Endless PETG #3 (July 2022) - Mermaid's Tale Teal and Galactic Empire Purple

Our 3rd installment of Endless PETG adds some more HTPLA favorites to PETG. Galactic Empire Purple and Mermaid’s Tale Teal are both gorgeous and glorious. Both were custom designed for Rose “Maz” Moore and named by the community. How cool is that?


In designing Galactic Empire Purple (GEP), the challenge was to design a dark purple. Maz likes her purples dark! As intended, it's dark, but the abundance of pearl and glitter lighten things up to create a dynamic color that dances in the bright sun. If this is your first time experiencing GEP, you’re in for a royal treat! So park your star destroyer and enjoy!!!

Mermaid’s Tale Teal (MTT) is a sheer anomaly. The challenge was to match the ink of a pen Maz provided and like a gift from the gods, one attempt led to a match! There is something indescribably and indefinably special about MTT. The Filament Librarian literally had trouble quantifying this color. Equaled only by Cupid's Crush Metallic Pink, this Metallic Teal has spectacular sparkle that can only be fully appreciated in person!

Lucky you! You’re experiencing some of the best of Protopasta, and we hope you enjoy!!!

Some 3D printer hardware is more finicky than others, but most machines perform well with 2-4 cu mm/s or more volume flow rate. A Bondtech heatbreak moves the PTFE junction farther away from the hotend for less finicky printing on the Prusa Mini. For Prusa MKs with stock heatbreak, swapping to e3d v6, lite6, or revo components or slice engineering hotend can reduce hang-ups.

All 3D printers can benefit from a calibrated first layer that is not too close to the build platform. Leaving enough room for material to come out without restriction, yet still close enough to stick, is key for more trouble-free printing.
