etc.) and low melting point (compound PLA material etc.) 3D
Print material ages fruit is particularly significant.
