Abstract
Among the many advantages of the recent additive manufacturing technologies, certain limitations still hinder their widespread adoption in industry. Within the family of processes focusing on continuous fibre reinforcement, the inability to embed fibres in narrow regions is the quintessence of these issues. To address this issue and circumvent the need for a redesign-for-manufacturing phase, this work proposes a novel length-scale control algorithm that produces blur print designs. The present work develops two alternative and integrable minimum length-scale processes: a local perimeter controlling method, and a skeleton-based method. Both approaches leverage commonly used filtering strategies, ensuring reduced computational times while effectively deriving the structure’s skeleton.
