Emboss and impress images onto a surface in OpenSCAD #3DThursday #3DPrinting
Really handy embossing in OpenSCAD tutorial from the Cubehero blog:
Sometimes, half the fun of 3D printing is being able to take other formats and convert them into something printable. In this case, we want to be able to convert an image into a surface, a process called embossing.
Embossing is where we take an image and raise the surface on the lightest parts of the image. Impressing is the negative image of embossing, more like stamping an image onto a surface.
To do this, we’ll use the surface() command in OpenSCAD and a command line tool called Imagemagick. If you don’t currently have Imagemagick, go install it, depending on whether you’re on linux (ubuntu), mac (or using binaries), or windows.
Once you have that installed, we can use imagemagick from the command line to convert our image to grayscale.
We’ll use the classic sample image from the field of image processing, lenna.png….
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
