The color black is one of the most mysterious colors in the spectrum. Throughout history, some people have thought of the color as a good omen (even that it makes you look slimmer!) while others have worried it symbolized something sinister. For example, look at the way different cultures have interpreted a black cat.

Indeed, the varying views of the color are why this jet black filament is so versatile. You can use it to show the inkiness of night, and you can use it to make an adorable pug puppy. The possibilities are endless.

Of course, one of the main reasons to use this black HTPLA is because it looks sleek and powerful. After all, this is why black remains the traditional color of tuxedos and one of the most popular choices for luxury vehicles. That is why one of our favorite planters to make with this filament is a solid one-color pot.

Many of the most dominant members of the animal kingdom are black as well, such as panthers, bears, snakes, and whales, and they all make gorgeous planters as well.

In short, Black is beautiful–and this filament shows it off in all its glory.


This charcoal black filament prints just like regular PLA. There are no abrasive fillers to excessively wear out your nozzle. There are also no large particles that will lead to jams.

Heat Treating

This Protopasta HTPLA can be heat treated through baking, which is great news if you need improved heat resistance compared to normal PLA. To heat treat, the manufacturer suggests a temperature of 225°F with convection for the best results.

It is important to realize that when you heat treat, printed parts will get “floppy” before firming up. To keep your planter looking its best, provide supports and bake on a non-radiating surface, like glass or ceramic.

Also, please note that some shrinking may occur if you decide to heat treat this product.
