In additive manufacturing, a structure provides an enhanced foundation for the initial layer of a three-dimensional object. This foundation, typically composed of one or more layers of material, is constructed beneath the part to be printed. It acts as a disposable platform, aiding in adhesion and mitigating warping issues that can arise during the printing process.
The use of this base structure is particularly beneficial when printing with materials prone to shrinkage, such as ABS, or when the part has a small contact area with the build plate. It promotes better thermal management, distributing heat more evenly, which reduces the likelihood of deformation. Historically, its implementation stemmed from the need to improve print success rates on platforms lacking heated beds or precise leveling systems.
