Lithophane Filament

I'm experimenting with printing Lithophanes.  I want to know if there is anything special about the Lithophane PLA which is available. Is it just standard PLA with a more expensive price tag on it? So far i've tried ordinary white PETG which was a bit drooly. I've also tried ordinary white PLA which gave a nice crisp image, but perhaps not as translucent as I would have preferred. 

I'm in the UK, and I can't find anything here described as being particularly for Lithophanes. The only filament I've found so far, is on Amazon from a US seller. 

For those of you who haven't come across Lithophanes, take a look at this which someone sent me:

RE: Lithophane Filament

I have always used eSun PLA+ Cold White for Lithophanes and was quite happy with the results. You can also experiment with the thickness of the print to improve the translucency. How did you create your lithophane stls? I used this tool .You can host it on your own web server in your LAN if you do not want to upload your images to the cloud. Here you can find out how to do this.

Yes. It's eSun cold white that i'm using also. The 'Tool' that you linked doesn't work, but I can get there using the other address you linked. I'm using LithophaneMaker.com. Yes I know you can vary the thickness. I've not yet tried altering the defaults of 0.6mm - 3mm. I would be interested to know what thickness range you are using?

Ah, the link perhaps was truncated by copy&paste. This one works: https://3dp.rocks/lithophane/
It has been some time since I played around with that, so I don't remember exactly all the parameters. I generally tried to get the brightest parts as thin as possible. I just went to my local copy of the tool and this screenshot should show the settings I used the last time.

I've got to ask also.... Which orientation are you using for printing? That tool you linked implies that the model should lie flat on the bed. Whereas the site i'm using has the model stood on the long edge. I'm using buttresses at the sides to stop it falling over.

RE: Lithophane Filament

I think the screenshot above just shows the standard values. Because I remember that I created bigger ones than 100 mm. And I always had a little stand on the back. I have just tried to recreate the last one I did with another image and created screenshots of the preview and the settings for it. I will need another posting for the screenshots, I see. I have added a zipped project file of the last lithophane I printed, still with my MK3.

ok. I hadn't realised that your tool allows you include a stand. I think I need to try a print though, with the model flat on the bed, to compare the quality against what i've been getting with the model stood up.

This is how the print of the project above looked in colored light, still on the print bed, lighted with colored light in the enclosure and with a flashlight from behind.
