Black PLA filament for use in 3D printers. PLA is the most commonly used filament. It’s biodegradable, easy to print, and very strong material. The perfect choice for printing large objects thanks to its low thermal expansion (little to no warping) and for printing tiny parts because of its low melting temperature.

Polylactic acid (PLA) is not poly-acid actually, but rather polyester. But leaving the chemical details aside, it’s, in a nutshell, a biodegradable plastic created from corn starch, potato starch, or other renewable resources. This makes PLA stand out as other filaments are usually derived from petroleum or natural gas. There are many applications of PLA outside of just 3D printing, for example, bottles, shrink wrapping or temporary medical parts.
PLA has a relatively low melting temperature of about 175 degrees Celsius. Unlike so-called thermoset materials, PLA can be heated past its melting point multiple times with very little degradation. It’s also very hard material, but that also means it’s somewhat brittle and once it breaks, it likes to shatter.
PLA is not a perfect material and just like every other plastic has some disadvantages. The low melting temperature also means low-temperature resistance. Parts start to lose mechanical strength at temperatures over 60 °C. Leave your 3d print in a car during a hot day and you might come back to a melted mess. The combination of being both biodegradable and having low-temperature resistance means that it’s not ideal for outdoor use, not to mention low UV-resistance. Another somewhat annoying property of PLA is that it’s only soluble in nasty chemicals like chloroform or hot benzene. So when connecting multiple pieces, you’re better off just using glue.
Even though PLA is biodegradable and the material on its own is food safe, we do not suggest to drink or repeatedly eat from your 3d prints. Because of the small fractures on the print surface, bacteria can build up in there over time. You can prevent this by applying food safe coating.
When post-processing PLA, it’s better to use wet sanding. Without water you'll quickly start heating the plastic by friction, it will melt locally and make it hard to keep sanding.
