PVA, also known as Polyvinyl alcohol, is an incredible thermoplastic 3D printing material. PVA is used as supportive material along with PC, ABS and PLA to obtain high resolution 3D models. PVA provides its use in a wide variety of applications. Its exceptional quality to be able to dissolve in water at once makes it more convenient plastic to use. It acts as support material for designing complicated structures. It is printed using dual extrusion. It has the ability to prototype intricate designs with overhangs and cavities.
In general, PVA is used as a binding agent and supportive material in applications where plastic needs to be dissolved. It is optimal for prototyping and printing complex geometries. It aids in assembling and building large overhangs, bridges, deep internal cavities, and intricate structures. With PVA as support material, prototypes including spinners, spools/spindles can be printed instantly without the need of post-printing assembly.
Due to its thermal stability, PVA is more resistant to degradation. This offers greater possibility in generating high quality print for longer duration. After the print is finished, the created model can be immersed in water and the PVA dissolves. There is no requirement of using harmful chemicals as the material completely dissolves in the normal water. PVA is completely eco-friendly.
Owing to its solubility, PVA has a large variety of applications. It is used as an adherent, thickening agent, coolant, plastic foils and sheets. It is also used in strengthening rubber hoses, rollers, tubes etc., With PVA , one can create complex, detailed, aesthetically appealing design structures. PVA is intended to create structures that have interface layers, deep crevices and convoluted designs. Most of the PVA applications include décor items, functional prototypes, removable props and rafts.
Therefore, PVA support allows designers, manufacturers and engineers to advance towards new perspectives in a completely new way.
Both individuals and enterprises have the option to choose from a wide range of 3D printers. The 3D printers can be broadly divided into two categories – single-material 3D printers and multi-material 3D printers. Unlike single-material 3D printers, multi-material 3D printers contain multiple nozzles. Each of these nozzles deposits a single and specific material into …
