Opportunities and Challenges of 3D Scanning Technology in Quality Control and TPM Strategies for SMEs within Industry 4.0

The adoption of 3D scanning technology in quality control is increasingly vital for small and medium-sized enterprises (SMEs) pursuing Industry 4.0 and smart manufacturing initiatives. This study investigates the benefits and challenges of integrating 3D scanners into SME production processes, with a particular focus on their role within Total Productive Maintenance (TPM) strategies. Using data collected from a structured survey of SMEs operating in manufacturing sectors, the research analyzes key factors influencing technology adoption, including financial constraints, technical expertise, infrastructure readiness, and cybersecurity concerns. The results reveal significant relationships between these factors, highlighting areas where SMEs struggle to balance long-term benefits with operational realities. Additionally, the study demonstrates how 3D scanning, when combined with TPM practices, can improve product quality, accelerate inspection workflows, reduce equipment downtime, and enable more effective, data-driven maintenance planning. Based on these insights, practical recommendations are provided to assist SMEs in overcoming implementation barriers and leveraging 3D scanning as a strategic enabler for enhanced manufacturing competitiveness, operational efficiency, and maintenance management.
