With the natural MakerBot 1.75mm PVA Precision Support Filament 3-Pack, you'll be able to print 3D models with unique shapes.
PVA stands for polyvinyl alcohol and is specifically used as a support material. It is mainly used in conjunction with PLA, though it can also be used with other materials. PVA dissolves in water, which enables you to print complex objects. Since PVA is sensitive to moisture, you should store it in airtight containers. This filament also utilizes Smart Spool, which provides material type, color, and amount remaining information via an RFID chip to MakerBot Print. A desiccant in the spool also helps maintains a low moisture level inside the drawer bay.
