Programming with OpenSCAD


Book Description

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.




The Maker Cookbook


Book Description

The Maker Movement is hot, and librarians are eager to participate. Even if you feel restricted by budget, staff, or space, this step-by-step guide will help you turn your library into a creativity center. The Maker Movement is sweeping the nation because it is creative and educational—and a lot of fun. Nonetheless, some librarians have hesitated to incorporate the movement into their programming because their libraries do not have dedicated makerspaces. If that describes you, then take heart. Written by librarians for librarians, this "cookbook" proves that every library is already a MakerPlace and provides you with recipes to make your library come alive with creativity. Easy-to-use, step-by-step guidance helps you create engaging K–8 programs in science and technology, arts and crafts, and home skills that are perfect for the library setting. The menu of ideas is broken into four types of programming. "Appetizers" add a taste of the Maker movement to existing library programs. "Entrees" present full programs for a lengthy one-day event or a short series. "Side Dishes" are programs you can use if you have limited staff, budget, space, or any combination of those. "Desserts" are low-tech programs, suitable for young children. Each "recipe" includes extensions, variations, and curriculum tie-ins that give you even more ways to present the program ideas, whether to a different audience or as part of other related activities. Programs that involve creating a "Balloon Zip Line," a "Zen Garden," or a "Maker Marketplace" will delight library users and generate activity and excitement in your library.




Mastering OpenSCAD


Book Description

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.




Python for OpenSCAD


Book Description

Python is quickly becoming the world's most popular programming language, for everything from quick-and-easy hobbyist calculations to running some of the biggest online websites such as Google, YouTube, Dropbox, Reddit, and many others. OpenSCAD is a powerful 3D modeling language for, among other things, creating 3D printed plastic parts for hobbyists and engineers. This book enables the reader to leverage the power, versatility, and simplicity of Python to enhance and super-charge the already powerful capabilities of OpenSCAD for Makers, Engineers, and anyone who wants to create 3D shapes for 3D printing or manufacturing. Both Python and OpenSCAD are free software tools that run on Windows, Macs, and Linux machines. The symbiotic use of these two tools enables a much shorter learning curve than when using the expensive software packages, and it puts you in control of your designs instead of your designs controlling you! The complete source code Python listing for driving OpenSCAD using easier-to-remember and easier-to-use commands is included in this book, along with creative examples of the use of all new commands. You'll also see how easy it is to integrate these two tools such that you'll see results instantly on your screen when your Python code runs.
