Amphora filament is a 3D printing material making waves in the 3D printing community. It is made of Amphora polymer, which is said to have a whole host of benefits over other filaments currently on the market. But what are Amphora's pros and cons? And where can you buy it?
In this blog post, we will explore Amphora filament in detail and answer all your questions!
What is Amphora polymer?
Amphora is a synthetic polymer with a wide range of potential applications. It is lightweight and durable for its resistance to heat and chemical damage. Amphora polymers are also used in various industries, including food packaging, electronics, and automotive manufacturing. The unique properties of this material make it an ideal choice for many different applications.
Let's dig a bit deeper and get a bit more technical.
Amphora polymers are copolymers that contain both hydrophilic and hydrophobic monomers. The copolymer consists of a polyethene glycol backbone with pendant groups that can be acidic or basic. Amphora polymers are commonly used as drug delivery carriers, as they can encapsulate and release a wide variety of drugs. They are also used in cosmetics and personal care products. They can help improve the stability and efficacy of active ingredients. In addition, amphora polymers are often used in coatings and adhesives, as they can enhance the adhesive properties of these products.
Amphora has a low glass transition temperature, making it less likely to break or shatter when exposed to heat. Amphora also has a high melting point, meaning that it can be used in applications where other filaments cannot. Amphora is also chemically resistant and can be used in harsh environments without fear of damage.
What are the features of Amphora filament?
Durable and Flexible:
Amphora is the ideal filament if you want a more durable print than PLA, flexible like TPU and strong as ABS. It doesn't bend as readily as TPU, but it's flexible enough to withstand much pressure. It is certainly not brittle. Thus an Amphora print will serve a functional purpose beyond looking pretty in a display case.
Finally, Amphora's layer-to-layer adhesion is superior to many other filaments.
It doesn't emit harmful fumes or noxious odours during printing.
ABS has a distinct, unpleasant smell while printing that must be dealt with by ventilating the area where you're operating. The Amphora filament is odour-free. Amphora, according to Eastman, is an entirely styrene-free product, so you may at least be confident that it contains no hazardous pollutants. The printing process with Amphora filament is relatively odourless. However, it might produce microplastics in the air, suggesting that some ventilation is still recommended.
Prints at high temperature
Amphora filament prints at the high end of the ABS printing temperatures, somewhere around 240 to 260 °C. Amphora is heat stable, which means that you can use it over a wide range of temperatures without affecting the quality of the finished product; this ensures that your 3D print retains its shape and integrity when exposed to high temperatures. The third advantage of the Amphora print is that it won't melt in warm conditions; this means you can leave your completed Amphora artwork outside on a hot day or even keep it in your car on such days without fear of it melting.
When exposed to most acids, solvents, oils, grease, and essential compounds, Amphora is resistant to degradation. Unfortunately, there are no solvent-based finishing techniques available for an Amphora print because it is chemically stable. Suppose you want your Amphora print to have a professional-grade finish. In that case, you'll have to rely on sanding and polishing techniques.
Good dimensional stability
The Amphora is an excellent printer for art. It can produce outstanding results, but there are a few things to be aware of if you want your artwork to last. Because the material heats up at a high temperature, you'll still need to take precautions against warping. It's nothing ordinary - a heated printing bed, a bed adhesion aid, and no cooling on the first layer should do the trick.
On the other hand, Amphora does not warp quite as readily as ABS. As a result, it does not require as high of a temperature setting on the heated bed. It even can turn on the cooling fan by layer 3 or 5 of printing.
Better bridging performance
Amphora's exceptional strength, combined with the ability to turn on a cooling fan in the middle of the print, makes it one of the most reliable bridging materials available. Amphora can reach as far as 15 cm without crumbling when you need to produce overhanging features. However, there is a hard limit of 15 cm before support structures should be used.
FDA-approved for food contact
Amphora is a food-grade type of concrete that has been used since ancient times. It's safe for food contact applications, as it doesn't produce any hazardous chemicals. Despite this approval, we still don't advise using any 3D printed container for long-term or repeated food storage because 3D printing (particularly with FDM) naturally creates a surface finish full of microscopic pores that could harbour bacteria.
Amphora filament is more expensive than ABS, but it's still much cheaper than some more technical filaments.
What are the pros and cons of Amphora filament?
Amphora is a lightweight and durable filament resistant to heat and chemicals, making it ideal for use in 3D printing. It has a low glass transition temperature, meaning it is less likely to break or shatter when exposed to heat, and a high melting point, meaning you can use it in applications where other filaments cannot. Amphora is also chemically resistant and can be used in harsh environments without fear of damage. However, Amphora is a new material and may not be compatible with all 3D printers. In addition, it is more expensive than some other filaments on the market. Additionally, Amphora may not be available in all regions.
