Bionic optimized toilette paper roll holder

thingiverse

This project showcases the method for designing a bionic optimized part. What this means is that only the structure is created, which is crucial for stiffness at chosen loadsteps. The part in this project has been optimized as a toilette paper roll holder. With structural optimization, you can save material and enhance your design process. See attached PDF! MakerEdChallenge2 Print Settings: Printer: RigidBot Big Rafts: Doesn't Matter Supports: Yes Resolution: 0.1 Infill: 22% Notes: Please see attached PDF! How I Designed This Any tips and tricks are written in the attached file, so feel free to download it! The PDF file includes step-by-step guidance in both English and German. Easily set up and optimize design -> wrap it -> print it! Please see attached PDF! Custom Section Project: Bionic Optimized Toilette Paper Roll Holder Project Name: The name of the part includes all relevant information :) Overview & Background: I will learn to understand the whole process of innovative CAE-driven product design. Objectives: Students will learn how to create a bionic design as quickly as possible. The keyword is "Lightweight," as shown by our nature. You will learn how to achieve a good compromise between optimization results and wrapped designs. This is very important for their future as engineers or designers. Lesson/Activity: Please see all the information in the attached PDF file. There is a step-by-step manual with all the tips and tricks from my experience knowledge. Setup the Optimization Model Discuss Different Types of Restrictions Vary Fixing Point Positions Vary Symmetry Vary Manufacturing Constraints Vary Thicknesses Analyze the Generated Design Identify Critical Areas Identify Areas to Delete Discuss Geometry Loadpaths Square Thickness Discuss Physics Force Load Reaction Equilibrium Tension Compression Strength Factors That Engineers Consider When Designing Bridges Structural Efficiency Cost Efficiency Aesthetics Stiffness Printability Guide Students Through Selecting/Creating a Model, Either Work in Teams or Individually. Set Model Specifications and Constraints, These Will Depend on Your Time and Resources: Minimum /Maximum Thicknesses Maximum Amount of Filament to Be Used to 3D Print the Design Minimum Amount of Weight the Holder Should Hold Students 3D Print and Mounting Their Design Supervise and Assess Students Testing Their Design Duration: Setup the Optimization Model: 0.5 – 2 Hours Optimization Run: Depends on Chosen Parameters (Explained in PDF File) Wrapping: 0.5 – 2 Hours (Depends on Your Creativity and Desired Quality) Setup Printing Parameters: 0.5 – 1 Hour Printing Time: 36 Hours Stated Out by Cura with Explained Parameters Preparation: Students Should Only Be Interested in Engineering Stuff. You Need the Student License for Inspire/Hypermesh (Contact Altair Inc.), Cura or Any Other C-Code Generator and Last but Not Least of Course a 3D Printer. References: Economics Literature Rubric & Assessment: Student Should Have Setup the Optimization Problem in Inspire and Interpret the Results Right. In the Wrapping Section, You Can See If the Students Come to a Good Compromise Between Optimization Result and Wrapped Design. By the End of the Project, the Student Will Have Designed, 3D Printed, and Tested a Bionic Toilette Paper Roll Holder. Assessment Criteria: Did the Students' Design Meet the Minimum Requirements: Length Width Hold Minimum Weight Did Not Exceed the Maximum Allocation of 3D Printer Filament Can the Student Identify Features of Their Design: Type of Loadpaths (Tensile / Compression Bar) Use of Geometric Shapes Locate Points of Force, Load, Reaction, Equilibrium, Tension, Compression, and Strength Handouts & Assets: As Often Mentioned -> Attached PDF File!!!
