How do you get a reptile snake skin appearance in a 3D print? We stumbled onto a cool method!
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.

New Inova-2008 PETg 3mm 3D printing filament is made in the USA by Chroma Strand Labs and only $40/kg with free shipping!
PETg is one of the hottest new 3d printing filaments, featuring:
- Easy printability
- Low Emissions
- High Strength
- Very High Dimensional Accuracy
- Very Low Warping and Splitting
This means it’s a great fit for anyone that wants strong, good looking prints that “just work”.
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:
- Low dye % across all colors
- Stringent tolerances for consistency of diameter and concentricity
- Premium filament bases
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.
Check out these great new translucent colors of Inova-1800 now only $70/kg, also with free shipping!
Step up your 3D printing with new co-polyesters.
If you’ve tried the new co-polyester 3D printing filaments like Chromastrand Inova 1800 and colorFabb nGen you know how they combine the warp and split resistance and strong bed adhesion of PLA with the strength and heat resistance of ABS, while maintaining lower fume and particulate emissions.
How do you choose? There are three Eastman Amphora series co-polyester bases:
- “Good” is Amphora 3300 is, which we carry as colorFabb nGen. nGen is a big step up from PLA in strength and temp resistance. nGen’s low price makes it a great intro to co-polyesters
- “Better” is Amphora 1800, which increases strength and heat resistance over 3300- similar to ABS. We carry it as Chromastrand Labs Inova-1800, which is a “super premium” filament with ultra low consistent dye percentage, and the most stringent dimensional and cooling managament during production. If you’ve tried other Amphora 1800s, give Inova-1800 a try and see the difference
- “Best” is Amphora 5300, which increases strength and heat resistance over 1800. We carry it as the new colorFabb HT. Amphora 5300 is nearly polycarbonate levels of temperature handling and strength, but with low fumes and easy printability!
If you’ve not tried them yet, you’re in for a treat, try some today!
