In addition, the experts will be showing the professional audience processes to laser weld plastics for medical components without leaving welding seams as well as to laser polish metal.

At the IVAM joint stand H 19.1 in Hall 8a at this year’s Compamed (in Dusseldorf, Nov. 17 to 19, 2010), the Fraunhofer ILT is presenting tailor-made biodegradable implants. They were produced using Selective Laser Melting (SLM), an additive laser manufacturing process. Thanks to their interconnective pore system, these implants made of β-tricalcium phosphate enhance stromal and vascular cells’ ingrowth ability. In addition, porous implants made of a titanium alloy, manufactured using SLM, will be shown.
Another area where lasers can be used in medical technology is the polishing of metal. In this case, the laser beam melts the material surface to a depth of about 5 microns. The surface tension ensures that the fluid metal flows evenly and dries smoothed. This process developed by Fraunhofer ILT is interesting for all medical-technical components with metallic surfaces that need to have an extremely low roughness. Manufacturers can see examples of such components at the IVAM stand.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
