This versatile material comes in various types, each possessing unique properties suitable for diverse applications. Understanding these differences is key to achieving optimal 3D printing results and exploring the possibilities of additive manufacturing.

1. What Exactly Is 3D Printer Filament?

3D printer filament is a continuous strand of thermoplastic material used in Fused Filament Fabrication (FFF) 3D printers to create three-dimensional objects. Essentially, it’s the “ink” for your 3D printer.

Think of it like the ink in a traditional printer, but instead of depositing ink on paper, a 3D printer melts and extrudes the filament layer by layer to build up a three-dimensional object. These filaments are typically available on spools and come in a variety of materials, each with its own unique properties, colors, and applications. According to a report by Grand View Research, the global 3D printing filament market size was valued at USD 1.32 billion in 2023 and is expected to grow at a compound annual growth rate (CAGR) of 21.5% from 2024 to 2030, highlighting its increasing importance in manufacturing and prototyping.

1.1. What Materials Are Used to Make 3D Printer Filament?

3D printer filaments are made from a variety of thermoplastic materials, each offering different properties and suitable for different applications. Here’s a breakdown:

PLA (Polylactic Acid): A biodegradable thermoplastic derived from renewable resources like corn starch or sugarcane. It’s known for its ease of use, low printing temperature, and minimal warping.
ABS (Acrylonitrile Butadiene Styrene): A strong and durable thermoplastic commonly used in various industries. It offers good impact resistance and heat resistance but requires higher printing temperatures.
PETG (Polyethylene Terephthalate Glycol-modified): A versatile thermoplastic that combines the strength of ABS with the ease of printing of PLA. It offers good chemical resistance, durability, and flexibility.
TPU (Thermoplastic Polyurethane): A flexible and elastic thermoplastic that can be stretched and bent without breaking. It’s commonly used for printing flexible parts like phone cases, gaskets, and seals.
Nylon (Polyamide): A strong, durable, and heat-resistant thermoplastic with good chemical resistance. It’s often used for printing functional parts like gears, bearings, and hinges.
PC (Polycarbonate): An extremely strong and heat-resistant thermoplastic that can withstand high temperatures and impacts. It’s often used for printing parts that require high strength and durability.
Composite Filaments: These filaments are infused with other materials like carbon fiber, wood, or metal to enhance their properties. For example, carbon fiber filaments offer increased strength and stiffness, while wood filaments provide a unique aesthetic appearance.

1.2. What Are the Standard Filament Sizes?

Filaments are typically manufactured in two standard diameters: 1.75 mm and 2.85 mm (often referred to as 3 mm). The 1.75 mm filament is the more popular choice due to its flexibility and compatibility with a wider range of 3D printers. The smaller diameter allows for more precise and detailed prints. The 2.85 mm filament, on the other hand, is more rigid and can provide a more consistent material flow in some printers. According to Simplify3D, 1.75mm filament is generally easier to work with and provides better resolution due to its flexibility.

1.3. How Long Does a Spool of Filament Last?

The lifespan of a spool of filament depends on several factors, including the size of the spool, the types of prints you’re creating, and the frequency of your 3D printing activities. A standard 1 kg spool of 1.75 mm filament can typically produce a significant number of small to medium-sized prints. For example, one kilogram of filament can print approximately 98 iPhone 5 cases. According to research by Pinshape, a 1kg spool can last anywhere from a few weeks to several months, depending on usage.

3D printer filament is wound onto spools for easy handling and feeding into 3D printers.

2. How Is 3D Printer Filament Used in the 3D Printing Process?

3D printer filament is the cornerstone of the Fused Filament Fabrication (FFF) 3D printing process, where it’s melted and extruded layer by layer to create three-dimensional objects. The filament is fed through a heated nozzle, which melts the plastic and deposits it onto a build platform.

The printer then precisely moves the nozzle according to a digital design, building up the object layer by layer. Once a layer is complete, the build platform lowers slightly, and the process repeats until the entire object is printed. The versatility of this process allows for the creation of complex geometries and intricate designs, making it a popular choice for prototyping, manufacturing, and hobbyist projects.

2.1. What Are the Key Steps in the Filament-Based 3D Printing Process?

The filament-based 3D printing process consists of several key steps, ensuring a precise and efficient creation of three-dimensional objects:

Design Creation: The process begins with designing a 3D model using computer-aided design (CAD) software.
Slicing: The 3D model is then sliced into thin layers using specialized software, which generates a toolpath for the printer to follow.
Filament Loading: The 3D printer filament is loaded into the printer’s extruder, which feeds the filament towards the heated nozzle.
Heating and Extrusion: The nozzle heats up to the appropriate temperature for the specific filament material, melting it into a liquid state. The printer then extrudes the molten filament through the nozzle, depositing it onto the build platform.
Layer Deposition: The printer precisely moves the nozzle along the toolpath, depositing the molten filament layer by layer, gradually building up the three-dimensional object.
Cooling and Solidification: As each layer is deposited, it cools and solidifies, bonding to the previous layer to create a cohesive structure.
Post-Processing (Optional): Once the printing process is complete, the object may undergo post-processing steps such as removing support structures, sanding, painting, or applying coatings to achieve the desired finish and functionality.

2.2. What Factors Affect the Quality of 3D Printed Objects?

Several factors can affect the quality of 3D printed objects when using filament, including:

Filament Quality: The quality of the filament itself plays a significant role in the outcome. Consistent diameter, purity, and moisture content are crucial for achieving optimal results.
Printing Temperature: The printing temperature must be carefully calibrated to match the specific filament material. Too low a temperature can result in poor layer adhesion, while too high a temperature can cause warping or deformation.
Printing Speed: The printing speed affects the layer adhesion, surface finish, and overall structural integrity of the object. Printing too quickly can lead to poor adhesion and dimensional inaccuracies.
Layer Height: The layer height determines the resolution and smoothness of the object. Lower layer heights result in finer details and smoother surfaces but increase the printing time.
Bed Adhesion: Proper bed adhesion is essential for preventing warping and ensuring that the object remains firmly attached to the build platform throughout the printing process.
Environmental Factors: Environmental factors such as temperature, humidity, and air drafts can affect the printing process and the quality of the object.

2.3. How to Store Filament Properly?

Proper filament storage is crucial for maintaining its quality and ensuring successful 3D printing outcomes. Here are some essential tips for storing your filament correctly:

Keep It Dry: Moisture is the enemy of filament. Store filament in a dry environment to prevent it from absorbing moisture from the air, which can lead to printing issues such as bubbling, stringing, and poor layer adhesion.
Use Airtight Containers: Store filament in airtight containers with desiccant packets to absorb any residual moisture.
Seal It After Use: After each use, seal the filament spool in its original packaging or in an airtight bag with a desiccant packet to prevent moisture absorption.
Control the Environment: Store filament in a cool, dry place away from direct sunlight and heat sources.
Consider a Filament Dryer: For filaments that are particularly sensitive to moisture, consider using a filament dryer to remove any absorbed moisture before printing.
