PVA 3D Printing – Who Makes the Best PVA Filament

ADVERTISEMENT

PVA is one of the most popular-by-name, but lesser-explored 3D printer filaments. Like every other filament, PVA has its own distinct characteristics that separate it from the rest.

A PVA filament is known to quickly dissolve in water. And in FDM 3D printing the rarest complex geometries cannot be printed with water-soluble supports. So, whenever you’d want to print an object which has a complicated geometry, PVA’s utilization would be a must.

PVA is an abbreviation for Polyvinyl Alcohol. Chemically, it is a synthetic polymer that is made by polymerizing vinyl acetate and hydrolyzing the product.

Although not as much as it is used for making support structures, PVA can be utilized independently to make parts and functional prototypes as well. Also, the material is completely sustainable. It is non-toxic in nature and biodegradable thereby not harming the environment at all.

PVA filaments are hygroscopic in nature, therefore they absorb moisture from the air easily. So, you need to take care while storing the filament. If you do not store it in an air-tight container, the filament will start absorbing air and will end up forming bubbles on the final 3D printed part, thereby leading to a part failure.

Because of relatively less knowledge about PVA filament, it is hard to decide which brand is better than the other. And so, often users end up buying a brand that’s not reliable.

The other times it’s also their fault because they just buy it without reading its specifications: what extruder/print bed temperature range it needs for 3D printing.

To ensure none of that happens, we have come up with some of the best brands that are currently manufacturing reliable PVA filaments in the market. So, let’s go through them one after the other.

The Conclusion

Choosing one from the above-mentioned seven is not an easy task at all. All of them have a minute variance from the other one and this micromanagement is only possible by matching your part requirement with PVA filament’s buying guide.

Typically things to look at within PVA filament are Strength, Flexibility, Durability, Print temperature, bed temperature, and its compatibility with various materials.

More than anything one must check out how quickly the filament melts in water because that’s what it does mainly. PVA filament becomes a support structure to 3D printing materials such as PLA and ABS and even rare ones.

No material but PVA assists in the creation of intricate designs and internal cavities. By acting as a support material for the user’s design, the filament provides great flexibility.

PVA filament easily pairs with a dual extrusion FDM 3D printer, unlike HIPS 3D printer filament. Also, chiefly it works the most of all with PLA material. It is advised to keep lower temperatures for doing the right print settings.

The filament is completely biodegradable and hence environment-friendly which also makes it separate from the much popular ABS and PLA.

Having stated all of that, you must take immense care of storing the filament in the correct space wherein there is absolutely no scope for air. Because PVA is hygroscopic in nature and will form bubbles and lead to part failure, in case proper care is not taken.
