Description
Technical field
The present invention relates to technology of prining, a kind of method and device of power of prining particularly to adjustment solid.
Background technology
It is a kind of form of additive manufacturing technology that solid is printd, and prints in additive manufacturing technology neutral body as if stands
Body printing machine creates out by continuous physical layer.Three-dimensional printing machine for other additive manufacturing technologies,
There is speed fast, low price, the advantages of high ease for use.Three-dimensional printing machine is that can print out one kind of true stereo object sets
Standby, functionally as laser forming technology, shaped using layering processing, superposition, generated by successively increase material three-dimensional
Print object, entirely different with traditional removal materials processing technology.Being referred to as three-dimensional printing machine is to have references to its know-why,
Because the process of layering processing is quite similar with the operation principle of ink-jet printing machine.
At present, three-dimensional printing machine is carrying out three-dimensional when prining of object of prining, and first, gets the mould of three-dimensional object of prining
Type data message；Then, printd according to solid the model data information of object, using the general parameter letter of prining pre-setting
Breath, carries out solid and prints；Finally, obtain solid to print object.
Three-dimensional printing machine can be using melt extruding molding (FDM) technology, and what it adopted prints material for thermoplastic,
Material of prining is extruded after heated fusing in the shower nozzle of three-dimensional printing machine, and material of prining solidifies rapidly, and the material with surrounding
Bonding, obtains a synusia.Each synusia is to pile up to form on last layer, and last layer piece plays positioning to current synusia
And supporting role.With the increase of height, the area of synusia profile and shape all can change, when changing greatly, upper one
Synusia just cannot play positioning and supporting role to current synusia, after the external support structure that is at this moment accomplished by carrying out prining, followed by
Continuous current layer of prining.
Three-dimensional printing machine, during prining, is usually printd using different speed or temperature according to actual needs,
Such as print external support structure when for the stripping in later stage, it is right that the conjugation and synusia between will be printd less than solid
As the conjugation between each synusia in main body, it is accomplished by when prining prining each layer in objective subject using than solid of prining
Piece lower temperature and faster speed are being printd.
At present, using the heating power that the three-dimensional printing machine of FDM technology is adopted be all constant it is impossible to adjustment, will not
Print speed according to set and temperature of prining carries out height and adjusts, this can make set print speed and temperature of prining
Cannot actually reach on implementing or exceed, this can lead to problems with：1st, when the heating power of setting is more than set
Print speed and print temperature requirement heating power when, the power surplus of three-dimensional printing machine, expend electric power；2nd, when setting
When heating power is less than the heating power of set print speed and temperature requirement of prining, power is not printd it is impossible to meet
Speed, what the unit interval melted prints material not, causes the solid finally giving object quality of prining to decline.
