The introduction of additive technologies to various industries determined the transition to a fundamentally new approach for designing and creating the best-in-class products. This new approach is bionic design, when received the best engineering solutions (parts, products, structures, etc.) resemble the structures found in nature.
We also use hollow microporous structure (lattice structures). Manufacture of lattice structures using additive technology reduces the weight of the end products while maintaining or improving the mechanical properties.
Symbiosis of additive manufacturing with topological optimization will implement the original solutions of engineers and designers, taking into account the requirements of the structural integrity and strength of structures.
The bionic design made by computer simulation technology of the structures behavior in various modes to conduct virtual tests on the cyclic loading, static and dynamic loads. Understanding the capabilities of different 3D-printing technology (SLS, SLM, EBM, LaserCUSING, DMLS, SLA, FDM, etc.) allows to create the optimal structures, taking into account the cost of product production and operation.
The transition from the traditional production methods to the additive technologies can give the producer a lot of quality advantages: the ability to manufacture complex parts with complex shapes with different internal structures, reduction of manual labor, reducing the number of process steps, reducing material consumption, and as a result, accelerated and cheaper manufacturing process.
We perform adaptation to 3D-printing, this process includes:
The development of new design and technological solutions (parts and components, structural elements, reverse engineering) is based on the computer simulation. Based on the information about the product’s functional purpose operating conditions and the anticipated appearance (industrial design) are developed. Then the dimensional model and the matrix of target values follow. Based on the operating conditions we determine the load conditions, then set the optimum criteria (objective functions), for example, minimum weight, and restrictions on the variables. We use the technology of the virtual finite element modeling, analysis and simulation of physical processes for the design of structures subject to operating conditions and life-cycle cost (ABAQUS, ANSYS, LS-Dyna, MSC Nastran, etc.). On the basis of these results we evaluate the structure condition during operation and set the direction of future multi-criteria optimization.
The use of additive technologies, as well as modern design and simulation technology of physical processes to optimize the production process and to transfer most of the technological chain of production in the virtual space, while minimizing labor costs. To make this transition is necessary to "unpack" the production chain, which is used now. We will estimate, for which the details in your process chain advisable to use additive manufacturing, select the print technology, equipment, advise on the introduction of the additive section in the overall production process, make optimization based on the capabilities and limitations of additive technologies and a common process.
