Background technology
The concept of the three Dimensional Printing of Rapid Prototyping technology the earliest people such as the scansE.M. of Shi You Massachusetts Institute Technology (MIT) and cimaMJ. proposed in 1992.3 D-printing is a kind of RP technique based on drop reaction-injection moulding, individual layer printing-forming is similar to ink jet printing process, under the excitation of data signal, make the liquid material in printhead working chamber form drop (Droplets) or form drop by jet in moment, with certain frequency speed, from nozzle, spray and be ejected into assigned address and successively pile up formation Three-dimensional Entity Components.Have at present multiple 3D printing technique, conventional technology comprises binding material 3 D-printing, photocuring 3 D-printing and melted material 3 D-printing etc. at present.
But in the process of printing at 3D, because the material of printing is generally plastics, at the initial stage of Workpiece shaping, the temperature of printed material is relatively high, and in process of setting, temperature can have greatly changed, and printed material in process of setting due to the reason such as inhomogeneous of expanding with heat and contract with cold, the part of having printed can be out of shape in perk, not only affect the following process of 3D printer in print procedure, also can print the moulding accuracy of workpiece, seriously restrict the development of 3D printing technique and popularize.
Especially at the FDM(of 3D printer melted extrusion modeling) technical field, the heat that traditional workbench produces after need to switching on by heating resistor softens ABS product bottom surface, to increase its viscosity, prevent from warping, but when small product size is larger, the internal stress of its contraction is larger, still cannot avoid product warpage issues, thereby affects Forming Quality.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of bad phenomenon such as warpage or deformation that prevent, and the vacuum suction formula 3D that effectively improves Forming Quality prints anti-deformation device.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of vacuum suction formula 3D prints anti-deformation device, comprise workbench, on this workbench, offer the vacuum sucker that is distributed in workbench upper surface, workbench is also equiped with is convenient to the gas-tpe fitting that is connected with vacuum-pumping equipment, and vacuum sucker is communicated with described gas-tpe fitting.
Wherein, described vacuum sucker is at least 12, and vacuum sucker is uniformly distributed in the upper surface of workbench.
Wherein, described gas-tpe fitting is positioned at the side of workbench.
Wherein, described vacuum-pumping equipment comprises vacuum generator and the magnetic valve being communicated with vacuum generator, and this magnetic valve is communicated with pneumatic supply, and the suction hole of vacuum generator is communicated with described gas-tpe fitting.
Wherein, between described magnetic valve and pneumatic supply, be communicated with check valve and filtering pressure reducing valve.
Wherein, described vacuum generator is connected with detection of negative pressure table.
Wherein, described vacuum generator and the magnetic valve being communicated with vacuum generator are at least four groups, and described vacuum sucker is at least 12, and described in each, gas-tpe fitting is communicated with at least three vacuum suckers.
The beneficial effects of the utility model are: the utility model provides a kind of vacuum suction formula 3D to print anti-deformation device, comprise liftable workbench in 3D printing device, on described workbench, offer the vacuum sucker that is distributed in workbench upper surface, workbench is also equiped with is convenient to the gas-tpe fitting that is connected with vacuum-pumping equipment, and vacuum sucker is communicated with described gas-tpe fitting.Vacuum-pumping equipment is when work, vacuum sucker is in vacuum suction state, 3D printer is after printing finished piece(s) the most the lower layer of, aspiration effect due to vacuum sucker, this layer of structure is adsorbed on the upper surface of workbench, thereby effectively prevents that the structure sheaf of having printed from deforming, simple in structure, manufacture difficulty is lower, practical.
