PVA (Polyvinyl Alcohol) is a unique 3D printing filament known for its water-soluble properties, making it an excellent support material.
Ideal for complex prints with overhangs or intricate details, PVA provides strong support during printing and easily dissolves in
water, leaving a clean finish. It prints at a temperature range of 190°C to 220°C and is compatible with various materials like
PLA and ABS. PVA is environmentally friendly and non-toxic, making it safe to use. Its ability to provide seamless support and
easy removal makes PVA a popular choice for multi-material and intricate 3D printing projects.
As stated from the name, PVA is a synthetic polymer that is water-soluble, making it distinct from other filaments. Chemically, PVA is composed of repeating units of vinyl alcohol. It is produced through the hydrolysis of polyvinyl acetate, which converts the acetate groups into alcohol groups. This structure gives PVA its unique properties, such as its ability to dissolve in water, making it an excellent support material in 3D printing. When used in dual-extrusion printers, PVA supports can be easily removed by simply dissolving them in water, leaving behind clean and intricate prints.
