Description
Technical field
The utility model relates to a kind of 3D printer bottom frame, and a kind of 3D printer bottom attemperator, belongs to 3D device fabrication equipment manufacturing technology field specifically.
Background technology
3D printer, i.e. a kind of machine of RP technique, it is a kind of taking mathematical model file as basis, uses powdery metal or the plastics etc. can jointing material, carrys out the technology of constructed object by the mode of successively printing. Past, its field such as mould manufacture, industrial design of being everlasting was used to modeling, showed the direct manufacture for some products just gradually.
The 3D printing technique of main flow mainly comprises four kinds now: Stereolithography (SLA), three-dimensional powder bonding (3DP), selective laser sintering (SLS), fusion sediment rapid shaping (FDM); Wherein, based on Stereolithography technology, although the 3D printer precision of three-dimensional powder adhesive technology and Selective Laser Sintering is higher, suitable material is also more extensive, often need larger power, technology more complicated, equipment cost, maintenance cost and material cost are all very high.
Fusion sediment rapid shaping (FDM) is called again fuse deposition, and it is by thread heat-fusible materials heating and melting, is squeezed and is gushed out by the shower nozzle with a minute nozzle. After hot melt material fusing, from shower nozzle ejection, be deposited on the material that print job deck plate or front one deck solidified, temperature starts to solidify after lower than solidification temperature, forms final finished by the accumulation layer by layer of material.
3D printer bottom is incubated object alice when being used for preventing from printing, because the raw material that use are now all ABS and PLA, owing to expanding with heat and contract with cold, can cause the object alice of printing, and the words of use hott bed can prevent alice; Existing 3D printer bottom insulation adopts Electric heating, this structure is little without temperature measuring equipment, heating surface (area) (HS, temperature is wayward, thereby easily flake while making to print ground floor, material cannot stick on hotbed, affect printing effect and make, and this kind of structure is only applicable to miniprinter, cannot meet industrial requirements, processing cost is high.
Utility model content
Technical problem to be solved in the utility model is, for the shortcoming of above prior art, a kind of 3D printer bottom attemperator is proposed, adopt circulating fan and rational air channel to make air in inner loop, reduce inner cold spot, be equipped with multiple temperature control measuring points, ensure that temperature is even, greatly improved the efficiency of utilization of bottom attemperator.
In order to solve the problems of the technologies described above, the technical solution of the utility model is achieved in the following ways: a kind of 3D printer bottom attemperator is provided, comprise frame, fin heater, blower fan and guide duct, frame is the closed frame structure with cavity, in cavity, be provided with hydraulic barrier, cavity is divided into snakelike air channel, fin heater is installed in air channel, be provided with air inlet and air outlet communicates with the two ends in snakelike air channel in the end of frame, the air inlet of frame is connected with the air outlet of blower fan, the air inlet of blower fan is connected with the air outlet of frame by guide duct.
The utility model further limits technical scheme: aforesaid 3D printer bottom attemperator, frame is welded by shape, has ensured the intensity of frame lathe bed, makes technical grade product that stand stretch can not occur on substrate.
Aforesaid 3D printer bottom attemperator, the cavity inside of frame and air inlet thereof and air outlet place are all provided with temperature measuring head, feed back constantly frame internal temperature, ensure that temperature is even, to meet the demand of Industrial Printing.
Further, aforesaid 3D printer bottom attemperator, heat-preservation cotton is installed in frame surrounding and bottom thereof, prevents that heat from distributing to the surrounding of frame, provides stable heat to printer bottom substrate, improves efficiency of utilization.
The beneficial effects of the utility model are: the utility model adopts fin heater that stable thermal source is provided, guarantee bottom substrate quick heating, larger heating surface (area) (HS can be provided, and adopt circulating fan and rational air channel to make air in inner loop, and reduce inner cold spot, be equipped with multiple temperature control measuring points, guarantee temperature is even, and in the surrounding of bottom, aluminium silicate wool insulation material is set, reduce the utilization rate of heat loss raising heat energy, to meet the demand of large platform Industrial Printing.
