Introduction: Lamp From the Masha and the Oso Series Lithophane
Hello Greetings dear friends.
This is my first intructable as my daughter's 2nd birthday is approaching. I wanted to share this lithophane lamp from masha and the bear. cartoon series that my daughter likes to watch and is very entertaining.
For the construction of the lamp a 3d printer is needed since most of its parts are made with 3d printing. and the lithophane canvases are printed with said printer, in addition to other materials that are easily available.
If you want to replicate this lamp, I am going to explain step by step what you should do besides sending you the stl files of each printed piece so that you can replicate it.
Step 1: Selection of Images for the Canvas of the Lithophane
Select 5 images for which you want to make your lamp, whether they are from your family photos or from a TV series or something in particular, you have to select 5 photos or images in jpg or png file, in my case select 4 images referring to mahsa and the bear and one referring to my daughter's name.
A tip for the lithophane to look good and look better is to select an image with clear backgrounds as shown below.
Step 2: Edit the Image and Crop to 1: 1 Ratio
Once the images have been selected, they must be edited, in this case the magnets must be cut out for a 1: 1 aspect ratio or square in the event that the original image does not have such a relationship. if you have windows 10 you can edit the images with the 3d paint program.
Once inside the program you open the image file, select where you say crop it will appear on the screen as the image shown you choose the frame 1: 1 for our case. we click where it says ready and save the file. Now repeat this step for the other images.
Step 3: Transforming Image to Lithophane STL
With the edited images now you have to transform them to lithophane, that is, you have to convert the images to a 3d image with the STL file format, to carry out this step we will go to the next page http://3dp.rocks/lithophane/.
first we choose the file that we are going to transform as shown in the image masha1.jpg Then we select in model a view of the image in 3d will be shown. select the flat option. and then refresh
Before downloading, you have to make various configurations depending on how we want the 3d image to be, we are going to select the thickness, if the image is with a border or without a border the size of the lithophany, now we click on settings -> then image settings we will leave the parameters as shown below in the image.
Now we go to the settings tab -> model settings in this option we will give the measurements on the side of the lithophane in this case it is 70 millimeters we will give it a thickness of 3 mm, in the image we will show the rest of the values.
In the corresponding parameter Base / Stand Depth the value can vary depending on how you want to make the impression, if you want the impression to lie flat on the hot bed you set this value to 0, if you want the impression to be vertical place a value minimum of 3 corresponds to the thinkness that was the corresponding to the lithophane that we are creating.
Step 4: Tips for Vertical Printing or Horizontal Plane
An advantage of printing vertically is that by projecting light onto the lithophane the printed image looks much better than if we print it on the hot bed there are almost no print residue or marks of the nozzle displacement as they occur when we print with the canvas on horizontal.
If you print vertically you can eliminate the edges since when printing the upper edge the filament does not have support in the upper edge and the filament can hang in that part of the lithophane.
a disadvantage of vertical printing is the printing time is always 40% to 80% greater than printing with the canvas resting flat on the bed, also the printing base can be detached more easily and therefore you may lose the impression.
After configuring the canvas parameters of the lithophane, we upload the images and download the files in the STL format. The page already has configured so that the file is downloaded in STL format and we are ready to print all the pieces of the lithopane lamp.
Step 5: Printing the Parts of the Lamp
Now that we have the STL files for the canvases and the pieces that make up the lamp, we are going to print them.
In the attached files I leave you the STL of all the parts so that you can download them. To configure the printing parameters I use the CURA version 4.6 program but you can print the pieces with another program.
In the following magnets I will leave you the printing parameters, these parameters were the ones that gave me the best results because I did several tests. For the impression material use ABS 1.75mm filament and the printer an Ender 3, nozzle size 0.4mm.
For the printing of the lithopane we use an infill of 100% density and for the other pieces of the lamp we can use 30% of the infill.
1x E10 Mini Light Bulbs Screw Base Indicator Light 3.5-3.8V 0.3A
1x lithium battery 3.7v
1x module tp4056
1x Mini Switch 6A-10A D (19.5mm * 13.2mm)
1x silicone bar
4x screws 3mm * 25mm
- 3D printer
- Silicone gun
Step 7: Cube Assembly Upper Part of the Lamp
To assemble the lamp, it is necessary to follow some steps so that it is easy to assemble the pieces of the lamp.
- We are going to start with the center lithophane remember that the size of this is (60 * 60mm), we are going to fit it in the center and fix it a little with silicone on the edges. as shown in image (1) the result is as seen in image (2).
- Now we are going to place the lithophane on the sides what we must do is slide the lithophane as shown in the image (3) we place the 4 lithophane on the sides as shown in the image (4) we fix it with a little silicone .
-Finally we place the intermediate base of the lamp and close the cube. image (5).
Step 8: Lamp Electrical Circuit Installation
In the image (1) in this step the circuit diagram that we are going to make for the lamp is shown, it is a simple circuit where we will use a rechargeable 3.7v battery that uses a push button switch to light a light bulb, the module module tp4056 serves to charge the battery by means of a 5v micro-usb phone charger.
In the images (2) the electrical circuit already installed at the base of the lamp is shown. After placing all the parts in place, you can fix it by placing a little silicone to stick the parts to the base of the lamp.
In the image (3) the light bulb is already lit when pressing the button on the switch, finally in the image (4) the base is assembled with the upper part of the lamp we place the 4 screws and complete the assembly of the lamp.
Step 9: Finishing the Lamp
By placing the screws, the work can be completed, after several days designing, printing the pieces and the lithophane, now that I see it finished I feel happy that my daughter liked it a lot and that is what fills me the most.
These lamps are a nice gift for that special person to whom you want to give, I invite you if you have a 3d printer you can make the same or similar I hope this instructable will also help you to carry out any project related to lithophanes
