Design Principles

"Surface quality in additive manufacturing is a critical design parameter that directly influences functional performance and should be addressed through process optimization."

For designers and manufacturers, this insight highlights that focusing on the initial surface finish of AM parts, rather than relying solely on costly post-processing, can yield substantial performance gains. This can lead to more durable, efficient, and cost-effective products, particularly in demanding environments where friction and wear are critical.
