Comparison of Top 3D Printer Filaments

PLA Filament

One of the most popular types of 3D printer filaments is PLA (polylactic acid). PLA filament is made from renewable resources such as cornstarch or sugarcane, making it an environmentally friendly option. It is also known for its ease of use and versatility. PLA is biodegradable and does not emit hazardous fumes during printing, making it a safe choice for home use. To broaden your knowledge of the topic, we recommend visiting this carefully selected external website., uncover supplementary details and intriguing perspectives on the topic.

PLA filament is ideal for producing detailed and intricate models. It has a low melting point, which means it requires less heat during the printing process. This makes it compatible with a wide range of 3D printers. The surface finish of PLA prints is smooth and glossy, and the filament is available in a wide array of colors.

However, PLA does have some limitations. It is not as strong or durable as some other filaments, which may make it unsuitable for certain functional parts. It can deform or soften under high temperatures, so it is not recommended for applications that will be exposed to heat. Additionally, PLA can be brittle and may break under stress or impact.

ABS Filament

Another popular type of 3D printer filament is ABS (acrylonitrile butadiene styrene). ABS is a strong and durable thermoplastic that is commonly used in the manufacturing industry. It has excellent impact resistance and can withstand high temperatures, making it suitable for functional parts and prototypes.

ABS filament requires a higher printing temperature than PLA, typically between 210-250 degrees Celsius. This higher temperature can cause unpleasant fumes during printing, so it is important to have adequate ventilation. ABS also tends to warp or shrink when it cools, which can result in print distortion or detachment from the print bed. To minimize this issue, a heated print bed and an enclosed build chamber are often recommended for printing with ABS.

One of the advantages of ABS is its flexibility. It can be easily post-processed by sanding, drilling, or painting, allowing for greater customization and finishing options. However, ABS is not biodegradable and is derived from petroleum, making it less environmentally friendly compared to PLA.

PETG Filament

PETG (polyethylene terephthalate glycol-modified) is a relatively newer filament option for 3D printing. It offers a balance between the strength and durability of ABS and the ease of use and safety of PLA. PETG is known for its high impact resistance and chemical resistance, making it suitable for a variety of applications.

PETG filament is less prone to warping compared to ABS and does not require a heated print bed. It also has a higher melting point than PLA, making it suitable for functional parts that will be exposed to higher temperatures. PETG prints have a good layer adhesion and a semi-transparent appearance, which can be desirable for certain applications.

One drawback of PETG is its stringing tendency during printing. This means that the filament may leave thin strands or strings of material between printed parts. However, this issue can often be minimized through proper printer calibration and settings adjustment.


When choosing a 3D printer filament, it is important to consider the specific requirements of your project. PLA filament is a versatile and beginner-friendly option, but may not be suitable for functional parts. ABS filament offers strength and durability, but requires higher printing temperatures and can emit fumes. PETG filament provides a balance between the two, with good impact resistance and ease of use.

Ultimately, the choice of filament depends on your specific needs and preferences. It is recommended to experiment with different filaments to find the one that best suits your printing requirements.
