InssTek, Inc.

InssTek, Inc. is a Daejeon company that makes directed energy deposition metal additive manufacturing systems. Its machines build metal parts, support new alloy research and coat medical implants. The company is based at Sinseung-ro in Yuseong-gu, Daejeon, and the site says more than 30 of its machines were installed in the past three years.

Systems and products

• Part manufacturing: An all-in-one system for building parts, with 5-axis and 3-axis AM CAM control options.
• Alloy development: A system tuned for new materials, including high-entropy alloys and multi-material builds.
• Implant coating: A system for porous coatings on orthopedic implants, using a dual module that feeds commercially pure titanium powder.
• Custom DED systems: Systems built to customer specifications for aerospace, defense, marine and automotive users.

The all-in-one system is aimed at parts manufacturing, the alloy system at materials research and the implant system at porous coatings for orthopedic implants.

Technology and software

The company's process is called DMT, short for Directed Metal Tooling, which ASTM classes as a directed energy deposition method. Its clogged vibration method powder feeder is described as giving a steady feed rate, a long working life and a wide feed range. Integrated AM CAM software plans toolpaths, process settings and build strategies for multi-axis and multi-material work. The site shows a turbine disk repair example in Inconel 939 and reports AS9100D and ISO 9001:2015 certification. The company also publishes a DED alloy research newsletter, and its site presents alloy work as a quicker path to high-entropy alloys and similar advanced materials.
