Created from our highest quality, translucent HTPLA v2, this stuff is red and sparkly!

Candy Apple Red Metallic PLA prints with the ease of standard PLA with standard hardware and temperatures, but make fun, mesmerizing prints that stand out. Celebrate good times by 3d printing metallic red PLA ornaments, toys, and treasures. If you want to make a print more fun, just add glitter. Glitter Flake Red PLA has little risk of clogging or wearing your nozzle, and it won't make a glittery mess, but beware, printing with metallic glitter PLA is sure to be addictive! Glitter particles are relatively small but have some orientation effects, giving top/bottom surfaces more shine than sidewall, so have some fun playing with orientation to see how the result changes!

Heat Treating

Like our other HTPLAs, Glitter Flake Metallic Red PLA filament can be "Heat Treated" to increase crystallinity for "Higher Temperature" resistance compared to amorphous PLA, ABS, and co-polyesters like PETG! Glitter Flake HTPLA prints translucent, but turns opaque when heat treated (or crystallized). With a more crystalline structure, heat treated HTPLA parts can hold form to near melting, though temperatures where the material is practically useful vary greatly depending on geometry and load conditions!

For this improved performance, your prints should be baked in an oven until you see a change from translucent pink to opaque pink with reduced gloss. This visual change indicates the improved performance! We've seen the change take place in 5-10 minutes on thin walled parts but can take an hour or more. We've had good luck in a quality, at home convection oven at 110C (225F). Parts will get very "floppy" before becoming more firm, so please leave supports on your parts or support them and bake them on a flat, non-radiating surface (like glass, ceramic, or composite).


In our experience, good results were achieved using standard PLA parameters ranging from 195-225C nozzle with standard build surface preparation (blue tape, glue stick, or BuildTak). No heated bed required but up to 60C is okay. Beware, if the bed temperature is too high, your part base could actually heat treat while printing, increasing warping and decreasing adhesion. Some shrinkage will occur in the heat treating process, so dimension critical parts may need to be scaled appropriately (as much as 2.5% in our experience).

  • No abrasive fillers so expect normal wear with standard nozzles.
  • Available in 1.75 & 2.85 (3) mm diameter on a 500g diameter recyclable cardboard spool
  • Usable on most PLA-compatible printers, such as Lulzbot, Makerbot, FlashForge, Dremel, Ultimaker, Printrbot, and more!

Racecar Red

This is absolutely a "racecar red", the Candy Apple description isn't selling the color short. It's bright, vibrant, and a little bit pearlescent. There's a bit of glitter flake that gives it a nice metal flake finish and disguises any layer lines. Like all the Proto-Pasta filaments I've tried so far this one is equally as good as the rest.
