If you want to learn about modeling laser additive layer manufacturing (ALM) with the COMSOL Multiphysics® software, then watch this webinar with guest speaker Mark Yeoman of Continuum Blue.

Product manufacturing is dramatically changing with the advent of new ALM technologies, which makes it cost effective, easily available, and readily accessible. One sector that is trying to make full use of this technology is aerospace, where reducing the cost of large components, such as fuselage frames, would help reduce cost and production times, dramatically decreasing material waste and the carbon footprint. Although ideal, ALM has some drawbacks when producing large components economically out of metal alloys, including distortion and residual stresses.

In this webinar, Mark Yeoman discusses some of the work in building a multiphysics model, developed for an aerospace and defence company, to predict and understand laser solid freeform fabrication (LSFF). Continuum Blue developed the model to simulate the coupled, interactive transport phenomena between the laser, powder, and substrate during the laser deposition process. This model was used to find the optimal path, speed, and power of the laser head in order to minimize or eliminate distortion and residual stresses in the manufactured components.

This presentation includes a live demonstration in COMSOL Multiphysics® and a Q&A session during which you can ask questions.
