Using 3D Printing within my Physics Education through Free Computer-Aided Design Resources Hannah McPherson Bridgewater College hmcpherson@eagles.bridgewater.edu
Outline What is Computer-Aided Design (CAD)? CAD Learning Resources Overview of 3D Printing Process Example Projects in Physics Education
What is Computer-Aided Design? (CAD) Software designed for object creation. Graphic visualization. Greater accuracy than hand-drawn diagramming. 2D Diagramming Floor plans, construction blueprints, electrical layouts, ect. 3D Modeling Object modeling, may lead to 3D printing.
TinkerCAD Beginner level. Create a free account at Tinkercad.com! Class Friendly! Similar conceptual functionality to AutoCAD.
OpenSCAD Intermediate level Encouraged for programming inclined students. Free download to Windows, Mac, or Linux.
AutoCAD Commercial-level Engineering software. 2D and 3D modeling capabilities. Free 1 year student trial. Available for Windows and Mac.
How does CAD help Students? Abstract problem solving: How can I create a given object using these shapes? Familiarity with software commonly used in Engineering careers. Easy to use functionality for visualization of objects.
Learning Resources TinkerCAD TinkerCAD offers free tutorials for trial projects on their website! OpenSCAD mathcodeprint on youtube.com offers a beginner series of tutorials to create using OpenSCAD software. https://youtu.be/oTCu2hCuqfg AutoCAD https://www.mycadsite.com/tutorials.html. Free tutorials, as well as check-in quizzes and sample files, for using AutoCAD in both 2D and 3D design.
From CAD to 3D Printing: How does it Work? 1. Create object in preferred CAD environment. 2. Export object to .stl file. 3. Splice into gCode. a. This splicer is specific to your printer. 4. Print!
Projects within a Physics Education Token Masses Student independently designs objects of various masses. 1g hanger , 2g, 5g. Accurate masses may then be used in lab for extra application.
Projects within a Physics Education Waterwheels Students design waterwheel objects using CAD software. Objects are printed and tested for functionality in lab. Water-wheels should be designed to lift masses when in use. Creating a wheel stand that students must fit their wheels into for testing adds an extra challenge in that designs must be restricted to specific dimensions.
