Below in conjunction with accompanying drawing, the utility model constant temperature 3D printer is further described.

Accompanying drawing explanation

Fig. 1 is the annexation figure in the utility model 3D constant temperature printer between each device.

Detailed description of the invention

As shown in Figure 1, a kind of constant temperature 3D of the utility model printer, wherein the print area 7 of 3D printer is enclosure space;

Constant temperature 3D printer also comprises controller 1, water circulating pump 2, water tank 3, cold type 4, temperature sensor 5 and semiconductor thermoelectric 6; Wherein: controller 1 is PLC or singlechip chip.Semiconductor thermoelectric 6 is a kind of electric refrigeration devices based on thermoelectric cooling, also known as making thermoelectric cooling or semiconductor refrigerating, is a kind of refrigerating method utilizing pyroelectric effect.Different from compressor refrigerator, it is a kind of solid low-temperature receiver, is the crystallization of semiconductor and electronic technology.Semiconductor thermoelectric is once be communicated with direct current, and its one end (hot junction) can produce high temperature, and the other end (cold junction) can produce low temperature.

In the utility model, temperature sensor 5, cold type 4 are arranged in the print area 7 of printer respectively;

Water tank 3, water circulating pump 2 and cold type 4 join end to end the closed cooling recirculation system of formation one;

The cold junction of semiconductor thermoelectric 6 is connected with water tank, to freeze to the retaining in water tank;

Control power supply, the temperature sensor 5 of water circulating pump 2 are connected with controller 1 respectively, and wherein temperature sensor 5 is for monitoring the temperature of print area 7 constantly, and controller 1 is for the keying of controlled circulation water pump 2.

Further, formed to make the bottom of model be more firmly combined with printing bed 8, the hot junction of the semiconductor thermoelectric 6 that the utility model uses is arranged at the lower end printing bed 8, and the hot junction of semiconductor thermoelectric 6 can rotate around a fixed axis, can rotate as required to the hot junction of semiconductor thermoelectric 6.

The operation principle of the utility model constant temperature 3D printer is as follows:

First rotate the hot junction of semiconductor thermoelectric 6, make the hot junction of semiconductor thermoelectric 6 just to printing bed 8, to heat printing bed 8;

Then the bottom of printer model, higher owing to now printing bed 8 temperature, so the surface being attached to printing bed 8 that the bottom of model is close;

Then rotate the hot junction of semiconductor thermoelectric 6, the hot junction of semiconductor thermoelectric 6 is departed from and prints bed 8, form more firm combination with printing bed 8 after the cooling of model bottom, can not alice be formed;

Then successively other position of printer model.Therebetween, the temperature in print area 7 monitored constantly by temperature sensor 5, when temperature departure preset temperature, controller 1 just can touch the power supply of logical water circulating pump 2, current in cooling recirculation system can be according to: water tank > water circulating pump > cold type > water tank direction circulates, and makes the temperature constant in print area 7.

The utility model is on the basis of existing 3D printer, the print area of 3D printer is designed to enclosure space, and introduce temperature sensor, controller and cooling recirculation system, the print area of 3D printer is made to be in temperature constant state all the time, avoiding the alice situation that printer model causes because expanding with heat and contract with cold, making model bottom form good combination with printing bed surface.In addition, under temperature constant state, the overall printing effect of model is more level and smooth, improves printing precision.

Above-described embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
