Fathom CEO Rush LaSelle: Additive Manufacturing Has Reached Production Maturity After 15-Year Qualification Grind

Fathom CEO Rush LaSelle told 3DPrint.com that the additive manufacturing industry has finally reached the level of maturation needed to deliver repeatable industrial outcomes, a milestone he says was 15 years in the making. Speaking from the AIAA SciTech Forum in Orlando, LaSelle described how Fathom has evolved from a traditional service bureau into a manufacturing partner focused on engineering support, post-processing, heat-treatment coordination, machining, inspection, and qualification workflows for aerospace, medical, and defense customers. The company is seeing particularly strong demand in metal additive (DMLS), where LaSelle noted that supply cannot keep pace with rapidly growing demand, and in defense-related drone applications accelerated by lessons from the war in Ukraine.

This shift reflects a broader industry transition that the AMPulse framework identifies as the core maturation arc: the move from machine-centric marketing to production-centric operations. Fathom's experience mirrors the aerospace qualification grind that GE's LEAP fuel nozzle exemplified - a multi-year journey where success becomes infrastructure rather than headline. The company's pivot from "service bureau" to manufacturing partner aligns with the industry's recognition that printing is only one piece of the value chain; post-processing, quality documentation, and process repeatability are where real value is captured. LaSelle's observation that "very few parts get printed and shipped" underscores the materials qualification discipline and post-processing discipline that separates production-ready operations from demo cells.

For the industry, Fathom's trajectory confirms that the traditional service bureau model is giving way to a more integrated manufacturing services approach. The company's focus on metal DMLS and defense applications positions it to capture demand from startups that need production rigor without building their own qualification infrastructure. The practical takeaway: Fathom must continue investing in quality systems and engineering talent to maintain its differentiation as more competitors attempt the same transition. For buyers, the message is clear - look for partners that can manage the full manufacturing workflow, not just the print cycle.
