Integrating 3D (three-dimensional) printing technology has significantly enhanced haptic design, application development, and system performance. This study explores various 3D-printable materials for haptic devices, emphasizing their mechanical qualities, flexibility, and practical use. Rigid polymers like PLA (Polylactic acid) and ABS (Acrylonitrile Butadiene Styrene) ensure structural integrity, while flexible materials like TPU (Thermoplastic Polyurethane) and silicone-based resins mimic human skin's tactile perception. 3D printing improves the precision of mechanical actuators, sensors, and responsive materials used in haptic feedback, allowing rapid prototyping and unique shapes. The advancements in haptic devices, driven by 3D printing, enable the creation of personalized components that meet specific user needs. In healthcare, these devices are used for surgical training, organ and limb replacement, and physiotherapy. In virtual and augmented reality, haptic feedback enhances user interaction. The aerospace and defense industries utilize haptic devices for simulation, remote operations, and communication, while consumer electronics benefit from increased engagement and improved product quality.

The pharmaceutical industry is a representative case, with manufacturers catering for emerging gene therapy and vaccine applications reporting delays and shortages in recent years due to the unforeseen pandemic, the need to rapidly re-purpose manufacturing resources, combined with uncertain process performance of established capacity. Whilst process uncertainty is often quantifiable, tackling unforeseen demands requires the establishment of flexible production platforms. To this end, we present a framework for the quantification of network design flexibility integrating quantified process uncertainty. Network reliability metrics are quantified through scenario-based chance constraint programming and solution quality is tested via Monte Carlo simulation. Cost-reliability plots are obtained to pinpoint the required costs and capacity to meet a target probability of product demand satisfaction. Given an upper bound in cost and fixed design, the tool is also used to map out a feasible solutions space, quantifying maximum network reliability.

This gap is largely defined by the prohibitive capital cost, extended timelines, and significant risk associated with traditional pilot plants. To bridge this gap, this paper introduces the <i>Minimum Viable Pilot Plant (MVPP)</i> framework: a lean, hypothesis-driven approach to de-risking process technologies through targeted, capital-efficient experimentation. Grounded in both historical engineering practice and lean startup principles, the MVPP formalizes a reproducible method for maximizing the learning-to-capital ratio and generating high-fidelity data to validate the most critical techno-economic assumptions. Instead of replicating a full-scale plant, the MVPP isolates and tests the single riskiest process element using minimal hardware. Its iterative application enables progressive de-risking of complex, system-level challenges. Illustrative case studies are presented to demonstrate how the MVPP model accelerates technology validation, reduces investment barriers, and democratizes innovation in the chemical industry. While the MVPP is a promising tool, it is not a panacea. Nevertheless, it can accelerate commercial chemical process innovation, particularly in resource-constrained environments, and it opens opportunities for further studies.</p>","PeriodicalId":87290,"journal":{"name":"Journal of advanced manufacturing and processing","volume":"7 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://aiche.onlinelibrary.wiley.com/doi/epdf/10.1002/amp2.70046","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145877097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fiber steering requires large nozzle rotations to keep the fibers tangential to the nozzle path. If the print speed is not reduced accordingly, the resulting large robot joint accelerations cause jerky movements and vibrations that disrupt the precise printing height—typically ranging from 0.1 to 0.3 mm—causing fiber damage at the nozzle tip and path errors. This research introduces a novel approach called Maneuverability-based Speed and Temperature Adaptive Robotic Control (M-STARC). The method dynamically adjusts printing speed and deposition temperature based on the complexity of the robotic joints' maneuvering required to maintain tangential alignment of the 3D printing nozzle with the fiber path trajectory. Heat transfer analyses determine nozzle temperature as a function of printing speed. This speed is varied along the trajectory to limit robot joint accelerations, which depend on the maneuverability (kinematics) of the robot. Faster printing speeds (and higher nozzle temperatures) are allowed at points where less maneuvering is needed. The proposed toolpath planning approach effectively defines the 3D path and robotic movements while adhering to critical speed–temperature constraints, laying the theoretical foundation for future experimental validation and implementation in fiber steering applications.</p>","PeriodicalId":87290,"journal":{"name":"Journal of advanced manufacturing and processing","volume":"7 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://aiche.onlinelibrary.wiley.com/doi/epdf/10.1002/amp2.70044","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145366720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
