Inner Bone Lattice Structure

thingiverse

Hello, everybody! This is a free visual aid for my Nettfabb tutorial / lesson on custom lattice structures for hollowed 3d models. And it's well suited for photo polymer and metal powder printing. So you can print this sample immediately, and forget about the need to assimilate the material, if all that is not so important for you! :-) Scale it up if you want because it is a high poly! The photos show the result of the lesson, printed a half of hollow sphere with an embedded structure in the form of an array of bone tissue, using Autodesk Netfabb®. Pictures in high resolution are here https://cloud.mail.ru/public/PjVi/SwQDpkx75 Web Page of tutorial http://geosstep.ru/en_Bone_Struct.html in Russian http://geosstep.ru/ru_Bone_Struct.html Strictly speaking, this is a Kelvin structure, but we are not suggesting that you do mathematics! Just and only 3D modeling! We will be glad to see you among the students carefully studying this useful material! We have outlined a method for producing the lattice structure of the nature form we have 3D modeled on the bone structure basis of representatives of the animal world of Earth, both living around us today, and long ago extinct. Well known, this structure is the result of centuries of evolution, which means that it has been tested for millions of years and approved with life itself! We have noticed that the cell profile of this remarkable sequence is very good and suitable for its reproduction in the thickness of massive parts when 3D printing of various products in technology and art. This form is undoubtedly one of the best solutions for saving print materials, resins, metal powders, polymers, energy and, in some cases, the time. It will significantly reduce costs for production and reduce the weight of future products while maintaining strength. Therefore, we built a model of the cell of the internal structure of the bone, prepared the model for printing and printed a sample.Here ie the video about it https://youtu.be/uMww13FCgsI 13:10 May 01 2021 Add Kelvin structure single cell 19:06 May 05 2021 Today I thought that the Kelvin structure cannot be discussed without comparison the Weaire-Phelan structure! https://en.wikipedia.org/wiki/Weaire%E2%80%93Phelan_structure We happy to create 3D models of such a high generative, bionic, modern and incredibly cool structure for our students! Please 3D print 8 pieces for a visual representation the structure periodicity. You can find Weaire-Phelan cell on the Internet, but it's very difficult to imagine a period without 3D model (and this is not only for me personally, I think :-)) 23:21 May 07 2021 Made poster high resolution 6Mpx https://cloud.mail.ru/public/6tsc/7MTdSSonB I hung a large one on the wall, it looks amazing! 13:43 Jul 16 2021 Made an attempt to parametrize the Kelvin cell in Grasshopper, I think successful. We wish you success in mastering new advanced techniques in 3D modeling! Lets start 3D printing the stuff! Love you!
