Description
Technical field
The present invention relates to printing devices, and in particular to 3D printing nozzle and 3D printing equipment.
Background technology
3D printing (3D printing), i.e. a kind of sci-tech product of rapid shaping technique.It is a kind of with mathematical model text
Based on part, with powdery metal or plastics etc. can jointing material, come the technology of constructed object by way of successively printing.
3D printing head then forms 3D solid, print head is mainly by squeezing out printing raw material on 3D printing platform
Using the continuously extruded of imaging printing raw material, the printing raw material of molten is squeezed out by the spout of nozzle, then molten is beaten
It prints raw material layer upon layer and realizes three-dimensional body shaping.Due to passing through using layering accumulation method shaping, such as by PVC linear materials
Stepper motor band moving gear rotates, and PVC material is sent into nozzle by gear pressure, utilizes the thermosol of PVC material, cooling solidification
Principle, heating are dissolved to be sprayed after fluid, successively eventually form the stereoscopic article of various required shapes to the cold；Printing metal be then with
High function laser or electron beam are heat source, successively dissolve metal powder, eventually form required cubic metal characters or patterns object；Print gypsum
It is then to spray glue, is successively bonded to realize gypsum object；And it is then using injecting type nozzle mode, by chalk to print chocolate
Power successively sprays printing and waits.Therefore the printing shaping time is generally all very long, and the connection between layers of printable layer is only
It is that postcooling is cohered by the printing raw material of molten, so, the printing raw material not cooled down completely can deform due to dead weight,
Especially be in itself soft printing raw material more very, while after placing a period of time, also result in and separate between layers.
For example, in some cases, the printing raw material of printing raw material such as epoxy resin need plus curing agent or its
Its additive, particularly soft printing raw material.If batch mixed, the printing raw material of mixing has little time to be finished in time, then remaining
Printing raw material can cure, and batch mixed is few then not enough.
For this reason, it may be desirable to seek a kind of technical solution, at least to mitigate the above problem.
