Introduction
As 3D printed parts are built layer by layer a previous layer to build upon is required. Depending on the specific 3D printing technology and the complexity of the 3D model, this can mean that a 3D print requires support structures.
When considering what technology to print a 3D model with it is important to consider support structures and how they may affect the final result. Supports structures will have an impact on surface finish as they require post-processing work to remove resulting in blemishes or surface roughness.
This article discusses supports, how supports are implemented for each 3D printing technology and how the use of supports can impact the design decision making process.
