Is additive manufacturing the same as 3D printing?
Additive Manufacturing is often referred to as 3D printing (also as AM or ALM – Additive Layering Manufacturing). Strictly speaking, there is no technical difference between AM and 3D printing, since they both add controlled layers of materials to create objects. The term Additive Manufacturing is mainly used to designate the manufacturing process in industrial applications, while 3D printing usually refers to smaller machines used at home or in artisanal applications for arts, crafts and hobby applications.
ISO (International Organization for Standardization) has categorized seven types of AM processes to improve global communication between those who work in various industries:
- VAT Photopolymerization (also known as stereolithography)
- Material Jetting
- Binder Jetting
- Material Extrusion
- Powder Bed Fusion
- Sheet Lamination
- Directed Energy Deposition
