Why is support material utilized in additive manufacturing?

Support material is utilized in additive manufacturing primarily to provide stability for overhangs and complex geometries during the printing process. When an object has features that extend out over open air, such as overhangs or intricate structures, the printer needs additional support to ensure that these features can be adequately formed without collapsing due to gravity or the weight of the material itself.

Without support material, it would be challenging to successfully print these types of designs because the molten or extruded material could sag or droop before it has time to cool and solidify. Support structures are designed to be easily removed once the print is complete, ensuring a clean finish on the main object while allowing for the successful manufacturing of complex shapes.

Thus, the function of support material is essential for achieving design freedom and maintaining print quality in additive manufacturing.
