Proto-Pasta's Blue Wonder is a one-of-a-kind metallic blue PLA filament. it has translucent properties and has big multi-color flecks inside! This is a non abrasive filament so it does not require any special nozzle and prints with normal PLA settings.
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).
