Step 2: Conversion of Image to Lithophane

http://3dp.rocks/lithophane/

1) Picture must be cropped to 1x1 proportion to fit the IKEA frame opening 116x116mm

2) Model settings (see picture) :

b. Thickness : 2,8mm

c. Border: 5mm

Step 3: 3D Printed Parts and Assembling

Designed with fusion360 , sliced with Cura and printed on Creality CR10S

1) Front frame : 231 x 231mm, thickness: 10mm,

2) Centering frame with opening for the base of the lithophane,

3) Led lighting support frame for alu V profile, with guides for the wiring system,

4) Lithophane of my grandchildren, but for the example I used the picture : the girl with the pearl earing (https://en.wikipedia.org/wiki/Girl_with_a_Pearl_Earring )and she had a cat .

Step 4: Print Settings

I used white PLA 1,75mm from 3Donline (https://3donline.be/ ) for all printed parts

1) Lithophane : 0.1 layer heigth with a 0.4mm nozzle, 100%infill,

2) All other parts were printed at 0.2mm layer height with 20% infill , infill pattern gyroid,

3) All parts can be assembled by pressfitting them without any glue,

4) The total print time for all parts was about 40 hours , lithophane printing is very slow (20hours).

Step 5: Other Parts

1) IKEA RIBBA White Shadow Box Photo Display Frame 9X9

2) 5050 SMD LED Flexible Strip Light Lamp 12V 50led/m, cool white, I used 4x strips 12 leds,
