On this episode of the Additive Insight podcast, we're joined by Major General Phil Prosser, who has served as a British Army officer and engineer for 33 years. 

In that time, General Prosser has operated primarily across engineering, logistics and supply chain, with tours in Afghanistan, Iraq and Kosovo, and a deployment to support the National Health Service’s Covid-19 effort in 2020. 

Through his current role as Director Joint Support in Defence Support, General Prosser is responsible for, among other things, building out supply chain resilience. This is increasingly bringing him into contact with additive manufacturing technology, with General Prosser joining the Additive Insight podcast to discuss the opportunities for AM in defence. 

Throughout the conversation, we touch on the MOD’s ongoing Project Tampa initiative, the development of digital part inventories, and the use of AM on the front lines.

In the latest instalment of TCT's Innovators on Innovators series, Kat Ermant, Lead Prototype Technician at Peloton, is joined by Brianne Malloy, Senior 3D Printing Engineer at Estee Lauder.

Over the past ten years, Kat and Brianne have forged careers in the additive manufacturing sector, working primarily in design, prototyping and product development at Peloton and Estee Lauder, respectively. Their academic backgrounds, however, are in fine art. 

Today, they come together to discuss their journeys from fine art undergraduates to additive manufacturing engineers, touching on how they get the better of imposter syndrome, the importance of networking for career progression, and their pursuit of additional qualifications while in full-time work. 

They also dig into the definition of an engineer and offer advice to graduates and young professionals.

On this episode of the Additive Insight podcast, we're joined by Lumas Polymers CEO Luke Rodgers.  

Rodgers has worked in the additive manufacturing space for more than 15 years, serving roles related to materials development at Stratasys and later Jabil.  

A few years into his stint at Jabil, the company launched a business dedicated to the development of specialized materials for a range of polymer 3D printing processes. Jabil Engineered Materials would go on to launch products such as the patented polyketone 5000 powder, but this year was the subject of an acquisition by Lumas Polymers. 

Purchasing patents, technical capabilities, expertise and equipment, Lumas Polymers is now set up to continue what Jabil Engineered Materials started, with Rodgers at the helm. 

Throughout our conversation, Rodgers reflects on the achievements of Jabil Engineered Materials, explains why Jabil sold the business to Lumas Polymers, and what we can expect from the company’s product portfolio. 

Rodgers also provides a temperature check on the AM industry and shares his vision for Lumas Polymers.

On this episode of the Additive Insight podcast, we're joined by Croom Medical R&D Manager Dr Shane Keaveney. 

Croom Medical is an orthopaedic device manufacturer that produces more than 250k implants every year. The company was founded in the 1980s and began exploring the suitability of additive manufacturing technology for the production of such devices around 15 years ago. 

Today, Croom Medical would consider itself an expert user of laser powder bed fusion, having deployed the technology to create porous structures that facilitate bone in growth for several years. The company also commenced an R&D project in partnership with Global Advanced Metals on the 3D printing of tantalum in 2020. 

As Keaveney joins the Additive Insight podcast, he shares his thoughts on how materials development is helping the company advance with AM, explains why Croom has focused so much R&D effort on the printing of tantalum, and details how it works with organisations outside of the medical sector.
