Technology & Products
Key Products
Printed ultra-high temperature NDE sensors; Aerosol jet printed electronics; In-line inspection tools (EMAT, UT); Robotic NDT sensors
Technological Advantage
Qi2 leverages proprietary aerosol jet printing and material science to fabricate ultra-high temperature NDE sensors directly onto complex structures, a capability validated through NASA and DoD projects. Their long history of innovation and patent portfolio in sensing and inspection provides a defensible technology moat, though the core printing process is replicable by well-funded competitors like Optomec.
Differentiation
Value Proposition
Enables conformal, on-demand placement of ultra-high temperature NDE sensors directly onto complex structures, reducing lead time and cost versus discrete sensors while improving reliability in extreme environments (e.g., >1000°C).
How They Differentiate
Unlike Optomec, which sells aerosol jet printers, Qi2 focuses on end-use sensor applications, leveraging 50 years of NDT expertise to deliver conformal sensors that survive ultra-high temperatures, validated in NASA and DoD programs.
Market & Competition
Target Customers
Government agencies (NASA, DoD), aerospace OEMs, and energy/pipeline operators requiring advanced non-destructive testing and harsh-environment sensing.
Industry Verticals
Aerospace; Defense; Energy; Industrial
Competitors
Optomec; Neotech AMT; Nano Dimension
Growth & Milestones
Growth Metrics
Growth signals identified: Quest Integrated, LLC merged with Quanta Inline Devices, LLC in 2021 to form 'Qi2 Elements' (storage tank/pipeline inspection). Qi2 Elements was subsequently acquired by Baker Hughes on 2022-03-07 and is no longer part of Quest Integrated/Qi2's portfolio; Qi2 corporate retains the aerospace/defense NDE sensor business under Milton Altenberg. Per public sources (rocketreach/SBIR aggregation), ~108 employees and ~$3.8M annual revenue as of July 2025.
Major Milestones
1970: Founded as FLOW Research; 1990: Renamed Quest Integrated, LLC; 2019: Received investment from European energy private equity; 2021: Merged with Quanta Inline Devices to form Qi2 Elements
Notable Customers
