Special Issue Information

Dear Colleagues,

Since the creation of this Universe, Nature has developed its own unique advanced materials and structures which inspire designers for developing next-generation materials with excellent mechanical, hydrodynamic, optical, and electrical properties. The art of developing materials/processes/designs inspired by Nature (biomimetics) combined with next-generation additive manufacturing processes may create a paradigm shift in modern materials science and technology. Additive manufacturing (3D printing), with its ability to create design without any theoretical restrictions, has opened doors for manipulating and mimicking the intrinsically complex multiscale/multifunctional structures and multimaterials that are abundantly found in Nature. This Special Issue focuses on the recent developments in the area of biomimetic additive manufacturing. The combination of inspiration from various organisms (e.g., lobster claws, pine cones, flowers, octopuses, butterfly wings, etc.) with the potential of 3D-printing technology will be the focus of this Special Issue. Future opportunities and difficulties in the field of biomimetic additive manufacturing may be discussed.

Scientific contributions are invited from scientists, researchers, engineers, and industry professionals to disseminate recent inventions and developments in the field of biomimetics and advanced manufacturing processes. The potential topics include but are not limited to:

  • Biomimetic materials;
  • Biomimetic additive manufacturing processes;
  • Biomimetic design for additive manufacturing;
  • 4D biomimetic printing;
  • Biomimetics with added functionalities;
  • Next-generation biomimetic parts;
  • Opportunities in biomimetic additive manufacturing;
  • Difficulties in biomimetic additive manufacturing;
  • Standardization of biomimetic additive manufacturing.

This Special Issue looks forward to receiving submissions in any form, including review articles, regular research articles, and short communications. Both experimental and theoretical studies are of interest.

The topology optimization (TO) process has the objective to structurally optimize products in various industries, such as in biomechanical engineering. Additive manufacturing facilitates this procedure and enables the utility of advanced structures in order to achieve the optimal product design. Currently, orthopedic implants are fabricated from metal or metal alloys with totally solid structure to withstand the applied loads; nevertheless, such a practice reduces the compatibility with human tissues and increases the manufacturing cost as more feedstock material is needed. This article investigates the possibility of applying bioinspired lattice structures (cellular materials) in order to topologically optimize an orthopedic hip implant, made of Inconel 718 superalloy. Lattice structures enable topology optimization of an object by reducing its weight and increasing its porosity without compromising its mechanical behavior. Specifically, three different bioinspired advanced lattice structures were investigated through finite element analysis (FEA) under in vivo loading. Furthermore, the regions with lattice structure were optimized through functional gradation of the cellular material. Results have shown that optimal design of hip implant geometry, in terms of stress behavior, was achieved through functionally graded lattice structures and the hip implant is capable of withstanding up to two times the in vivo loads, suggesting that this design is a suitable and effective replacement for a solid implant.

Biomimetics is an emerging field of science that adapts the working principles from nature to fine-tune the engineering design aspects to mimic biological structure and functions. The application mainly focuses on the development of medical implants for hard and soft tissue replacements. Additive manufacturing or 3D printing is an established processing norm with a superior resolution and control over process parameters than conventional methods and has allowed the incessant amalgamation of biomimetics into material manufacturing, thereby improving the adaptation of biomaterials and implants into the human body. The conventional manufacturing practices had design restrictions that prevented mimicking the natural architecture of human tissues into material manufacturing. However, with additive manufacturing, the material construction happens layer-by-layer over multiple axes simultaneously, thus enabling finer control over material placement, thereby overcoming the design challenge that prevented developing complex human architectures. This review substantiates the dexterity of additive manufacturing in utilizing biomimetics to 3D print ceramic, polymer, and metal implants with excellent resemblance to natural tissue. It also cites some clinical references of experimental and commercial approaches employing biomimetic 3D printing of implants. Full article
