Xometry Foundation announces partnership with MxD to expand cybersecurity access for Small and Mid-Sized Manufacturers.

Xometry Foundation announces partnership with MxD to expand cybersecurity access for Small and Mid-Sized Manufacturers. XMTR | 5 hours ago The new grant program will lower the cost barrier for small and medium-sized manufacturers working to meet cybersecurity compliance. NORTH BETHESDA, Md., July 27, 2026 (GLOBE NEWSWIRE) - Xometry, Inc. (NASDAQ: XMTR), the global AI-native marketplace connecting buyers and suppliers of custom manufacturing, announced a new partnership with MxD, the nation's Digital Manufacturing and Cybersecurity Institute, to help small and medium-sized manufacturers meet cybersecurity compliance. This partnership is the next phase of the Xometry Foundation, which commits $1 million per year to develop the next generation of engineers and manufacturing talent. Closing the Cybersecurity Gap for Small and Mid-Sized Manufacturers in the U.S. MxD, the federally designated National Center for Cybersecurity in Manufacturing, equips U.S. factories with the digital tools, cybersecurity protections, and workforce training needed to build a more resilient industrial base. It operates a state-of-the-art factory floor in Chicago and runs MxD Learn, a set of programs that prepare students and professionals alike for in-demand, digitally advanced manufacturing careers. This partnership and investment with MxD are a part of Xometry's broader commitment to strengthening the U.S. aerospace and defense industrial base. The grant program is designed to make cybersecurity compliance, including CMMC Level 2, more affordable and accessible for small and medium-sized manufacturers. By lowering the cost of becoming cyber-ready, more businesses can protect their operations, secure valuable government contracts, and create more high-paying job opportunities within their communities. "Like MxD, Xometry understands that cybersecurity cannot be a luxury reserved for large primes," said Berardino Baratta, CEO at MxD. "Small- and medium-sized manufacturers are the backbone of the defense industrial base, yet they're also the most exposed to cyber threats and the least resourced to defend against them. We are grateful for the partnership with Xometry, which will allow us to close that gap - giving smaller manufacturers access to practical, affordable tools to protect their operations and their place in the supply chain." "Too many small and mid-sized manufacturers lack the necessary compliance certifications and credentials they need to compete for defense work," said Silpa Gollapalli, SVP of Commercial and leader of the Partner Network at Xometry. "Through the Xometry Foundation and our partnership with MxD, we're lowering the cost and accessibility barriers, so more manufacturers can meet the highest security standards, win more contracts, and keep growing their business." Earlier this year, the Xometry Foundation launched its first initiatives to build the next generation of innovators through partnerships with the ASME Foundation, the SAE Foundation, the U.S. Space & Rocket Center, and the KID Museum.

Xometry launches the ultimate ai-native platform for manufacturers.

Xometry launches the ultimate ai-native platform for manufacturers. Published: 24 Jul 2026 In July 2026, Xometry launched an AI-powered platform to streamline the entire injection molding lifecycle, offering an expanded materials catalog, instant on-demand DFM feedback, and one-click reordering. These upgrades include real-time pricing and context-aware AI to accelerate procurement and mitigate production errors for manufacturers. How Xometry accelerates procurement and enhances design accuracy. Xometry's injection molding capabilities accelerate procurement workflows and enhance design accuracy for manufacturers across automotive, medical, pharmaceutical, aerospace, defense, and data center industries. The AI-driven marketplace also bridges the gap between traditional processes and modern procurement demands, offering digital tools for high-volume production. The expanded catalog now includes materials like glass-filled Nylon and PLA, and the platform intelligently routes mold-suited parts to injection molding, guiding customers from quote to production. Manufacturers can schedule free Design for Manufacturability (DFM) consultations for early feedback to avoid expensive revisions. Furthermore, a new self-serve reordering feature allows customers to generate quotes easily, preserving production consistency and contract pricing. Vaidy Raghavan, CTO at Xometry, emphasized the need to modernize the procurement experience in manufacturing, stating that their platform is designed to eliminate barriers between great ideas and finished parts. Significance and future perspective. Xometry's wide significance mainly lies in instantaneous procurement and quoting, in which AI significantly analyzes complex part geometries, lowering negotiation times. As the platform improves, it quickly shifts engineering inputs into manufacturing decisions. Meanwhile, end-to-end lifecycle management also integrates low-volume tooling, prototyping, and high-volume production, further allowing engineers to control or track projects. The optimized supplier routing algorithm also directs jobs to the best global partners based on machine capabilities and turnaround times. Looking ahead, the platform's closed-loop system enables predictive manufacturing, increasing cost and lead-time predictions with each order. The integration of AI into systems such as Siemens' Xcelerator facilitates engineers with valuable supply-chain data during the design phase. This not only democratizes complex production by streamlining processes for industries including automotive and aerospace but also allows companies of all sizes to scale without in-house tooling expertise. Impact on the ICT Industry. Xometry's AI-powered injection molding platform positively impacts the ICT industry by shrinking procurement and prototyping times from days to minutes and scaling hardware development from rapid prototyping to high-volume production with strong supply chain resilience. The platform transforms the ICT Industry by integrating instant quoting for speed, AI-driven process guidance for design optimization, and a vetted global manufacturing network for mitigating risks or related challenges. Together, these capabilities drastically accelerate product development cycles and ensure supply chain stability against market volatility, and overall these strategies help teams move faster and reduce bottlenecks. Xometry addresses manufacturing challenges by leveraging an AI-powered engine for instant, automated quoting of complex 3D geometries, mitigating lengthy sourcing delays. Thereby, the platform further reduces high rework costs through on-demand design manufacturability expertise, expanded material options, as well as streamlined and consistent one-click reordering. Impact of the injection molded plastics industry. The global injection molded plastics market size was calculated at USD 358.71 billion in 2025 and is predicted to increase from USD 371.70 billion in 2026 to approximately USD 511.9 billion by 2035, expanding at a CAGR of 3.62% from 2026 to 2035. According to Precedence Research, this transforms the injection molding industry by digitizing traditionally manual, time-consuming procurement and production pipelines by connecting customers directly with a vast and vetted global manufacturing network for everything from prototyping to high-volume scaling. Modern platforms are revolutionizing the injection moulding plastic industry by slashing quoting times to minutes and connecting early CAD designs directly to production through a unified digital thread. This also unlocks global manufacturing access for businesses of all sizes by reducing reliance on single local suppliers and accelerating overall time-to-market. Xometry modernizes injection molding by solving historical supply chain bottlenecks, reducing upfront tooling risks through free DFM consultations, and delivering design-stage feedback that helps customers catch issues early, reduce revision cycles, and avoid costly changes once tooling is in place. The platform streamlines material choices and procurement friction through an AI-driven process recommender and user-friendly one-click reordering, which routes repeat projects directly to the original tooling supplier.
