Copper3D ( is a chilean and US based company born in an academic process in the Master of Innovation at the Adolfo Ibáñez University, the most important business school in LatAm. In this academic program, the founding team of this company met:
Andrés Acuña, Electronic Civil Engineer and MSc. in Innovation, with 14 years of experience in the mining sector and specializations in automation of mineral processing.
Daniel Martínez, Physical Therapist, MBA and MSc. in Innovation, with a vast experience in management, marketing, innovation and new business models in the Healthcare industry.
Claudio Soto MD, Physician and MSc. in Innovation with experience in rehabilitation, regulatory issues in Health and management in large healthcare institutions.
During the Master’s program we were developing small-scale innovation projects always in the areas of Health and Technology (the big issues that we are passionate about) until we come to a big problem / challenge to be solved in the world of Healthcare and Rehabilitation.
We realized that more than 40% of amputees suffer some type of dermic disorders due to the use of their prostheses. This phenomenon is also observed in non-amputee patients who use orthoses.
The reasons? The complex geometries of these medical devices (so difficult to clean properly) and the high bacterial burden present in these devices, which in contact with the skin can cause dermatitis, folliculitis, fungal or bacterial infections, among others.
But then we realized that the problem of bacterial burden is much more complex and huge: According to some studies, about 50% of all HAI’s (Hospital Acquired Infections) worldwide are due to the bacterial burden of medical devices that are difficult to mantain clean and sterilyzed.
After a long process of research, development and innovation, we realized that the ideal solution to this problem involved the molecular intervention of the material with which these medical devices are manufactured. After discarding many options, we began prototyping a new polymer for 3D printing with an internationally patented additive containing copper nanoparticles, extremely effective in eliminating fungi, viruses and bacteria but safe for humans at the right concentrations. After the successful preliminary trials in Chile, we decided to start with the industrial manufacture of this material in Europe for later commercialization.
At the moment we have our first product available, it is a high quality antimicrobial PLA polymer with additive concentration of %, it is called PLACTIVE since it is a PLA polymer with “active” properties in the elimination of a wide range of microorganisms. We also developed a medical grade material called NANOCLEAN, which is a high quality antimicrobial PETG polymer aimed at more specific purposes in the world of medical devices, and a third product of the portfolio is MDflex, a flexible TPU based filament, also with full antimicrobial action. Our 3D printing materials and devices 3D printed with our material, have been studied and validated as fully antimicrobial by the Microbiology Laboratory of the Universidad Católica de Valparaíso, Chile and the laboratory SITU Biosciences in USA. PLACTIVE was also clinically tested in 3D printed prosthetics for US war veterans, study published in the Journal of Applied Sciences, and is currently being tested by NASA for 3D printed space applications:
We strongly believe in the impact that hard work, a great team and new technologies have on the quality of life of people, and in the power of innovation to reshape the future.
