{"doi":"10.18260/1-2--40588","title":"A Framework for Implementing Design for Additive Manufacturing Methods in First-Year Engineering Curriculum: Investigating the effects of specialized training on engineering design and student self-efficacy","abstract":"Additive manufacturing (AM) is widely used in various industries and has transformed the way products are designed and manufactured.Training workshops in conjunction with a part assessment framework encourage designers to use design for additive manufacturing (DfAM) considerations during the process of idea generation.In this respect, a training framework will assist researchers, educators, and students to evaluate and improve designs and encourage exploration of changes that need to be made during the design process.Successful implementation of DfAM considerations in engineering design classes are an important step in preparing students for professional careers.This research investigates the effect of DfAM integration in engineering curriculum on student design in the first-year engineering classes.Students are given a pre-intervention survey to gather information on their self-efficacy and prior experience with AM.Students complete a design challenge prior to the DfAM educational intervention that is then offered in the form of a design workshop in conjunction with a brief lecture.Ideas generated are collected and assessed using an assessment framework that encourages the use of DfAM considerations.Parts are scored on a scale of 1 to 4 in the following categories: part complexity, assembly complexity, number of separate parts, functionality, thin/smallest feature size, smallest tolerance, unsupported features, support material removal and the largest build plate contact.A score is generated and assigned to each design pre and post intervention.A post intervention survey is given to participants to gather information on changes in DfAM self-efficacy after the intervention as well as to gather feedback on suggested improvements and usefulness of the intervention workshops.The student outcomes before and after intervention are collected and compared for improvement in use of DfAM concepts.Gender differences are also investigated.Results show that DfAM educational intervention improves design scores and student DfAM self-efficacy.These results will enable educators to incorporate DfAM workshops in the engineering curriculum.","journal":"Papers on Engineering Education Repository (American Society for Engineering Education)","year":2024,"id":486648,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":3,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9585,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2024-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1330833,"name":"Joseph Ekong","orcid":null,"position":1,"is_corresponding":false},{"id":1330438,"name":"Seyed A.
