Having a lot of fun printing lithophanes lately. This was just a test print when I was trying to tune my settings. Thought i'd put this up to help anyone with lithophanes. :)
Opened in Photoshop Elements, then converted to greyscale. Used the Auto Levels function and saved as jpg.
Imported into Simplify3D through the " ADD-Ins / Convert Image to 3D
60mm Square so not long to print
Printed in 3DFillies PLA+ Lithophane White
Added screenshots of the settings used in Simplify3D
