Description
Technical field
The present invention relates to FDM 3D printer detection technique field, lack material, putty particularly to a kind of FDM 3D printer
Detection device.
Background technology
3D printer, also known as three-dimensional printer (3DP), is a kind of machine of a kind of accumulation manufacturing technology, i.e. Rapid Prototyping technique
Device, based on it is a kind of mathematical model file, use special wax material, powdery metal or plastics etc. can jointing material, pass through
Print jointing material from level to level and manufacture the object of three-dimensional.Present stage three-dimensional printer is used to manufacture product.Successively print
Mode carry out the technology of constructed object.The principle of 3D printer is that data and raw material are put in 3D printer, and machine can be according to
Program is created product from level to level.
FDM is the shorthand of " Fused Deposition Modeling ", is fused glass pellet.Generally 2D beats
Print is to complete (in a plane) on a sheet of paper to print, and 3D printing has been the printing of a stereomodel.FDM is popular
From the point of view of utilize high temperature that material melts is become liquid exactly, after being extruded by printhead solidify, finally on solid space arrange shape
Become three-dimensional real object.
The most traditional desktop FDM 3D printer lacks material detection device to be passed through based on limit switch technology, material
Material pipe advances, thus compresses the shell fragment of limit switch, triggers limit switch and produces signal, and when emptied of material, limit switch is multiple
Position, blackout, whether detection material exhausts in this way.But owing to scarce material detection device is based on limit switch technology, when
During printhead putty, material suspends feeding, and this device just cannot detect.
Therefore, being badly in need of designing novel scarce material, putty detection device, a device solves to lack material simultaneously and asks with putty two
Topic.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of solution cannot detect putty FDM 3D printer lack material,
Putty detection device.
For solving above-mentioned technical problem, the technical scheme is that a kind of FDM 3D printer lacks material, putty detection dress
