Preparing a Slicing Plan for 3D Printing Chain Mail Starting With a Subtractive Model #3dthursday
Some thoughts on rethinking a classic chainmail printed object from Thingiverse with some CAM-specific tuning to improve printing and success with resulting material from Ed Nisley:
This is a subtractive version of Zomboe’s Chainmail, built by removing chunks from a solid rectangle the size of one link, until what’s left is, indeed, a single link.
The pillars in the original model weren’t nearly large enough; Slic3r omitted them from the G-Code. They’re now as wide as the bars and √2 times that width long, which means they actually get a bit of fill.
Then a pair of nested loops replicates that link across the entire fabric.
That technique didn’t work with Skeinforge (because it sent the nozzle scampering all over each layer, knocking things loose) and it didn’t work with Slic3r 0.9.8 (because it had problems with bridges), but Slic3r 0.9.10, hot from github, produced good results. [See Above.]
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!
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
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.
