Direct Metal Laser Sintering is an emerging 3D printing technology that has great potential to change the way parts are manufactured. To achieve this, it will be necessary to put aside some of the conventional manufacturing design rules, and look for ways to take advantage of the 3D printing manufacturing process. Some benefits of 3D printing, such as reduction of components, can 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 first understand the limitations of the process in order to design accordingly. We will discuss some of these limitations, such as surface finish, internal features, stresses, and support requirements. Knowing how to work around some of these limitations will open up many new design opportunities.
