PHOTO-POLYMER ADDITIVE MANUFACTURING (PAM) PROFESSIONAL SHORT COURSE (UNDERGRADUATE-LEVEL)

Monday, May 9, 2022, 4:00 PM – 6:30 PM

Faculty: Dr. David A Walker, Co-Founder of Azul 3D; Dr. Jason P Killgore, NIST

Who Should Attend?

Attendees for this course should be UV/EB students or professionals who are employed in the polymer or coatings industry, have a basis knowledge set in polymer chemistry and/or photo polymerization, and are interested in developing a deeper understanding of Photo-polymer Additive Manufacturing (PAM) techniques. As a minimum, attendees should have had an undergraduate course in general chemistry, organic chemistry, or some other chemical based engineering/scientific background. The course is designed and scheduled as a follow-on to the UV/EB Professional Short Course and will build upon the concepts and terminology developed within that course; although this course is not a prerequisite for those already versed in basic UV/EB terminology and concepts.

Course Description

This 2.5 hr course is designed to acquaint UV/EB engineers, chemists, and other technical professionals with the fundamentals of photo-polymer additive manufacturing (PAM) at an undergraduate level. This course is both scheduled and designed as a direct follow-on to the UV/EB Professional Short Course and will build upon the concepts and terminology developed within that course. The PAM Professional Short-Course will review various types of additive manufacturing processes that employ UV/EB chemistries, with a special emphasis on vat-based PAM techniques (SLA, DLP, and their OEM specific analogs). Specifically, it will cover (i) the general methodologies used in PAM, (ii) the common printing mechanisms used in vat-based PAM, (iii) the role and impact of the light source and light patterning hardware, (iv) details pertaining to bulk material properties in layer-by-layer printing processes, (v) a basic overview of key parameters for formulating 3D printing resins (resin analysis, viscosity, additives, etc.), (vi) an overview of post-processing challenges and technologies, and (vii) an overview of part analysis and post-processing analysis. The session will include brief discussions on a wide range of applications and give opportunities for a highly technical Q&A session.

UV/EB Professional Short Course (Undergraduate-Level)

Monday, May 9, 2022, 1:00 PM – 4:00 PM

Faculty: Dr. Mike Idacavage, Radical Curing, LLC, Dr. Neil Cramer, Arkema-Sartomer Americas

Who Should Attend?

Attendees for this course should be UV/EB professionals who are employed in the polymer or coatings industry but who have not had an extensive college-level course in polymer chemistry or photo polymerization. As a minimum, attendees should have had an undergraduate course in general chemistry and at least one semester of organic chemistry.

Course Description

This half day course is designed to acquaint UV/EB chemists and other technical professionals with the fundamentals of polymer chemistry at an undergraduate level. It will involve an overview of step-growth and chain-growth polymerization processes with special emphasis on the latter. Specifically, it will cover the chemistry of free-radical and cationic polymerization processes including kinetic and thermodynamic aspects of the subject. The session will include a detailed discussion of the chemistry of the photo initiation process and will highlight a variety of polymer characterization techniques for UV/EB polymers. In addition, formulation strategies for UV and EB curing will be discussed along with brief discussions on a wide range of applications.

Advanced Photopolymerization Topics (Graduate level)

Monday, May 9, 2022, 1:00 PM – 5:00 PM

Faculty: Dr. Susan Bailey, Michelman; Dr. Molly Hladik, Michelman

Who Should Attend?

Attendees for this course may have extensive polymer or chemistry backgrounds who looking for an introduction into radiation curing. Alternatively UV/EB professionals that have experience in the field but are looking to gain new depth would also benefit.

Course Description

This course will begin with a brief review of photochemical and polymerization processes in UV/EB chemistry. From this common language, we will explore the implications of pigments, radiation sources, and environmental conditions on the cure reaction and performance of the final product. By focusing on the reactions and structure-property relationships, ways to understand and control the final product properties will be discussed. In addition to photo-initiated radical polymer chemistry, cationic, thiol-ene and hybrid chemistries will be used in examples. The course will cover implications for developing applications in low migration materials as well as requirements for inkjet, 3D printing and LED curing.

Design of Experiments for UV/EB Scientists and Engineers

Pt 1 – Tuesday, May 10, 7:00 PM – 9:30 PM
Pt 2 – Wednesday, May 11, 12:00 PM – 2:30 PM

Faculty: Dr. Allan Guymon, University of Iowa

Who Should Attend?

This course will provide the foundation and motivation for using Design of Experiments to improve and optimize UV/EB curing processes and formulations. Students attending the course do not need previous experience in Design of Experiments or statistics. The course is appropriate for individuals with backgrounds ranging from technicians to Ph.D. scientists and engineers.

Course Description

Design of Experiments (DOE) is a powerful technique that allows the maximum amount of information to be obtained by performing the minimum number of experiments. For those in production, product design, or quality control, knowledge of DOE can dramatically enhance effectiveness in solving problems and optimizing systems. Most experiments not based on DOE concepts are two-dimensional, i.e. one variable is changed while a response is measured. DOE, on the other hand, varies all of the important variables simultaneously and systematically, thereby examining the response(s) in many dimensions.

Even with the great potential of DOE, few are familiar with its concepts. The goal of this course is to provide the basic tools needed for DOE implementation in the UV/EB industry. While DOE is based on statistical principles, primary emphasis will be placed on practical aspects in using and applying DOE techniques and on the motivation behind using DOE. Specific topics that will be addressed include:

Background and History of DOE
Steps in a DOE
DOE Terminology
Screening Designs
Model Building Designs
Mixture (Formulation) Designs

CEU Credit

Attendees taking this course will receive 0.6 CEU credits from the University of Iowa. CEU credit forms will be handed out to students the day of the course
