You may not have heard of Germany-based Orion AM, and that’s likely because they were formed just before the pandemic. Their goal is to produce parts for advanced applications using aerospace-grade polymers, like PEEK and similar high-temperature engineering materials [the company was recently in the news, as its technology is being used for the first known 3D printed parts to ever touch down on the Moon’s surface]`.
Their unique Thermal Radiation Heating process provides a twist on traditional FFF 3D printing.
Normal FFF processes involve laying down a line of extruded polymer on top of a prior layer. The problem is that the earlier layer has cooled somewhat, making the bonds between the layers less strong. This is quite evident in many typical 3D prints as they tend to break along layer lines. Some even re-orient parts to ensure the layer lines do not align with expected mechanical stresses.
Manufacturing on Demand
None of this would matter if the parts were truly isotropic, where the mechanical properties are identical regardless of the direction of the force. No layer lines would exist.
That’s the typical scenario for injection molding, where the entire part is liquid and crystallizes all at once. As a result, injection molded parts are often seen as “superior” to 3D printed parts, although the geometry constraints can be severe.
Orion AM’s FFF-TRH process apparently solves this issue. While the extrusion part of the FFF process is basically the same, the chamber in which the extrusion takes place is bathed in thermal radiation.
