Additive manufacturing or layered manufacturing is one of the most disruptive technologies in modern production. It is a process where parts are created by adding material layer by layer using a digital design, rather than cutting material away from a solid block. This is why it is often associated with additive manufacturing 3D printing and 3D additive manufacturing.
Today, additive manufacturing industry is transforming aerospace, automotive, healthcare, construction, and even consumer products. From lightweight aircraft components to customized medical implants, 3D printing and additive manufacturing services are redefining how things are designed and produced.
What is Additive Manufacturing and How Does It Work?
Additive manufacturing is a modern production process where objects are built layer by layer from a digital design. Unlike traditional manufacturing, which removes material (subtractive manufacturing), additive manufacturing adds material only where needed, allowing for complex shapes, lightweight parts, and customized designs. If you’re wondering what’s additive manufacturing and how does it work, the process follows these key steps:
Digital Design Creation
A CAD design model is created using additive design and manufacturing principles.
Additive Manufacturing File Preparation
The design is converted into an additive manufacturing file format (commonly STL or AMF), which guides the printer.
Layer-by-Layer Fabrication
The layered manufacturing process builds the part layer by layer using selected materials.
Post-Processing
Finishing steps such as heat treatment, polishing, or surface coating are applied.
This approach allows the creation of complex geometries that are impossible with traditional manufacturing.
Additive Manufacturing Technologies
Fused Deposition Modeling (FDM)
FDM also known as fused deposition modeling additive manufacturing, this technique extrudes thermoplastic material layer by layer. It’s widely used due to affordability and speed.
Additive Manufacturing Laser Sintering
Laser-based processes fuse powdered materials using high-energy lasers, enabling high-strength components.
Metal Additive Manufacturing
Metal additive manufacturing uses metal powders to produce durable, end-use parts. It is commonly used in aerospace, automotive, and industrial tooling.
Additive Manufacturing Materials
Modern additive manufacturing materials include:
Metals (Steel, Titanium, additive manufacturing aluminium)
Composites
Bio-compatible materials for medical use
The flexibility in material selection makes layered manufacturing suitable for diverse applications.
