Teaching Innovation

“CDIO” IN MECHANICAL AND BIOMEDICAL ENGINEERING

According to our experience, the graduates and post-graduates from multidisciplinary engineering programmes, including Industrial and Mechanical Engineering, can play varied and very relevant roles in several industries (including transport, energy, health and aerospace) and in extremely complex product development projects. We carry out teaching-learning experiences in several subjects and UPM programmes linked to Industrial, Mechanical and Biomedical Engineering, including: “Engineering Design” and “Bioengineering Design” in the Master’s Degree in Industrial Engineering, “Bioengineering” in the Master’s Degree in Mechanical Engineering, “Machine Design” in the Bachelor’s Degree in Industrial Technologies and “Development of Medical Devices” in the Bachelor’s Degree in Biomedical Engineering. We incorporate research results into the different subjects and try to promote project-based learning following the CDIO (conceive-design-implement-operate) approach, enabling students to live through the complete development process of novel innovative engineering systems and products.

Promotion of Science, Technology & Society approaches

Science and Technology are part of every branch of modern life and fundamental for the future and sustainability of Society. At the same time, only in intimate contact with the needs and problems of people can we drive the scientific-technological advances towards the adequate directions, aimed at building a more harmonic global civilization with healthier societies. In consequence, as part of our research, we focus on the application of our experience and resources to objects connected with our every-day life, focusing on the needs of people and trying to attract talent for building together the future of Science, Technology and Society, which is linked to the promotion of scientific-technological vocations. Among the more relevant aspects, in which we focus, it is important to cite:

  • Attendance to and organization of events for promoting scientific-technological vocations.
  • Scientific divulgation videos, reports and events on product design.
  • Scientific divulgation videos, reports and events on additive manufacturing.

Surface design and functionalization of materials and products

Material (and device) surface topography has a direct influence on several relevant properties, linked to its final performance, such as friction coefficient, wear resistance, self-cleaning ability, biocompatibility, optical response and properties, touch perception, overall aesthetic aspect and even flavor. Therefore it also plays a determinant role in material selection in engineering design, especially in the field of micro- and nano-system development, in which the effects of topography on the incorporation of advanced properties are even more remarkable. The possibility of manufacturing textured materials and devices, with surface properties controlled from the design stage, instead of being the result of machining processes or chemical attacks, is a key factor for the incorporation of advanced functionalities to a wide set of micro and nanosystems. In our lab, high-precision additive manufacturing technologies based on photo-polymerization, together with the use of fractal and math-based models linked to computer-aided design tools, allow us to precisely define and control of final surface properties. In this fascinating field of research and development, we usually dedicate our efforts to the following topics:

  • Design of bioinspired surfaces based on math-based approaches.
  • Control of surface topography and micro-texture from the design stage.
  • Design and development of hydrophobic / hydrophilic patterns for enhanced tribology.
  • Incorporation of desired surface properties to final applications.
  • Improved ergonomics, aesthetics, optical properties and contact phenomena.

Knowledge-based design of complex geometries for improved functionality

viii) Knowledge-based design of complex geometries for improved functionality

Additive manufacturing technologies, by working on a layer-by-layer approach, enable solid free-form manufacture and the production of materials, devices and products with complex geometries impossible to obtain otherwise. Geometrical complexity can be used to integrate several functions in a single part, to optimize the number of components of engineering systems and to reduce the manufacturing steps involved in mass-production. Such geometrical complexity is also interesting for the promotion of biomimetic designs, for improving ergonomics and for enhancing mechanical, dynamical, thermal and fluidic functionalities following bioinspired design strategies and other theories for the generation of innovative and efficient designs, such as the constructal law. At the same time, geometrical complexity is inherent to topological optimization and to other optimization procedures aimed at minimizing material consumption and maximizing certain functionalities per mass unit. As regards the design and tool-less manufacture of complex geometries, we are actively working in research and development lines including:

  • Design of bioinspired support structures for eco-efficient additive manufacture.
  • Design and application of lattice and porous structures for developing metamaterials
  • Design and application of complex geometries for special properties (i.e. auxetics).
  • Design and application of lattice and porous geometries for efficient product development.
  • Design and application of complex geometries for efficient product development.
  • Topological optimization procedures towards improved resistance vs. weight.
  • Topological optimization procedures towards improved mass distributions.

Mechanical Engineering Department, ETSI Industriales,
Universidad Politécnica de Madrid (UPM)

ABOUT US
The Product Development Lab was founded at Universidad Politécnica de Madrid in 1997 by Chair Prof. Pilar Lafont as the first digital design and manufacturing “fab-lab” in our university and the first one to count with a high-performance industrial additive manufacturing laser stereolithography system in Spain. Since then, a group of passionate researchers and teachers from the Mechanical Engineering Department at the ETSI Industriales of the Universidad Politécnica de Madrid (Industriales UPM) work together for reshaping product development and for setting the foundations towards the future of Engineering and Product Design.

Consequently, the UPM’s Product Development Lab is pioneer in our country in the fields of computer-aided design, engineering and manufacturing, as well as in the use of rapid prototyping and additive manufacturing technologies (commonly referred to as 3D printing technologies) for the development of prototypes and final products with complex geometries, high level of detail and using polymeric, ceramic, metallic and composite materials.

We aim:

“To promote the development of innovative products in all kinds of industries by the systematic application of advanced design, engineering and manufacturing technologies and by taking advantage of the use of modern materials”.

“To help enterprises, technological centers and researchers to improve their products by including special functionalities and by design optimization strategies”.

We seek to jointly employ systematic product development methodologies, advanced design and manufacturing technologies and innovative testing procedures for the straight-forward development of advanced products within several industries, including health, energy, transport and space, among others, for the benefit of Society.

In addition, we expect to prepare our students for the future of Engineering, which will for sure benefit from the progressive incorporation of Mechanical Engineering principles to the aforementioned systematic methodologies and from the combined use of multi-disciplinary design/modelling tools and additive manufacturing technologies, towards advanced engineering systems with enhanced performance. Innovative project-based learning methodologies, based on the CDIO (“conceive-design-implement-operate”) approach, are fundamental for the desired shift and allow us to incorporate research results into daily lessons.

Main lines of research, innovation and translation for the Product Development Lab at UPM initiative include:

We collaborate with technological and academic institutions worldwide, as well as with enterprises and foundations devoted to product development in all Engineering areas. We are also promoting collaborative open source co-design strategies for the development of new solutions to face the current and future global challenges.

Knowledge-based design of multifunctional / advanced materials

Numerous active, multipurpose or “smart” materials have appeared in recent decades, all capable of responding in a controllable way to different external physical and chemical stimuli by changing some of their properties. These materials can be used to design sensors, actuators and multipurpose systems. In addition, special “metamaterials” are designed to obtain desired properties by means of adequately defining and controlling their microstructure. All these materials can be considered “knowledge-based”(for the special design requirements involved in their selection and application) and “multifunctional” (for their unique properties connecting different domains of Physics and Chemistry) materials. Since 2012 we actively collaborate with the “European Virtual Institute on Knowledge-Based Multifunctional Materials” (KMM-VIN) (http://kmmvin.eu), especially in tasks linked to materials modelling and to biomedical applications of innovative biomaterials, having hosted its 5th Industrial Workshop on “Multi-scale and multi-physics materials modelling for advanced industries”.

Among the activities we perform linked to knowledge-based multifunctional & advanced materials, mainly focused to smart materials and mechanical metamaterials, we highlight:
– Knowledge-based design of smart materials & metamaterials.
– Characterization, modelling and simulation of smart materials & metamaterials.
– Industrial applications of smart materials & metamaterials.
– Manufacture of smart materials & metamaterials and of applications based on them.

Innovative composite and nano-composite materials for advanced industries

Composite materials are fundamental in modern product development, as they help to enhance the performance of engineering systems, enabling special mechanical properties, electrical responses, thermal behavior and typically optimizing overall weight. Traditional fiber-reinforced polymers perform at par with special and expensive alloys. Resins functionalized with nano-particles promote special mechanical, thermal, electrical, optical and even self-sensing and piezo-chromic effects. Multi-layered materials combine structural stability with impact resistance, even performing as complex organic biomaterials. Lattices with knitted electrically conductive or reinforcing fibers enable “smart” composites with actuation capabilities or with improved biological response. Some fields of research linked to composites and nano-composites, to which we devote efforts include:

  • 3D printed resins with nano-fillers for improved product functionalities.
  • Self-sensing composites and nano-composites for smart engineering systems.
  • Smart shape-memory composites for electro-thermo-mechanical coupling in smart systems.
  • Composite tissue engineering scaffolds for biomimetic response in articular repair.
  • Characterization and modelling of composite and nano-composite materials.
  • Industrial applications of composite and nano-composite materials.
