Dr. Lev Podshivalov, Prof. Anath Fischer and Prof. Pinhas Bar-Yoseph are working in collaboration with a research group led by Dr. Cynthia Gomes of the BAM Federal Institute for Materials Research and Testing in Berlin. The topic of their joint research is bone replacement parts from 3D printer.
This project was recently featured on German television.
Bone Replacement Parts from 3D Printer
Software controls construction of individualized parts
At the Federal Institute for Material Testing in Berlin, a method has been developed that will make it possible in the future for printers to create individualized pieces of bone for surgical use. This method requires a bioactive, regenerative ceramic material, a 3D printer for processing this ceramic material and software with which the porous structure of bone parts can be individually optimized on the basis of its sponge structure. Within a few years, this development may already be ready for use in dentistry.

The newest generation of ceramic material is resorbable bioceramics. This material can be broken down in the body and is also bio-active. This means that the material stimulates cell growth in the body, triggering repair mechanisms. This material is ideally suited for use in regenerative medicine. Recently, granules of this material have begun to be used in oral surgery, thus easily repairing damaged jaw bone within certain limits.
On this basis, the BAM Federal Institute for Materials Testing has now developed a new material for skeleton parts made of ceramic, suitable for use in 3D printers. To use this ceramic material, the 3D printers used for the project had to be modified because ceramic is not currently a common material. The biocompatibility and bioactive effect of the ceramic material must be tested for the approval process. To this end, the BAM is working with the University of Marburg, where the material is already being tested in animal experiments on mice, rats and sheep.
What is essential for the new process is the software that controls the layer structure of the ceramic material in the printer. Currently, in simulating the bone structure of hip joints, the so-called standard geometry is used — a grid modeled on the porous bone structure yielding only a very rough approximation. In contrast, according to the project’s manager, Dr. Cynthia Gomes of BAM, a porous sponge structure is used as the basis. With the help of special software developed by the cooperation partner, the Technion in Israel, it is also possible to modify this sponge structure with real computerized tomography data of the bone structure of patients. The bone fragments so produced are much more compatible to the human body.

29-31 January, 2013: CAD Lab hosts CAPER Consortium M18 Meeting
Prof. Moshe Shpitalni of the Faculty of Mechanical Engineering received the Society of Manufacturing Engineers’ 2013 Albert M. Sargent Progress Award. This award recognizes significant accomplishments in the field of manufacturing processes, methods or systems, and is awarded once a year for technical rather than management contributions. Prof. Shpitalni will receive the award at a formal black-tie gala, which will be held next summer in conjunction with the Society’s 2013 Annual Conference.
JUNE 2012: The CAD & LCE Laboratory in the Faculty of Mechanical Engineering at the Technion has become a partner in the MUPROD project, within the 7th Framework Programme of the European Commission.
MUPROD is an innovative quality control system to prevent the generation and the propagation of defects even before they generate manifest nonconformance
The project aims at developing an innovative Quality Control System that will drastically change the current concept of End of Line quality control, going beyond established methodologies such as Six-sigma and SPC. It will prevent the generation of defects within the process at the single-stage level and the propagation of defects between processes at the multi-stage system level. Application domains will include emerging strategic European sectors such as the production of electrical engines for sustainable mobility, large-part manufacturing for the wind power sector and the production of customized micro-intravascular catheters as high value medical products for the aging society.
The CAD & LCE Laboratory takes pride in joining the truly innovative vision of a manufacturing process that can be made free of defects by detecting and intervening on the defect root causes even before they generate manifest nonconformance. The Laboratory is responsible for developing new integrative and innovative techniques for integrating multi-scale, multi-resolution data provided by different sensors by means of data fusion methods that reconstruct 3D geometric models from the sampled data while utilizing multi-sensor technologies. To this end, hierarchical models and artificial cognitive systems will be developed that will represent the information provided by each sensor and by the network that controls the relations among the different sensors. The task’s ultimate goal is to demonstrate the advantages of applying data fusion on multi-sensor rather than on single-sensor data.
The CAD Laboratory will also be involved with identifying and developing synergetic process data gathering sensors and innovative inspection techniques for product inspection; developing monitoring and prognosis models based on different data analysis techniques (statistical, and cognitive systems) and predictive models at different levels (fixturing, process/machine, R&M, production, etc.); and disseminating the knowledge generated within the project. Activities such as workshops and seminars will be coordinated with the partners, and academic output of the project will be planned and monitored.
We are excited to be joining forces with the prestigious academic institutions, innovation centers and corporations partnering in the MUPROD Project.
