Additive manufacturing
Additive manufacturing, also known as 3D printing, is a production method where three-dimensional objects are built layer by layer. In recent years, this technology has gained significant importance and is revolutionising numerous industries by enabling the efficient creation of complex geometries and customised products.
Characteristics and benefits
-
Complex geometries: Enables the creation of shapes that are difficult or impossible to produce with traditional methods.
-
Material efficiency: Material is only deposited where needed, minimising waste.
-
Customisation: Allows production of tailored products and prototypes designed for specific needs.
-
Reduced lead times: Products can go from CAD design to finished part more quickly through direct layer production.
Processes in additive manufacturing
-
Fused Deposition Modeling (FDM): Thermoplastic material is extruded through a nozzle to build up layers.
-
Stereolithography (SLA): Liquid resin is cured with a UV laser to produce fine, detailed objects.
-
Selective Laser Sintering (SLS): Powder material is fused by laser to form solid parts.
-
Binder Jetting: A binder is selectively applied to powder to bind layers together.
Applications
-
Medical technology: Producing implants, prostheses, and surgical tools tailored to patients.
-
Aerospace: Manufacturing lightweight, complex components to improve aircraft and spacecraft performance.
-
Automotive industry: Prototyping and production of specialised auto parts and tooling.
-
Fashion and art: Creating unique designs and artworks beyond traditional manufacturing.
Safety and environmental aspects
Additive manufacturing offers ecological advantages such as minimal material waste and local production, reducing transport. Safety aspects include proper handling of materials and machinery, as well as protective measures against emissions and particles.
Conclusion
Additive manufacturing is a forward‑looking technology transforming product design and production. Its versatility and efficiency bring significant benefits to industries from medical technology to aerospace.
