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.
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.
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.
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.
You can easily power a 3D printer using an ATX PC power supply. You will need to connect the green PS-ON wire to ground to power the supply on.
You can chose just about any Bowden extruder for the Kossel Mini, I chose Airtripper’s Bowden Extruder.
2. Use an additional printed carriage with Dual 623 V rollers currently around $80.00 after shipping…
In this video I assemble the push rods, effector, and auto level probe.
Push rods: They should be around 180MM and MUST be exactly the same length. If they are all a little bigger or smaller you can adjust in the software. Cut the head off of 12 M4X20 screws and screw the ball joint ends on to the rods, be careful not to split the rods so a tap may be needed.
My first 3D printer was a Prusa Mendel V2 Reprap, after seeing the speed and precision of my bosse’s Rostock Max and drooling over his Kossel mini I decided it was time to make another printer. (You can find my Prusa Mendel V2 Reprap post here) I have found that half the fun of 3D printing is building the machine… especially if you are the type that enjoys tinkering and fiddling with gadgets. I have also found that 3D printing is absolutely a hobby, though, I am to cheap to try some of the more out of the box printers that are developing nowadays. I am not sure if the urge to build things or my cut-rate pocket-book drive my DIY printing hobby more…
Building my very first 3D printer was quite traumatic and time consuming but also fun and rewarding! I don’t suggest building your own unless you have a love for tinkering, and making. There are some other qualities that will come in handy such as tendency’s for hacking, electronics, and computers. As this is a computer controlled machine complete with a microcontroller you MUST know how to turn a computer on. Be aware that building your own RepRap is more like getting a hobby than getting a project.
