The 7 Most Important Things to Know Before Using PVA FilamentKen Lambert (SEO)
Thanks to the advanced technology, people can now create three dimensional objects using 3D printers. It has helped people from various walks of life to create objects that were impossible to create before. From creative projects to selling items online, 3D printing has made things possible for people. It has given unique way to peopleto create unique objects and sell them.
The one thing that makes 3D printing possible is the filament. Filaments are like the raw materials that are used for creating 3D objects. There are many types of 3D printing filaments and one of them is the PVA filament. It is more of a support filament than anything else, nevertheless it is an important component in 3D printing. Using the right filament and in the right way is important for getting the desired results. Using the PVA filament can help you get the right results.
Here are the 7 most important things you need to know before using the PVA filament:
1. What is 3D Printing
If you are new to 3D printing, you probably want to know in technical terms what it is. It is a process of creating 3-dimensional solid objects of a digital design. You can use 3D printing software to create and print high-quality 3D objects using filaments. In the 3D printing process, the filament material is used to lay down several layers after it is melted to create an object. These layers are thin and look like a thinly sliced horizontal cross-section of the resulting object. 3D printing is one of the best ways to create different objects as compared to conventional manufacturing methods. It is much faster and uses less materials. All you need is a good 3D printer and the right filament to go with it. In few easy steps you can create objects for your various needs.
In 3D printing process, the PVA filament is used with other filaments like the PLA as a support material. Some objects need support while printing as they could fall or break off before they dry. Letters like T, or objects that are hanging and have hallow designs need support an the PVA filament is the best option.
2. What is PVA Filament?
PVA the PolyVinyl Alcohol, is a 3D printing filament. It is a soft, biodegradable polymer and water-soluble material. It is also known as the PVAL of PVOH. It is made by the process of polymerization of vinyl acetate to form polyvinyl acetate, which is then hydrolyzed to create the PVA filament.
The PVA material can easily dissolve in water, which makes it the perfect option as a support material. After the object is created it can be put in water where the PVA will dissolve, leaving a clear 3D object in desired design.
PVA filament is very useful for creating complex shapes especially the one with partially enclosed cavities. The PVA filament support can be easily removed by dissolving the object in warm water.
3. Why use PVA Filament
There are many advantages of using the PVA filament. The primary advantage is that is water-soluble, which makes it easy to use and remove. You can use them to make prototype model before making the actual object.
The PVA filament is also biodegradable and sustainable material for 3D printing. It is a non-toxic material without any oil content in it. Unlike other filaments, the PVA filament is one of the most user-friendly material to work with. They are great for creating testing object as you can easily dissolve them and not worry about space for extra objects.
It does not require additional solvent, which saves time and money. And, PVA does not need any additional hardware too. You can say that PVA is a hassle-free material to work with when you want to create 3D objects.
4. When not to use PVA Filament
There is no doubt that the PVA is a great support material and as well as protype 3D printing material. But it cannot be used all the time. It all depends on your 3D printing and storage needs. For instance, the PVA filament is great for prototyping, but they are not great for creating object you want to last for a long time. As soon as it comes in contact with water or moisture, it will dissolve or lose some of its character. If you have storage issues, the PVA filament should no be used as it can dissolve in water, humidity, moisture, and high temperature.
PVA has a low melting point of 190°C and in high temperature of 200 degree centigrade, it will start pyrolysis and form a jam like structure while printing. You should not use it for 3D printing for objects that require high-temperature.
5. 3D Printing Setting using PVA Filament
It is important to use the PVA filament wisely so that you can get the best results. First you need a printer that offers dual extrusion. It is important to have the right 3D printer for using PVA filament 1.75. Never use PVA along unless you want the 3D object for few hours of not for long. Use PLA filament along with the PVA as they both have very similar printing temperature. Choose printing objects that have intricate designs, or parts that have internal cavities.
Temperature setting is the most important part of 3D printing irrespective of what material you use. Likewise, correct temperature setting for the PVA filament is very important as it can dissolve and become a lump in high temperature. Depending on the brand you are using, the temperature setting can change. Some may work at 180 degrees centigrade while some may work in higher temperature.
The PVA filament needs carful storing as it is very venerable to moisture and high temperature. Make sure you store them in places where it can remain dry. Store them in airtight containers with silica at room temperature. Proper storage will ensure that the PVA material last for a long time. It is very useful for making objects that are not required to last for long such as laundry detergent tags.
7. Dry PVA Filament
It is important to first dry the PVA filament before using it. PVA filament can easily absorb water and dissolve quickly. It can easily absorb water from the air. You have to be very careful when using the PVA filament. You can keep it dry with the help of the desiccant and use it for storing as well. If you don’t store the PVA filament properly, it will not help in providing high-quality print. Dry the filament well before using it so that you can enjoy the 3D printing results.
The PVA filament is one of the best ways to print 3D objects that have internal cavities or intricate designs. They work best when they are used as support material for printing as they are water-soluble. Its high flexibility and ease of use make the PVA filament one of the best materials for 3D printing.
