Xometry unveils AI model upgrades to improve manufacturing recommendations and pricing.

Xometry unveils AI model upgrades to improve manufacturing recommendations and pricing. July 20, 2026 Manufacturers increasingly rely on AI-powered software to accelerate quoting, identify the right production methods and connect with qualified suppliers. As custom manufacturing workflows become more complex, improving the accuracy of those decisions can reduce costs, shorten lead times and simplify procurement for both buyers and manufacturers. Xometry Inc. (NASDAQ: XMTR) has introduced a broad upgrade to the artificial intelligence models that power its digital manufacturing marketplace, rolling out a new architecture designed to improve process recommendations, pricing accuracy and supplier matching. The North Bethesda, Md.-based company said the enhancements are built on proprietary data spanning part geometry, manufacturability, pricing, supplier capabilities and production outcomes, creating a more connected intelligence layer across the manufacturing process. One of the most significant changes is an updated context-aware recommendation engine that helps customers determine the most appropriate manufacturing process as soon as a part is uploaded. Rather than relying primarily on a customer's order history, the model evaluates factors including a part's geometry, likely material selection and intended industry application. For example, the system can recognize when aerospace components may require tighter tolerances or specialized alloys before generating recommendations across Xometry's 20 supported manufacturing processes. The company said the approach addresses the "cold-start" challenge commonly encountered with first-time users and has resulted in buyers accepting the automated manufacturing recommendation more than 85% of the time during early deployment, with the strongest gains among new customers. Xometry has also introduced a new generation of cost-prediction models beginning with CNC machining. The upgraded models evaluate a broader range of manufacturing variables, including geometry, materials, surface finishes and whether a part is produced individually or as part of a larger manufacturing job. According to the company, live testing showed the models improved CNC cost-prediction accuracy by approximately 15%. The pricing models also generate calibrated confidence levels for each CNC quote, allowing the platform to assess pricing certainty before returning an estimate. Xometry plans to expand the upgraded models to additional manufacturing processes supported by its Instant Quoting Engine(R) while adding more CNC materials over time as additional historical production data becomes available. Supplier partners are also expected to benefit from new adaptive sourcing models that refine how manufacturing work is distributed across the marketplace. The updated system evaluates machine dimensions, specialized manufacturing capabilities, historical quality performance and on-time delivery records when matching jobs with suppliers. Instead of receiving broad notifications for available work, participating manufacturers are presented with a more targeted stream of opportunities aligned with their capabilities. Xometry said the improvements have significantly strengthened partner matching while accelerating sourcing decisions for buyers. "Across the millions of parts quoted through Xometry, our AI is constantly learning," said Vaidy Raghavan, the company's chief technology officer. "Our new models move beyond treating that knowledge as separate skills, where one model recommends how to build something, another prices it, another finds who should build it. Now, they are an intelligence layer that gets sharper every time a part moves through it." Raghavan added that the company's data models increasingly determine how parts are manufactured, what they cost and which suppliers are best suited to produce them, enabling customers to receive more accurate recommendations, pricing and supplier matches with each new project submitted through the platform. Xometry operates an AI-powered marketplace connecting buyers with manufacturing suppliers worldwide while also operating the Thomasnet(R) industrial sourcing platform and a suite of cloud-based manufacturing services. The company says its technology is designed to streamline procurement by providing real-time pricing and lead-time information while helping manufacturers secure production opportunities more efficiently.
