What Are The Six Different 3d Printer Filament Types?
The options for consumer 3D printers go beyond ABS and PLA filaments. The increasing popularity of additive manufacturing has led to the rise of many engineering plastics. Although ABS and PLA remain popular, many 3D printing enthusiasts have shifted to newer materials.
Here's everything you must know about various 3D printing filaments and how to choose one for your particular needs.
What is the best 3D printing filament?
3D printing is a distinct activity that isn't found in the popular culture. It involves sophisticated robots that create complicated objects from exotic materials. 3D printing, just like other advanced engineering projects, depends on the ability of users to read and follow technical data sheets. Understanding the meaning of these data sheets is key in determining which 3D printing filament is best for the specific application.

There's no need to bother about this if your 3D printing requirements are limited to aesthetic prints since PLA is all you'll ever need. Printing functional parts, however, needs an understanding of various filament parameters, such as tensile strength, toughness/flexibility, heat resistance, durability, creep, and warping.
1. PLA (Polylactic Acid).
Polylactic Acid is to 3D printing the way training wheels are to bicycles. Even the most basic 3D printers can print it. You don't need an all-metal hotend to print this filament safely because the printing temperatures begin at 180°C. PLA does not even need a heated bed, as long as the ambient temperature of the room is kept at or above 20 degrees Celsius.
PLA is ideal for 3D printed cosmetic prints however it's not ideal for any other purpose. Despite its strength of tensile however, it is not as tough due to its being too hard to flex. This causes it to be brittle and prone to cracking when used in applications that require resistance to impact and bending. The low temperature printability of PLA also translate into poor heat resistance. PLA prints shrink when exposed to direct sunlight or in-car conditions due to its low glass transition temperature of 57degC.
2. PETG (Polyethylene Terephthalate Glycol)
After mastering PLA, PETG should be your next printing challenge. PETG is similar to the plastic that is used in water and food containers. bottles, however it is enriched with glycol for improved printability. PETG offers numerous advantages over PLA. PETG is slightly more durable as well as much stronger and has a higher resistance to heat. It also exhibits an outstanding degree of creep resistance. This makes it suitable for 3D printing that is functional.
However, it's somewhat harder to print. This is not necessarily a bad thing. While it is virtually impossible for a properly tuned 3d printer to mess up PLA prints however, making sure you get PETG right requires an understanding of the software used for slicing and first layer calibration. This allows you to quickly learn the fundamental concepts of 3D printing. This is crucial to be able to handle more complex filaments.
3. TPE/TPU/TPC (Thermoplastic Elastomer/Polyurethane/Copolyester)
TPE is a collection of polymers that exhibit rubber-like properties. Such filaments are used for applications where flexibility is desired. Regular flexible filaments marketed as TPE can be found in various shore hardnesses, which measures flexibility. In fact, TPE incorporates a broad range of filaments, which includes urethane-based TPU, which is slightly stiffer to enhance printability. TPC is a copolyester-based model that is more resistant to UV, heat as well as chemical agents.
Due to its inherent flexibility, printing using TPE or other variants isn't easy. These filaments are particularly difficult to print using Bowden extruders due to the lack of rigidity makes it hard to propel the filament into the nozzle. To ensure reliable printing, it is recommended to use direct drive extruders with a shorter filament path between the wheels of the extruder and nozzle.
4. ABS (Acrylonitrile Butadiene Styrene)
ABS is used in numerous consumer products, including automobile dashboards and switchgear, toys and pipe fittings. It is also used as the basis for a lot of consumer durables. Its familiarity, affordability, and availability make it the preferred material for 3D printing in commercial applications. It's a terrific material with an unbeatable price-to-performance ratio as well as excellent heat resistance.
Its resistance to heat means it is incompatible with low-cost PTFE-lined hot end. ABS filaments have to be printed at a temperature of 250°C. Hot ends made of all-metal are essential for safe printing. The filament also off-gasses harmful VOCs (volatile organic compounds) such as styrene, which have been proven to adversely impact the health of. Learn how ABS compares to PLA in our ABS Vs.
