Reptile Snake Skin Pattern 3D Print

3d print of a combat robot chassis in translucent green INOVA-1800 filament and cubic infill.

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!

I didn’t start out to have it look like a snake- the pupils in the engraved eyes were originally round, but when I saw another print of the wheel skirts and noticed the reptile pattern, I hopped back in Fusion 360 and quickly changed them to snake eyes!

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.

Custom Pink LulzBot Mini 3D Printer

pink 3d printer lulzbot mini

Jodi wanted a pink LulzBot Mini 3D printer for (last 😉 ) Christmas.

Jamie and Jodi finally finished it!

We collected the necessary LulzBot Mini parts and our friends at Chroma Strand, maker of premium Inova-1800 filament over-coated the bed plate and chassis in “Prison Pink” Cerakote for a tough, smooth finish.

Mini parts coated pink, and 3d printed parts
As the LulzBot logos are laser etched through the factory finish, they still appear through the cerakote.

Printing LulzBot Mini parts with a LulzBot Mini. Reprap FTW! reprap.org The printed parts were printed from LulzBot’s open source Mini files. We used a mixture of Mini V1.03 “Foxglove” and updated V1.04 “Gladiola” pieces (Z lowers, X connector cover, Beefy Idler/latch).  If you have a Mini, be sure to use the production tuned .gcode files for production quality, strength, and blazing fast print speed.  We even have the heat inserts you need.

 

Jodi worked on building her own LulzBot Mini 3D printer. Mounting the cable relief to the left side panel

 

The X/Z carriage assembled using a mix of foxglove and gladiola pieces.

Y carriage and spool arm mounted to the chassis
Final assembly began in earnest over the last few months. XZ assembly, RAMBO and Y harnesses mounted to the chassis Many heat inserts were inserted with the heat insert soldering iron. We salvaged and built the wiring harness (the most difficult item to replicate) in bits and pieces over time until it was complete.
Electronics mocked up in the control box. It’s running!

The result is a beautiful, great printing Mini for (very patient) Jodi. Bonus points for those that can spot the final change shown in these last two pictures.

 

 

 

 

Jodi’s message for you all. Thanks for checking out our build. We hope you’ve enjoyed it!
