Organ Twins Reducing patient risk with 3D technology


With studies estimating the annual number of deaths due to medical errors in the hundreds of thousands, the time has come to revise the way the medical profession gains knowledge and experience. Advances in 3D printing technology and virtual simulation are creating new opportunities to improve the quality of treatments and patient safety. Biomodex is innovating in this area by developing sophisticated softwares and fabricating life-like human organs that can be used by medical students to learn and by doctors to practice surgical procedures before proceeding with a live operation. The 3DEXPERIENCE Lab is involved in this project providing Biomodex with access to its FabLab and with assistance using the Dassault Systèmes´ applications for organ design and for the manufacture of its first prototypes.

French startup advances healthcare safety with 3D-printed organs

Preventable medical errors are the No.3 killer in the U.S. causing the deaths of over 400,000 people every year. Whereas companies in other sectors have embraced 3D technology and simulation to optimize and predict real-life behavior, the medical industry has yet to fully take advantage of these advances relying more on cadavers, manikins and animals to advance the cause of healthcare. Yet these "old" methods pose ethical, cost and legal problems in many countries that prompt many to seek alternative solutions.


France-based Biomodex is using advanced software and 3D printers to fabricate life-like organs that can be used for medical training and pre-operative preparation. Using data obtained through organ imaging via an MRI or scanner, Biomodex developed a process that helps automate the creation of a virtual 3D model of that organ, which can then be printed using a 3D printer.


The areas Biomodex targets are:

  • Education: scanning the different organs of the body and providing medical students with a catalogue of virtual 3D models and 3D-printed organs to practice surgical procedures either through simulation or with life-like organs whose properties are similar to the real thing.
  • Pre-op preparation: by using MRI images or scans of a patient´s deficient organ to reproduce its exact twin, texture and thicknesses included, doctors will know what to expect and can perfect a surgical procedure before a live operation.
  • Medical device manufacturers: adding simulation and 3D printing capability to their implants makes their offering more attractive to practitioners as it increases first-time-right surgical success.


Biomodex ensures healthy lives and promote well-being for all at all ages.  Their invention will help improve health care safety by enabling practitioners and medical students to acquire knowledge and experience without putting patients at risk.



Meet the team

Founded by Thomas Marchand, business school graduate and Sidarth Radjou, engineer, Paris-based Biomedical Modeling Expertise, or Biomodex, covers the entire surgical value chain from raw patient data derived from CT scans or MRI to the manufacture of high-quality 3D-printed organs. The company closely works with medical experts to ensure that their models faithfully represent the characteristics of each organ.

Biomodex was selected by the 3DEXPERIENCE Lab because of the innovative potential of its solutions for billions of people around the world. Dassault Systèmes supports Biomodex providing it with Cloud access to its design and simulation software and helping it transition to this environment. It also created a community on the 3DEXPERIENCE platform to facilitate interaction and the exchange of ideas between project members, medical experts and people passionate about this technology. The 3DEXPERIENCE Lab also proposes mentoring and training sessions to help Biomodex engineers use its solutions in the best way. The 3DEXPERIENCE Lab was involved throughout the entire value chain from generating a cloud of points, to constructing the 3D virtual model, and during simulations to test material resistance and zones where the organ is most fragile. Biomodex also has at its disposal a dedicated space on the 3DS campus with a FabLab and 3D printers to prototype their designs. The Lab´s help to industrialize the entire process saved Biomodex considerable time.
