“…• Opportunities: o Combined with 3D scanning, AM provides new cost-effective means for producing athlete-specific products 36,39,40,46,53,54 o Parametric CAD files allow for almost limitless iterations of a design to suit specific users and conditions 19,41,42,50,51,56,57 o Part consolidation to reduce assembly costs and open new possibilities with multimaterial AM 51,53,54 o Complex geometries that would not be manufacturable using subtractive methods provide new opportunities to improve performance 42,44,55 • Challenges: o Long-term durability of AM materials for sports applications is unclear, with most studies not containing longitudinal analyses, and featuring limited sample sizes 33,35,42,53 o AM is typically a slower process than traditional manufacturing processes 51,54 o Postprocessing can be time-and labor-intensive 52,54 o Many parts produced with AM must still interface with a conventional part to form a product, limiting geometry 49,51 o Optimization software still requires manual intervention and an understanding of design for AM 52,55 o New products produced through AM may not meet sporting regulations 19,44 o Laboratory testing may not translate to real-world conditions 19,34,56…”
