Abstract
The invention relates to a method for producing three-dimensional models by means of a layering technique, particulate build material being applied to a build space in a layer, and a binder fluid then being selectively applied to the build material, proceeding in layers, and these steps being repeated until the desired model is produced, a controlled air flow being conducted through the applied build material, as well as a device for carrying out the method and thus produced models.
Claims22
A method for producing three-dimensional models by means of a layering technique, comprising the steps of:
- applying a particulate build material in a layer onto a build space, and then selectively applying a binder fluid to the particulate build material, and repeating these steps until a desired model is produced layer by layer,
- wherein the method includes a controlled air flow being conducted through the applied particulate build material after the desired model is produced layer by layer;
- wherein the binder fluid has a boiling point below a boiling point of distilled water.
A method for producing three-dimensional models by means of a layering technique, comprising steps of:
- applying a particulate build material in a layer onto a build space, and then selectively applying a binder fluid to the particulate build material, and repeating these steps until a desired model is produced layer by layer,
- wherein the method includes a controlled air flow being conducted through the applied particulate build material;
- and
- wherein the method includes a step of forming one or more ventilation bodies or one or more air channels in the applied particulate build material.
A method for producing three-dimensional models by means of a layering technique, comprising the steps of:
- applying a particulate build material in a layer onto a build space, and then selectively applying a binder fluid to the particulate build material, and repeating these steps until a desired model is produced layer by layer,
- wherein the method includes a controlled air flow being conducted through the applied particulate build material after the desired model is produced layer by layer;
- and
- wherein a direction of the controlled air flow is changed during the method.
A device for producing three-dimensional models by means of a layering technique comprising:
- one or multiple means for producing a controlled air flow in a build material;
- wherein a flow direction of the controlled air flow is changeable during the producing of the three-dimensional models.
A method for producing three-dimensional models by means of a layering technique, comprising the steps of:
- applying a particulate build material in a layer onto a build space, and then selectively applying a binder fluid to the particulate build material, and repeating these steps until a desired model is produced layer by layer,
- wherein the method includes a controlled air flow being conducted through the applied particulate build material after the desired model is produced layer by layer;
- and
- wherein the controlled air flow flows through the build material via a plate placed on the build material.
A device for producing three-dimensional models by means of a layering technique comprising:
- one or multiple means for producing a controlled air flow in a build material;
- wherein the build material is in contact via a plate provided with an air flow means and placed on the build material.
