I used my first RepRap Mendle 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 is the RepRap page for Kossel, it applies 96% to the Kossel XL as it is essentially the same exact thing just 50% bigger.
Stats on this specific build:
- Height 770mm – 30″
- Width 430mm – 18″
- Depth 550mm – 21″
- Print Height 250mm – 11″ (its simple to make this bigger, just get taller vertical extrusions)
- Print Diameter 270mm – 10.5″
The bill of materials is quite complex, it made the most sense to me to put it into an Excel spreadsheet. There I distinguish between core parts and all the added accessories that complete my build. I know not everyone has Microsoft Excel so here is a link to view online in office online or download the spreadsheet.
Cost for parts is in the $400 - $550 range depending on features.
All printed parts can be found on Thingiverse, I list them in the BOM but also have a collection of all the different parts and pieces so you can download the files you want! http://www.thingiverse.com/electronhacks/collections/kossel-xl-2020-complete-parts/page:1
As it is usually part of my process I want to document the build before it is completely finished. I will be adding videos here as I get them uploaded.
