Summary

This treefrog is based on a recently discovered species called the Tiger's Treefrog (Hyloscirtus tigrinus) which has an incredible maze-like pattern on its skin. Hyloscirtus tigrinus lives in the rainforests of Ecuador and Colombia and is exceedingly rare. Scientists estimate there are only 250 adult tiger's treefrogs alive today.
You can see some pictures of them here

files

I've uploaded two different frogs, one for printing big and one for printing small. The frogs are designed for dual extrusion 3d-printers and are each composed of two files: a "hollow" one and a "solid" one. If your printer only has single extruder, you could print the "solid" half by itself to make a 1-color frog.

print settings

This is designed to be printed with no supports. We used Makerware's medium settings to print the frog in ABS on our Makerbot Replicator 1 (2 shells, .2mm layer height and 10% infill).
Slicing warning: this takes a while to slice! The frogs took us 13 minutes to slice with .2mm layers in Makerware.

design

I modeled the body in Blender from photographs of Hyloscirtus tigrinus and the pattern was generated using a simulation of reaction-diffusion.

After I print, how do I put the two parts together?

The two parts must be printed together on a dual extrusion 3D-printer.

Very cool looking frog. I printed with my TAZ 4 and cyclops dual extruder hot end. I printed with PLA at speed 30 mm / sec perimeter, 0.2 mm layer height and the surface has a rough texture to it. Will printing slower give me a smoother finish?

Hi I am trying to get my dual printer to work,

Have you got the firmware to work ?
I am using Marlin & RAMPS 1.4,
But cannot get it to compile, with two extruders.

Any info. appreciated

Cheers

Thanks for the fast response. I hope this helps others understand how this model works.

One more question, and I've had this happen with other models, but my old methods aren't working;
I've tried printing a dozen ways, and every time, in the print priview of makerbot, I get a fence like half perimiter around the object; one color on one side, and the other color on the other side, almost like the object almost fully gated in.

Have any ideas on what's going on here? Is it because of a leaky connection? What's the best way to rectify? I really appreciate it...

the makerbot does that by design to limit the drippiness of the dual extrusion process and give you a cleaner print

Why is my tree frog big solid preparing in makerbot as 1 thing file, only allowing me to pick 1 color? THIS SUCKS! How did you guys make the two colors? I have made 2 colored objects in my dual extrusion makerbot replicator 2x, so Im no rookie.

But I'm missing something here. Please help!! I love all the color combos people made btw.

you need to load both parts. please download both the parts. one is labeled "solid" part and the other "hollow." load both in your printer software and set each to a different extruder to print in two colors

Great file, I made one, will upload it soon.

  • How can I get other things to split like this for duel extrusion?

slic3r can't slice the thing at all.
However curaengine can. I've done with purple/milk colors.

dc42 - in reply to klirik

slic3r 1.17 can slice the files if you repair them first - see my earlier comment.

What about the poor old corroboree frog?

hmmmm... maybe we'll do that one in the future.

thanks nice files... has anyone tried it on the da vinci 2.0 duo...

The original STL files are reported by sli3r as containing thousands of errors, which it attempts to repair but does not do successfully. Before I could slice these files, I had to run them through the Microsoft/Netfabb cloud repair service. Slic3r 1.1.7 was able to slice the repaired files.

I have a question. Any idea why it prints a fence around the frog? Has anyone had that happen?
We are new to this whole 3D printing, and was wondering.

If anyone is having any troubles making this print. You have to drop both STL files on top of one another, and merge them.
That is the trick.
I'm sorry if this is a repeat.

the fence around the frog is placed there by makerware to minimize the amount of specs that get stuck to the side of the model.

Is there any way you can post/release the same pattern but inverted?
I was thinking about trying to print (with dissolvable supports) only the stripes. But upon inspection, the model of only stripes has islands of material, where the inverse would not.
Put another way, your main picture is a black frog with green stripes. I would like to print only the black stripes and not the frog (and not the green stripes).

hypothetically yes, but I don't have time to do it at the moment. You could try the same idea with our octopus. Neither side of te octopus is solid http://www.thingiverse.com/thing:67503

Amazing design!
Although it is "Colombia" and not "Columbia" , Im from there and have actually seen this particular Frog alive and kicking in the Colombian part of the Rainforest ! Again, beautiful design! Keep up the good work!

Thanks for the catch, @mararuo -- Fixed our spelling. It would be so cool to see one of these in the rainforest! Glad our design is beautiful to someone who has. :)

Are you guys still planning to release the tool for creating these designs? They're fantastic.

We are still planning to release the tool. Right now it is an amalgamation of different tools we've created, some are web-based and others are not. We are planning to make a single web-based tool to do the whole process but there are a few things we still have to do to make that happen.

Awesome! I have been printing your models for awhile and they are some of my favorite. I can't wait to play around with making some of my own.

Great looking frog!!
