Today's KNOWLEDGE Share

Medella Northwest:

We are thrilled to share a groundbreaking case recently performed in collaboration with Oxford Performance Materials (OPM), utilizing their innovative 3D-printed PEKK (poly-ether-ketone-ketone) technology. This case marks an advancement in orthopedic care, showcasing the remarkable benefits of PEKK implants over traditional metal implants.

Our commitment to cutting-edge solutions led us to partner with OPM to deliver a patient-specific PEKK implant tailored to address a complex orthopedic challenge.


Why PEKK Outshines Metal Implants:

Bone-Like Mechanics: Unlike metal implants, which can be overly rigid and cause stress shielding, PEKK’s mechanical properties closely mimic cortical bone. This promotes natural load distribution, reducing the risk of bone resorption and enhancing long-term implant stability.

Enhanced Osseointegration: PEKK’s unique surface promotes protein adsorption, facilitating superior bone cell attachment and growth. This leads to faster, more complete bone ongrowth compared to metal, accelerating healing and improving outcomes.

Metal-Free Biocompatibility: PEKK eliminates risks associated with metal hypersensitivity offering a safer option for patients with sensitivities. It does not corrode or produce metallic debris, ensuring long-term safety.

Radiolucency for Better Imaging: PEKK’s radiolucency allows for clear post-operative imaging, enabling precise monitoring of bone healing without the interference often seen with metal implants.

Inherent Antibacterial Properties: Studies show PEKK significantly reduces bacterial colonization compared to metal, making it ideal for high-risk cases like joint revisions or trauma, minimizing infection risks.

Modifiable in the OR: Unlike rigid metal implants, PEKK implants can be adjusted during surgery, offering surgeons flexibility to achieve a perfect fit for each patient.

Today's KNOWLEDGE Share What Is Going Wrong in UK Plastics Recycling? Biffa shut its Sunderland plant. Viridor walked away from Avonmouth and Rochester. Yes Recycling Fife collapsed within a year. All three were backed by major investments All three had buyers lined up for recyclate All three are now offline This is not bad luck It is bad structure Over the next four posts I will break down: 1. Why cheap virgin imports are undercutting UK recyclers 2. How weak policy enforcement is fuelling market failure 3. What volatile PRNs and cheap exports are doing to infrastructure 4. Why demand from brands is softer than their promises Let’s start with the first: **Cheap Virgin Resin = Broken Economics** Virgin PE, PP, and PET have been flooding the global market. New capacity in Asia and the US has driven prices down 30 to 40 percent. Meanwhile, recycled plastic costs more to produce in the UK than it can sell for. We are asking UK recyclers to compete with materials made in places with – ...

Today's KNOWLEDGE Share “Robotic 3D printing can compete with traditional boatbuilding”, Simone Barbera and Mattia De Santis, Caracol V2 catamaran was printed in Italy at Caracol’s production center and headquarter in Barlassina, near Milan, with a Heron AM 400, Caracol’s robotic Large Format Additive Manufacturing (LFAM) platform. The lattest was specifically configured with a 7-axis robotic arm mounted on a rail, enabling the printing of parts up to 10 meters in length. How did the collaboration between V2 Group and Caracol come about? Simone Barbera : The collaboration between V2 Group and Caracol originated from a shared vision to revolutionize boat manufacturing through sustainable innovation. V2 Group, a Spanish-company specialized in nautical design and engineering, is seeking to develop electric vessels manufactured sustainably. On the other hand, Caracol, leader in robotic advanced manufacturing technology, had had years of experience working with Large Format Additive Ma...
