Prototypes Come to Life in MakerSpace Challenge

Thursday, June 27th, 2024

ABERDEEN PROVING GROUND, Md. — The U.S. Army Combat Capabilities Development Command Chemical Biological Center wrapped up its center-wide MakerSpace Challenge to encourage the use of the lab’s unique capabilities. The four-week long competition pitted the CBC workforce’s potential mission-related prototypes against each other, all while leveraging the various 3D printers offered by the lab.

The competition was touted as a way to promote MakerSpace’s full potential as being the center’s main hub for proof-of-concepts to take shape. All CBC employees were encouraged to participate in creating their own physical or virtual model to be evaluated, as long as it pertained to mission readiness. Competitors were judged by a panel from CBC’s Innovation Council with winners announced in several categories during a Coffee with Colleagues poster session in late May.

CBC acquired its first 3D printer in 1989, just four years after the first commercial grade printer became available to the public. While those antique, hulking machines cost nearly half a million dollars then, MakerSpace now offers 28 machines encompassing 7 different processes, varying from cost-effective tabletop plastic filament models that retail closer to $1,200, to larger units capable of printing with metals.

Bradley Ruphrecht, the MakerSpace lead and an engineering technician at CBC, has been working with additive manufacturing for over 20 years. He says that the MakerSpace challenge offers the chance for all employees to try their hand at experiencing the significant advantages that a physical prototype of one’s own design can offer.

“We had an open house this past November to spread the word on what our lab can offer,” said Ruprecht. “We have a couple of experts here that are always ready to give a quick introduction to our printers to help everyone get started on their first iteration of whatever their trying to achieve.”

Curtis Kreuziger, a general engineer from CBC’s satellite campus located at Rock Island Arsenal, Illinois, was one of several participants and teams selected on the merit of their initial proposals to the competition. Kreuziger had a novel solution to develop a 3D printed, plastic version of the tool that Soldiers use to perform maintenance on their M53A1 protective mask. The valve cassette removal tool — currently a proprietary part that retails for about $2,500 — could possibly now be replicated by utilizing a cost-effective and field-ready solution.

“The challenge announcement gave me an outlet — and an excuse — to go after this prototype I’ve been thinking of for a while now,” said Kreuziger. “This new tool I’m developing can hopefully cut down cost by up to 90 percent for this tool that gets pretty regular use.”

Kreuziger traveled to CBC’s Edgewood, Maryland, headquarters specifically for the MakerSpace challenge due to its multiple printer solutions and material types. He also anticipated his prototype to be created using FDM machines due to their ubiquity in the field. These designs can be utilized from a database, thus making them an ever-ready staple that Soldiers can have access to wherever they have access to a printer.

“The ability to print via multiple techniques and materials cannot be understated,” said Kreuziger. “Some portions of my design, such as the smaller protruding tabs, are just inherently difficult for certain machines due to cooling time or their specific manufacturing process. I would never have known about that until physically holding it. Thankfully I have access to all the different types of printers as the intent is to try them all out.”

Carrington Textiles’ Portuguese Factory Cuts CO2 Emissions by 45% with Biomass Boiler Installation

Wednesday, June 5th, 2024

Adlington, United Kingdom: Global workwear textile manufacturer Carrington Textiles, along with its joint venture in Portugal, MGC, has achieved significant carbon emission reductions following the installation of a biomass boiler at the site in 2023. This initiative has allowed the factory to produce 95% of the steam needed for manufacturing while reducing natural gas consumption by 70%, marking a substantial step towards more sustainable textile production practices.

A biomass boiler is a device that uses organic materials, such as wood chips, agricultural residues, or other biological matter, to produce heat and energy. This technology serves as an alternative to fossil fuels, significantly cutting down on greenhouse gas emissions.

MGC’s biomass boiler uses responsibly sourced wood chips from local forests within a 50 km radius of the factory, all certified by SURE (Sustainable Resources). This raw material consists of leftover wood intended for the paper industry that needs to be removed to prevent fires. The ash generated in the process is used as soil fertiliser after being treated to avoid soil contamination.

This new equipment is carbon neutral and has allowed the textile manufacturer to decrease its overall CO2 emissions by 45% compared to 2022.

Jose Melo, MGC’s Managing Director, commented on the achievement: “The installation of the biomass boiler marks a significant milestone in our journey towards driving energy efficiency in our manufacturing processes. The substantial reduction in our CO2 emissions is a testament to our commitment to environmental stewardship.”

Comprehensive Environmental Initiatives

Beyond the biomass boiler, MGC has implemented a series of initiatives that showcase its commitment to sustainability. This includes reduction in water consumption by over 13%, waste and plastic usage reduction, environmental management training to all employees, energy management systems, wastewater treatment to remove microplastics and PFAs, to name a few.

These initiatives and the implementation of the biomass boiler illustrate Carrington Textiles and MGC’s dedication to investing in technologies that reduce their impact on the environment.

Corps Collaborations: Industry Innovations in Textiles and Medical Tech on Display in North Carolina

Friday, May 31st, 2024

Marine Corps Base Quantico, Va. —

Earlier this month, MCSC’s Program Manager Combat Support Systems, or PM CSS, was on the ground on Tobacco Road for the 2024 FEDTEX Summit– a yearly symposium that connects the DOD’s acquisition community with industry leaders in textiles and tactical equipment—and the 2024 Special Operations Medical Association Conference, a forum that showcases the latest in expeditionary medical technologies.

Hosted at North Carolina State University’s McKimmon Conference Center in Raleigh, FEDTEX provided the team an opportunity to engage with existing industry partners in the textile sector, tour the Wilson College of Textile facilities, and connect with graduate students interested in entering federal service.

According to Col. Paul Gillikin, CSS program manager and NC State alum, “Connecting with the textile community is essential to meet Force Design’s modernization goals and support Expeditionary Advanced Base Operations, or EABO. Strengthening supply chains and integrating advanced textiles and manufacturing techniques are crucial to mitigating the growing risks in the electromagnetic spectrum. It was important to discuss Marine Corps and Joint warfighter needs and then hear industry feedback on that direction.”

Although the Pentagon’s strategic return to the Indo-Pacific has led to a renewed focus on the fielding of expeditionary capabilities meant to dominate the global littorals, experts have warned a future war against our nation’s pacing threat could be decided—in large part—on the electromagnetic spectrum.

Exposing this emerging reality, the Pentagon recently warned that China has developed advanced electromagnetic spectrum monitoring technology, making it difficult for Marines to conceal their presence on the battlefield. From heat signatures to electromagnetic emissions from their gear, the warfighter risks revealing critical information that adversaries can detect and exploit.

With high-end weapon systems dominating the headlines, PM CSS is actively pursuing technology to protect individual Marines and small units. Along with its Joint clothing partners, the team is focused on the visible and non-visible portions of the electromagnetic spectrum to increase capability against emerging sensor threats, particularly in the thermal realm.

Although clothing has historically been seen as a source of comfort and protection from varying weather conditions and ordnance, developments in military technology from our adversaries have forced experts to reimagine the role of textiles on the modern battlefield, viewing them as personal protective equipment– much like body armor– that enhances the warfighter’s lethality and reduces detectability from peer and near-peer adversaries.

According to Ed Howell, Product Manager for Combat Service Support Equipment, “The FEDTEX conference provided an excellent opportunity to explore the state of the art in domestic textiles for Marine Corps tactical uniforms. It was particularly eye-opening to witness the mannequin, PyroMan, undergo a flame test while wearing clothing at the Thermal Protection Laboratory in the Wilson School of Textiles at NC State University. Flame resistance, along with signature management, is one of the key attributes we are seeking in the next generation of Marine Corps Combat Utility Uniforms.”

Similarly, team members from PM CSS’ Expeditionary Medical team were at SOMA to meet with American and international industry partners to explore the latest advancements in field medical technology.

Under Force Design’s strategic blueprint for modernization, collaboration with industry is pivotal for enhancing medical support and operational readiness in contested environments. These efforts aim to improve Marines’ survival while awaiting evacuation, significantly boosting their resilience and effectiveness in challenging situations.

EABO has fundamentally changed field medical operations,” said Navy Cmdr. Kellye Donovan, EMS Team Program Analyst-Pharmacist. “We have shifted from the GWOT’s ‘Golden Hour’ for patient movement to extended patient holding, providing 96-hour patient care in the field. We are looking for industry assistance to push care to a lower level, make medical capabilities more agile and maneuverable, and reduce logistical constraints in a distributed, contested environment.”

Yet, while creating a forum for collaboration with industry is crucial, connecting with students is equally essential to CSS’ mission as engaging the next generation of innovators ensures a continuous flow of fresh ideas and talent, driving the development of critical textile and medical capabilities for the Corps.

Jacqueline Sewell, a Textile Technologist at the Army Combat Capabilities Development Command and matrixed to the Clothing & Equipment Team under CSS, holds both undergraduate and graduate degrees from the Wilson College of Textiles, or WCOT.

“NC State’s programs have provided me with a foundational knowledge of textiles and an avenue to tangibly contribute to increasing our warfighter’s comfort, capabilities, and mission success through their DoD-issued gear,” she said. “Working for the DoD has allowed me to apply the knowledge gained through my education at WCOT to research, develop, test, and evaluate textiles with active-duty Marines stationed across the US (from Mountain Warfare Training Center to Kaneohe Bay) in leading to the acquisition and sustainment of items such as combat uniforms and extreme cold weather base layers.”

Ultimately, the capabilities being developed by CSS in collaboration with the Joint Force and industry partners are helping modernize and strengthening our military forces. Advanced textiles are enhancing protection and reducing detection risks, while emerging medical technologies are improving field treatment and increasing survival rates. These innovations help maintain operational readiness and effectiveness in contested environments, ensuring that our warfighters are equipped with the best possible tools to succeed on the modern battlefield.
