3D printing filaments are essential materials used in the process of 3D printing. These filaments are essentially plastic materials that are melted and extruded through a 3D printer’s nozzle to create a 3D object. There are various types of 3D printing filaments available, each with its own unique properties, such as strength, flexibility, and appearance. In this article, we will discuss the top three 3D printing filaments used by professionals and hobbyists today.
The Basics of 3D Printing Filaments
3D printing has revolutionized the manufacturing industry, and with it comes the need for 3D printing filaments. These filaments are used as the raw material for 3D printing objects. They are melted and extruded through a nozzle to create the object layer by layer. The most common types of 3D printing filaments are PLA, ABS, and PETG.
PLA Filament
PLA filament is the most popular type of 3D printing filament. It is made from renewable resources such as cornstarch, sugarcane, and cassava roots. PLA is biodegradable and does not emit harmful fumes during printing. It is easy to print with and produces high-quality prints. However, PLA is not suitable for objects that will be exposed to high temperatures or UV light.
ABS Filament
ABS filament is a thermoplastic that is commonly used in 3D printing. It is durable and can withstand high temperatures, making it suitable for objects that will be exposed to heat or UV light. However, ABS emits harmful fumes during printing, so it should be used in a well-ventilated area. It is also more difficult to print with than PLA.
PETG Filament
PETG filament is a combination of PET and glycol. It is strong, flexible, and easy to print with. It is also resistant to high temperatures and UV light. PETG emits fewer fumes than ABS, making it a safer option for indoor use.
Other Types of 3D Printing Filaments
Aside from the common types of 3D printing filaments, there are also other types that are used for specific purposes.
Key takeaway: 3D printing filaments are essential for creating 3D printed objects, and there are several types of filaments available, each with its own unique properties and characteristics. When selecting a filament, it is important to consider factors such as the object’s purpose, printing difficulty, filament cost, and diameter. Additionally, common misconceptions about filaments include the belief that all filaments are the same, that they are all expensive, and that they are all harmful to the environment.
Nylon Filament
Nylon filament is strong and flexible, making it ideal for printing objects that require durability, such as gears and hinges. It is also resistant to abrasion and chemicals. However, nylon filament is more difficult to print with than PLA or ABS.
TPU Filament
TPU filament is a flexible and rubber-like material that is commonly used to print phone cases, toys, and other objects that require flexibility. It is also resistant to oils and greases. TPU filament is easy to print with and does not emit harmful fumes.
PVA Filament
PVA filament is a water-soluble material that is commonly used as support material for 3D printing. It dissolves in water, leaving the printed object intact. PVA filament is ideal for printing objects with intricate designs or overhangs that require support during printing. However, PVA filament is more expensive than other types of filaments.
Metal Filament
Metal filament is a composite filament that contains metal particles such as copper, bronze, or steel. When printed, the object has a metallic finish and weight. Metal filament is ideal for printing jewelry, figurines, and other decorative objects. However, metal filament is more expensive than other types of filaments, and it requires a specialized 3D printer with a metal extruder.
Wood Filament
Wood filament is a composite filament that contains wood particles such as bamboo or birch. When printed, the object has a wooden texture and appearance. Wood filament is ideal for printing decorative objects such as vases or bowls. However, wood filament is more difficult to print withthan other types of filaments, and it requires a specialized 3D printer with a wood extruder.
How to Choose the Right Filament for Your 3D Printing Project
Choosing the right filament for your 3D printing project can be a daunting task, especially for beginners. Here are some factors to consider when selecting a filament:
Key Takeaway: Choosing the right filament is crucial for successfully 3D printing an object. Consider factors such as object purpose, printing difficulty, filament cost, and filament diameter when selecting a filament. Additionally, each filament has its own unique properties and characteristics that make it suitable for specific purposes, so it is important to understand the differences between them.
Object Purpose
The purpose of the object you are printing should be the main factor in selecting a filament. If the object will be exposed to heat or UV light, ABS or PETG filament would be a better choice than PLA. If the object requires flexibility, TPU filament would be a better choice than PLA or ABS.
Printing Difficulty
Different filaments have different printing difficulties. PLA is the easiest filament to print with, followed by PETG and TPU. ABS and nylon are more difficult to print with and require a higher printing temperature.
Filament Cost
The cost of filaments varies depending on the type and brand. PLA is the most affordable filament, followed by PETG and ABS. Nylon, TPU, metal, and wood filaments are more expensive than other types of filaments.
Filament Diameter
The diameter of the filament is important for ensuring a smooth and consistent printing process. Most 3D printers use 1.75mm or 3mm filaments. Make sure to check the specifications of your 3D printer before purchasing a filament.
Common Misconceptions About 3D Printing Filaments
There are some common misconceptions about 3D printing filaments. Here are some of them:
All Filaments are the Same
All filaments are not the same. Each filament has its own unique properties and characteristics that make it suitable for specific purposes.
Filaments are Expensive
While some filaments such as metal and wood filaments are expensive, other types of filaments such as PLA and PETG are affordable.
3D Printing Filaments are Harmful to the Environment
Most 3D printing filaments such as PLA are made from renewable resources and are biodegradable. However, some filaments such as ABS emit harmful fumes during printing.
FAQs – What are 3D printing filaments?
What are 3D printing filaments?
3D printing filaments are the raw materials used for 3D printing. These materials are typically a type of plastic, and they come in long, thin strands that are fed into a 3D printer to create an object by melting and extruding the plastic layer by layer.
What types of materials are used for 3D printing filaments?
