Galileo 3D Printer RepRap




Introduction: Galileo 3D Printer RepRap

The 3D printer Galileo is a 3d printer open source made by Team Kent's Strapper .It' s a derivated work from the model of the RepRap Prusa from which the movement of the axes X, Y, Z but have been substantial changes that have allowed achieve greater print area and a lower cost of implementations

3 Benefits of the model:

The Premises

The RepRap Prusa has an intuitive design and a system of simple and easy assembly, the plastic parts that make up the structure are easy to handle and require no great difficulty in mounting them with the mechanical structure, and allow to obtain results even without linear bearings and other benefits . The final structure is solid and makes it easy to transport thanks to low weight.

Bigger Dimension

The first step was to increase the size of printable area.La structure has been developed in such a manner so as to have more space to print.

Cheaper Structure

Another significant change has affected the mechanical structure of the new printer.It was find a new structure that could use a smaller number of pieces and always have a solid one .Similar to the mechanical also plastic parts have also been modified where possible or completely renovated. all this has led to savings in economic terms but also in terms of time required to assemble the printer itself

Open Design

The structure of the new printer is made to have an open design that allow subsequent changes in every part, also the X-cart which moves the extruder-it was so designed as to be universal and can be used with any type of extruder .The 'print area is easily accessible for a heated bed or in order to analyze the subject in print a

Benefits of the model:
Quick and easy to assemble Model
Spare plastic Intuitive: easy to assemble and print
Number less than threaded rods
Number less than smooth bars
Amount less hardware
Belts shorter
Open Design

X-Cart is compatible with all types of extruders available

nice design! googling around I found another website that has it

I have a mendel myself!

I like mrmath's comment about not needing it. I am pretty liberal on my tool build and buy budget - if I 'need' it. Tools usually pay for themselves the first time you use them - instead of buying finished goods or paying for services - and it's fun. That said, I am really looking for reasons to 'need' a 3d printer!
Everyone, keep posting the stuff you have 'printed'. One of these will be a need for sure.

And, Great instructable.

I guess that realistically, it would also be limited by the type of plastic that could be used in the printer. Not all plastic is up to all tasks. I'm not sure you could print a spatula that wouldn't melt in a frying pan.

There are plenty of needs for a 3d printer. Theoritically, anything you use that is made of plastic can be printed. Realistically it is controlled by the printable area of the printer. The video at shows how they are making coat hooks. You could make toys for your children, items for the bathroom (I originally thought about a toothbrush then thought about the issue with the bristles), parts for larger projects, building blocks, etc. Of course, it does come down to the cost of driving to the store to buy an item compared to the cost of printing/raw materials. Why take an hour to print a comb when I can buy a package of the for $0.97 at the store? As someone who likes to build things, I am definitely feeling the desire to build one to make additions to my projects. Or imagine printing that costume part for your kid's halloween costume. Who just became the coolest dad on the block?

Of course, this is my opinion and reasoning for getting one. Your's may vary.

I want something like this really badly, but two things keep me from doing it. First, I don't have anything I want or need to build with it, I just think it's cool. Second, since I don't really have a use for it, I can't justify the cost of it. But it would be AWESOME to have one.

How much does this cost? I can't seem to find an estimate anywhere


Reply 9 years ago on Introduction

I don't know about this one in particular... but the cheapest 3D printer I've found was the Huxley for around 450 + tax + shipping from Europe to Canada... so quite expensive....

Is there a place we can buy these plastic parts?
