A NIMS research team fabricated heat-resistant steel test specimens using laser powder bed fusion (LPBF)—a form of metal 3D printing—and subjected them to creep testing for up to 10,000 hours.

Heat crawling up the hot end like this is known as heat creep and there are a variety ... heat-break and a fan can do the job for common 3D printing tasks, there can be problems.

Next, Schone worked through several extruder iterations, focusing on reliable output for 3D printing. ‘Heat creep’ was another big hurdle that the maker successfully conquered. Continuous glue ...

D printing technique from Chalmers University of Technology reduces cracking in turbine blades exposed to extreme heat and ...
