3D Printed Circuit

pinshape

I'm trying a 3D-printed circuit. I painted this model with conductive glue, and then attached it to a CR2032 battery using a wire. Many ATTINY chips can be programmed using the Arduino IDE. Check out http://www.arduino.cc/ for more info. You can also use http://highlowtech.org/?p=1695 as a reference. I recommend using Arduino as an ISP or In-Circuit Programmer. My previous attempt at conductive ABS from Makergeeks was unsuccessful due to high resistance, so I had to switch to a conductive paint or paste. The Attiny84 Datasheet is available here: http://www.atmel.com/Images/doc8006.pdf. Since the circuit runs at 3V, resistors aren't really needed to limit current for LEDs. However, I did try using an SMT LED, but couldn't get a good connection. This project was my first attempt at learning AutoCAD Inventor, and I'm excited to see what other projects I can tackle. I used AutoCAD Inventor to create the design, which I then exported as an STL file. To avoid issues with scaling, make sure to force it to scale in millimeters during the export process. My 3D printer of choice is a Flashforge Creator X, and I printed this circuit using PLA at a resolution of .1mm. For optimal results, I recommend using a glass plate with aquanet hair spray and adjusting the nozzle temperature to 215 C and the heated bed to 55 C. Keep in mind that most users prefer to use makerware software, but other options may yield better results.
