SKU: N/A Categories: , ,

OK, let’s be honest: brown is usually not considered the most exciting color. However, we are here to tell you that is just a terrible misconception. After all, brown is the color of many of nature’s beauties–rich soil; healthy tree trunks; graceful deer; People’s Sexiest Man Alive, Michael B. Jordan; and more. This is why many people associate the color brown with warmth, stability, comfort, and strength.

Plus, brown is the color of two of the most glorious collaborations ever between humans and nature. We speak, of course, of the nectars known as coffee and chocolate.

Besides, once you see this brown 3D printer filament, you will never consider the color to be dull ever again. This HTPLA filament contains metallic flecks, which offer a perfectly subtle sheen to add even more class to your creation.

Our most common use for this brown HTPLA filament has been to pair it with Protopasta’s Cloverleaf Metallic Green HTPLA to create stunning nature-based planters, such as trees in a forest, flowers in a garden, and bears in a field. However, as always, with your creativity, the possibilities are endless.


This rich brown 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.  The heat treating is complete once the print goes from translucent to opaque with reduced gloss.

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.
