What Are the Most Popular 3D Printer Filament Types and Materials?

3D printing filament is typically the thermoplastic feed stock for fused filament 3D printers.3d printer filament There are several types of filament on the market with varying properties, needing different temperatures for optimal printing. The most common thermoplastic is Type D, which perform best with the heated bed method, and also needs minimal support. Types A, B and C can be used in both the heated-and-cool method.

Depending on your requirements, you may opt for polycarbonate or solid polystyrene (aka polystyrene), or polyimide, which is a type of polymer composed of millions of tiny crystalline molecules fused together to form strands.3d printer filament 3d printer filament In addition, there are several thermoplastics, including nonglass, nylon and polycarbonate. The most common uses of the filament are for rapid prototyping, large format printing and fine coating applications.

Polyimide has a low melting temperature and high stiffness, and hence it tends to shrink when heated, making it unsuitable for solid materials.3d printer filament Polyacrylics, also known as polylactic acid, is also popular for fast production. It combines high heat resistance with excellent adhesive ability. It's also easy to clean, although it tends to produce small amounts of waste during the printing process. This is a popular choice for applications requiring tight filaments due to its high melting temperature.

All three of the most popular types of thermoplastics have a slightly different physical structure, but are usually available in a standardised version. They are more resistant to abrasion and therefore provide a better surface texture than their polyamides counterpart. This means that the quality of the finished object will be higher. The cost per filament is also generally lower for all three types.

A popular alternative to the above materials is polyurethane, which has similar advantages. It's widely used in applications requiring high surface tension, such as with computer drives and cartridges. This is because it provides a smooth surface and extremely high adhesion properties. It also provides the benefit of a rigid structure, which means that it can be machined with greater ease than most thermoplastics and polymers. Unfortunately, the high cost associated with this type of 3d printer filament means that it is rarely used in home printers.

When using a hot roll method to extrude plastics, you are likely to encounter two different thermoplastics. These are polycarbonate and nylon, which have lower melting temperatures. The difference between the two is that nylon exhibits a greater degree of plastic shrinkage when heated, which gives it a more consistent extrusion pattern. Nylon also rolls much smoother than polycarbonate. Due to its plastic-like qualities, nylon typically comes in a wider range of colors, although the only colors available currently are black, blue, green, white, pink, and gray. Polycarbonate on the other hand, is typically only available in black, blue, and gray, which limits the printing options offered by many manufacturers.
