MATERIALS: Putnam Plastics introduces pad printed PEEK and thermoset polyimide extrusions for high performance catheter applications. These pad printed components utilize the company’s internally developed pre-treatment technologies including the application of plasma.Pad printing is frequently used to print graphics on the exterior surfaces of minimally invasive medical devices. These graphics serve critical functions including product identification, location and orientation during surgical procedures.
PEEK and thermoset polyimide polymers are increasingly being used for minimally invasive applications due to inherent strength and chemical resistance properties. These same material properties create greater challenges for pad printing. While plasma pre-treatment increases ink adhesion on all plastics, it is of greatest value when used on polymers inherently resistant to thermal and chemical degradation such as PEEK and thermoset polyimide.
When compared to other methods of improving bonding, Putnam’s plasma pre-treatment involves little to no heat transfer into the polymer component, preserving its mechanical dimensions and properties. It involves no toxic chemicals, generates no toxic by-products, and reduces the need for toxic chemicals such as solvents in the ink, making it medically and environmentally friendly.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
A recent example of a major CAE revamp is MSC Apex, released last month by MSC Software Corp. In a discussion with Design News, MSC executives noted that its next-generation platform is designed to substantially reduce CAE modeling and process time, “in some cases from weeks down to hours.”
The Thames Deckway would run for eight miles close to the river’s edge, rising and falling slightly with the tidal cycle. It will generate its own energy from a series of devices that will line the pathway and use a combination of sources to make the path self-sustaining.
