Mars rover remixed and inspired by bolbots mars rover on Thinigverse. http://www.thingiverse.com/thing:1583399
The rover uses an Arduino 101 for brains, BLE for communication, and the Blynk app for remote control.
Kossel XL 2020 RepRap
I used my first RepRap Mendel Prusa 2 to print my Kossel Mini. The Kossel Mini has been a wonderful printer but I wanted something a tad bigger so I embarked on a journey to build a big Kossel RepRap 3D printer. As of writing this post there is a significant lack of affordable kits for large Kossel printers out there so I found some inspiration online and started building my own Kossel XL 3D printer. I am very proud of the results, its gorgeous and prints great!
If you don’t know already, RepRap printers are open source, no one owns them, you do! The community has a lot of information on building your own self replicating 3D printer, http://reprap.org/wiki/RepRap
Here are some 3D printer accessories and modifications I couldn’t live without.
Here is a nice looking filament spool holder to go with my Kossel Mini 3D printer. It uses printed parts and 15x15mm Mitsumi extruded aluminum. The rod is 8mm or 5/16 diameter. You can make this holder as large as you want. Read More…
I finally came to the point where I had to figure out a heated bead for my Kossel Mini 3D printer. It is OK to print smaller objects using PLA plastic without a heated bed however to print larger objects or use ABS you must have a heated bed to prevent warpage.
It is a bit of a chore to research all the different types of hot ends and attempt to figure out which one to sink your cash into. I have had over six different types of hot ends, by far the J-Heads have been the best.
I started out with Airtripper’s direct drive extruder on my 3D printer and while I liked it a lot I found out that normal stepper motors will not work. You need a hefty stepper motor and even at that I doubt the ramps stepper drivers can handle it. It is suggested to use a gear reduced stepper with something like a 4:1 step down, these are fairly expensive so I opted to build a Greg’s extruder which has the approximant 4:1 step down that I needed.
This fan duct bolts right on to a RepRap carrage and is meant for a 30MM fan. You will have to drill your own holes. Read More…
There are many options for 3D printer electronics. I like to use the Arduino Mega along with a RAMPS 1.4 board, as I already have lots of Arduino experience. Read More…
