QR Code Business Card

prusaprinters

<p>Hi there,<br/> 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).</p> <p>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).</p> <p>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.</p> <p>Update 18.11.20:<br/> 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.</p> <p>How To:</p> <ol> <li>Create QR Code<br/> <a href="https://pageloot.com/de/qr-code-erstellen/#link">https://pageloot.com/de/qr-code-erstellen/#link</a><br/> Make sure you use the color black (will be aesier when generating the Lithophane)<br/> export at 200 x 200 px as .svg file or .jpg (see image)<br/> 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. </li> </ol> <ol> <li>Card Design<br/> Use Paint.Net or inkscape<br/> Standard credit / business card size: 55 x 85 mm<br/> Make sure to only work in Black and white (no greyscales)<br/> export it as .png file</li> </ol> <ol> <li>Create .STL File<br/> Lithopane - <a href="http://3dp.rocks/lithophane/">http://3dp.rocks/lithophane/</a><br/> Drag and drop your 2D business card design and use the settings in the images.</li> </ol> <ol> <li>Sclic3r<br/> Use "quality 0.1 mm" or "Quality 0.2mm" and "Prusament PLA" presets<br/> Add a Colorchange after the first layer at which the black boxes begin<br/> Prusa article on how t change color:<br/> <a href="https://www.help.prusa3d.com/en/article/color-change_1687">https://www.help.prusa3d.com/en/article/color-change\_1687</a></li> </ol> <ol> <li><p>print<br/> That's it. Sounds more complicated than it actually is.</p> <p>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.</p> <p>Designs on thinigverse:</p> <p>These are nice but dual extruded, most of us can't do that trick.<br/> <a href="https://www.thingiverse.com/thing:12285">https://www.thingiverse.com/thing:12285</a><br/> <a href="https://www.thingiverse.com/thing:2532326">https://www.thingiverse.com/thing:2532326</a></p> <p>I really like the idea of the cube, but a sharpie was used Maybe I reprint it in two colors.<br/> <a href="https://www.thingiverse.com/thing:257866">https://www.thingiverse.com/thing:257866</a></p> <p>This customizer is great, too.<br/> <a href="https://www.thingiverse.com/thing:46884">https://www.thingiverse.com/thing:46884</a></p> <p>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.<br/> <a href="https://www.thingiverse.com/thing:3474000">https://www.thingiverse.com/thing:3474000</a></p> <p>This one is reall cute!<br/> <a href="https://www.thingiverse.com/thing:2201645">https://www.thingiverse.com/thing:2201645</a></p> <p>Additional Links</p> <p>The idea was inspired by this video:<br/> <figure class="media"> <oembed url="https://www.youtube.com/watch?v=F0IF5PAH7gs&amp;list=PL2bQhO45G947YsHaPGI8EAQxeMsx01tkF&amp;index=2"></oembed> </figure> </p> <p>Paint.Net:<br/> <a href="https://www.getpaint.net/download.html">https://www.getpaint.net/download.html</a></p> <p>Inkscape:<br/> <a href="https://inkscape.org/de/">https://inkscape.org/de/</a></p> <p>Creating .STL files from 2D logos with blender:<br/> <figure class="media"> <oembed url="https://www.youtube.com/watch?v=g6cmClwLhz8&amp;list=PL2bQhO45G947YsHaPGI8EAQxeMsx01tkF&amp;index=22&amp;t=73s"></oembed> </figure> </p> </li> </ol>
