      3D printing secondary curing box_UVLED curing oven

      Click:[1161] Publish Time:2021-08-31

               The 3D printing and curing industry is a very popular industry at present. It is a technology that builds objects 

      based on digital model files and uses bondable materials such as powdered metal or plastic to print layer by layer.

               3D printing technology has applications in many industries, such as jewelry, industrial design, architecture, 

      dentistry, model manufacturing, and the automotive industry. However, many models printed on 3D printers are not 

      hard enough. At this time, secondary curing is required. , To make the model harder and better quality. The 3D printing 

      secondary curing box is a special auxiliary equipment specially designed and manufactured for the 3D printing industry, 

      which can dry and solidify the printed 3D model.

               The 3D printing secondary curing box produced by Shenzhen Height-LED adopts a box structure, a built-in 

      control system and a UVLED curing lamp. So, what are the requirements of the 3D printing secondary curing for the 

      curing lamp?

                                                    3D printing secondary curing box.jpg

               The power of the UVLED curing lamp is the radiant energy of the UVLED lamp, also known as the penetration. 

      First of all, it must meet the requirements of the spectral wavelength and power density absorbed by the UV ink 

      (varnish). If the power of the UV curing lamp is not enough, the product will not be fully cured even if the irradiation 

      time is longer and the number of times the UV curing device is passed. On the contrary, it will also cause the surface 

      layer of UV ink (varnish) to age, seal, become brittle, etc. At the same time, the adhesion of the ink (varnish) is not 

      good, which will make the interlayer adhesion of the overprint poor. Because the low-power UV curing lamp cannot 

      penetrate the bottom of the ink layer, the bottom is not cured or cured insufficiently.

               In light-curing 3D printing, photosensitive resin is used, and the printed things are very thin and soft afterwards, 

      so UV light is used for secondary curing. Normally, high light power is beneficial for curing effect, short curing time 

      and strong penetration. According to the characteristics of the photosensitive material, the higher the wavelength 

      and the thickness of the object, the higher the curing power to penetrate, otherwise it may not be able to be cured 

      if it is too thick. Each photosensitive resin has a corresponding material parameter, this can be done by consulting 

      the manufacturer.

             The power of UVLED curing lamp generally needs to meet the requirements of 80~120W/cm, but the greater 

      the power, the greater the heat, so the power should be selected according to the cured product and curing speed. 

      The maximum life of the UV curing lamp is generally 800 to 1000 hours, and it should be replaced when it reaches 

      it, because the intensity of the ultraviolet light emitted by the UV curing lamp at this time will become weaker, which 

      will affect the curing effect. At the same time, it is recommended to clean the surface of the lamp tube and the 

      reflector plate on the surface of the reflector with absolute ethanol at an appropriate time according to the production 

      environment (the amount of dust in the air) during the use period, and then turn the UV curing lamp 90°. This is 

      beneficial for all the UV rays to be effectively radiated to the UV ink or varnish, ensuring a certain penetration.

             Shenzhen Height-LED specializes in the production of uvled curing equipment. The products can be applied in 

      many industries and can be customized. Welcome to consult.
