3D Printing Materials: Polyvinyl Alcohol (PVA)

——————————————————————
Polyvinyl Alcohol (PVA) is a type of petroleum based plastic that is water soluble.  It is biodegradable and recyclable, and non-toxic.  It can be extruded at temperatures of 190-210 deg C.  It is relatively expensive compared to materials such as PLA and ABS. Due to its ability to dissolve in water, PVA based material must be stored carefully, away from water and moisture.  For example, it can be stored in sealed bags with silica gel.  Once removed from its packaging PVA can absorb moisture.  
Since PVA is water soluble, it is used for providing support for overhanging portions of objects being 3D printed.  The 3D printer has to be capable of extruding two materials.  A PVA based structure is 3D printed before the overhang portions.  The overhang portions are 3D printed, with support from the PVA based structure.  The final 3D printed object is put in water to let the PVA based support structure dissolve.  After the PVA based support structure dissolves, what remains is the 3D printed object with overhangs.

3D  Printings world  things are made by building up multiple layers of material.

This process is environmental friendly and is relatively simple, depending on the specific project at hand.

3d has 3 companies that investors should know. Two of them have double the stocks and one of them has triple.

In California, Los Angeles has United 3D printing. Its website is listed here:
