Description

A kind of intelligent temperature control hott bed of large-scale 3D printer
Technical field
The present invention relates to the printing hott bed field in 3D printer accessory field, more particularly to 3D printer, specifically, it is A kind of intelligent temperature control hott bed of large-scale 3D printer.
Background technology
3D printing technique has technically generally defined a set of system, 3D printing technique is gathered around by development these years Have many advantages, such as, such as:Material can be saved, without rejecting leftover pieces, stock utilization height, the production assembled can be printed Product, production cost is reduced by abandoning tradition production line, or even can also challenge mass production method;Can also it is automatic, Quickly, the design in computer directly and is accurately converted into model, energy direct manufacturing parts or mould, and accomplishes very high Precision and complexity, and in a few hours internal shaping design and exploitation can be allowed to realize the leap from plan to entity, so that Effectively shorten the research and development of products cycle.At present, the applicable industry of 3D printing technique also gradually expands, from product design to mould Design and manufacture, material engineering, medical research, culture and arts, architectural engineering etc. are all gradual to use 3D printer technology, So that 3D printer technology has wide prospect.
3D printing technique is a kind of accumulation manufacturing technology, and it is based on a kind of mathematical model file, with liquid or powder The melt substance of shape is printed material, and " printed material " is stacked up from level to level by computer control, utilizes gluing from level to level Condensation material is superimposed to manufacture the object of three-dimensional, and the blueprint on computer is finally become in kind.In printing shaping process, material Gradually cool down, the material first printed is first cooled down, after cool down after the material that prints, differed due to material cool time or Inhomogeneous cooling is easily caused Material shrinkage degree difference, causes the problems such as alice or shrinkage crack occurs in printout.Therefore, We would generally be provided for heating the hott bed of printed material on the printing bed of 3D printer, by heating hott bed, allow printing The material of semi-finished product out maintains a higher temperature all the time, prevents portion of material is cooled down in advance in print procedure from leading The problems such as there is alice or shrinkage crack in cause.
Using 3D printer when, hott bed energy consumption is larger, one large-scale 3D printer hott bed power it is general 1KW with On, and in order to ensure print quality, the temperature of model bottom will be typically maintained between 50 DEG C~70 DEG C, in order to keep this temperature Degree, whole hott bed will always be in working condition, but actual printing, and printer model is general only to occupy a part for hott bed, The vacant part of hott bed just consumes a large amount of electric energy in vain.
