Powder Based Additive Manufacturing Methods LMF/LMD - Comparison, Requirements and Applications
This presentation will introduce the process basics, capabilities and limitations and the required knowledge and equipment to newcomers in the additive manufacturing world. In the field of AM with metal powders the methods Laser Metal Fusion and Laser Metal Deposition are widely used. Each process offers a variety of advantages as well as limitations. Given the high complexity of the medium used, metal powders and lasers, the complexity of the entire process chain requires users to have a broad materials, software and process knowledge to be successful and competitive.

Metal Laser Powder Bed Fusion at LLNL
The development and optimization of laser powder bed fusion is driven by the opportunity to produce net-shape, fine-featured, complex architectures with high material efficiency. Challenges inherent in process optimization are both powder-dominated and materials-specific. Hear our approach towards process optimization through a broad discussion, with the introduction of case studies performed at Lawrence Livermore National Laboratory.

Designing for the Direct Metal Laser Sintering (DMLS) Process
Direct metal laser sintering (DMLS) is an emerging additive manufacturing (AM) technology that has great potential to change the way parts are manufactured. To achieve this, we must put aside conventional manufacturing design rules and look for ways to take advantage of the AM process. Some benefits of AM lead to reduction of weight and quicker assembly times. Complex features and internal channels that are impossible to machine can also be created. It is important to understand the limitations of the process, such as surface finish, internal features, stresses, and support requirements, in order to design accordingly. Knowing how to work around these limitations will open up many design opportunities.
