Specific implementation mode
Below by conjunction with accompanying drawings and embodiments, the technical solution of the utility model is described in further detail.?
In specification and attached drawing, each system, structure and component are only symbolically described and shown, but might not describe and show reality
All features of border system, structure and component, such as well known function or structure is described in detail, to avoid unnecessary thin
Festival-gathering keeps the utility model smudgy.It, can many modifications may be made as needed and increase and decrease it should be understood that in practical applications.
Terms used herein should be understood and interpreted that well known to a person skilled in the art meanings to have.For having
The term of particular meaning, will clearly be provided with definition mode in the description it is specifically defined, so as to directly and have no ambiguity
Ground understands.In the whole instruction and claim, word " comprising " should be explained with open meaning, that is, " packet

After be extruded, selectively coating on the table, thin layer is formed after being quickly cooled down, often molding complete a layer cross section, work
Platform declines along Z axis, then carries out next layer of coating, so moves in circles, ultimately forms three-dimensional objects.
Modeling Material is generally thermoplastic material, and backing material is strippable water-soluble material.Although in such as air pressure
Raw material can be powder type in formula FDM3D printer, but the raw material used in desktop grade 3D printer are mainly with the shape of silk
Formula provides.
As previously mentioned, the most common raw material of desktop grade 3D printer have two kinds of PLA and ABS under FDM technology.ABS is one
There is pungent bad smell after the thermoplastic of kind high intensity, burning or melting.PLA, that is, polylactic acid is that one kind biological can drop
The environment-friendly type plastic of solution, it decomposes to obtain glucose through enzyme, then through lactic acid bacteria using the starch of the extractions such as corn, wheat as raw material
Become lactic acid after equal strain fermentations, then chemical synthesis obtains high-purity PLA.Since PLA is non-toxic and tasteless and renewable, so in table
Utilization rate highest in the grade printer of face.On the other hand, exactly because PLA is easy to degrade, especially ultraviolet light and temperature are compared
Sensitivity, so reclaiming is also more difficult.
The utility model waste recycling device exemplary embodiment is described in detail in conjunction with attached drawing, it can be more complete
