QR Code Business Card
Description
Hi there, here is an idea for you. Why not print a business card with a QR code? This one will open my Thingiverse page. I'm also using it for my "Xing" Profile (The german Version of LinkedIn). It is still flexible using PLA and it is a nice give away. A Lithophane maker is used to create the file, although this is not a lithophane in the classical sense. Therefore this is a simpler and easier way to create a 3D printable QR code than some other designs I found on Thingiverse (see the links below). Also it's a differnt way of utilizing Lithophane generators, which makes them even more fascinating. This way any 2D Logo with a few discret colors can be made 3D printable with a few clicks, without having to retrace the whole file manually. There is also a way to do that with blender (see link below) a little more automated, but you have to create the rest of the file, like the baseplate, yourself, which makes the lithophane generator much faster (I'm a noob in Blender). Have fun and please create some designs of your own. I would be pleased to see your version. Also leave me some feedback if you like. _______________________________________________________________ Update 18.11.20: I reprinted the card using 0.1 mm Layerheight and a non shiny black filament (first picture). The quality is much better now, the print is way more detailed. I would recommend to print it this way. All other pictures show the 0.2 mm sliced card. _____________________________________________________________________ How To: 1. Create QR Code https://pageloot.com/de/qr-code-erstellen/#link Make sure you use the color black (will be aesier when generating the Lithophane) export at 200 x 200 px as .svg file or .jpg (see image) Note - On customize you can set the Black squares to be round, looks nice, too. But I think the squares are easier to print, because you will have a few larger blocks of squares. So the nozzle will be lifted fewer times. Also you coul add a Logo to be placed in the middle. 2. Card Design Use Paint.Net or inkscape Standard credit / business card size: 55 x 85 mm Make sure to only work in Black and white (no greyscales) export it as .png file 3. Create .STL File Lithopane - http://3dp.rocks/lithophane/ Drag and drop your 2D business card design and use the settings in the images. 4. Sclic3r Use "quality 0.1 mm" or "Quality 0.2mm" and "Prusament PLA" presets Add a Colorchange after the first layer at which the black boxes begin Prusa article on how t change color: https://www.help.prusa3d.com/en/article/color-change_1687 5. print That's it. Sounds more complicated than it actually is. ______________________________________________________________________ There are some cool and good looking 3D printed QR Code designs on Thingiverse. Nevertheless I think my way is the easiest and fastest. It can also be applied to any other 2D logo, espacially for black and white logos. Designs on thinigverse: These are nice but dual extruded, most of us can't do that trick. https://www.thingiverse.com/thing:12285 https://www.thingiverse.com/thing:2532326 I really like the idea of the cube, but a sharpie was used Maybe I reprint it in two colors. https://www.thingiverse.com/thing:257866 This customizer is great, too. https://www.thingiverse.com/thing:46884 This one is really myterius, I don't know if I dare to print it. But I think trolling people with QR codes could be the new street art trend 2021. https://www.thingiverse.com/thing:3474000 This one is reall cute! https://www.thingiverse.com/thing:2201645 ____________________________________________________________________ Additional Links The idea was inspired by this video: https://www.youtube.com/watch?v=F0IF5PAH7gs&list=PL2bQhO45G947YsHaPGI8EAQxeMsx01tkF&index=2 Paint.Net: https://www.getpaint.net/download.html Inkscape: https://inkscape.org/de/ Creating .STL files from 2D logos with blender: https://www.youtube.com/watch?v=g6cmClwLhz8&list=PL2bQhO45G947YsHaPGI8EAQxeMsx01tkF&index=22&t=73s
