What is LSAM?
Lets first get to the essence: what is Large Scale Additive Manufacturing (LSAM)? The definition can be broken down into multiple concepts. In short: Large Scale Additive Manufacturing (LSAM) relates to the use of large industrial 3D printers that are used to create workpieces by polymer extrusion. There is no difference between LSAM, LFAM or large scale 3D printing, only the name is distinct.
Let’s get deeper into the definition of LSAM. The first part of the term, Large Scale, relates to both the large format of the 3D printer as well as the size of the printed objects. This means that large printers are able to print large workpieces. Examples of these workpieces are automotive molds and even 3D printed bridges.
The final section of the term, Additive Manufacturing, refers to the process of constructing workpieces layer by layer. 3D printing is an example of additive manufacturing. During additive manufacturing, polymer is extruded on top of a previous layer of polymer, resulting in layered structures. The opposite of additive manufacturing is subtractive manufacturing.
What are the different types of LSAM?
Large Scale Additive Manufacturing does not have a ‘one-size-fits-all’ approach. CEAD has, for example, different lines of LSAM solutions for industrial 3D printing. These solutions can be divided into robot based, gantry based and technology components, such as robot extruders. The solutions match the needs of industrial applications and therefore differ between them.
When deciding between a robot based system or a gantry based printing system, all of the factors that will influence the printing system have to be taken into account. The best solution for large scale 3D printing thus depends on the application itself.
