Definitions

  • the present invention relates to a device for the additive manufacturing of a three-dimensional component with the features of the preamble of claim 1.
  • the invention also relates to a method for the additive manufacturing of a three-dimensional component according to claim 9.
  • thermoplastic materials in particular thermoplastics
  • thermoplastics can be used, which are first liquefied by heating. The liquid material is then selectively applied to areas where the workpiece is to be created. The material solidifies again as it cools.
  • Such a device includes a print head in which the starting material is prepared for printing. Furthermore, axis systems for generating a relative movement between the print head and the work surface on which the object is to be created are known. Either only the print head, only the work surface or both the print head and the work surface can be moved. Some thermoplastic materials tend to shrink when cooled. The shrinkage leads to deviating dimensions of the finished workpiece. In order to counteract this, so-called 3D printers with heatable construction chambers are known, so that the temperature of the construction chamber can be kept as constant as possible during the printing process. There are elements that can protrude into the build chamber, for example, and thereby change the temperature structure.
  • thermal bridges can arise, which results in uneven temperature control of the build chamber and can lead to thermal distortion in the workpiece or component to be produced. An error-free construction of the workpiece or component to be manufactured is therefore not possible due to the thermal distortion that has occurred.
  • the object of the invention is to provide a device that makes the additive manufacturing of a three-dimensional workpiece made of a thermoplastic material more efficient and therefore more cost-effective.
  • the object is achieved by the device according to the invention for the additive manufacturing of a three-dimensional workpiece with the features of claim 1 and the method according to the invention for the additive manufacturing of a three-dimensional workpiece according to claim 9 .
  • the proposed device for the additive manufacturing of a three-dimensional workpiece comprises a construction chamber, at least one print head, a receiving device for receiving the three-dimensional workpiece, a circulating air system for tempering and conveying a gaseous fluid, an adjustment device comprising an xy-axis system with a print head mount and a z- Axis system, wherein according to the invention the air circulation system has a device for tempering and conveying a gaseous fluid, an inlet device with at least two inlet openings connected to the construction chamber and an outlet device, wherein the Outlet device is integrated into the z-axis system and is adjustable with it.
  • the device for the additive manufacturing of a three-dimensional workpiece is also known as a 3D printer or printer.
  • optimization of the temperature control of the construction chamber is achieved in an advantageous manner by the circulating air system with the device for temperature control and conveying of the gaseous fluid.
  • the device according to the invention for the additive manufacturing of a three-dimensional workpiece thus counteracts inhomogeneous temperature control of the construction chamber and ensures a more homogeneous temperature structure in the entire construction chamber.
  • the gaseous fluid can be air or advantageously an inert gas.
  • the circulating air system includes the device for tempering and conveying the gaseous fluid, which advantageously heats the gaseous fluid and conveys it into the circulating air system.
  • the gaseous fluid flows through the inlet device into the construction chamber, fills it, flows around the workpiece to be manufactured and then flows through the outlet device integrated in the z-axis system.
  • the circulating air system of the device for the additive manufacturing of a three-dimensional workpiece advantageously ensures a homogeneous temperature structure within the construction chamber.
  • the device according to the invention for the additive manufacturing of a three-dimensional workpiece combines the adjustment in the z-height of the axis with the removal of the process air for the air circulation system. Due to this modified ventilation system, the temperature of the build chamber is kept more constant together with the workpiece or component. Advantageously, the temperature control is much more uniform, resulting in less distortion in the workpiece or component.
  • the outlet device has recesses which are arranged in a housing of the z-axis system.
  • the recesses of the outlet device are arranged below the receiving device.
  • the inlet device has channels and connection devices with inlet openings, the gaseous fluid being able to be conveyed from the device for temperature control and conveying through the inlet device into the construction chamber.
  • the inlet openings of the inlet device are arranged above the workpiece and the z-axis system.
  • the inlet openings of the inlet device include valves.
  • the main advantage here is the central discharge or the central suction of the gaseous fluid or the process air below the construction chamber, which enables an air flow that results in a homogeneous temperature control and at the same time in the same assembly as the height adjustment of the receiving device for the workpiece, or the substrate carrier takes place.
  • the previously five breakthroughs in the floor of the construction chamber for example, only one breakthrough is necessary due to the design according to the invention.
  • the temperature of the telescopic axis of the z-axis is controlled and thus advantageously no longer represents a cold bridge Cables for sensors and lines, or cables for heating the building board are laid in the housing or the ventilation shaft.
  • the concentration of these functions advantageously enables a significantly more cost-effective implementation and increases the accessibility and maintainability of the build chamber. This advantageously makes it possible, for example, to pull the entire build chamber out of the printer.
  • the substrate carrier is dismantled and the z-axis or
  • Telescopic axis moves out of the build chamber.
  • the efficiency of the build chamber temperature control is improved overall, since less heat is dissipated due to the changed z-axis.
  • the placement of the inlet and outlet leads to a more even distribution of the heat introduced, which prevents cold or heat spots within the build chamber.
  • no further opening in the build chamber is necessary, which simplifies changing the build chamber in the event of maintenance.
  • the inlet openings of the inlet device are suitable for receiving interchangeable inlet molds, with the inlet molds having different geometries or different shapes depending on the geometry of the workpiece.
