PRODUCT DEVELOPMENT

Additive manufacturing technologies offer a high degree of design freedom.


How lightweight this added value is achieved largely depends on the application. It may be a design through topology optimization, a performance enhancement through a function-oriented shape or the integration of multiple functions in a single structure.

  • Identification strategies to select the right components in serial products for an AM re-design
  • Understanding and supporting the paradigm shift from production-driven to function-driven design
  • Implementation of new technologies in the design process for the development of serial products

CARDAM product development teams can support the customer from the first conceptual drafts to the design and prototype preparation of a new, respectively innovated product.
Using AM allows us to design multifunctional components, unable to be manufactured by conventional technologies or such necessarily assembled from more parts. Reducing the number of parts in the final assemblies greatly contributes to the financial efficiency in production and assembly.
Materials used in AM achieve the strength characteristics of conventional materials commonly used in standard production.
Using topological optimization methods, we are able to propose a corresponding shape of the product and to increase the efficiency of material utilization, while satisfying all requirements on the strength characteristics of the concerned product. The significant added value of this optimized product is its low weight and strength.

MATHEMATICAL SIMULATIONS

Virtual models and mathematical simulations are a way to develop a new product without the use of time-consuming and costly experiments and unnecessary prototypes. Nowadays, computational methods are very sophisticated. We can simulate physical processes from the microstructure of materials, the behavior of an assembly based on the design assemblies all the way to the simulation of geophysical and atmospheric phenomena. We can simulate processes in gases, liquids, solid phases and non-standard states (such as plasma). It is possible to simulate the behavior of structures in physical fields, over a wide range of temperatures, the speed of events, etc. However, the main benefit of virtual simulation is the possibility of optimizing any parameters with the chosen target function (lifetime, strength, stiffness, natural frequency, heat dissipation, energy efficiency, material consumption, price …)
Computational simulations at the CARDAM, practically include all the possible capabilities of today’s computational methods. The orientation of the calculations corresponds to the focus of the company, i.e. the development of new products with a focus on the application of additive technologies. Logically the most used are the different types of optimizations. In particular topological optimization.

Strategies of computing simulations at CARDAM are based on several key pillars:

  • Validation of the correctness of calculations using experimental methods and laboratory measurements in cooperation with the Czech Academy of Sciences.
  • Using an own open system that allows to virtually use any specialized software. This approach allows avoiding the weaknesses of computing products, but it also to utilize their best features.
  • Compiling individual simulation steps into more general structures (networks), unlike the most commonly used sequencing procedures. These methods can eliminate the problem of using sequential analyzes when the weakest segment (analysis) reduces the grade of the entire computational chain.
  • Simulation of additive technologies enables the inclusion of the realistic properties of parts (made by additive technologies) into the optimization process and, especially, to minimize the costs of these parts.

Computational simulations at CARDAM are growing very dynamically, thanks to, in particular the close collaboration with nonprofit research institutes such as Universities and the Academy of Science.

ADVANCED MATERIAL DEVELOPMENT

Product features are often limited by conventional materials, traditional design methods and manufacturing technologies. These constrains can be overcome with comprehensive knowledge of materials, adopting mathematical simulations, topology optimization and additive manufacturing. It is CARDAM, where all those skills meet in one giving rise to a robust complex.

We are ready to develop high performance materials covering following applications:

  • Lightweight structures (lattice, honeycomb, topologically optimized, etc.)
  • Functionally anisotropic materials
  • Shock absorbing materials
  • Composites
