From simple toys to complex automotive components, 3D printing is used to create a diverse range of products. It’s called “3D printing” because it builds three-dimensional objects by printing them. Rather than ink, of course, 3D printers use raw material. Robocasting is a unique form of 3D printing, however, that’s commonly used in the manufacturing industry. What is robocasting in 3D printing exactly, and how does it differ from other forms of 3D printing?
Overview of Robocasting
Also known as robotic material extrusion, robocasting is a 3D printing process that works in a similar way as fused filament fabrication (FFF). It involves the use of a 3D printer that extrudes raw material out of a print head, resulting in the production of an object. The robocasting 3D printer releases the material from its print head to build each layer of the object.
Robocasting still requires the use of computer-aided software (CAD). Prior to building an object with this 3D printing method, manufacturing companies must design the object in CAD software. Once the object has been designed, the CAD file is uploaded to the robocasting for building. The 3D robocasting 3D printer will then take build the object using the specifications included in the CAD file.
How Robocasting Differs From FFF
Considering that both robocasting and FFF build objects by depositing layers of material onto a bed, you may assume they are the same. The difference between them is that robocasting doesn’t require additional time to dry or solidify after being deposited, whereas FFF does.
With FFF, the raw material is heated and then released from the 3D printer’s nozzle. The material must then be allowed to cool so that it can dry while taking the appropriate shape. Robocasting differs in the sense that it doesn’t require additional time to dry and solidity. Once the robocasting 3D printer has extruded the raw material from its nozzle, the material will preserve its shape.
Benefits of Robocasting
Robocasting offers several benefits, one of which is the ability to build fragile or otherwise delicate objects without breaking them. Robocasting 3D printers can carefully extrude the material in a way that won’t damage it or the object. As a result, it’s commonly used to build fragile or delicate objects.
Robocasting also support objects with large surface area. It’s not limited to small objects with a limited amount of surface area. Rather, robocasting supports all types of objects, including those with a large amount of surface area.
