Understanding Openscad

OpenSCAD is not like other CAD solutions and that is exactly what makes it so flexible and easy to learn. With this book, you will learn how easy it is to develop your own models from scratch in OpenSCAD and then export them for 3D printing or other manufacturing processes. Besides, I'll show you how you can import and process 2D and 3D models from other CAD programs... I will also show you how I approach a design and why I choose a solution for a specific situation. This gives you a practical insight into working with OpenSCAD!

Programming with OpenSCAD is a STEM-focused, learn-to-code book for beginners that introduces core computational thinking concepts through the design of 3D-printable objects. Develop coding skills as you build increasingly complex 3D models and print them into fun games, puzzles, and more. OpenSCAD is freely available open source software that enables nondesigners to easily create 3D designs using a text-based programming language. It’s a great language for beginners because the instant 3D visualization gives you immediate feedback on the results of your code. This book channels OpenSCAD’s visual benefits and user-friendliness into a STEAM-focused, project-based tutorial that teaches the basics of coding, 3D printing, and computational thinking while you develop your spatial reasoning by creating 3D designs with OpenSCAD. Presuming no prior experience with either programming or 3D design, each chapter builds a scaffolded understanding of core concepts. You’ll start by defining, drawing and displaying geometric primitives with text-based code, then expand your creative toolbox with transformation operations – like rotating, reflecting, scaling, and combining shapes. As the projects become more sophisticated, so will your programming skills; you’ll use loops for replicating objects, if statements for differentiating your designs, and parameterized, self-contained modules to divide longer scripts into separate files. Along the way, you'll learn 3D printing tips so that you can produce physical mementos of your progress and get physical feedback that lets you correct mistakes in real time. In addition, the book provides hands-on and accessible design exercises at the end of each chapter so that you can practice applying new concepts immediately after they are introduced. You’ll learn: Programming basics like working with variables, loops, conditional statements, and parameterized modules Transformation operations, such as rotate, reflect, and scale, to create complex shapes Extrusion techniques for turning 2D shapes into elaborate 3D designs Computational-thinking concepts, including decomposition, abstraction, and pattern recognition OpenSCAD’s Boolean, Minkowski and hull operations for combining multiple 3D shapes into one 3D design fundamentals, like navigating the xyz-axis, orthogonal vs. perspective views, and constructive solid geometry Organizing bigger designs into separate files to make code more readable and collaborative Accessibly written for a wide audience (advanced middle schoolers, high school students, college students, artists, makers and lifelong-learners alike), this is the perfect guide to becoming proficient at programming in general and 3D modeling in particular.

OpenSCAD is a free open source software for the creation of three-dimensional geometries. In contrast to common CAD systems such as Fusion 360 or SolidWorks, geometries in OpenSCAD are defined by a purely textual description. This means that all elements of a geometry are inherently parameterized and can be easily adapted. This high flexibility makes OpenSCAD particularly suitable for the design of technical systems and and their components, for example in the context of 3D printing. The book Mastering OpenSCAD introduces you to all important concepts and functionalities of OpenSCAD. The book guides you through 10 selected projects step by step, each project focusing on a limited set of functions and concepts. After these 10 projects, you will know all practically relevant features of OpenSCAD. For the sake of completeness, a final chapter briefly presents the functions that were not addressed in any of the projects.

Although 3D printing technologies are still a rarity in many classrooms and other educational settings, their far-reaching applications across a wide range of subjects make them a desirable instructional aid. Effective implementation of these technologies can engage learners through project-based learning and exploration of objects. Interdisciplinary and International Perspectives on 3D Printing in Education is a collection of advanced research that facilitates discussions on interdisciplinary fields and international perspectives, from kindergarten to higher education, to inform the uses of 3D printing in education from diverse and broad perspectives. Covering topics such as computer-aided software, learning theories, and educational policy, this book is ideally designed for educators, practitioners, instructional designers, and researchers.

Education has changed dramatically in recent years as educational technologies evolve and develop at a rapid pace. Teachers and institutions must constantly update their practices and curricula to match this changing landscape to ensure students receive the best education possible. 3D printing has emerged as a new technology that has the potential to enhance student learning and development. Moreover, the availability of makerspaces within schools and libraries allows students to utilize technologies that drive creativity. Further study on the strategies and challenges of implementation is needed for educators to appropriately adopt these learning practices. The Research Anthology on Makerspaces and 3D Printing in Education considers the benefits these technologies provide in relation to education as well as the various ways they can be utilized in the classroom for student learning. The book also provides a review of the difficulties educators face when implementing these technologies into their curricula and ensuring student success. Covering topics such as educational technologies, creativity, and online learning, this major reference work is ideal for administrators, principals, researchers, scholars, practitioners, academicians, instructors, and students.

Python is an easy to learn, yet very diverse and powerful programming language and that for the language of choice for many hackers. Learn to write your own tools and use them on Kali Linux to see how hackers attack systems and exploit vulnerabilities. Developing your own tools will give you a much deeper understanding of how and why attacks work. After a short introduction to programming with Python, you will learn to write a wide variety of hacking tools using many practical examples. You will quickly find out for yourself how terrifyingly simple that is. By integrating existing tools such as Metasploit and Nmap, scripts become even more efficient and shorter. Use the knowledge you have gained here to test your systems for security holes and close them before others can take advantage of them!

Geometry, of all the branches of mathematics, is the one that is most easily visualized by making something. However, it is all too easy to reduce it to reams of formulas to memorize and proofs to replicate. This book aims to take geometry back to its practical roots with 3D printed models and puzzles as well as demonstrations with household objects like flashlights and paper towel tubes. This is not a traditional geometry textbook, but rather builds up understanding of geometry concepts while also bringing in elements of concepts normally learned much later. Some of the models are counterintuitive, and figuring out how and why they work will both entertain and give insights. Two final chapters suggesting open-ended projects in astronomy and physics, and art and architecture, allow for deeper understanding and integration of the learning in the rest of the book.

This book is for Makers, Engineers, and anyone who wants to create 3D shapes for 3D printing or manufacturing.OpenSCAD has some great advantages over other software you might choose to use. It's free, runs on Windows, Macs, and Linux machines, has a much shorter learning curve, and it puts you in control of your designs instead of your designs controlling you!Using a fun, recipe-like pattern, this book guides you through simple 3D designs that cover 99% of the operations and techniques used day-to-day with OpenSCAD. You'll be baking and making in no time at all! Guidance is provided where you might need some of the more obscure features of the language, but the focus is on fast and efficient learning of the core basics.OpenSCAD works in a different way compared to the expensive commercial software packages typically used for 3D design. Instead of interactively choosing from a multitude of obscure, hard to remember icons, buttons, menus, and sub-feature options to sketch out your designs with a mouse, OpenSCAD lets you edit a text-based script that creates your 3D objects. You get the best of both worlds, because you can easily pan, rotate, and zoom to see your creations in space, but the creation of those shapes is much more in your control and understanding.Contents: Getting Started Why Use OpenSCADInstall OpenSCADCheatsheetHow to Learn from this BookRecipe 1: Hello World Meatball!
