Visualizing the Invisible
We don’t stop at showing what’s invisible — we build systems that decide for themselves. We read the composition of material on the conveyor, in real time, without stopping the line.
Why it matters
Raw material that could never be fully inspected —
now read in full, without stopping
In 2022, Hyundai Steel bought about KRW 6 trillion of steel scrap. The volume made it practically impossible to check every load for impurities. That problem is where 3I began.

Technology
Three eyes
on one material
Neutrons see composition, X-rays see shape, optics see the surface. The three meet at one point and become data — and AI makes the process decision.
More on technologyNeutron · PGNAA
We read what a material is made of from the energy of the gamma rays each element emits when it captures a neutron.
X-ray
Transmission imaging reveals inner shape and foreign objects. Combined with composition, it shows what is where.
Optical laser
A laser line sweeps the surface to find wear, cracks and damage.
AI analytics platform
Real-time analysis, remote monitoring and predictive maintenance automate process decisions.
Prompt Gamma Neutron Activation
The moment a neutron meets an element,
the element says its name in light
Iron at 7.631 MeV, calcium at 6.420 MeV. Read each element’s signature gamma energy and you know the composition — without taking a sample.
Products
From compact analyzers
to conveyors, cargo and robots
Every system is built to be installed on the plant floor, not in a lab. Orange marks the point where the material is read.
All productsApplications
Know the composition,
control the process
Without knowing the raw-material mix, process efficiency drops and carbon is hard to manage. Real-time, full-stream data removes that uncertainty.
Steel & Cement
Raw material for sintering, EAF scrap and cement kilns — in real time.
Battery Recycling
Stabilize Li · Ni · Co · Mn in black powder for better yield and cost.
Material Analysis
Precise composition of advanced materials with X-ray and neutrons together.
Damage Detection
Wear and cracks on equipment and robots, found instantly by laser scan.
Company
Born inside
Hyundai Motor Group
We started in a Hyundai Steel task force on scrap grading, grew as a group in-house startup, and became independent in 2023.

Innovation of Invisible Inspection
3I means three eyes
An extended sense that sees beyond human sight — turning the Invisible into Insight, and Insight into Intelligence that decides for itself.
