Endless PETG #4 (September 2022) - Blood of my Enemies and Tangerine Orange Metallic

by Protoplant, makers of Protopasta comments

Our 4th installment of Endless PETG adds some more HTPLA favorites to PETG. Amie’s Blood of my Enemies and Tom’s Tangerine Gold Metallic are two hot colors designed in collaboration with two talented creators. A deep translucent “blood” red and an exotic car-inspired orange.


In designing Blood of my Enemies (BME), we went heavy on the red. Heavier than ever! The result? A deep translucent red reminiscent of blood that’s great for cosplay rubies too. Whatever you print, the unique name inspires fun and the unique finish inspires creativity. If this is your first time experiencing BME, you’re in for a bloody good time!


Tangerine Gold Metallic (TOM) was a treat to create. What’s not to love about a Lotus-inspired orange? Automotive fan or not, everyone can appreciate a beautiful automotive finish. TOM has the right amount of gold pearl for a perfect balance of depth, texture, and color. If you are new to TOM, step into the light to enjoy this dynamic color.


We hope you enjoy these Protopasta favorites in PETG!


All our best,


Alex and the Protopasta Team

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.
