What is 3D Printing Filaments?
3D filaments are material used in the 3D printer for 3D printing plastic, these are plastic materials known as thermoplastics. It becomes flexible when heated to a certain temperature and can be used in the printer. It has the flexibility that allows the printers to sculpt the design and required object before it cools down to its rigid and solid form in the shape of the final product. There are different types of filaments used in 3D printers but 2 most common are
ABS (Acrylonitrile Butadiene Styrene)
PLA (Polylactic Acid)
These two are not the only types and we should discuss other filaments like Sand Stone Filament and Wood Filaments that are rarely used as well as PolyEthylene Terephthalate or PET filaments along with Nylon Filaments, but these 2 are the most commonly used in 3D printing.
ABS (Acrylonitrile Butadiene Styrene) 3D Filament
Acrylonitrile Butadiene Styrene or ABS is easily purchased for $20 for 1.75 mm, 1kg spool, prices do vary sometimes but it should not be less or far above the mentioned price. ABS is popular for its tough and resistant features that appeal to the mass production.
These are very good reasons for their mass use and popularity. It is flexible so it doesn’t break that easy and it is easier to take out of the nozzle of the printer and that is why it is a popular choice for 3D printing filaments. It ranges from 210 – 250 degrees centigrade which is very high for print temperature. It is used in the following production:
- It is great for Plastic automotive parts.
- It is also used to create moving parts.
- Kitchen appliances are a great use as well.
- Electronic housings parts are also made of this material.
- Many toys like LEGO are made of this material as well.
3D printing is not the only use of ABS because it can also be used in traditional manufacturing to make plastic wraps, bottles, and cups. It is popular for filament but it is not the best filament available for 3D printers and home users.
ABS has a very high melting point and needs a very heated surface. This heated surface is not cheap so many budget range printers do not come equipped with this surface for printing. It also has some fumes that are very unpleasant and can be difficult to work with depending on the individuals.
It is due to these reasons that ABS filament is very popular in the industrial use rather than individual use in the homes and small independent workers.
Benefits of ABS filaments
- They are durable and very strong for 3D filaments.
- ABS filament is also lightweight and flexible to use.
- High temperature rating.
- They tend to be too cheap for thermoplastic and are available widely.
- It is favored by the keen protentional as well as armatures for 3D printing
Drawbacks of using ABS filaments
- ABS are made of petroleum-based materials which make it non-biodegradable material.
- It has a very high melting point that cannot be easily achieved and managed.
- Its fumes are very unpleasant to work with and in poorly ventilated spaces it can cause problems for the workers.
Poly Lactic Acid Material or PLA Type 3D Filament
PLA stands for Poly Lactic Acid material used as filament, it is quite popular with both professional users as well as individual amateurs at home or businesses.
PLA is a material made from cornstarch and sugarcane which makes it a better choice due to its nature of organic materials. It is popular because it is a safe material to work with and easier to use, there are no toxic fumes that are created by this filament and this also creates a pleasant and sweet smell of sugar.
When compared to Acrylonitrile Butadiene Styrene or ABS it creates very pleasing and better aesthetic products for the user and it cost around $20 for 1.75 mm, 1kg spool of the
It is much easier to accomplish smooth surface finish with PLA. It may sound like the perfect filament for the needs of many but it is no like that, it does have its flaws as well. It has a lower temperature rating (180°C – 230°C) than Acrylonitrile Butadiene Styrene or ABS and that also makes it weaker if compared to ABS and its products.
It is highly important if you are printing the products that are not the best to handle temperature and perhaps are exposed to heat such as moving parts that are exposed to the heat. These can result in the object melting or perhaps cracking at the exposure of high temperature.
If your products do not have to face the high temperature and work in a different environment that is cold or not very hot, then PLA should be the best filament for your choice.
PLA filament also print faster than ABS material and can produce more products in a given time than other filaments. It also does not need a heated printer surface or a bed to cool the heated product due to its low temperature.
It is used for the following productions:
- PLA filaments are used for Medical stitching or suturing.
- Many surgical implants are made of PLA material like screws, mesh, rods, and pins.
Degradable products that degrade with a certain time period. It is great for making products that degrade over time like disposable products like tableware diapers and packaging materials and products. At the beginner level, it is great to make consumer items for the business and also for the user themselves, it appeals to different demands and different needs at the same time.
Benefits of using PLA Filament
There are no harmful fumes that could cause problems. Produced sweet fragrance when it is heated in the process. It is easier to work for many beginners who are starting in 3D printing if compared to Acrylonitrile Butadiene Styrene or ABS filament materials.
It is less likely to cause any sort of warping in the products. It can also have many different colors as well as effects in the material like transparent or translucent material.
Drawbacks of using PLA Filament
- It can cause clogging of the printer nozzle from time to time which makes it a bit difficult to work with.
- It can produce or attract types of moisture which can make it difficult to 3D print.
- Due to the nature of the material, it has less strength and is less sturdy than ABS.
PET 3D Printing Filament
Poly Ethylene Terephthalate or in short PET is also a very popular choice in 3D printing material. It is commonly used in the making of everyday plastic bottles for companies. PET produced plastic is harmless and is very stable to create and work with. It also does not emit any sort of harmful and toxic smells.
One of the best benefits of this project is that is 100% recyclable so there is a lack of waste and it can be reused at any time. Also, the filament is very clear and has no color in its initial stage. It changes its stage of transparency when it is exposed to heat or cold. Its far advanced version is also known as the Amphora AM1800. Its temperature is 210°C – 230°C and it is used in making:
It is food safe and can be used for food containers.
Cups and plates are made from PET
Kitchen utensils are also made from this material.

- It is approved by the FDA and is safe for food and its containers.
Drawbacks of PET Filaments for 3D Printing
- It is not an easy filament for amateurs to work with.
- Its nozzle its better tuning and maintenances for better results in printing.
Nylon filament which is also referred to as polyamide is also a popular choice in 3D printing depending on the use. It is a stronger filament than Acrylonitrile Butadiene Styrene or ABS and Poly Lactic Acid Material or PLA and it also costs less and is very effective.
Nylon filament is also flexible, lighter, and durable if compared to the ABS and PLA filaments and it is also very less not weak. There are many filaments and they all depend on the use and the budget of the user. Their bonding abilities while printing, tensile strength, and water absorption are the qualities that matter the most while choosing filaments of Nylon base.
Nylon filament temperature is around 210°C – 250°C which is high. Nylon filaments are great to be used in a variety of products due to their strength and flexibility that also help in the durability of the products. It is used in products like:

- It creates toxic fumes when it is melted so it is difficult to work within close places.
- It absorbs moisture from the air so it needs to be stored carefully.
Polyvinyl Alcohol or PVA 3D Printing Filament
PVA or Polyvinyl alcohol is a 3D filament that is considered good as well. The most common use of PVA is to be used as supportive material for the printing process with the use of Acrylonitrile Butadiene Styrene or ABS or Poly Lactic Acid Material or PLA materials. Materials such as PVA that are used as the supportive materials are essential for the printing process.
Without any sort of support for other filaments is hard to 3D print materials and it cannot be perfected without the supportive filaments as well. It is a common and biodegradable material and it also non-toxic so it easily dissolves in water. Most the desktop printers like FDM printers can easily use this material.
It does require a heated bed or building platform to prevent any kind of warping while it is building the 3D object. It works best if the temperature is not higher than 200 °C of the print bed that is being used for the process.
It is also used for the following applications like:
- Supporting material in the 3D printing process.
