Definitions

  • the invention relates to a method for producing a micro component, the use of a printhead which works according to the ink printing principle and a device for producing a micro component.
  • microcomponents which for example comprise plastic or consist of plastic
  • injection molds which are then sprayed out with the liquid plastic. After solidification, the microcomponent can be removed from the mold.
  • a disadvantage of these manufacturing processes is that the manufacture of the injection molds is complex and expensive. Especially if you only want to produce a prototype.
  • the starting material is spherical mig before, similar to the well-known metallic sintered materials.
  • the balls are then applied in layers to a carrier by means of a suitable device, to which they may be fixed by stabilizing measures. If the component is applied in layers, the balls can be melted by subsequent heat treatment, so that the individual balls connect to one another and thus form the macroscopic component.
  • the disadvantage here is that only components that are at least 5 to 10 mm in size can be produced. In addition, the contour accuracy of the components is not sufficiently good in some cases.
  • the liquid phase material for the microcomponent is sprayed onto a substrate in the form of drops, with several drops of the material being present in a common plane and / or in different planes and after solidification form the micro device.
  • the print head By means of the print head, several drops are applied to a substrate next to and / or one above the other and / or at least partially overlapping one another.
  • the method according to the invention can thus be used to produce microcomponents quickly and easily, since after the sprayed-out liquid mass has solidified, the microcomponent is already finished, so subsequent reflow processes can largely be dispensed with.
  • the method according to the invention makes it possible to produce microcomponents which have dimensions which are smaller than 5 to 10 mm. With the print head working according to the ink printing principle, it is also possible to spray drop sizes or drops with a volume such that the contour accuracy is improved compared to the known method.
  • the material for the microcomponent and preferably a liquid support material are sprayed out of at least one print head simultaneously or in succession. If support material is sprayed out before or at the same time as the material for the microcomponent, more complex designs can also be implemented for the microcomponents, since undercuts or the like can also be formed.
  • the material for the microcomponent and the support material is sprayed out from different outlet openings of a printhead.
  • a print head is used for each material to be sprayed out.
  • a support material is also applied to the substrate, provision is preferably made for the support material to be removed after the microcomponent has been finished, so that the microcomponent is exposed.

  • the microcomponent is post-treated, for example by being subjected to a heat treatment and / or a treatment with a chemical.
  • the properties of the component surface can thus be influenced in particular.
  • the chemical can be liquid.
  • gaseous chemicals can also be used for the treatment of the micro component.
  • This object is also achieved by using a printhead which works on the ink printing principle, as stated in claim 8. It is envisaged that the printhead, which works on the ink printing principle, is used for the production of a micro component.
  • the material for the microcomponent is sprayed drop-shaped from the print head onto a substrate, wherein individual drops can be present in a common plane and / or in different planes. Drops can thus be sprayed onto one another, next to one another or at least partially overlapping. If materials are used for the microcomponent that have melting temperatures that are below 150 ° C., even printheads that do not have to be particularly temperature-resistant can be used.
  • a device for producing a micro component which shows the features of claim 9.
  • a device is therefore provided which comprises at least one printhead which works on the ink printing principle and from which the material for the microcomponent is sprayed in drops onto a substrate.
  • the print head comprises a medium chamber, a membrane forming a wall of the medium chamber and an actuator for deflecting the membrane, the medium chamber having at least one ejection opening.
  • the actuator is thermally decoupled from the membrane.
  • materials for the microcomponents that have melting temperatures that are above 150 ° C. If, for example, piezoelectric actuators are used, it is necessary to keep the operating temperature of the actuator below the piezoelectric Curie temperature.
  • thermal decoupling is provided so that the temperature on the membrane cannot be passed on to the actuator.
  • Figure 1 is a sectional view of a micro device
  • Figure 2 shows a print head
  • a microcomponent 1 is described with reference to FIG. 1, which has a relatively simple structure, here essentially T-shaped. NATURALLY Micro components with more complex or simpler structures can also be manufactured.
  • the microcomponent 1 is constructed from a plurality of layers 2, each layer preferably having a plurality of material drops 3 which lie next to one another or even partially run into one another. It is also possible that the drops 3 can be arranged partially overlapping and offset from one another within the layer, that is to say in one plane.
  • the lowermost layer 2 is sprayed onto a substrate 4 by means of a print head which works according to the ink printing principle and is shown in FIG. 2. After completion of the first layer, the second layer 2 is sprayed onto the first layer or the lowest layer 2. It can thus be seen that a plurality of material drops 3 can be present in a common plane, that is to say in a common layer 2 and / or in different planes, that is to say in different, parallel layers 2.

  • the medium chamber 10 has an ejection opening 11, from which the material drops 3 or the support material 7 are sprayed onto the substrate 4 in drops.
  • a Wall of the medium chamber forming membrane 12 is deflected so that the materials emerge in a drop shape from the ejection opening 11.
  • the print head 9 has an actuator 13, which is designed in particular as a piezoelectric element and has two contact surfaces for its electrical control, only the contact surface 14 being shown in FIG. 2.

  • the electrical actuation of the actuator 13 changes its length, so that the membrane 12 either moves in the direction of the bottom 16 of the medium chamber or is removed from the bottom 16, the membrane 12 being deflected arched. If hot materials are sprayed out of the medium chamber 10, the actuator 13 has a heat blocking element 17, which forms a thermal transition resistance between the membrane 12 and the actuator 13. This ensures that the piezoelectrically active parts of the actuator 13 are below the piezoelectric Curie temperature, so that it is ensured that the actuator 13 works optimally, that is, its change in length as a function of the applied electrical voltage remains constant, whereby constant from the ejection opening 11 Drop volume can be applied.

  • the print head 9 preferably has a heating device 19, so that the material present in the medium chamber 10 can be kept at the appropriate temperature at which it is liquid.
