Innovative Ideas

Here you find innovations from RepRap Squad’s members all over the U.S. as well as others on the web.

New Adjustable Homing Switches
I plan on using these neat adjustable homing switches as they have graduations on them allowing for more accurate adjustment. They also have a very sturdy mounting system.

Here is a new innovative design that has recently been brought up almost as much as, what belt size should I use? Water cooled hot ends. That’s right. There is a couple of new RepRaps on the market recently with this technology. In the $3-4,000 range. I can almost guarantee that it will either become widely used or considered the standard in the future. Here is a design to give you a rough idea of how they are building these.

Bowden Stepper Mod:

This is quite a innovative idea. You’ve seen the bowden cable mods but this one is different. It uses a concept much like Dremel implements with its attachments. It uses a flexible shaft that is mounted to the motor. This shaft will in turn move a worm gear that turns the hobbled bolt and then feeds filament. This helps eliminate a lot of the downfalls of the bowden cable mod. It saves weight on the carriage, which makes for more accuracy and quicker speeds. It also works much like your stock setup, so it has the advantages of the stock setup and the advantages of the bowden setup. With none of the downfalls of either. It is a concept that RepRap Squad has been exploring for a little while now and I’m excited to see it done when we have a functional model.

Remote Bowden
I recently found this variation which has been named by the designer as a, “remote bowden setup.” It runs along similiar principles as the, “bowden stepper mod.” The main difference is the extruder motor is located on the X axis and ran via square rod. The square rod is used so that the extruder can move along the X axis smoothly and it will be able to be turned when extruding. Recently there has been quite a few variations of this. The remote bowden has been built and does function but not without some issues. You can find more information on the remote bowden on the reprap forums.

Berrybot3D–»
For this build he decided to use strong magnetic balls to attach the 6 different rods used for the rostock like axis. He also used carbon fiber rods. The builder is a very nice and innovative builder. Check out the pictures to get a better idea of what I’m talking about. I usually write up a lot more detail about the innovation, but in this case a picture is worth a thousand words. So here’s several thousand words.

Making Your Gears Stay
After looking around the net to find a good way to keep my small extruder in it place. I ran across this little idea. What he did was drill a hole in the side of a nut and then used a tap to thread it. He printed the small gear so it would hold a nut. This idea could be implemented on several different parts of your reprap. Using a set screw or grub screw it will firmly hold it place helping to eliminate slippage and eventual wear.
