When you think of something made out of white marble, what comes to mind? Perhaps you think of a classic structure, such as the Parthenon in Greece or the Lincoln Memorial. Perhaps you think of something a more contemporary, like a beautiful countertop, the hallways of a state Capitol building, or the incredible Sheikh Zayed Grand Mosque in Abu Dhabi, UAE.

No matter what comes to mind, it only reinforces what white marble represents: opulence, class, and timelessness. That is exactly what you get with this HTPLA filament. It has a milky white base with flecks of black built in. When printed, the result is an authentic marble facsimile.

So what kind of planters can you make with this white marble filament? Honestly, anything printed with this material will look great. However, as you can imagine, buildings and statues are particularly stunning.

Just beware, however: you are going to have to answer a lot of questions from your guests about where you got such an amazing marble planter and how you were able to afford it!


This fascinating white-and-gray 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.
