In the procurement process, material selection is among the most important considerations. As most will know, choosing a material with the right mechanical, thermal, and chemical properties can mean the difference between a successful application and part failure. In today’s world of rising supply chain volatility and material scarcity, however, you can’t always rely on your first choice material being available. Let alone in a way that conforms with lead times and budgets. Material substitution is therefore an increasingly critical part of a resilient supply chain strategy. One that enables manufacturers to overcome bottlenecks caused by material shortages and adapt to a changing raw material landscape while maintaining production consistency. Smart material substitution, in particular, is supporting suppliers as they transition from reactive procurement to more sustainable, agile production. In this article, we’ll look at how material scarcity and material shortages can cause significant supply chain challenges and how smart material substitution is a strategic solution. By turning to intelligent online manufacturing services like FACTUREE, procurement specialists and manufacturers can now exploit the benefits of smart material substitution and rely on consistent, high-quality production. <h2>When materials become a bottleneck</h2>Every manufacturer’s goal is to establish a reliable, resilient supply chain. However, with this goal dependent on many factors (such as access to labor and machines, efficient logistics, and degree of material scarcity) a completely invulnerable supply chain is practically impossible to achieve. Materials alone can create a variety of bottlenecks in production chains, ranging from short-term delays to more significant long-term issues that can disrupt manufacturing and destabilize supply chains. Short-term production bottlenecks can be caused by simple delays in material shipments due to weather, geopolitical dynamics, and infrastructure issues. For example, in 2021, when an Evergreen containership blocked the Suez Canal for six days, an estimated $9.6 billion worth of goods was delayed each day. [1] Another reason for short-term bottlenecks is materials not meeting quality standards when they are delivered, making them unsuitable for use.  More impactful long-term bottlenecks caused by material shortages can be traced to several root issues. These include reliance on single-source or scarce materials, regionally constrained raw materials, long qualification cycles, and demand outpacing supply. Such is the case with molybdenum, a refractory metallic element commonly alloyed with steel for energy and automotive applications. With demand growing for the element, production has failed to keep up — one reason being the difficulty in obtaining new mining permits in China. As a consequence, prices for the material have surged, rising 34% between 2022 and 2023 in the U.S. market. [2] Recent geopolitical instability, notably between China and the United States, has also led to significant global supply chain disruptions in the form of export restrictions, sanctions, and tariffs.It goes without saying that challenges in securing a steady material supply have wide-reaching impacts on the production chain, including: <ul><li>Production continuity</li><li>Quality and compliance</li><li>Cost and lead time commitments </li></ul>Overall, material-driven production bottlenecks can cause severe supply chain disruptions, making manual or reactive procurement strategies ineffective. Smart material substitution is therefore becoming a strategic necessity that can not only help overcome material shortages but can anticipate them and fill material sourcing gaps before they impact production schedules. <h2>What is material substitution?</h2>Before going any further, let’s break down what constitutes material substitution. In simple terms, material substitution is a resilient supply chain strategy that enables the transition from a scarce material — or a bottleneck-prone material — to a functionally equivalent alternative. For example, there are broad-scale efforts to transition away from using rare materials to more Earth-abundant materials. We see this in the photovoltaics sector, where research is advancing towards substituting aluminum and copper for silver, a more critically raw material. [3] The primary considerations in material substitution relate to functional material properties. In other words, the substituting material should meet the mechanical, thermal, electrical, and chemical requirements of the application in question. If you are manufacturing a part for the maritime sector that requires a combination of strength, durability, and extreme corrosion resistance, the substitute material should deliver on all fronts or could fail under the specific stresses of the maritime environment. Other important considerations when selecting a substitute material are related to the following:<ul><li>Manufacturability and process compatibility (i.e. can the replacement material be processed using the same production technique and parameters as the first-choice material) </li><li>Regulatory and certification constraints (i.e. is the material validated for the sector/application area in question)</li><li>Availability on the global market </li></ul>In the best cases, the substituting material will not only meet all functional and regulatory requirements, it will also be easier to source, more sustainable, and more cost-efficient than the first-choice material.<h2>Why use smart material substitution</h2>When we talk about smart material substitution, we are not simply referring to substituting like-for-like materials. Rather, smart material substitution is a strategic approach that uses algorithm-driven software to identify optimal material options. This intelligent approach can be built into procurement and manufacturing workflows and takes the legwork and guesswork out of material substitution by generating rapid solutions based on reliable data. This data is derived from various sources, such as certification documentation, material property databases, historical performance reports, life cycle assessments, and cost, availability, and lead-time signals.This algorithm-based approach to material substitution is more powerful, responsive, and scalable than manual processes, which are highly dependent on individual expertise and tend to be more reactive in nature. This expanded capability is owed to software’s ability to simultaneously evaluate a multitude of variables, from mechanical properties and manufacturing processes to cost and global availability. This multidimensional optimization enables manufacturers to make the best choice based on not one but all factors. Moreover, smart material substitution can use different types of algorithms, including rule-based filtering, optimization models, and machine-learning similarity and performance prediction. By integrating this multifaceted model into production workflows, suitable material substitutes can be rapidly screened. Moreover, top alternatives can be backed up by insights that illuminate the similarities and trade-offs between different material options. <h2>The benefits of smart material substitution</h2>For manufacturers and procurement teams alike there are many things to gain from integrating a smart material substitution strategy. In addition to the central benefit of being able to rapidly assess a wider variety of materials based on an enormous amount of data in a truly scalable way, we see other advantages related to productivity, sustainability, and overall supply chain resilience. These benefits include: <ul><li>Reduced production stoppages and downtime caused by specific material shortages.</li><li>Improved cost control in volatile conditions (and in some cases lower material costs). </li><li>More standardized material selection processes within an organization, even across different projects and teams.</li><li>Increased sustainability through the use of LCAs in the algorithmic model, which can factor in a material’s carbon footprint.</li><li>More proactive risk analysis that uses real-time data (such as availability, cost, geopolitical signals) to anticipate material bottlenecks and pre-plan substitutions.</li><li>Increased agility and future-proofing, resulting in shored up supply chains that are ready for expected and unexpected hurdles. </li></ul><h2>Material substitution made easy with FACTUREE</h2>Online manufacturing services and networks are facilitating access to smart material substitution. Manufacturers like FACTUREE, which operates an AI-driven platform that matches procurement inquiries for custom parts with qualified manufacturers in its 2,000-strong network. FACTUREE’s intelligent solution effectively matches client requests with manufacturers based on criteria like design requirements, tolerances, production method, and material availability.If a primary material for a custom part is unavailable or is impacted by an unstable supply, the company is able to provide the client suitable alternatives based on material properties, manufacturability, cost and inventory. Thanks to the AI that analyzes and qualifies requests with the help of real time people who have a final look at every single inquiry coming in.The AI that FACTUREE uses was trained since 2017 with real-world data on material properties, manufacturability, price and inventory of the supplier network. The continuously growing dataset, which now includes over 600,000 data points, currently represents almost the entire manufacturing market, eliminating the need to inquire about individual supplier manufacturability. So, for example, if a customer wants to order parts made from aluminum but the price of aluminum is unstable FACTUREE is able to suggest — on customer request — a functionally equivalent metal or even polymer to ensure production continuity is maintained. Moreover, FACTUREE can advise customers on beneficial material substitutions even when material shortages are not an issue. For instance, high-performance thermoplastics such as PEEK are increasingly being adopted as a cheaper, more lightweight alternative to metal in industrial applications that require low weight, electrical insulation, and chemical resistance. Smart guidance on material substitutions can therefore not only alleviate supply chain challenges, but can enhance part performance and help improve bottom lines. Not only is the FACTUREE supplier matching system accessing the trained AI, but also the new domain-based AI agent FACTUREE Navigator that was launched in late 2025. Anyone who procures or designs components is often faced with the same questions: Which material is best suited? Which surface treatment suits the process? Such decisions require specialist knowledge and cost time. The <a href="https://www.facturee.de/en/facturee-navigator/ki-agent-explains/" target="_blank">FACTUREE Navigator, a free-to-use tool without a login</a>, closes this knowledge gap. The new AI-supported agent answers technical questions about materials, manufacturing processes and surface treatments in a matter of seconds. It makes complex manufacturing knowledge available to everyone for the first time. With responses informed by a wide range of proprietary data, Navigator can help FACTUREE customers find material substitutes while also benefiting from lead time improvements and lower costs, all without sacrificing quality or performance.<h2>Conclusion</h2>Ultimately, as manufacturers and procurement professionals seek to establish more resilient supply chains, smart material substitution has a central role to play. Intelligent algorithms, as demonstrated by the platform capabilities of FACTUREE, can harness vast quantities of material data and enable manufacturers to choose suitable material alternatives when primary raw materials are scarce. This approach can establish greater stability in an increasingly volatile raw materials market and ensure that parts meet all requirements in terms of production scales, schedules, and budgets, as well as performance and quality.<h2>References</h2>[1] Harper, Justin.

Reinforcing the Supply Chain with Smart Material Substitution

Kickboxing rehab is becoming measurable as Saxion University of Applied Sciences combines Xsens motion capture with pressure sensor data to quantify recovery and support better return-to-training decisions.Challenge:Kickboxing rehab is difficult to track with traditional, manual methods, and common tools do not capture punch and kick performance in a sport-specific way.Solution:Using the Xsens Link suit and pressure sensors on pads, Saxion records full-body movement and strike output during structured sessions to generate objective recovery metrics like left-right symmetry.Key takeaways:<ul><li>Built for real training environments: Inertial motion capture requires no studio, making consistent weekly measurements practical.</li><li>Movement plus output: Xsens provides full-body context while pressure sensors quantify strike impact, connecting technique to results.</li><li>Clear progress signals: Metrics like symmetry and repeatable best-effort punch analysis help physiotherapists track improvement over time and guide return-to-sport decisions.</li></ul>Kickboxing is an unsurprisingly dangerous sport. While exciting to watch, throwing uppercuts, jabs, and roundhouse kicks can easily lead to injuries for athletes. To better understand and improve rehabilitation in this demanding field, researchers at <a href="https://www.saxion.nl/" target="_blank" rel="noopener noreferrer">Saxion University of Applied Sciences</a> are exploring new methods of monitoring recovery.<img src="https://s3-us-west-1.amazonaws.com/wevolver-project-images/froala%2F1770814514683-Saxion+UFC+Figther+2.jpg" style="width:100%px" class="fr-fic fr-dib" />Closing the gap in kickboxing rehab research“There isn’t much research around kickboxing rehab, especially concerning the use of technology for monitoring rehabilitation,” says Katrien Fischer, researcher and human movement scientist. “Traditional analysis methods are quite manual, making them difficult to quantify and analyze, as these challenges aren’t sport-specific.”Athletes are typically assessed with ground reaction force plates, which are highly effective in sports like running, football, or long jump. However, these tools fall short when applied to combat sports, where punches and kicks are crucial. This gap highlights the need for more specialized approaches tailored to the unique demands of kickboxing.“It’s also important to consider the culture of rehab in boxing and kickboxing,” adds researcher and physiotherapist Remco Kuipers. “Often, not much is done. Fighters tend to push through pain and focus on getting ready for their next match.” This combination of minimal rehabilitation and limited technology has historically made it difficult to measure recovery in combat sports – something the Saxion team aims to change.Full-body kinematics for punches and kicks with inertial motion captureTo tackle this challenge, the researchers turned to Xsens motion capture technology. “We knew Xsens was the right choice because we’ve worked with the system in the past,” explains Katrien. “We opted for the Link suit because of its low latency and ability to pick up on every nuance. Now, we’re using it every week.”The Xsens Link suit is a full-body system with inbuilt sensors that track joint rotation, angles, and velocity. Unlike camera-based setups, it requires no dedicated studio space, making it easy to use anywhere. For athletes with busy training schedules, this convenience makes rehab sessions more accessible and less time-consuming.Inertial motion capture also allows rehabilitation to take place in flexible locations, without the need for specialized labs. Researchers and physiotherapists can bring the technology directly to the athlete, enabling efficient and high-quality analysis on the spot.“We’ve developed a detailed, structured motion capture process to keep data collection consistent,” says Remco. “It involves a warm-up of shadowboxing and pads with a professional trainer. Then we measured eight sessions of kickboxing with a one-minute break between each one. We asked the subject to hit with maximum voluntary contraction, then take the five strongest jabs, crosses, hooks, and uppercuts for analysis.”From subjective feedback to objective rehab decision-makingBy combining motion capture data with pressure sensor measurements, researchers can generate quantifiable insights into performance. One approach they are exploring is the limb symmetry index (LSI), which compares the performance of one arm or punch against the other. Using pressure sensors embedded on pads, this method provides a precise way to measure strength and coordination in combat-specific movements.This kind of objective data has the potential to transform rehabilitation in combat sports. Instead of relying primarily on subjective feelings, physiotherapists could base recovery programs on measurable progress, leading to better outcomes for athletes.“Using Xsens for this project will bring new findings to both us at Saxion and the physiotherapy sector as a whole,” concludes Remco. “We look forward to gathering data that shows improvements in speed, force output, grip strength, and endurance – all essential elements in combat sports performance.”

TenCate Grass is pushing the boundaries of what an artificial pitch can be, using Xsens motion capture to turn every step, cut, and sprint into actionable insight. By grounding their turf innovation in real athlete data, TenCate is creating sustainable next-generation surfaces that feel like natural grass.Challenge:TenCate needs to create a new, sustainable way to manufacture artificial turf – and it needs to perform just as well as the real thing.Solution:Using Xsens, the TenCate research team can test athletes on different surfaces, validating the new turf material.Key takeaways:<ul><li>From lab to pitch: Tencate tested artificial turf in various locations and conditions.</li><li>Combining camera and mocap: Recording athletes with cameras allows for analysis of one part of the body. Xsens supports this with the full context, demonstrating how each surface affects performance.</li><li>Visual indicator of performance: Showing motion capture data from two surfaces, side by side, helps researchers determine which material to prioritize.</li></ul><a href="https://www.tencategrass.com/" target="_blank" rel="noopener noreferrer">TenCate Grass </a>is the world’s leading producer of artificial turf, supplying surfaces for professional sport, community clubs, and municipalities worldwide. Beyond manufacturing, the company invests heavily in R&amp;D at its Center for Turf Innovation in the Netherlands, where its mission is to create turf that feels and performs as close to natural grass as possible.With over 3000 square meters indoor lab – plus access to full-size natural grass and artificial pitches – TenCate works closely with professional athletes and clubs such as PSV Eindhoven to define what makes the perfect grass for each sport, team, and environment. But simply observing players wasn’t enough. To truly understand how surfaces influence performance, TenCate turned to Movella’s Xsens motion capture technology.“We wanted a system that could tell us exactly how athletes move on different surfaces,” says Tom Wills, Manager of the Center for Turf Innovation at TenCate Grass. “Xsens gives us biomechanical data we can’t capture with cameras alone – things like stride length, joint angles, and acceleration patterns.”Sustainable alternativesTraditionally, artificial turf relies on recycled rubber tyre crumb as infill. However, with the EU’s upcoming 2031 ban on microplastics, that material is being phased out. Which, for TenCate, is something of an opportunity.The R&amp;D team is now testing alternatives – including wood chips, cork, and olive stones – as well as developing non-infill turf systems. And to validate these new designs, biomechanics is essential. By capturing data directly from athletes on the pitch, TenCate can compare movements on new prototypes versus natural grass.“People adapt their movement patterns depending on the surface,” explains Tom. “With Xsens, we’ve seen that our non-infill systems are beginning to replicate natural grass performance, which is exactly where we want to be.”Testing in real environmentsUnlike camera-based systems that are limited to the lab or small test zones, Xsens’ portable IMU-based system allows TenCate to run studies on real fields, under real playing conditions.At their innovation center and at partner sites such as PSV Eindhoven’s training ground, TenCate researchers observe athletes performing drills, from sprint starts to sharp 180° turns. The Xsens system records movement seamlessly across multiple pitches, with only quick recalibration needed between surfaces. Sessions typically last up to two hours, limited not by the equipment but by player fatigue. Data is then cross-referenced with high-speed video for detailed surface interaction insights.“The combination of cameras and Xsens gives us the full picture,” says Tom. “We can zoom in on foot-to-surface contact with cameras, and then use Xsens to understand whole-body motion leading to that movement. It’s a level of insight we simply couldn’t get otherwise.”Beyond the raw data, Xsens also provides powerful visualization tools. Coaches, physiotherapists, and decision-makers can view 3D avatars that compare movement patterns across different surfaces – making complex biomechanics easy to understand.“Not everyone can interpret a graph of hip flexion angles,” Tom laughs. “But when you show them two avatars side by side – one running on natural grass, one on an alternative turf – it clicks. People understand. That visual impact is hugely valuable.”Long-term innovationTenCate has been using Xsens since 2021, and the technology has become central to its product development cycle. From early-stage lab tests to large-scale field trials, motion capture data ensures every innovation is backed by hard evidence.For athletes, the system is comfortable and, crucially, not an obstruction once play begins. For researchers, it delivers reliable, repeatable data. And for the wider sports industry, it means safer, higher-performing, and more sustainable pitches.“Xsens has given us the ability to move beyond opinion and perception, and into measurable, repeatable performance data,” concludes Tom. “That’s critical as we redefine what artificial turf can be.”
