This is @Louise_Driggers 's fabulous “Adalinda: The Singing Serpent” from thingiverse, printed at its default size (about 15cm / 6" high) in @Faberdashery_Ltd 's Orange Fizz PLA using #VelocityPainting.
VelocityPainting (yes, I made term up is varying the print speed (but not the temperature) to map a pattern or image onto the model – I’m using a perl script to post-process the GCODE from Simplify3D to chop up the vectors where necessary and then mess with the extruder feed rate.
Note: I’ve lit this well to show off the affect – it’s subtler in flat light, but still rather beautiful.
Interestingly, the flames (so the shinier, lighter orange areas caused by printing slowly) are noticeably thinner-walled – i.e. you can easily feel them as an indentation.
210C and a mixture of 10mm/s and 35mm/s. 11.5 hours of printing on my @Think3dPrint3d Kossel Mini.
Slow == thinner? That’s the opposite of what I was seeing when I was experimenting. I’d be very interested to see your perl script (no matter what state - I know perl pretty well as I have modules on CPAN and contributed to Slic3r for a while).
@Mark_Hindess@Nate_T@Alex_Wiebe and others. My Mistake – fast -> thinner, which makes more sense! The fast parts are the lighter, more iridescent parts of the pattern. Here’s the mapping of speed to pattern missing/deleted image from Google+
I was so expecting the saturated orange parts to be the slow parts that I got the sense of the speed wrong. It turns out that saturated more matte parts are those printed at low speed.
@Mark_Wheadon Are you effectively projecting the image through the the whole model from one side then? I was wrapping the image around which is easy on the simple cylinder, but a bit more complicated with anything else.
Was just thinking how you could combine both methods to apply textured scales on the outer or second perimeter and still have the flame effect running through…
How much do you adjust the extrusion to make up for the speed?
@_x111 That wood be neat. My script isn’t sophisticated enough to map the scales like that but it certainly could map different images or patterns to different perimeters, which could look cool. I don’t adjust the extrusion to match the speed but speed shouldn’t really change the amount of filament that needs to be extruded between any two points?
@_x111 The interesting affect of projecting the image through the model rather than wrapping it round is that when you view the image face-on it looks flat and undistorted even though it’s on a curved surface. So it can be a neat effect.
@Mark_Wheadon My version of the “projection” method is not quite as clean but kind of working, maybe its the model, maybe it’s my picture… probably just my coding
Have to see how it prints…

It’s difficult to find the time for anything more sophisticated.
