RepRap Squad’s Mini 3-D Printer

We’ve built a lot of medium to large sized 3D printers but, we haven’t ever tackled a small or mini 3D printer. I just came across some 5-6mm rods with matching bushings so I thought, ” why not?” Since we are still working on our Aluminum Plus, I figured that I can start on the mini printer while building our Plus. I will continue to update as I go. All design ideas and concepts will be laid out here for others to use.

I’ve started to draw up different designs to see what will work and what won’t work with a mini 3-D printer. I don’t want to dump a ton of money into this build as it’s more of a fun side project. I also want to keep costs down to show that 3-D printers can be built cheaply as I’ve done in the past. More than likely I will use a RAMPS 1.4 controller to run the setup because they can be had for a reasonable amount of money. I’ve started to stockpile parts and separate things that I think will go great for this build.

Here’s a quick design I threw together using Sketchup. I also kept in mind the parts I have available.



My plans for this printer once it’s finished is to use it as a teaching aid. It will be great for transportation, due to its size. Eventually, I will more than likely I will donate it to someone that would have a good use for it.

Update: June 1st 2014
A few more parts that I have collected include Kevlar string which I plan to test with a pulley setup as well as some UMHW that will be used as a swappable bed. I will be custom designing the majority of pieces due the space constraints.


About RepRap Squad

I have been involved with 3D printing for years and I wouldn't have it any other way. I also started a foundation called, "Printing a Future Foundation." The sole purpose of this foundation is to get as many 3D printers as we can into schools via donations. Being an Industry trends adviser within the additive manufacturing community allows me to be immersed in the things I enjoy most.
