Abstract
In order to improve three-dimensional (3D) printing a high-aspect-ratio three-dimensional metal structures, there is provided a printing method that builds a wall comprising a center part made out of a metal-containing material and left and right parts made out of a plastic material forming first and second supporting wall elements. The plastic support material may be used to enable the build-up of a high-aspect-ratio 3D structure. The proposed printing strategy may be applicable to a cost-effective 3D printing technology, such as fused deposition molding (FDM).
Claims13
A method for three-dimensional printing of a grid for selective transmission of electromagnetic radiation, comprising:
- a) depositing a layer of a plastic material on a substrate to form a first supporting wall element;
- b) depositing, parallel to the first supporting wall element, a layer of the plastic material on the substrate to form a second supporting wall element, wherein the second supporting wall element is distanced from the first supporting wall element to form a confined region therebetween;
- c) depositing a layer of a metal-containing material in the confined region to form a center wall element, wherein the first supporting wall element, the second supporting wall element, and the center wall element form a sandwich wall, wherein the metal-containing material comprises a mixture of metal powder in a plastic material or a mixture of metal powder in a binder material, and wherein metal-containing material is a radiation opaque material;
- and
- repeating a) to c) a selected number of times to produce a selected number of successive layers according to a predefined pattern to print the component, wherein the predefined pattern is a grid-like pattern.
An additive manufacturing apparatus, comprising:
- a material depositing system configured to a material at a target area;
- an energy source configured to melting the material;
- and
- a controller configured to control the material depositing system and the energy source for carrying out a method comprising:
- a) depositing a layer of a plastic material on a substrate to form a first supporting wall element;
- b) depositing, parallel to the first supporting wall element, a layer of the plastic material on the substrate to form a second supporting wall element, wherein the second supporting wall element is distanced from the first supporting wall element to form a confined region therebetween;
- c) depositing a layer of a metal-containing material in the confined region to form a center wall element, wherein the first supporting wall element, the second supporting wall element, and the center wall element form a sandwich wall, wherein the metal-containing material comprises a mixture of metal powder in a plastic material or a mixture of metal powder in a binder material, and wherein metal-containing material is a radiation opaque material;
- and
- repeating a) to c) a selected number of times to produce a selected number of successive layers according to a predefined pattern to print the component, wherein the predefined pattern is a grid-like pattern.
A non-transitory computer-readable medium having stored thereon executable instructions, which cause a method for three-dimensional printing of a grid for selective transmission of electromagnetic radiation to be performed, the method comprising:
- a) depositing a layer of a plastic material on a substrate to form a first supporting wall element;
- b) depositing, parallel to the first supporting wall element, a layer of the plastic material on the substrate to form a second supporting wall element, wherein the second supporting wall element is distanced from the first supporting wall element to form a confined region therebetween;
- c) depositing a layer of a metal-containing material in the confined region to form a center wall element, wherein the first supporting wall element, the second supporting wall element, and the center wall element form a sandwich wall, wherein the metal-containing material comprises a mixture of metal powder in a plastic material or a mixture of metal powder in a binder material, and wherein metal-containing material is a radiation opaque material;
- and
- repeating a) to c) a selected number of times to produce a selected number of successive layers according to a predefined pattern to print the component, wherein the predefined pattern is a grid-like pattern.
