Researchers at these universities believe that they can work on the internal structures of bones to produce strong 3D printed materials that can be used in homes and building structures.
Pablo Zavattieri of Purdue University said, ÔÇťThe structures have columns carrying the majority of the load and beams connecting the columns. From these materials, we can learn to create more powerful 3D printed materials for buildings and other structures. ÔÇŁ
Researchers have discovered that these ‘beams’ in the bones contain more rigidity and strength than previously known. These beams are also known as ‘trabecula’. In the article published in the National Academy of Science, it was said that the horizontal abutments in the bone prolong the fatigue time of the bone.
Researchers believe that 3D printed building materials designed with similar interior structures can be used to build more durable buildings. The researchers tested the accuracy of these theories in Zavattieri’s laboratory by designing a 3D printed polymer with a trabecule-like structure.
The mechanical analysis simulation found that thicker horizontal abutments allow the polymer to remain under load longer. The reason for this is that the thickness of the abutments does not significantly increase the mass of the polymer. The team said that bone-inspired polymers can be used to produce more flexible and lighter construction materials, which are key to building 3D printed houses and structures.
