Print with the ease of standard PLA with standard hardware and temperatures, but make fun, mesmerizing prints that stand out. Celebrate good times by printing toys, treasures, and keepsakes. If you want to make a print more fun, just add some metallic pop! Our metallic finish contains no actual metal and has little risk of clogging or wearing your nozzle, and it won't make a glitter mess, but beware the printing is sure to be addictive! Metallic 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! We recommend 0.2 mm layers for the best result. Like our other HTPLAs, Metallic HTPLA can be "Heat Treated" to increase crystallinity for "Higher Temperature" resistance compared to amorphous PLA, ABS, and co-polyesters like PETG! Glittler Flake HTPLA prints translucence, 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 the performance, your prints should be baked in an oven until you see a change from translucent to opaque with reduced gloss. This visual change indicating 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).
