Why Would You Need PLA Filament?

Polylactic Acid is the most popular material used in 3D printing today because of its advantages over other options. It’s made from natural and renewable materials, making it environmental friendly.  

It melts at 180°C which is an advantage over ABS filaments which melt at higher temperatures. With its relatively lower melting point, PLA filaments don’t require a heated printing bed. 

What To Look For In PLA Filament

Today, there are many manufacturers of PLA filament. Hence these filaments come with different qualities. Therefore, you must consider the properties of the PLA filament you want to buy before paying for it. Here are some features to look for when choosing PLA filaments.

Filament Diameter: PLA filaments come in different diameters. The most common are 1.75 mm, 2.85 mm, and 3 mm filaments. Although 1.75 mm would be recommended because it’s the most common in the industry and flows better, diameter consistency is the most important factor. Whatever diameter you choose, it must be consistent throughout.

Filament Moisture: If the filament traps moisture during packaging, it will lead to poor print quality which is common. You need to watch out for moisture in filament before buying it. A filament with moisture will splatter and have spiting at its end.

Strength and Flexibility: Low-cost PLA filaments are brittle and fragile, but a PLA filament needs to be strong and flexible. That’ll make it offer smooth prints and increase ease of use.
