Simulating Additive Manufacturing – Optimizing quality, time & costs

Patrick Mehmert

by Patrick Mehmert, simufact engineering GmbH

A virtual “dry run” and prior optimization of manufacturing processes is already common in many industrial fields. Also in medical applications it can help to achieve better quality faster and less costly. This applies for single individual parts as well as for serial production. Current capabilities, benefits and open challenges of additive manufacturing simulation for medical applications are discussed.

Comparing biocompatibilities of 3D-printed absorbable metal implants

Holger Jahr

by Holger Jahr, Uniklinik RWTH Aachen

Additively manufactured absorbable porous metal implants possess promising mechanical and degradation properties in vitro and thus hold potential to meet various clinical applications. A reliable evaluation of these novel implants, however, requires an improved predictability of their biocompatibility and in vivo degradation characteristics from in vitro results. Current pre-clinical in vitro evaluation of medical devices still occurs under largely static culture conditions, while dynamic interstitial fluid flow regulates clearance of degradation products in vivo.

EU-funded project GIOTTO: The next challenge for smarT nanobiOmaterials and 3D technologies to treat osteoporotic fractures

Osteoporosis is a systemic, degenerative disorder affecting more than 200 million people in the world. In osteoporotic individuals, the density and quality of bones are reduced; this reduction occurs progressively and often without symptoms. As a result, bones become weak and the risk of fracture from a fall or, in serious cases, from minor trauma dramatically increases. These so-called fragility fractures decrease the quality and lifespan of affected patients. With progressive rise in life expectancy, osteoporosis is becoming a socio-economic challenge.

Individualized bone replacement parts by hybrid ceramic manufacturing

Recently, the innovative Freeze Foaming technique has been developed by Fraunhofer IKTS which allows producing an open cellular structure with a bimodal pore size distribution.

In in-vitro tests foams made of tricalciumphosphate and hydroxyapatite have been investigated with mice stem cells showing that the cells proliferate and start to differentiate and to form collagene structures. Now this method was combined with Vat Photo Polymerization (VPP) as an Additive Manufacturing technology for ceramic materials.

Nanofiber technologies for improving the biological compatibility of metal implants

by Marek Pokorny, Contipro a.s.

In the current project we deal with surface modification of implants for large joints, which are prepared by traditional and additive technologies. Czech private company Prospon s.r.o., material scientists from the Academy of Sciences of the Czech Republic, and we from private company Contipro a.s. as specialists in surface treatment of 3D surfaces with the help of an electrostatic field are involved in the project.

In my presentation I would like to draw attention to the importance of surface treatment of 3D implants intended for pharmacy. A surface layer of a metal implant affects its acceptance by the human body. The surface treatment enhances metal implant properties e.g. its biocompatibility, enhance a cell adhesion and proliferation, reduce inflammatory responses, and facilitate integration between the implant and surrounding tissues.

Voxel Printing for Surgery

Nicholas Jacobson

by Nicholas Jacobson, MIX Design

Voxel printing is the ability to vary material point by point across a 3d printed model. This allows us to better model changes in tissue and structure in fine detail. I will be showing our latest work using voxel printed model in the OR for Neurology, Hapatobiliary transplantation, and Cardiology. Finally I’ll be covering some of our latest custom tools for modeling and 3d printing.

3D Printing with High Perfomance Polymers for Implants and other Medical Products

stefan leonhardt

by Stefan Leonhardt, Kumovis

We at Kumovis developed a specialized 3d-printing system including clean-room technology. It is capable of processing high performance polymers like PEEK, PEKK, Ultem or PPSU. Furthermore, a special focus is set on degradable polymers.

At the conference we will present our technology and show results regarding achievable clean-room class inside our 3d-printing system. Also first clinical use-cases like using our technology for the lower jaw reconstruction will be presented.
