There is a reason that people associate sports cars with the color red. Humans see red as a color that is bold, exciting, and–dare we say?–sexy. Studies have repeatedly shown that teams wearing red jerseys are more likely to win. Research also suggests that both genders find red to be a more attractive color.

Does that mean that if you print a pot using this Candy Apple Metallic Red 3D printer filament, it will win you competitions and dates?  Not necessarily, but it will definitely look great!

This high-temp PLA creates a stunningly vibrant red with tiny flecks of glitter that add just the right amount of glitz to your masterpiece.

With a creative mind and this glorious color, the possibilities are endless. Make a fun fire truck planter or a cheaper alternative to that hot rod you have always dreamed about. Of course, it is also perfect for so many nature-based planters. You can create pots shaped like sun-kissed strawberries, gorgeous flowers, majestic tropical birds, and more.


This vivid red 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 pink to an opaque pink 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.
