Electron Beam Quality
一Ensuring Build to Build Consistency for serial production in metal additive manufacturing
Using the electron beam control technology from the world's highest performance electron microscope and electron beam lithography system for semiconductor manufacturing, JEOL has developed an advanced electron beam powder bed fusion 3D printer that can produce high-density and strength parts with a high-power and fast electron beam. JEOL’s Electron Beam Metal 3D Printer produces parts that meet regulated industry standards and requirements, allowing for manufacturers to scale their production demands.
Features
01. Hot process
Preheating using electron beam to eliminate distortion and cracking
Electron beam additive manufacturing reduces the sudden temperature change of a build due to preheating using an electron beam (hot process). Therefore, the parts will have little residual stress, resulting in reducing distortion and cracks. On the other hand, laser additive manufacturing tends to accumulate residual stress by repeated heating and rapid cooling, resulting in deformation and cracks of the build depending on the material and shape.
Laser additive manufacturing requires strong supporting material to avoid such deformation and cracks. Electron beam additive manufacturing can reduce the supporting material since the surrounding powders are lightly bonded to each other to support the build, which is an advantage.
Moreover, while the laser method needs to alleviate the stress inside the build through a heating processing after manufacturing, the electron beam method does not require such post-processing.

curved section without supports
02. High vacuum environment
Prevents oxidation and reduces potential impurities
High purity maintained by high vacuum environment
Electron beam additive manufacturing performs manufacturing under a high vacuum. Therefore, oxidation of the build and inclusion of impurities can be reduced.
On the other hand, laser additive manufacturing performs manufacturing in an inactive gas environment (atmospheric pressure). In some cases, oxygen and water may remain. Therefore, attention is needed for active metals such as titanium alloy, etc.
03. Backscattered electron monitoring
Real Time In situ Process Monitoring for Defect Detection
BSE image monitoring function
Using our technology as an electron microscope manufacturer, we have developed a BSE (back-scattered electron) image monitoring function. This technology allows for the observation of surface morphology and defects layer by layer by capturing BSEs emitted from an electron beam. It enables visualization of print quality by using electron microscope technology which is difficult with laser additive manufacturing and other methods.
Defect detection during the process
The benefit of the BSE image monitoring function is its real-time detection of defects in the build. Unlike X-ray CT, an additional testing step is not required after building, improving the quality control efficiency. This function acquires a BSE image by irradiating electron beams on the melted surfaces after the melting step. It is aimed at automatic detection of internal defects and deformation of parts built, based on the cross sectional image.
In-situ process monitoring during manufacturing makes it possible to confirm the build quality in real- time.
In the future, the detection accuracy will be improved for various materials. And by melting the build containing defects found during manufacturing again, realization of a build with almost no defects can be expected.
