Research Focus Areas

Pioneering AI-Driven Next-Generation Manufacturing

Our research integrates artificial intelligence, advanced additive manufacturing, and autonomous systems to transform how complex products are designed, optimized, and produced in real-world environments. The work runs the full depth of the stack, from resin and nanocomposite chemistry, through the physics of the printing process and in-line quality control, up to the autonomous production systems that put it to work.

Additive Manufacturing Processes & Functional Materials

Advancing vat photopolymerization, digital light processing, material extrusion, and directed energy deposition, from the resin and nanocomposite chemistry up to real-time control of the process as it prints.

Physical AI for Autonomous Manufacturing

Building AI that can run a process, not just describe one. Large language and vision models read machine and sensor data, capture the tacit know-how of experienced operators, and close the control loop on additive manufacturing without a human at every step.

Next-Generation Drone Production

Rethinking how a drone is built. We print a flat 2D sheet that deploys into a functional 3D airframe, so aircraft can be produced at low cost and high rate, and made where they are needed rather than shipped there.

Active Research Projects

State-of-the-Art Research Environment

JDL runs its own fabrication, characterization, and compute rather than queuing for shared facilities. Students design, print, process, and measure in house across KAIST, KPU, and NTU’s Singapore Centre for 3D Printing, and GPU capacity grows with every new grant.

Additive Manufacturing: DLP and FDM printers, in-house filament fabrication, UV curing, two-photon polymerization
Thin-Film & Semiconductor: ALD, PLD, sputtering, e-beam evaporation, PECVD, deep reactive ion etching, yellow room
Characterization: confocal microscopy, SEM, X-ray diffraction, impedance spectroscopy, tensile testing
AI Computing: RTX 5090 nodes, RTX A-series workstations, NAS storage, National AI Computing Center capacity

Virtual Lab Tour

From Lab Bench to Production Line

The drone work now has a company behind it. KEONIX Labs, a KAIST faculty start-up, is taking the lab’s manufacturing research into real production.

Pocheon Center: a civil-military-government site for drone education and production
Printers, training programs, and custom FPV drone builds

Collaborative Innovation Culture

JDL is an Open Lab: research institutes, companies, investors, legal advisors, and global start-ups work alongside the group, so a project can become a venture without ever leaving it.

23 sponsors across government, industry, and overseas agencies
A network spanning KAIST and NTU Singapore, with KRISS, KIMM, and ETRI
A Global Start-up Platform that carries student projects into ventures

Join Our Community

A Lab That Works Together

JDL is small enough that everyone knows what everyone else is building. Postdocs and senior students pick up the newer members, and the group meets, eats, and gets out of the building together.

Help across disciplines: mechanical engineering, computer science, electrical engineering, and materials sit side by side
An open door: ask, and you get time on your problem
Biweekly Friday group meetings, and lab outings through the year

Meet Our Team

World-class researchers pushing the boundaries of science & engineering technologies

Our multidisciplinary team works across vat photopolymerization, digital light processing, material extrusion, and directed energy deposition, from the resin and nanocomposite chemistry up to real-time control of the process as it prints, and on to AI-driven manufacturing automation and next-generation on-site drone production.
