Print the Next Dimension

When Gutenberg made the first printing press, it took years for his technology to reach the hands of the masses. The first commercially available 2D printers were released centuries after the original’s inception, but fortunately for you, the wait for residential ready 3D printers wasn’t nearly as long. Delivering the parts necessary for assembling a 3D device all your own, the Kossel Kit has everything you need to start printing plastic today.

Breezy Build

Building off the open source technology started by the self-replicating RepRap, the Kossel Kit comes with all of the primary parts you need, including a power supply and glass build platform. After constructing the frame with a few basic tools, simply hook up the electronics and you’re printing in no time. Though the part list is more complicated than a standard Canon, the easy to follow step-by-step instructions will get you there with time to spare. As all the parts are pre-cut and labeled, you won’t run the risk of mixing up what goes where.

Acrylic and Aluminum, Together at Last

Once set up, the three stepper motors work in tandem to control the kinematically linked effector for maximum movement in the x, y, and z axis. Allowing faster and smoother printing, put out as many prototypes as your heart desires without wearing down the machine. It comes at a reasonable price too, thanks to the acrylic hardware, and the auto calibration makes navigation a breeze. Finished off with aluminum extrusions for durability and simple aesthetics, the Kossel Kit transforms your printing process in only a few hours.

The wooden parts will warp with changes in humidity unless painted. The build manual doesn't show the second wooden part in the assembly. There is no large screw supplied that will go thru the board and long enough to put a nut and washer on to attach it to the carriage. Two tiny screws and nuts, and a screw too short are all that attach the plastic to wood. I replaced the axle bolts with a socket head cap screw that is 28mm long and assembled it like the "manual." The weight difference is considerable without all those nuts, long bolt, washers and the extra board. I think I can make this work temporarily. I found this wheel assembly and will probably print something similar when I get the printer working. Some of the cheap bearings supplied are really loose and some preload would help. The tapered wheels I can make myself. http://www.builda3dprinter.eu/shop/kossel-kit/rails-to-wheels-conversion-kit/ The magnetic arms will not make that much difference unless the carriages are running without play on the upright beams. The Traxxus ends are pretty tight and could probably be tightened more with the right socket, a vise and a hammer. Light and tight is the key for better precision and less wear on the machine. Regardless, it's a fun process for me. Just wish some effort was put into documentation of the assembly of a few key things and attention to the rails being protected and clean before shipping. I live on the East Coast so my package was tossed around by UPS many times before it got here. Putting "Fragile" on a package just makes them throw it harder when loading... been there, seen that.
