摘要：
A method for manufacturing a 3D item (10) comprising an electronic component (40), wherein the method comprises the step of printing with a fused deposition modeling (FDM) 3D printer (500) 3D printable material (201) to provide said 3D item (10), wherein the 3D printable material (201) comprises said electronic component (40). The fused deposition modeling (FDM) 3D printer comprises a printer nozzle, and the method further comprises the steps of providing upstream of the printer nozzle a filament of 3D printable material, wherein the filament comprises a cavity for hosting the electronic component, and creating upstream of the printer nozzle an assembly of the filament and the electronic component.
技术问题语段：
The patent text describes a method of 3D printing using inputs that have separate layers or sections. These inputs can be made by combining materials in a special way during the printing process. The technique allows for smaller layer sizes, different layer configurations, and the use of materials that would be otherwise difficult. The technical problem being addressed is how to make inputs for 3D printing that enable layering of different materials simultaneously.
技术功效语段：
FDM printers are fast, low-cost printers that can print complicated 3D objects. However, including electronic components in the printed object can complicate the production process. This is because the printed object may have to leave the printing stage to have the electronic component added. Conductive polymers can be used for electrical connections, but this can complicate the printing process and make it expensive for high conductivity. One solution is to use a non-circular printer nozzle or a rotatable printer head to help orient the electronic component.
