Most Common Types of 3D Printing Filaments

Key Takeaways

Growth of 3D printing has ushered the growth in material technology and this has resulted in development of a multitude of filaments for 3D printing. However, some basic materials are used on a large scale than some of the most recent and innovative materials developed by material scientists. Here, we take a look at some of the most common types of 3D printing filaments available in the market.

Common Types of 3D Printing Filaments

Polylactic Acid (PLA)

Polylactic Acid (PLA) is one of the most common types of 3D printing filaments around the globe. The main reason being the ease of operation, it is affordable and is environment friendly. It can easily biodegrade in 50 days in industrial composters. It is made from plant-based starches and are generally food-safe but still it is advisable to check the safety with the manufacturer before such a use. It does not give out fumes as is the case with ABS. It sticks to the bed easily which helps in faster printing speeds.

However, PLA is not suitable for parts with continuous exposure to heat as it has low heat resistance compared to other 3D printing filaments.

General Printing Settings
Printing Temperature: 180-200oC

Bed Temperature: Room Temperature (40-60oC for best results)
Print Speed: 100-120mm/sec

Acrylonitrile Butadiene Styrene (ABS)

Acrylonitrile butadiene styrene (ABS) is an industrial material and used in many household equipment’s. ABS also is one of the most common 3D printing filament. The most famous application of ABS is Lego bricks. Since this material is already used by many polymer industries, it is mostly used for industrial prototyping. ABS has high temperature resistance and good impact resistance.

ABS has the added advantage that on treatment with fumes of acetone the outer layer melts and we get a smooth & glossy surface finish.

ABS is a toxic material and it gives out toxic fumes while printing so it is recommended that printing should be done in a properly ventilated room. ABS is prone to warping and cracking at edges, so a heat bed is essential to print with ABS. This helps in keeping the printed layer hot avoiding the temperature difference thereby having a stable print experience.

General Printing Settings
Printing Temperature: 210-250oC

Bed Temperature: Room Temperature (90-120oC for best results)
Print Speed: 80-100mm/sec

Polyethylene terephthalate (PET)

Polyethylene terephthalate (PET) is a transparent, strong and highly durable filament. PET is the same material from which mineral water bottles are made. PET has many variants like PETG, PETT, PET+, PETP, PETE, etc. By addition of chemicals the PET materials are called by various other names which also modifies their properties. They closely resemble each other but offer different levels of strengths.

PETG is formed by addition of glycol. Glycol helps the PET material become brittle and eliminates the hazing effect seen during printing. This helps in achieving a comfortable grip on the product but this also renders it susceptible to damage due to UV light.

General Printing Settings
Printing Temperature: 225-275oC

Bed Temperature: 75-90oC
Print Speed: 40-100mm/sec

Polycarbonate (PC)

Generally Polycarbonate (PC) is used to make a lot of household items like containers, flasks, vitamin shaker bottles and even used in manufacturing of bulletproof windows. PC exhibits high resistance to heat and is stronger than most of the 3D printing filaments. It has a high melting point and so the extruder temperature also has to be pretty high with the need for a heat bed.

General Printing Settings
Printing Temperature: 260-315oC

Bed Temperature: 80-120oC
Print Speed: 20-40mm/sec

Nylon

Nylon exhibits high strength, high tear resistance and has excellent surface bonding. It can be easily dyed with needed colours. Nylon is less brittle than PLA and ABS. Most common applications of nylon are in Prosthetics. It has high melting points and so it can sustain friction heat generated during rubbing of adjacent parts. This helps nylon to be used in gears. It is also one of the most durable materials from among the 3D printing filaments.

With all the advantages, nylon has its share of drawbacks. It is difficult to print with nylon as it has higher shrinkage rates than other materials. It is recommended that nylon be printed on Garolite print beds for better control. The print speed for nylon is low.

General Printing Settings
Printing Temperature: 220-275oC

Bed Temperature: 70-90oC
Print Speed: 40-80mm/sec

Polyvinyl Alcohol (PVA)

Polyvinyl Alcohol (PVA) is one of the most common 3D printing filament used as a support material. Since it is a water soluble filament it is ideal for use as a support material and rarely used as an independent material for printing any part. Even though it has better ultimate strength than most other filaments including PLA, ABS and Nylon, it is not a mainstream building material.

It should be stored in dry conditions as humid conditions can deteriorate the material.

General Printing Settings
Printing Temperature: 190-215oC

Bed Temperature: 70-90oC
Print Speed: 40-80mm/sec

High Impact Polystyrene (HIPS)

Another most widely used support material is High Impact Polystyrene (HIPS). It closely resembles ABS but it is dissolvable in a chemical called as Limonene. Unlike PVA, HIPS is also used as an independent material as it shows good durability and high impact resistance. It has stiffness comparable to Carbon Fibre. PVA and HIPS both are now widely used as dissolvable support 3D printing filaments.

HIPS requires a heat bed and so it is generally used in combination with ABS.

General Printing Settings
Printing Temperature: 220-250oC

Bed Temperature: 80-120oC
Print Speed: 40-80mm/sec

Flexible (TPE/TPU)

ThermoPlastic Elastomer (TPE) & ThermoPlastic Polyurethane (TPU) both are flexible 3D printing filaments. Both these filaments are more or less similar but offer different properties. The only major difference is rigidity TPU offers which helps while printing with flexible filaments. The flexible filaments offer high elasticity and flexibility like rubber. The printed part upon application of force is easily bent and twisted and the part returns to its original shape upon removal of the force.

Flexible 3D printing filaments are difficult to extrude and so the print speeds are extremely low.

General Printing Settings
Printing Temperature: 200-250oC

Bed Temperature: 50-75oC
Print Speed: 20-40mm/sec

Final Thoughts

You saw the most common types of 3D printing filaments. As the technology grows, more and more new filaments will emerge and will become common place in the industry. Already materials like Ultem, PEEK, ASA and other super polymers are being adopted by companies for their specific applications.
