Course Description

Familiarizes students with Stereolithography Apparatus (SLA) 3D printers; their functions, relevant design applications, choosing between and working with a variety of SLA materials, performing root cause analysis for print failures, and designing successful and repeatable print G-Code for different materials. Introduces SLA printer hardware, maintenance, and common subcategories of SLA printer UV light generation systems. Includes how to identify and fix common hardware and software issues, and how SLA printer technology has changed and improved over time. Focuses on post processing printed parts and safe material handling. Audit available.

Course Outcomes

Upon successful completion of this course, students will be able to:

  1. Identify models with geometry and production requirements best suited to SLA manufacturing techniques.

  2. Demonstrate appropriate machine operation and maintenance.

  3. Measure SLA printed parts and modify printing parameters to meet tolerance specification.

  4. Calculate ideal UV exposure settings for different layer heights and different materials.

  5. Apply safe material, part and waste handling as related to SLA printing

Suggested Outcome Assessment Strategies

The determination of assessment strategies is generally left to the discretion of the instructor. Here are some strategies that you might consider when designing your course: writings (journals, self-reflections, pre writing exercises, essays), quizzes, tests, midterm and final exams, group projects, presentations (in person, videos, etc), self-assessments, experimentations, lab reports, peer critiques, responses (to texts, podcasts, videos, films, etc), student generated questions, Escape Room, interviews, and/or portfolios.

Department recommended assessment strategies:

  • Lecture and in-lab coaching and direct instruction.

  • Full class demonstration of skills.

  • Written exams.

  • Student proficiency through demonstration of learned strategies and skills in industry standard environments.

  • Job readiness based on performance.

  • In class lab experiments and testing using the scientific process with written result reporting.

Course Activities and Design

The determination of teaching strategies used in the delivery of outcomes is generally left to the discretion of the instructor. Here are some strategies that you might consider when designing your course: lecture, small group/forum discussion, flipped classroom, dyads, oral presentation, role play, simulation scenarios, group projects, service learning projects, hands-on lab, peer review/workshops, cooperative learning (jigsaw, fishbowl), inquiry based instruction, differentiated instruction (learning centers), graphic organizers, etc.

Department required activities: Cooperative learning, lecture-lab based experiential learning, guided learning pathways, peer review, hands-on lab, simulation, simulation scenarios, oral presentations.

Department Notes

Safety glasses are required at all times in the manufacturing lab, and are provided for students. Students may also purchase their own safety glasses from a local supplier. Long pants and closed toed shoes are required in the manufacturing labs at all times. Appropriate clothing must be worn to work in the lab (no synthetic materials, ect.). Safety requirements are covered prior to work in the lab.
