SGLB TED and NIST TEMPS. Speculation welcome.
From sglb last pr.

Sigma Lab's PrintRite3D® INSPECT™ V3.0 software is a web-based, distributed application featuring 3D Thermal Mapping of the melt pool using Sigma Labs’ proprietary TED™ (Thermal Emission Density™) metrics. These metrics are an industry first and powered by an advanced analytics engine, designed to meet the needs of users focused on research, development and qualification-level activities as well as day-to-day production activities.

Manufacturers of powder bed fusion machines generally do not allow modifications by end-users and are reluctant to provide open access to software and control systems. This creates barriers for the development and implementation of real-time process control. Therefore, this project will develop an open AM platform and supporting facility called the Additive Manufacturing Metrology Testbed (AMMT) to test and demonstrate the in-process measurement and control methods. This system development is co-led by the efforts by NIST Physical Measurement Laboratory (PML) to develop a traceable surface temperature and emittance measurement system called Temperature and Emissivity of Melts, Powders, and Solids (TEMPS). Such a system will enable us to directly observe melting and solidification of metal powders, integrate in-situ process metrology tools, implement software interfaces and data acquisition for process measurements as well as test the open and closed-loop control algorithms.
