3D Filaments for Your 3D Printer

What are 3D filaments?

3D print filaments are made of thermoplastics that become flexible when heated at specific temperatures and solidify again when cooled. They are used in 3D printers and 3D pens to build three-dimensional models of precise measurement and shape.

Now that you know what is 3D printer filament is, it is worth mentioning that there are many 3D printer filament types. Among them, ABS and PLA filaments are the most popular types used.
 

Which filament to use for your 3D printer?

To find out the type of 3D printer filament you can use, please check the user manual of your 3D printer (which will also be available online). Generally, most models allow the use of ABS and PLA filaments of 1.75mm diameter. Only certain printer models allow temperatures high enough to melt other filament materials like nylon. Filaments are usually sold in spools by weight, usually ranging from 0.5 to 2kg.
 

ABS 3D filaments

ABS (acrylonitrile butadiene styrene) is a common type used in 3D printing. It is the same plastic used for making Lego blocks, so expect models made with ABS filaments to be sturdy and durable. It is inexpensive and nontoxic, though ABS can emit a chemical odour while printing - you can solve this minor issue by operating the printer in a well-ventilated space with a window open.
 

PLA 3D filaments

PLA (poly lactic acid) is another type of thermoplastic material used for 3D printing. PLA filaments for 3D printers are made from natural materials like cornstarch or soy beans. As a result, it is an eco-friendly and biodegradable option. It also produces a pleasant smell while printing and is a good choice for home use.
 

ABS vs PLA

ABS is less rigid than PLA, but can produce sturdy, durable items and is commonly used for making precise prototype models. Like PLA filaments, it is inexpensive and suitable for casual use at home as well as in manufacturing businesses.

PLA is generally stiffer and stronger than ABS but it is not very heat-resistant. PLA is a great choice for hobbyists and those who are just getting started with 3D printing since it is easy to work with.
 

Storing 3D filaments

Filaments can absorb moisture from the air and result in poor quality models if stored outside for a long period. If you have any unused filaments left over, store them in airtight containers or ziploc bags with silica gel to keep them dry. Buy the best 3D filaments based on your requirements.
