Method and Device for the Additive Manufacture of a Component, and Component Manufactured in Accordance with the Method

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method and device for additive manufacturing (3D printing) of components using powders that are electrostatically charged with either positive or negative polarity. A special application unit receives and applies the charged powder in layers, with the polarity alternating to minimize unwanted charge buildup. This technique allows for precise and efficient deposition of powder layers, supports multi-material printing (combining different materials in one part), and leads to parts with higher density and better mechanical properties.

Use CasesContent extracted from patent full text and abstract with AI.

• Industrial production of complex multi-material components with varying mechanical or thermal properties.
• Rapid prototyping and manufacturing of custom parts using advanced polymers, metals, or ceramics.
• Production of lightweight, dense, and strong parts for aerospace, automotive, or medical applications.
• Manufacturing electronic devices with integrated conductive and insulating regions in a single print process.
• Fabrication of customized implants or prostheses with tuned porosity and density in healthcare.

BenefitsContent extracted from patent full text and abstract with AI.

• Reduces charge accumulation during powder deposition, avoiding defects and improving powder layer quality.
• Enables printing of multi-material parts with strong, integral joining and locally tunable properties.
• Increases density and reduces porosity of printed parts, improving mechanical strength and performance.
• Allows precise, contactless powder placement, minimizing contamination and wear of machinery.
• Reduces material consumption and process time compared to conventional layering methods.
• Enables efficient use of commercial powders and a wide range of materials (polymers, metals, ceramics).

Patent Abstract

The invention relates to a method and a device for the additive manufacture of a component. At least one powder (P2) is provided. A plurality of component layers (B1, B2, B3) of the component to be manufactured are produced, wherein for manufacturing a component layer (B3) at least one powder fraction (A3) of the at least one powder (P2) is applied by electrostatically charging the powder fraction (A3), wherein an application unit (7) is electrostatically charged at least in some regions and the electrostatically charged powder fraction (A3) is received by means of the application unit (7), which has been electrostatically charged at least in some regions, and is transferred to an application surface (F). Various powder fractions (A3), which are to be applied for producing the component layers (B1, B2, B3), are electrostatically charged with a different polarity.
