What to Look for in Good Quality PLA Filament for your 3D Printer?

3D Printer

It’s funny that no manufacturer can actually say that their product is of a lower standard. So everyone will be busy convincing clients that their products are the best. As a buyer, you are left wondering who is telling the truth and what product is legit. Poor quality products are all over the market and appear more or less like the good quality ones.

Polylactic Acid (PLA) filament is the best material to use for 3D printing. But the truth is, not all PLA filaments are of good quality, so be careful when purchasing. The guide by Dylan Miller on choosing a good PLA filament for your printer explains that PLA filaments provide good strength and durability, melt at a low temperature, are non-toxic, have a low warp, are safe, and do not shrink as much as other types of printers, among other benefits. How then do you get to know what a good quality PLA filament looks like? This article will take you through what to look for in good quality PLA filament for your 3D printer.

Manufacturing companies can get creepy and produce products that are of less quality for cheaper prices to attract more buyers. They go against the set standards of production to benefit themselves but what they do is fill the market with fakes. They produce PLA filaments that are contaminated with impurities that which block print nozzles. You need to get PLA filaments that are pure.


Every 3D printer is made to handle or work with one kind of diameter. When purchasing PLA filaments, it is important to, first of all, know your 3D printer. The diameter of a PLA filament should be consistent. This means that it is of good quality. Some filaments have different diameters, causing the user to keep making adjustments to their printer. Poor quality filaments are more oval than a circle, which can lead to machine jams. The cross-section of PLA filaments should have cylindrical tolerance for smooth printing.

Manufacturer’s information

Manufacturers of PLA filaments who offer detailed information about their product are more credible. These kinds of manufacturers’ most likely produce PLA filaments that are of high-quality. If they had anything to hide, then they wouldn’t come clean. It’s very easy to hold them accountable for their products. Information provided should also contain details such as the printer settings and melting temperatures.

Operating temperature

To produce products from PLA filament, less energy is required. The temperature subjected to PLA filaments for its melting is low. This is for high-quality filaments, as they do not contain any impurities. Thicker material will require increased temperatures though. A few adjustments have to be made in accordance with printing room temperature as well as the filament’s diameter.


Before we purchase something, the first thing that we look for is the price tag. This is not all wrong because we want to work with our budget. The quality of filaments varies a lot and depends on the particular manufacturer. In most cases, the price may not always indicate quality when it comes to PLA filaments. Cheap products are not always the best but this is not to say that all PLA filaments that are cheap are of poor quality. Sometimes though, cheap PLA filaments could be of low-quality, especially if the manufacturer has used cheap ingredients to make the filament. Poor quality will definitely interfere with the functioning of the printer and won’t provide you with the quality you want for your prints.

As we have seen, PLA filaments are everywhere and can be accessed easily. You could even be spoilt for choice. However, this accessibility should not lead you to make a hasty decision. Quality PLA filaments are important for the final product and the 3D printer. Consider the above to get a good quality PLA filament.
