TRUMPF: 3D printing large-scale single-block copper components using green lasers

This component is a radio frequency quadrupole (price request)which is one of the most complex components of an accelerator.Price request Providing energy to particle beams, bringing them closer to the speed of light. “There are currently more than 1,000 particle accelerators in operation around the world.30,000most of which are used in the healthcare and industrial sectors. Additive manufacturing can help reduce the size and cost of accelerators by improving their performance by improving the way they are manufactured and shortening their manufacturing time. “CERN of I.FAST project coordinator Maurizio Vretenar explain.

The objective of this strategic project is to enable Europe to develop and strengthen its leadership in the field of particle accelerators, in the service of science and society. advanced accelerator technology I.FAST works coordinatorTom Thorim “It is clear that in the future we will increasingly use components produced by additive manufacturing technologies in the accelerator sector,” noted.

This device uses a green laser to print the finest copper structures with consistently high quality while increasing productivity,”Thielmann explain.

Efficient, partially automated TruPrint 5000 3D Printing systems provide the ideal basis for industrial series production. With optional features including 500°C Warm up and equip three 500 With the full-field multilasers of Vartumkäf fiber lasers, you can cope perfectly with the most demanding industrial applications. The machine produces high-quality components made of different metal materials quickly and reliably and thus meets the high quality requirements of tool and mold manufacturing, especially in 3D Printing on preforms, aerospace and medical technology. As an option, the entire process chain can be carried out under a protective gas atmosphere: screening, printing, cooling, powder removal. In combination with external parts and powder management and monitoring solutions from TRUMPF,

Until now, suppliers have used traditional methods to CERN Manufactured in scientific laboratories and industry Price request. Many separate production steps such as milling and soldering are required, and these processes cost time and money. Additive manufacturing eliminates many intermediate steps. For example, when printing Price request TRUMPF systems can be built around empty spaces such as cooling channels.

Thielmannstates: “Using green lasers to make copper parts is faster than other systems using infrared technology. Copper absorbs green laser beams more easily, making it easier to process. Using green lasers requires less energy to be as fast as infrared lasers can work faster with the same energy, so users can additively manufacture copper components at lower cost using green lasers.
