Environmentally Friendly Design of High-Voltage Power Supply for Electron Beam 3D Printing

The environmentally friendly design of the high-voltage power supply for electron beam 3D printing should run through the entire life cycle, from material selection, energy consumption optimization to waste recycling, to minimize environmental impact. Traditional high-voltage power supplies have problems such as non-degradable insulating materials, high standby power consumption, and high noise of heat dissipation systems, which do not conform to the development trend of green manufacturing. Therefore, environmental protection design needs to focus on multi-dimensional technological innovation.
At the material level, recycled modified epoxy resin is preferred as the insulating medium, with a dielectric loss value ≤ 0.002, and the material can be recycled through chemical depolymerization after disposal; the shell is made of lightweight aluminum alloy instead of traditional cast iron, which reduces material consumption while reducing carbon emissions during transportation, and the weight is reduced by more than 30% compared with traditional designs. Energy consumption optimization is the core. By adopting the LLC resonant topology, the power conversion efficiency is increased to more than 92%, and the standby power consumption is controlled within 5W; for the intermittent working conditions in the printing process, an intelligent sleep mechanism is designed. When the equipment pauses printing for more than 10 minutes, it automatically switches to the low-power mode, which can reduce annual power consumption by 150-200kWh.
The heat dissipation system adopts a combination of natural heat dissipation and heat pipes instead of traditional fan heat dissipation, eliminating noise pollution (operating noise ≤ 45dB) and avoiding maintenance costs caused by fan failures; at the end of the life cycle, a modular disassembly structure is designed, and key components such as power modules and control boards can be disassembled and recycled separately, increasing the material recovery rate to more than 85%. In addition, electromagnetic radiation is reduced by optimizing the circuit layout, meeting the GB/T 17799.3 electromagnetic compatibility standard, and further reducing interference to the surrounding environment.
The environmentally friendly design not only reduces the environmental load of the power supply throughout its life cycle, but also provides technical support for electron beam 3D printing equipment to enter fields with strict environmental requirements such as green factories and medical treatment, conforming to the development direction of the manufacturing industry under the "dual carbon" goal.
