3D design and printing laboratory DM-SL>LABO3D

The 3D Design and Printing Laboratory is a practical course aimed at providing students with comprehensive preparation for working with 3D printing technology. The course combines lecture elements with practical exercises, enabling participants to acquire both theoretical knowledge and practical skills in designing, preparing, and executing 3D prints.

The course begins with a theoretical introduction, during which students learn about the fundamental 3D printing technologies, such as FFF/FDM, SLA, DLP, and LCD. The specifications, technological differences, and applications of these technologies in various industries, such as manufacturing, medicine, education, and entertainment, are discussed. Students also gain knowledge about the types of 3D printers available on the market, their construction, operating principles, and key printing parameters.

The next stage of the course introduces students to 3D design using Fusion 360 software. Students become familiar with the software interface and key features that allow them to create three-dimensional models. During practical exercises, participants learn how to design both simple and more complex 3D objects, using parametric modeling functions, solid operations, and basic construction optimization techniques. An important aspect of this stage is preparing models for export in formats compatible with slicing software.

The following part of the course focuses on the process of preparing models for 3D printing using popular slicing tools, such as Cura and PrusaSlicer. Students learn the principles of model slicing, the process of dividing 3D models into layers, as well as how to adjust printing settings (layer height, print speed, support type, number of walls) and optimize printing parameters to achieve high-quality prints. Special emphasis is placed on understanding how individual parameters affect the efficiency, durability, and aesthetics of the print. During the practical exercises, students prepare their designs for printing, independently configuring and testing the slicer settings.

One of the most critical stages of the course is assembling a 3D printer from ready-made components. Students work in teams, which allows them to develop communication and collaboration skills. During the course, students assemble the Creality Ender V2 3D printer, learning about its construction and operating principles. This process includes mechanical assembly, connecting electronic components, and calibrating the printer. Participants learn how to properly level the print bed, set the distance between the nozzle and the platform, and configure the printer's software. While assembling the printer, students troubleshoot potential technical issues, allowing them to better understand the printer's operation and gain valuable hands-on experience working with real devices.

After assembling the printers, students move on to the next stage, which involves independently executing 3D prints. For this purpose, previously designed and prepared models in the slicer are used. An essential part of this task is printing marketing materials featuring themes related to the Pontifical University of John Paul II. Students learn how to monitor the printing process, troubleshoot potential issues (e.g., nozzle clogs, layer shifts), and control the quality of the prints. This stage of the course develops participants' ability to work with production equipment, which can be useful in their future professional careers.

A key highlight of the course is the study visit to the 3D Printing Laboratory at Cracow University of Technology. During the visit, students have the opportunity to explore a variety of 3D printers, including devices operating in FFF/FDM, LCD, DLP, and SLA technologies. The laboratory features more advanced and professional devices than those found in standard workshops. As a result, participants can compare different 3D printing technologies, learn about their advantages, limitations, and potential applications. Additionally, students take part in demonstrations of industrial 3D printers, which allows them to better understand the production processes used by companies involved in 3D printing.

The course concludes with students preparing reports. Each participant must submit three reports covering the 3D design process, model preparation in the slicer, and the execution of 3D prints. These reports must include descriptions of the process, the solutions used, justifications for the choice of printing parameters, photos of the final prints, and an analysis of potential errors and their causes. Each report is evaluated by the course instructor, and the final grade is the average of the grades received for all three reports. Additionally, the final grade is influenced by attendance. Regular attendance and active participation in the exercises can raise the final grade.

The 3D Design and Printing Laboratory allows students to develop key competencies related to future technologies. Students acquire skills in 3D design and prototyping, learn the principles of working with 3D printers, and develop the ability to independently assemble and configure these devices. An essential aspect of the course is fostering teamwork skills, as assembling the printer and executing team projects require collaboration. Students also develop analytical thinking, problem-solving abilities, and experience working with advanced production technologies. The knowledge and skills acquired during the course can be successfully applied in professional careers, particularly in industries related to 3D design, mechanical engineering, manufacturing, prototyping, education, as well as the advertising and marketing sectors.

In summary, the 3D Design and Printing Laboratory is a comprehensive course that combines theory with practice. Participants gain knowledge about the latest 3D printing technologies, skills in designing and slicing 3D models, and competencies related to the assembly and operation of 3D printers. The study visit to the 3D Printing Laboratory at Cracow University of Technology broadens students' horizons and provides insights into modern 3D printing technologies, including industrial systems. The course concludes with the preparation of reports, which form the basis for the final grade. Well-prepared reports, active participation, and teamwork involvement enable students to achieve a high final grade. This course not only develops technical knowledge and skills but also enhances analytical thinking, creativity, and interpersonal competencies, making participants more attractive candidates in the job market.
