Filament comes in two different varieties: thermoplastic and thermoset. The thermoplastic filament is melted down and then re-solidified after extrusion, while a chemical reaction hardens thermoset filamentation during the printing process. Let's take a closer look at each type of filament!
It is one of the most popular types of filaments on the market. It has a low melting temperature, which makes it easier to use than other filaments, and produces a smooth finish. PLA is also biodegradable, making it an environmentally friendly choice for 3D printing projects. The downside to PLA is that it is brittle and can break easily, so it is not ideal for parts that require strength or durability.
PLA (Polylactic Acid) is a biodegradable plastic made from renewable resources like corn starch and sugarcane. The excellent layer adhesion makes it stick to itself very well and produces high-quality prints. It also has low shrinkage and warping, which makes it ideal for higher-resolution prints. On the downside, PLA can be brittle and cannot withstand high temperatures.
PLA is easy to work with and produces strong parts with good detail and minor warping. It can also be used in a wide range of temperatures, making it one of the most versatile filaments available.
ABS (Acrylonitrile Butadiene Styrene) is a durable 3D printing filament that has been used for decades. It's more resistant to heat than PLA, making it an excellent choice for functional parts and objects. ABS is also more malleable, allowing for easier post-processing, like sanding and painting. However, it is more prone to warping and shrinkage than PLA.
Because of its heat-resistant property, it is often used in engineering applications. It has excellent strength and stability, making it great for parts that need to be durable over time. ABS requires a higher temperature to melt than PLA. Because of this, it can be more challenging. It is also not biodegradable and may release toxic fumes when heated.
ABS is durable and robust, making it great for complex designs that require strength and stability. ABS also has a low melting temperature, requiring less power to print.
It is a solid yet flexible filament that combines the excellent strength of ABS with the flexibility and ease of use of PLA. PETG retains its shape well over time and has good chemical resistance, making it an ideal choice for applications involving exposure to harsh chemicals or extreme temperatures. It does not require heating as high as ABS, so it is relatively easy to print.
It is a hybrid filament that combines the strengths of both PLA and ABS. It's incredibly strong, with excellent layer adhesion, low shrinkage, and high-temperature resistance. It also doesn't emit as harmful fumes when heated, making it safer than other filaments. On the downside, PETG can be challenging to print due to its semi-flexible nature.
PETG, or Polyethylene terephthalate glycol-modified, is known for its strength and durability. It has a high melting point and is more resistant to heat than other filaments. This makes it great for parts that require high temperatures or need to be left outside in hot climates.
It is a versatile filament option that offers both strength and flexibility. It has excellent durability and impact resistance, making it a great choice for parts that need to withstand wear and tear.
Nylon is also resistant to chemicals, making it an ideal material for components in medical applications. The downside is that nylon can be challenging to print with, as it tends to shrink and warp when heated.
Nylon can also be dyed easily to create custom colors with the proper dyeing techniques. Unfortunately, it isn't as heat-resistant as other filaments and can be prone to warping.
Filaments such asNinjaFlex, FilaFlex, and SemiFlex are great for creating parts with lots of movement.
These materials are softer than standard PLA or ABS and can make flexible parts that bend instead of cracking like traditional materials.
Filaments such as Ladywood and LayBrick are great for creating parts with a realistic wood-like texture and feel.
These filaments are made with real wood particles, so they have a more natural feel than standard PLA or ABS materials. They can also be dyed to create unique colors and finishes.
Filaments such as CopperFill and IronFill are perfect for making parts with a metallic look and feel.
These filaments are made with real metal powders much heavier than standard PLA or ABS materials. They can be used to create unique pieces that have an authentic metal finish.
No matter what type of filament you choose, it's essential to understand its properties to get the best possible outcome from your 3D printing project. With the right choice of filament, you can create amazing 3D prints that are both functional and aesthetically pleasing!
Concluding everything, the thermoplastic filament is the most popular type of filament, and it includes materials such as ABS (Acrylonitrile Butadiene Styrene), PLA (Polylactic Acid), PETG (Polyethylene Terephthalate Glycol-Modified), and nylon.
ABS is a hard plastic often used in the production of toys, while PLA is derived from renewable resources such as cornstarch and sugarcane.
PETG is a strong plastic with excellent impact resistance, making it ideal for use in items that must go through harsh conditions, such as outdoor environments or high temperatures.
Nylon is an incredibly versatile material, often used for its strength and flexibility.
Thermoset filament is the second most popular option and includes polyurethane, epoxy, and silicone. Polyurethane is a rubbery material often used for its flexibility; it can be used to make items that need to bend or conform to shapes.
Epoxy is a strong and rigid material, often used for things that need to be highly durable. Finally, silicone is great for creating flexible parts such as gaskets, seals, and more.
With the proper knowledge and resources, 3D printing can open up a world of possibilities! These are just a few of the many different types of filament available today. Each type has its benefits and drawbacks, so do your research before choosing the right one for your project.
