Motion and Path Planning for Additive Manufacturing (eBook, ePUB)

• Format: ePub

Produktbeschreibung

Motion and Path Planning for Additive Manufacturing takes a deep dive into the concepts and computations behind slicing software - the software that uses 3D models to generate the commands required to control the motion of a 3D printer and ultimately construct objects.

Starting with a brief review of the different types of motion in additive systems, this book walks through the steps of the path planning process and discusses the different types of toolpaths and their corresponding function in additive manufacturing. Planar, non-planar, and off-axis path planning are examined and explained. This book also presents pathing considerations for different types of 3D-printers, including extrusion, non-extrusion, and hybrid systems as well as 3- and 5-axis systems.

Engineers, researchers, and designers in the additive manufacturing field can use this book as a reference for every step of the path planning process, as well as a guide that explains the computations underlying the creation and use of toolpaths.

• Outlines the entire toolpath planning process required to go from a computer-aided design (CAD) model to G-code that a 3D printer can then use to construct a part
• Defines the terms and variables used in slicing and other path-planning software
• Highlights all the available kinematic arrangements for motion systems in additive manufacturing as well as the advantages and risks of each method
• Discusses the nuances of path planning for extrusion, non-extrusion, and hybrid process as well as 3- and 5-axis additive systems
• Provides an up-to-date explanation of advancements in toolpath planning and state-of-the-art slicing processes that use real-time data collection

Autorenporträt

Alex Roschli obtained a Bachelor's and Master's Degree in Electrical Engineering from the University of Tennessee in 2015 and 2016, respectively. He has conducted research in the Manufacturing Demonstration Facility at Oak Ridge National Laboratory (ORNL) since 2012. His area of expertise and research has centered around the development of large format additive manufacturing and the BAAM (Big Area Additive Manufacturing) system. He has played an integral role in many projects such as 3D printing the first car, a Shelby Cobra, a Guinness World Record holding Boeing 777x wing blade mold, a wind turbine blade mold, and a 34' catamaran boat hull mold.

His current focus is software development for toolpath generation in additive manufacturing. This includes slicing, printing, motor and extrusion control, and closed loop data feedback. Alex manages development of ORNL Slicer 2, a novel toolpath generation software produced at ORNL.
