3D periodic table by EzeSko Jan 2, 2018

Summary

This is a rotary cylindrical periodic table with hexagonal patterns (That reminds to a carbon nanotube), where each element show its abbreviation, mass and atomic weight, therefore, it is very useful and didactic, as well as artistic.

Diameter: 199.4 mm
Total height (full assembly): 324 mm
Total weight: 759 g

Instructions

If you want to print this, to clarify possible doubts, you must first read all the following information:

Body
 For some printers, printing the hexagonal pattern can be a bit difficult without supports. If you print it on PLA with a lot of ventilation, there should be no problems. I use a layer height of 0.3 mm, 100% layer fan and only support for a specific part (see attached images). I include a STL called "Test" to see if your printer will be able to correctly print the body of the periodic table with its patterns, if you have doubts.
 Important: You have to join the Honey Body Bottom and Honey Body Bottom top in the correct position, in the images you can see a suggestion for you to guide.
 To join the two parts of the body, I recommend first sanding the contact surface a little. Then apply a glue. In my case, I used a glue called "La gotita" (that is the name of the glue in my country, but I know that also it is known like cyanoacrylate or super glue) with sodium bicarbonate. This combination generates a very strong union.


Ball Bearing

 I designed the ball bearing to be printed with a layer height of 0.175 mm, so it is better to respect it.
 I recommend printing it with a speed equal or lower than 50 mm/s. 
 It includes a support that ensures that it prints well. It must be easy to remove. The ball bearing work well.


Elements
 Each element is joined by pressure.
 Before printing all the elements, it is a good idea to print a test and see that they fit well in the hexagonal pattern. Depending on your printer, a small scale may be necessary to fit securely. For example, in my case, I had to scale them on the x and y axis by 100.3% (0.3% larger in those axes) , and with that, they fit very well by pressure.
 You can find the elements ordered in groups in the uploaded files.
 You can choose the colors you want. In my case, I gave colors respecting the visible electromagnetic spectrum, and because I did not have an extra color to the halogens (it would have been great to print them of dark blue and the noble gases of violet), I included them inside the nonmetals group.
 The filament change technique allows the hexagon to have a color, and the element abbreviation, mass and atomic weight, another color, which generates a contrast that allows distinguishing it better. Since my printer is a “Prusa MK2” I use the page https://www.prusaprinters.org/color-print/ to do the filament change. I do not know if this method works for other printers, but you have other options:
* Using Simplify3D (I don’t know methods for other slicers)
Watch this video and read its description: https://www.youtube.com/watch?v=OiixypnOS8o
* Manually:
It is more tedious, but you can pause the impression and change the filament, at the desired moment.

Wow. Wonderful design.

Love this design !! Do you know how can it be as beautiful as yours but with a single extruder ? Amazing !

Actually, I did it with a printer with a single extruder. I explain how I did it in the instructions section

Oops ! Thanks for your answer ! ;p

Fantastic! This is a great work of art, as well as being a fun resource for knowledge and learning. Very well done. The colours really bring it to life :)

Thank you very much, I'm glad you liked it.

This is an amazing idea ! Thanks for sharing.

Do you think it would be possible to make a flat version of the grid, to hang on a wall ? That would be awesome !

Of course, there are several ways to do it. You can make a flat support to fit the pieces, that if I should be printed in several parts. Another way is to make each element fit together like a puzzle. You can even print all the elements, paste them with glues on a cardboard-like surface, and then cut according to the shape.

This is brilliant, thanks for designing this. I am fairly new to Fusion 360 could you share the Fusion 360 file for this as well?. Just would love to have a look at the way you drew this up. Thanks

I do not know to what extent it can be of help, I am very disorganized working. Let me order it a little and then upload it.

nice license. I was going to make a container extruded from the hexagons. But I guess you can make that yourself if you want. ¯_(ツ)_/¯

Thanks! You mean one similar to the file that I upload called Honey_Body_Bottom? I can modify it to adapt it to whatever you want.

This is really brilliant.
