3D Periodic Table

cults3d

This is a rotary cylindrical periodic table with hexagonal patterns reminiscent of carbon nanotubes, where each element displays its abbreviation, mass, and atomic weight, making it extremely useful, didactic, and artistic. You can see the 3D model in real-time here: http://a360.co/2lu27wQ And check out my color scheme here: http://a360.co/2DEzm83 Watch this video to witness the finished product: https://www.youtube.com/watch?v=0B7zKwwB8DA And this one to understand the assembly process: https://www.youtube.com/watch?v=d52YoaQfFIk If you like this design, let me know. ------ INSTRUCTIONS ----- If you want to print this, to clarify potential issues, first read all the following information: ----- Body ----- • For some printers, printing the hexagonal pattern can be challenging without supports. With PLA and adequate 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've included an STL called "Test" to see if your printer can correctly print the body of the periodic table with its patterns; if you have doubts. • Important: You must join the Honey Body Bottom and Honey Body Top in the correct position, as suggested by the images. • To join the two parts of the body, I recommend sanding the contact surface a little first. Then apply a glue. In my case, I used a glue called "La gotita" (known as cyanoacrylate or super glue) mixed with sodium bicarbonate, which generates an extremely strong bond. ----- Ball Bearing ----- • I designed the ball bearing to be printed with a layer height of 1.75 mm, so it's best to respect this setting. • I recommend printing it at a speed equal to or lower than 50 mm/s. • It includes a support that ensures it prints well; this must be easy to remove. The ball bearing works perfectly. ----- Elements ----- • Each element is connected by pressure. • Before printing all the elements, it's a good idea to print a test and see if they fit well in the hexagonal pattern. Depending on your printer, you may need a small scale to ensure a secure fit. For example, I had to scale them 100.3% larger in the x and y axes to get a perfect fit by pressure. • You can find the elements organized by group in the uploaded files. • Choose the colors you prefer. In my case, I used colors following the visible electromagnetic spectrum; since I didn't have an extra color for the halogens (it would have been great to print them in dark blue and the noble gases in violet), I included them inside the nonmetals group. • The filament change technique allows each hexagon to display a different color, making it easier to distinguish between elements. Since my printer is a "Prusa MK2," I use the page https://www.prusaprinters.org/color-print/ to perform the filament change. I'm not sure 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: This is more tedious, but you can pause the print and change the filament at the desired moment.
