Lithophanes are essentially embossed photos generated by a 3D printer. The print results don’t show much at first, but shine some light through one and you’ll be amazed by the details. The way it works is that light passes through the thin parts while being blocked by the thick parts.
What is a Lithophane and how does it work?
Well, a Lithophane is a 3D representation of a photo that can only be seen when illuminated from behind. A gray-scale representation of the image is created and then depending on the color it is then converted to a calculated 3D printed height. This allows a specific amount of light to shine through.
What is Lithophane filament?
Lithophanes work by letting light pass through the 3D printed model and create shadows that show your original image. Darker areas print with more density, and lighter areas have less density to let more light through. So the best filament for lithophanes is any kind of white PLA with a decent dimensional accuracy.
Can I print a Lithophane flat?
The first option for your 3d printer setup is to print your Lithophane laying flat on the bed, with the textured side of the image facing up or print your Lithophane vertically. As each layer is printed it the filament is “squished” into the print bed.
What is illegal to 3D print?
In most cases, yes. Federal law permits the unlicensed manufacture of firearms, including those made using a 3D printer, as long as they include metal components. The state also criminalizes the manufacture, sale, or possession of undetectable firearms, and made it illegal to purchase parts to make an unserialized gun.
How thick is a 3D print lithophane?
The first one is “MODEL” and it allows us to adjust the size and resolution of the lithophane. I recommend you start with a Maximum Size of 150 mm, a thickness of 3 mm, and 0 for the border. “Thinnest Layer” allows us to choose the smaller width of the image.
Do lithophanes have to be white?
Lithophanes don’t have to be white but light passes through white filament a lot better, so it produces higher quality lithophanes. It’s definitely possible to 3D print lithophanes in different colors, but they don’t work as great as white lithophanes.
What material is used for Lithophane?
Avonite is a material with translucency properties similar to Corian and gives good results when used for lithophanes. Plexiglas or Acrylic (white translucent) can also be used and although cheaper and more widely available, these materials are often more difficult to machine.
What makes a good Lithophane?
The best lithophanes are made by printing them slow. In general the slower the better the result will be. Therefore it is a CONSIDERATION between time and quality. We like to print at 45 mm/s but this is already pretty fast for lithophanes, however we get good results without losing too much detail.
How do you make a Lithophane in Photoshop?
How to Create Lithopanes in Photoshop Choose a source image. To make a good lithopane, your source image needs to be bold, clear and, above all, high in contrast. Run the Action. Fix the original. The corrected lithopane. The view from above. The printed result. The backlit view.
Should I print lithophane flat or vertical?
Layer heights should be as small as possible to avoid visible vertical bands, and the lithophane should be printed in a vertical orientation, to avoid the print sagging due to a lack of support. Infill is best set to 100%.
What is lithophane resolution?
The lithophane resolution is the distance between pixels in the printed lithophane, so a value of 0.3 mm/pixel means that each unique lithophane thickness is 0.3mm apart in the x and y dimensions. The overhang angle determines what becomes your overhang angle when you print the lithophane vertically.
Is it illegal to 3D print a car?
Patented Objects: Having a patent on an invention or innovation means no one else can create, use, or sell a product without the patent holder’s permission. Therefore, 3D printing of a patented object is illegal, and the patent holder could sue for patent infringement.
Can bullets be 3D printed?
The most notable 3D printed firearms. The weapon can hold 5 bullets at once in its 3D-printed barrel. In November 2013 Solid Concepts, now a Stratasys brand, 3D printed an operational metal gun. The Browning 1911 Metal Replica fired more than 600 bullets without any damage to the gun.
Can a 3D printed gun fire?
This ease of access prompted much of the fear first leveled at 3D printed guns, especially because despite being made almost entirely of plastic, these guns still fire live ammunition and can absolutely kill or maim their targets. Despite this however, they have proven to be less than effective weapons.
Should a lithophane be 100% infill?
If you’re going to print your lithophane vertically, it’s best to set the layer height as low as possible. Since we want all the details, it’s better if you don’t print at high speed. Try to keep it lower than 2000 mm/min. Setting the infill to 100% will let the light do its trick better.
What infill should I print lithophane?
If you were to print your lithophane using the standard 20% infill you will see a bunch of gridded lines as light shines though your lithophane. Yes! I know this from experience! Instead you want to set you Infill to 100% this will make a solid lithophane.
How big should a lithophane be?
I recommend a resolution of at least 200 pixels per inch. For instance, if you were printing a 2″ x 3″ wallet size lithophane, I would recommend submitting at least a 400 x 600 pixel image (2″ x 200 pixels + 3″ x 200 pixels).
How do you make Lithophane color?
You can create your lithophane in four simple steps: Upload image tab – Upload the image you want to convert into a lithophane; (Optional) Edit image tab – Enhance the image by increasing the contrast; Create mode tab – Design and tweak your 3D model lithophane; Click on download button.
