3D Printing in the medical sector

Bild: 3D Druck in der Medizin

In the medical sector, previously unimaginable applications have emerged through additive manufacturing (3D printing) in the recent years. Developing solutions becomes a whole new process, reconsidered and implemented free of geometries. Offering reliable, easy-to-use and economic production systems for users in the medical technology sector, German RepRap (GRR) has the machines to open up new business models. Patient-specific products (such as prostheses) as well as future-oriented research areas are focused. Every part that is used in the medical sector is subject to strict certification. Furthermore the whole production process, the material as well as the technology that is used are subjected to precise certification before any application is approved.

Basically, 3D printing offers a variety of advantages that makes it particularly attractive compared to other manufacturing processes for the medical sector. It enables a faster product launch by shortening test periods in the prototyping area and is used in areas of surgery, dental technology or orthopedics. As an established provider of 3D printing solutions, GermanRepRap GmbH has successfully implemented numerous projects and will happily support you to benefit from that experience.

Requirements of the medical sector

Working in the medical sector is literally a matter of life and death. Minor defects in production or material can have long-term consequences for patient health. The requirements for 3D printing in the medical sector are correspondingly high:

  • Individual adaptability and flexibility
  • Reproduction of complex shapes and structures
  • High accuracy
  • Low fault tolerance
  • Stability and durability
These are just a few of the numerous requirements that products for the medical sector have to achieve. They originate from areas such as drug testing in the pharmaceutical industry, orthopedic applications for patients or the custom-fit and ergonomic manufacture of safety equipment (e.g. bicycle helmets).

Additive manufacturing Innovation: 3D components out of liquid silicone for the medical sector and orthopedic technology

The world's first system to 3D print components out of liquid silicone is the German RepRap L320. The L320 is an industrial system that combines component-specific process parameters that are required by customers and the technical equipment for the process in one machine.

Nowadays 3D printing is used in several fields such as smaller regional companies, practices, laboratories or various industrial areas. Individual tailored auxiliary processes for customers and patients can easily be implemented using additive manufactured solutions. German RepRap has a system solution for any application.

Our latest innovation: Liquid Additive Manufacturing (LAM). To manufacture 3D components out of liquid silicone with the LAM process is a real innovation developed by German RepRap. Silicone is a very widely used material in the medical sector. The main advantages are obvious:

  1. The human body does not recognize silicone as a foreign material.
  2. Not being adherent it can be shaped into almost any imaginable geometry.

Our L320 system solution includes the complete printing system as well as the unique LAM process for the process-reliable construction of components out of liquid silicone.



The industrial printer L320 scores particularly when it comes to silicone materials that are often used in the medical sector (e.g. SilasticTM 3D 3335). The structural setup and accurate thermal cross linking of the LAM are convincing all along the line. You don't think your business would benefit of it? Find out more about the possibilities of printing liquid silicone.

Other common materials in the medical sector

Materials made of plastic or silicone are particularly popular for 3D printing in the medical sector. For example, the classic ABS filament is mainly used for simple printing processes due to its comparably low price. The most common materials used in the professional medical sector are (depending on the successful certification process):

  • DuPont™ Zytel 3D12G30FL BK309
  • DuPont™ Zytel 3D10CF20FL BK544
  • PEEK
  • Performance PLA
  • PEI
  • PEKK
  • PET-G
  • TPU 93
  • TPU 64D
  • SILASTIC 3D 3335

ABS and PEKK are plastic filaments that have favorable properties for 3D printing. Technically very robust and temperature-resistant components can be manufactured with these materials. With a temperature resistance of up to 290 °C PEKK is an particularly interesting material for the medical sector. In various sterilization processes it is asked for requirements of certain temperature resistance. The main crucial factor for additive manufactured components is to have at least the same good material properties.

Covering the various appropriate requirements all 3D systems from German RepRap meet the highest standards of quality and reliability in professional production. In addition, our systems also convince with their economic efficiency. Convince yourself and contact us!

"The x350 Pro 3D printer is already fully integrated into everyday life and has become a completely normal work device. […] Often the machine prints overnight and sometimes we actually need a second 3D printer to handle all the orders."

Achim Oberle, managing director of the Oberle shoe company, about the long-term 3D printing collaboration for the orthopedic shoe technology project.

Beispiel 3D Druckerzeugnis für die Medizin

In the case of the Oberle shoe company, our German RepRap x350pro 3D printer is used. Everything that it takes for the customer Oberle shoes to be successful in 3D printing, is provided by GRR. The x350pro 3D printer is optimally suited for the production of different foot shapes in the orthopedic shoe technology. The printing system enables the individual production of soles for shoes. With additive manufacturing the customer was able to shorten processes and waiting times.

The Oberle shoe company discovered a whole a new business area very early by using additive manufacturing in cooperation with GRR. The Oberle shoe company produces healthy shoes.
