pro-beam additive GmbH announces two 3D Printing processes based on electron beam

pro-beam additive GmbH is a company that debuted in the AM industry last year with the official launch of WEBAM (Wire Electron Beam Additive Manufacturing) and EBM (Electron Beam Melting); its electron beam processes. With strong expertise in electron beam technology, the machine manufacturer brings its solutions to the market under the motto “E-Beam Additive goes Industrial”.

The solution and systems partner announces today the readiness of two systems based on these processes: the wire-based PB WEBAM 100 and the powder bed-based

The former is designed for large components whereas the latter can achieve maximum process productivity.

We are proud to launch our AM systems, in which we integrated our technological and plant engineering-specific expertise,” says Dr. Thorsten Löwer, CTO at pro-beam, adding “With these machines, we are addressing all those players who not only use additive manufacturing with the electron beam, but also want to view, understand, seamlessly trace and automatically control the particular process, regardless of whether it’s an industrial company, university or institute.”

PB EBM 30S powder bed-based system – maximum productivity

Designed for small, highly detailed metal components, the PB EBM 30S is a powder bed that uses the electron beam melting (EBM) process.

With a good resolution and high speed of the electron beam, the machine relies on a unique deposition strategy that enables a controlled and customized heat distribution. Thereby, component size and geometry play a minor role.

Furthermore, due to the “parallelized processes”, the utilization of the chamber can be optimized without significant auxiliary process times; therefore enabling maximum productivity for the customer.

As ongoing quality control is crucial for industrial components, the machine comes with a proprietary technology called ELO (Electron Optical Monitoring) for in-situ monitoring. It generates regular, high-contrast images during the manufacturing process by means of backscattered electrons. With these recordings, it is possible to create a so-called digital twin of the workpiece. The ELO data can also provide valuable information for accelerating and improving the process development, a press release explains.

At the same time, the PB EBM 30S impresses with its open system for viewing and adjusting all process parameters and construction data. This kind of transparency ensures flexibility and enables users to develop their own manufacturing processes that can be reproduced repeatably, pro-beam reports.

PB WEBAM 100 wire-based system – precision in large dimensions

On the other hand, manufacturers that are looking to produce large parts can rely on the PB WEBAM 100.

The machine can process various high-performance metals in a material-efficient manner and enables the fabrication of multi-material components.

The robust WEBAM process ensures reproducible quality for a variety of applications: it is suitable for layered structures for both new components as well as structures on existing metal components. The latter is suitable, for example, to repair worn components.

The WEBAM system is available in various sizes and with various kinematics. With high deposition rates (kg/h), this machine enables fast provision of near-net-shape workpieces. The wire feeder developed by pro-beam, which is integrated into the control system, also makes a major difference. It enables a precise setting of the wire feed as well as a simple and flexible integration of the wire feeder data with the process data. Like the EBM system, the wire-based PB WEBAM 100 also operates with an open system that allows the access to all parameters and their individual coordination.

 The new machines optimally respond to the industrial requirements for an efficient production of 3D printed metal components, the company states in a press release.
