A short story of biomaterials
April 2024

The materials which have been employed throughout human history have defined its progress. The designation of civilizational ages—the stone age, bronze age, iron age, cement age, steel age, silicon era and nowadays, the age of new materials—effectively highlights the significance of materials. Considering our society both today and in the future, new materials are needed in every technical discipline, and the biomedical field does not differ.

Although biomaterials have been around for a very long time, the name and notion of biomaterials are relatively recent. A biomaterial is any substance that can be injected into a living organism or body without causing a detrimental biological reaction. The historical use of biomaterials dates back to ancient times; for instance, ancient Egyptians utilized animal sinew for sutures to stitch wounds.

The field of biomaterials has undergone a significant revolution by embracing a multidisciplinary approach that integrates various scientific disciplines, including medicine, biology, physics, chemistry, materials science, manufacturing engineering, and tissue engineering. Over the past few decades, this field has experienced substantial growth, driven by noteworthy discoveries in tissue engineering and regenerative medicine, which have been successfully translated into advancements in medical device manufacturing.

These days, they are incredibly popular in the medical industry for a variety of uses, from sutures to permanent implants. Before people could understand what a biomaterial was or why they worked or did not function, they used them for many years to give solution to medical problems. Except from some materials used externally, no medical device firms produced biomaterials for a long time, and materials were not created with the intention of employing them as biomaterials. This indicates that there were conflicting findings on the safety and effectiveness of the materials, and that there were no rules or guidelines to adhere to while utilizing them in the human body.

The first biomaterials were simple, readily reusable materials that could be found in nature. There was evidence of the use of seashells as dental implants, as well as sutures made of linen or catgut. In addition, certain tribes of people healed wounds with the jaws of huge ants rather than sutures. The biomaterials used in medical operations evolved together with technology and material processing. The development of stronger devices, like metal sutures and various implants (including dental implants) was made possible by the use of metals as biomaterials. As these metals were utilized for longer periods of time as biomaterials, concerns about some of them emerged, giving rise to the idea of biocompatibility. After undergoing extensive testing, a some of these metals were retained for use as biomaterials and others were rejected because of their harmful effects on the body. With the eventual development of plastics, biomaterials with a great range of qualities were made suitable to be used to create medical devices. It is currently routine practice to test the biocompatibility of polymeric biomaterials. Novel biomaterials, such as hydrogel, are continuously being developed and examined for various uses. More innovative concepts in the field of biomaterials are introduced by hydrogels, which are polymers that swell in water but do not dissolve in it. The bioceramics industry saw numerous breakthroughs and developments during its heyday in the 1980s and 1990s. In this century of considerable interest in tissue engineering and regenerative medicine, biodegradable bioceramics are proven to be very helpful for hard tissue regeneration. Composite biomaterials are just as important in the biomedical industry. A wide range of biological uses has been invented, including drug delivery systems, biosensors, bioseparation, and human tissue regeneration.

In this sense, a biomaterial for a medical device can be made from metals, ceramics, polymers, glass, and even natural tissues. A wide range of medical devices, including bone plates, screws, orthopaedical and dental implants, heart valves, contact lenses, coronary stents, and coatings and textiles, can be made from these materials.

3D printers in medicine (2)
March 2024

It's amazing! Two difficult surgeries were performed at the Poznan Hospital using 3D technology. They allowed to provide a treatment of tear duct obstruction. The application of augmented reality enabled to do endoscopic sac-nasal anastomosis. The surgeon had the opportunity to observe and superimpose a 3D reconstruction image on the actual image of the operated area using special holographic glasses. Thanks to it, the operation could be more precise than a standard one using two-dimensional imaging, i.e. computed tomography.So far, only 3 such operations have been performed in Poland (in Warsaw), so we are glad that other centers undertake such actions for the benefit of patients. Congratulations!

3D printers in medicine
Febuary 2024

Do you still wonder if 3D printers and medicine are related? We are pleased to inform you that a complex maxillofacial surgery procedure was performed at the Poznan Hospital! Thanks to the cooperation with the Poznan University of Technology, the treatment of a patient with temporomandibular joint stiffness was provided. The quality of life of a person after radiotherapy who had difficulty opening his mouth has been improved significantly. It was possible due to changing position of the mandible, which, as you probably remember, is the only movable bone in our head. We wish the team a lot of success and a patient a quick and easy recovery! We would like to remind you that our project supports activities related to the use of 3D design in medicine, and ergonomics!

Our new paper
October 2023

Have you already read our new paper entitled: “File Formats and Digital Data Transfer for Dental Needs” (Diana Pavlova, Tihomir Dovramadjiev, Dimo Daskalov, Rozalina Dimova, and Beata Mrugalska) published in Lectures Notes in Networks and Systems?

Abstract: The use of CAD/CAM in dentistry makes it possible to optimize the treatment process in case of a violation of parts of the orofacial complex. It contributes to the rationalization of the production process of the dental prosthetic structure by transferring file formats between different software programs for design, design visualization, simulation, and post-production through an additive or subtractive process. This electronic process has the ability to store larger amounts of medical data with different formats and transfer them between different software.

The necessity of 3D CAD software
in biomedical technology
April 2023

The medical device manufacturing industry is growing rapidly in order to keep up with the increased demand. Therefore, medical device product designers must create innovative medical products. Plenty of challenges are to be considered during the manufacturing of medical equipment, with the most important among them being patient safety. Efficiency, effectiveness, and cost containment, are also very important to be considered.

Therefore, the use of 3D CAD software in biomedical technology is necessary.3D CAD is a three-dimensional computer-aided design tool used by designers, engineers, and architects to create industrial objects that include complex mechanisms.It helps to create functional, virtual prototypes of three-dimensional designs.CAD software can be very specific, whether it is for industrial, mechanical, architectural, or aeronautical engineering design.

CAD software tools allow designers to investigate design ideas, modify designs easily, visualize concepts through renderings, simulate how a design performs in the real world, and draft documentation. Moreover, using cad software designers can share designs for feedback, and allow companies to get to market faster. In the biomedical field, CAD software is used for accurate modeling of complex geometries, customization, and patient-specific solutions, iterative design processes, simulation and analysis, collaboration, and communication, as well as facilitating manufacturing and production. More specifically CAD is necessary for the following reasons:

  1. Precise Design: Biomedical technology often involves intricate and complex designs, such as medical devices, implants, and prosthetics. CAD software allows engineers and designers to create precise and detailed 3D models of these components. It enables accurate representation of complex geometries, dimensions, and specifications, ensuring the design meets the required standards and functional requirements.
  2. Visualization and Simulation: CAD software provides visualization tools that allow designers to see the virtual representation of their designs in 3D. This visual feedback helps in assessing the aesthetics, ergonomics, and functionality of biomedical devices. Additionally, CAD software often includes simulation capabilities, allowing engineers to test the performance and behavior of the devices under different conditions. This simulation helps identify potential design issues and optimize the performance before physical prototyping.
  3. Customization and Personalization: Biomedical technology often requires customized and patient-specific solutions. CAD software enables the creation of personalized designs based on patient data, such as medical imaging scans. With CAD, engineers can precisely model and modify the design to fit the unique anatomy and needs of individual patients. This customization enhances the effectiveness and comfort of biomedical devices, leading to improved patient outcomes.
  4. Iterative Design Process: CAD software supports an iterative design process, where designers can make changes and refinements to their designs based on feedback and testing. The software allows for easy modification of design parameters, enabling rapid prototyping and evaluation of design iterations. This iterative approach leads to the development of optimized and efficient biomedical devices.
  5. Collaboration and Documentation: CAD software facilitates collaboration among multidisciplinary teams involved in biomedical technology development. It allows for the sharing and exchange of design files, enabling effective communication and feedback from clinicians, researchers, and manufacturers. Additionally, CAD software enables the creation of comprehensive design documentation, including detailed specifications, measurements, and material information. This documentation is essential for regulatory compliance, manufacturing, and quality control.
  6. Integration with Manufacturing Technologies: CAD software plays a crucial role in the integration of design with manufacturing technologies in biomedical engineering. The CAD models generated using the software can be directly used in various manufacturing processes, including additive manufacturing (3D printing), CNC machining, and mold fabrication. This integration ensures accuracy and consistency between the designed model and the manufactured product.

Overall, CAD is necessary in biomedical technology for precise design, visualization and simulation, customization and personalization, iterative design processes, collaboration and documentation, and integration with manufacturing technologies. It enhances the efficiency, accuracy, and innovation in the development of biomedical devices, leading to improved healthcare outcomes.

Popularization of surgery
with the use of 3D implants
March 2023

In recent days, information has appeared in the Polish media about an operation performed in Poznań with the use of an endoprosthesis produced with the use of 3D printing.

The operated person, suffering from many different diseases, has not been able to take a step for the last year. It was caused by a defect in the pelvic bone, as a result of moving around for many years with too loose an endoprosthesis. Now, after implanting an implant that takes into account the anatomy of that person, the patient can walk again (


The use of implants can be also a therapy for people after oncological treatment, when the cancer attacks the bones and they need to be removed. In large cavities, a typical implant cannot be used - it must be made specifically for a specific patient. Precise specification is necessary before the procedure, using, among others, computed tomography and magnetic resonance imaging. Only then the implantsare printed (,244844.html).

At present, in Poland, endoprostheses made in 3D technology are implanted only in a small group of patients. The problem is particularly important because each of us is different and tailor-made prostheses are the future!For comparison, specialists from the City Hospital. J. Strusia in Poznań install approx. 500 mass-produced hip and knee endoprostheses annually. 3D printing gives a chance to treat those patients who were previously unqualified for it. In recent years, only 3 such procedures have been performed in Poland (,200562.html).

The ErgoDesign project aims to support the development of specialists in this field, to make this therapy more accessible by educating more specialists in the field of bioengineering and biomechanics. Not only in Poland, but all over Europe!

Additive technologies
are on the rise in today's world
Febuary 2023

Additive technologies are on the rise in today's world. 3D printing has appeared in almost all areas of industry and life, allowing the rapid creation of unique pieces. Additive technology is also playing a role in medical technology, with dental technology being the fastest growing. In the production of dental implants, each piece is unique, because each tooth is individual, like a fingerprint. Several methods can be used to produce the implant, which is the result of careful condition assessment, design and manufacture.
