Industry leader Govi Rao discusses the importance of 3D printing to lighting and the LRC's education on this topic.

Additive manufacturing (AM), more commonly known as 3D printing, is poised to revolutionize the lighting industry. Indeed, the revolution has already begun with a few manufacturers now offering 3D-printed lighting fixtures to the commercial market. Recently, the Biden administration has expressed its support for AM to address supply chain disruptions.

It is expected that 3D printing will offer many benefits in the manufacturing of components for lighting systems, including fabrication of cost-effective unique parts that cannot be made using traditional manufacturing methods.

The Lighting Research Center (LRC) has been conducting research and development activities in the application of 3D printing to lighting since 2015. To share this knowledge and experience, the LRC is offering a five-week, interactive, online course on the application of 3D printing to the design, development, and manufacturing of lighting components and products.

Course Description and Schedule

The course will provide training in the application of 3D printing to the design, prototyping, and manufacturing of lighting system components, and give participants the knowledge and skills needed to begin applying this technology in their own companies.

There will be both weekly, in-person instruction hosted by course faculty (i.e., weekly, approximately 2.5-hour live, interactive sessions), via an internet-based conferencing system (WebEx), as well as supplemental activities and assignments to be completed by course participants throughout the five-week course period. Industry leaders will join LRC faculty to present updates on the state-of-the-art of additive manufacturing technologies .

Course instruction will include collaborative, hands-on activities using physical components and parts provided by the LRC. Course participants will work interactively with course faculty in live, remote laboratory sessions. Participants will also design components that will be additively manufactured at the LRC and returned to participants for evaluation as part of the course sessions.

The course will begin on January 25, 2023, and will run through February 22, 2023. Classes will meet on five Wednesdays from 11:00 AM to 1:30 PM US Eastern Time. A more detailed schedule of course activities, presentations, and assignments will be provided upon registration for the course.

An overview of course content is included below.

Date TBD – Session 1: Introduction to the 3D printing process, including its pros, cons, and benefits as compared to other manufacturing processes. The session will provide an overview of the lighting and 3D printing markets size, trends, and growing applications. Case studies of the current best uses of 3D printing in the manufacture of lighting components and a review of best practices for 3D printing design will be presented. The session will end with a discussion of how 3D printing can support product innovation and differentiation.

Date TBD – Session 2: Comparison of 3D printing processes and technologies, including an overview of the various types of 3D printing technologies and the pros and cons of each in terms of rate, quality, value engineering, and flexibility. The session will also cover availability of materials, material properties needed for lighting products and their certification, and the impact of printing parameters and post-processing on final product finish and lighting design targets. Also to be discussed is 3D object creation with computer-aided design (CAD), including a review of slicing software programs and requirements. As part of this session, each participant will design an optical component. The design will be emailed to the LRC to be additively manufactured and returned to each participant for evaluation in a later course session.

Date TBD – Session 3: Optical component printing, including a review of the printing process for both transmissive and reflective optical components, as well as 3D printing design and fabrication parameter pitfalls, tips, and suggestions. The discussion will start with an introduction to photometry and colorimetry terms and the short- and long-term requirements of optical components for different lighting applications. This session will include a live interactive lesson in which course faculty will lead participants through the measurement and evaluation of 3D-printed optical components. This session will also include short-term and long-term performance characterization of both transmissive and reflective 3D printed components, as well as an interactive discussion session on the optical performance effects due to 3D print parameters, orientation, and post-processing of 3D-printed components.

Following this session, participants will design a fixture envelope that incorporates a combination of optical element, heat sink, and an LED module to create an LED lighting product. The design and the necessary files to 3D print the design will be emailed to the LRC to be additively manufactured and returned to each participant after completion of the course session.

Date TBD – Session 4: The focus of this session will be 3D printed heat sink design and printing, including an overview of thermal management theory, analysis of thermal performance of heat sink components, heat sink build orientation, print parameters, application orientation-related performance, and the effects of LED junction temperature on light output, color, and other factors. Also to be discussed are the short-term and long-term effects of 3D-printed components under environmental stressors. This session will include an interactive lesson on junction temperature measurement and the effects of 3D print parameters, orientation, post-processing on overall thermal peformance.

Date TBD – Session 5: Discussion will be focused on the measurement and analysis of 3D-printed components. This session will include a live, interactive session on photometry and thermal measurements; light output and beam quality evaluations; and LED junction temperature calculation and analysis on the participant-designed fixture envelope with the optical, thermal, and light sources (provided that participants consent to their designs be used for education/demonstration purposes in this session). The class will end with course discussion, review, and a question-and-answer session.
