Dissolvable Supports Dissolvable supports are a type of support structure printed with water-soluble or chemical-soluble filaments, such as PVA (Polyvinyl Alcohol) or HIPS (High Impact Polystyrene). These supports are used in dual-extrusion 3D printers, where one nozzle prints the model and the other prints the support material. After printing, the supports can be dissolved in water or a specific solvent, leaving the model with clean surfaces and intricate details intact. Dissolvable supports are particularly beneficial for printing complex geometries, internal cavities, or overhangs that would be difficult to remove manually. While they increase material costs, their convenience and precision make them popular for professional and engineering applications. |
