16 Different Types of 3D Printing Materials
Below you will find information on 16 different types of 3D printing materials. Chances are that even if you are a 3D printing expert you will learn something new in this guide. You can try magnetic, glow-in-the-dark, or even conductive filaments.
Before we get into 3D materials, it helps to look at the 2D printing process we’ve all come to know. All printers need some kind of substance to print with. For 2D printing, we’re most familiar with inkjet printers that use liquid inks. These machines extrude ink through microscopic nozzles onto papers. 2D laser printers also print to papers. Instead of ink, they use a toner cartridge filled with a special type of fine powder and a heated fuser. 2D printing produces two-dimensional, flat, results that have width and height but no depth (thickness). Pigment-based and solid inks are other materials used for printing in 2D. Today, we can also print in 3D with special machines and printing materials.
2D Printing Compared to 3D Printing
There’s a distinct difference between the two technologies. 3D printers build real-world objects, whereas 2D printers publish text and graphics on papers. Before either machine can print, they need computer-generated, digital files. These files tell the machines what to produce and how to print it based on user preferences. Both types of printers use inks, or materials, to carry out the job. That’s pretty much where the familiarities end. 2D printers can’t build layers to produce real-world objects.
One of the most important parts of 3D printing is to use the right kind of material for the job in hand. In this guide we look at the range of 3D materials, also called filaments, a 3D printer uses, starting with the most popular. We’ll also cover their uses along with pros and cons for each type. This will help you to make better informed decisions when buying your 3D printer filaments. Before you print anything in 3D, there are a few basic questions you should ask yourself, the main ones include:
- Strength: How strong does your printed part have to be?
- Flexibility: How flexible does your part need to be?
- Accuracy: How important is precision to your 3D part?
- Special conditions: Any other conditions that apply to your 3D model
These are the 3D printing materials that are covered in this guide:
- ABS Filament
- PLA Filament
- PET Filament
- PETT Filament
- Nylon Filament
- PVA Filament
- Sandstone Filament
- Wood Filament
- Metal Filament
- HIPS Filament
- Magnetic Iron Filament
- Conductive Filament
- Carbon Fiber Filament
- TPE Filament
- Glow in the Dark Filament

3D Filament Defined
3D filaments are special types of plastics called thermoplastics. Once heated to the right temperature, thermoplastics become flexible. It’s this pliability that allows the printer to sculpt the filament to create your shapes before it cools down. In 2017, the two common types of 3D filaments are:
- ABS (Acrylonitrile Butadiene Styrene)
- PLA (Polylactic Acid)

These are not the only 3D filaments available. We’ll look at other types later in the guide. For now we’ll focus on ABS and PLA, and see what makes them such popular choices. For each material we’ll start with a short introduction followed by the average price, print temperature, and applications. At the end of each 3D material we’ll list its pros and cons. Also worth noting is that not all 3D printers can utilize both ABS and PLA. Some can, but not all, so you need to know your 3D printer capabilities as well as the abilities of the 3D filaments.
1. ABS 3D Filament
PRICE STARTING FROM: $20 for 1.75 mm, 1kg spool
ABS is popular for good reasons. It’s tough, and has impact-resistant properties. It’s this strength and moderate flexibility that makes it such a great choice for printing in 3D. It’s also easy to extrude from the printer’s nozzles, which makes it an easy material to work with.

ABS print temperature range: 210°C – 250°C (high)
ABS is a great choice for printing plastic automotive parts, moving parts, musical instruments, kitchen appliances, electronic housings, and various toys, like LEGO. It has other applications too, aside from 3D printing. For example, traditional manufacturers use ABS to make plastic wrap, water bottles, and cups, to name a few uses. Despite its popularity for 3D printing, ABS is not the best filament for most home users. This is because it has a high melting point that needs to print on a heated surface, or bed. A heated printer bed is not something a lot of budget-range 3D printers come equipped with. Printing with ABS also produces unpleasant fumes that can irritate some people. Needless to say, good ventilation is essential. These things combined make ABS a material favored more by professionals than amateur users.
Check Price of ABS Filament on Amazon
- A durable, strong 3D filament
- Quite flexible and lightweight
- Cheapest thermoplastic available at the time of writing
- Most favored material among professional 3D printers and keen armatures
- ABS is petroleum-based, making it a non-biodegradable material
- Needs a high temperature to reach its melting point
- Creates unpleasant fumes, most notable in poorly ventilated spaces
2. PLA 3D Filament
PRICE STARTING FROM: $20 for 1.75 mm, 1kg spool
PLA (Poly Lactic Acid) is popular for amateurs and professionals alike. It’s a special type of thermoplastic made from organic materials, namely cornstarch and sugarcane. The main benefits of PLA are that it’s safer and easier to use, and with no toxic fumes to worry about. Some users even find the sweet smell of the sugar-based filament pleasant. Compared to ABS, PLA produces 3D parts which are more aesthetically pleasing. This finish is thanks to its unique sheen and smooth appearance.
You might think it sounds like the perfect solution, but there are some drawbacks. For one, the melting point of PLA is much lower than ABS, and that makes it weaker. This matters if you’re printing moving parts or exposing the parts to high temperatures. Both of these things can result in the 3D objects, cracking, warping or even melting. If none of the above applies to you and your 3D projects, then PLA should be your filament of choice. It will award you with superior print details and is also less prone to printing errors during the build process.

PLA print temperature range: 180°C – 230°C (low)
PLA has wide-ranging uses. At the professional level, PLA filament uses include medical suturing (stitching). We can also see PLA used for various surgical implants, including surgically implanted pins, rods, screws, and mesh. The applications work thanks to the material’s degradable properties. All the aforementioned 3D printed parts break down in the human body. They can take anywhere between six months to two years, depending on the part and its purpose. At the amateur level, PLA filament is great for producing a whole range of consumer items. Other benefits of PLA are that it prints faster than ABS, and there’s no need for a heated printer bed. The end products are a decent strength, durable, and offer some degree of impact resistance. Aside from 3D printing, other products that use PLA include food packaging, disposable tableware, and diapers, as a few examples.

PVA (long name Polyvinyl alcohol) is a good 3D filament that’s typical use is as a support material when printing with ABS or PLA. Support materials are necessary when printing 3D parts with notable overhangs. Without the support, these parts would be impossible to print or perfect. As a support material, PVA works best with printers that have duel extruders. This is a biodegradable, non-toxic material that easily dissolves in tap water. All popular desktop FDM printers can use PVA with a heated build platform as this prevents warping during the build process. For best results as a support material, the print bed temperature should not exceed 200 °C.

Choosing the Right 3D Printer Filament
This guide gives you a good insight into the different 3D printer filaments on the market. There are others, but the ones listed here are the most widespread, easy-to-source materials at the time of writing. Before you choose the right filament for your next job, you need to check a few boxes. For example, as well as knowing what you intend to build, you also need to understand your printer’s capabilities. Not all 3D printers are able of printing in all 3D materials.
You also need to prepare for trial and error if you plan to experiment with some of the more tricky filaments. Another consideration is the diameter of the filament, either 1.75mm or 3mm. If you’re unsure, always opt for 1.75mm as it’s easier to work with. 3D filament storage is another crucial area to think about. These plastics can absorb moisture from the air which can mess with the printing process. When not in use, a good way to store your 3D filament is to use vacuum bags that have a double zipper line for better, airtight sealing.
And finally, don’t allow the cheapest of the cheap filaments tempt you as they could prove to be a false economy. Seriously, low-cost, low-grade 3D printing filaments are more likely to contain chemical impurities. These impurities can result in unsatisfactory printed parts and clogged-up printer nozzles.
It might all sound like a lot absorb, but none of this takes long to pick once you start to dabble.
