We printed the Marvin Keychain in PETG on our TAZ 5 modified with open rails, Cura high quality, .35mm nozzle. Camera is mounted to the bed on a bracket
I was printing a combat robot chassis and stumbled upon this happy accident of a snake / reptile skin effect. To get durability in a bot for the “plastic ant” class, with its 1lb weight limit, and requirement that chassis and weapons must be 3D printed using only PLA, ABS or PETg, I used Chroma Strand Labs INOVA-1800 translucent green 3D printer filament, mainly because it looks cool- Watch for translucent green in Chroma Strand Labs’ value priced INOVA-2008 PETg soon!
The LulzBot Mini made a beautiful print, and the build volume was “just right” for a plastic ant. A good rule of thumb- If you need a LulzBot TAZ‘s build volume, your ant is going to be too heavy (ask me how I know..).
I created the model in Autodesk Fusion 360 (free for maker / student / non-commercial use!!) which has been an easy to use yet staggeringly powerful 3D modeling tool for quickly iterating through designs. The cloud sync makes it a snap to move between computers!
The key to is the infill pattern. I was experimenting with different infill patterns in the new CURA 2 LulzBot Edition Alpha and chose cubic for it’s strength. By happy accident, the combination of the translucent green INOVA-1800 and cubic infill yielded this cool pattern! Pictured don’t really do it justice as the surface is shiny, and the pattern shifts as it catches the light.
Inova-2008 joins Chroma Strand Labs Inova-1800 Amphora Co-Polyester as a premium quality filament. Chroma Strand blends and extrudes it themselves to give you:
Why do these matter? Dye doesn’t print the same as the filament base. Chroma Strand Labs goes to the extra expense to keep dye composition low so their filament prints the same color to color and batch to batch.
