- Registration opening soon
It is highly recommended that you apply for a course at least 6-8 weeks before the start date to guarantee there will be space available. After that date you may be placed on a waitlist. Courses with low enrollment may be cancelled up to 4 weeks before start date if sufficient enrollments are not met. If you are able to access the online application form, then registration for that particular course is still open.
Additive manufacturing (AM) processes were first demonstrated more than 25 years ago; however, only recently has broad industrial and consumer interest ignited, with potential implications ranging from ubiquitous personal fabrication to disruption of traditional supply chains. The goal of this course is to present a comprehensive overview of AM, spanning from fundamentals to applications and technology trends, and with strong focus on high-performance materials. Participants will learn the fundamentals of AM of polymers, metals, composites, and biomaterials, and will realize how process capabilities (rate, cost, quality) are determined by the material characteristics, process parameters, and machine designs. Application areas including aerospace components, electronics, medical devices, and consumer products will be discussed via detailed examples and case studies. Particular emphasis will be placed on metal- and powder-based AM technologies, and related design principles and process standards to achieve high-performance materials and novel properties via AM. Lab sessions will provide hands-on experience with a variety of state-of-the-art AM equipment. Participants will design, fabricate, and measure test parts, and will perform experiments to explore process limits. The course will conclude with discussion of how AM will influence existing business models in design and manufacturing, will pose major opportunities and needs for advancement.
- Learn the fundamentals of additive manufacturing (AM) of polymers, metals, and ceramics, along with those for emerging materials (e.g., nanocomposites, biomaterials) and complex architectures.
- Understand the operating principles, capabilities, and limitations of state-of-the-art AM methods, including laser melting, fused deposition modeling, stereolithography, and jetting.
- Understand the principles of "Design for Additive Manufacturing" and compare and contrast additive processes with conventional manufacturing methods such as machining and molding in terms of rate, quality, cost, and flexibility.
- Gain hands-on experience with a variety of AM machines; use these machines to fabricate example parts, post-process the parts, and study the results.
- Become familiar with the complete workflow of AM, including computational design tools, file formats, toolpath generation, scanning, and microstructure characterization.
- Study applications of AM across industries, including aerospace/automotive, medical devices, energy, electronics, and consumer products.
- Via examples and case studies, understand how to quantitatively assess the suitability of AM for an application, and realize how this justification will change as AM improves.
- Place AM in the context of the evolving manufacturing infrastructure, including advances in robotics, software, logistics, and digitization of data.
Who Should Attend:
This course will be useful to design engineers, manufacturing engineers, product designers, research engineers, research scientists, managers, VPs of product development and manufacturing, and technology and innovation strategists, from industries such as aerospace, automotive, medical devices, electronics, consumer products, energy, and robotics. The course material is accessible for those new to AM, yet highly comprehensive and valuable for those who already have significant experience with AM.
Laptops or tablets are encouraged for this course.
