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.

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.

The future belongs to 3D printing. But printers can only create what you can imagine. Al Williams takes you step-by-step through the process of developing a 3D model used to drive a 3D printer to make your design dreams a reality.

Open-Source Lab: How to Build Your Own Hardware and Reduce Scientific Research Costs details the development of the free and open-source hardware revolution. The combination of open-source 3D printing and microcontrollers running on free software enables scientists, engineers, and lab personnel in every discipline to develop powerful research tools at unprecedented low costs.After reading Open-Source Lab, you will be able to: - Lower equipment costs by making your own hardware - Build open-source hardware for scientific research - Actively participate in a community in which scientific results are more easily replicated and cited - Numerous examples of technologies and the open-source user and developer communities that support them - Instructions on how to take advantage of digital design sharing - Explanations of Arduinos and RepRaps for scientific use - A detailed guide to open-source hardware licenses and basic principles of intellectual property

The Numworks calculator is, in several ways, an improvement over the Texas Instruments and Casio calculators. Those other calculators have been with us for several decades now, with only a very, very slow evolution in their capabilities. On the other hand, consider a few of the Numworks progressive new features and its innovative design. The Numworks calculator's keyboard and user interface is modeled after standard game controllers, making its learning curve so much quicker for today's students. The whole calculator is open sourced - even the plastic body can be 3D printed using publicly available STL files. But its support of Python takes its power and usefulness to a whole new level. Python is arguably now the world's most popular programming language, for everyone from beginners to top professionals. Like the Numworks calculator, its learning curve is short due to its leaner, cleaner, simpler syntax. Python, and the Numworks calculator, are both powerful enough to support the efforts of engineers working at NASA on the most demanding calculation tasks, and yet they easily support the ease of learning and first use that greatly aid today's students. MicroPython is a substantial subset of the full Python language, and it's a perfect match for the calculations required by programmable calculators. Learn MicroPython and a person has a huge head start on computer programming at all levels. Other old school calculators use unique, proprietary programming languages that don't serve future educational and workplace requirements. This book is a collection of real-world Python programs written explicitly for the Numworks calculator. Because of the nature of Python, these programs are short, easy to read, easy to enter into your calculator, and most importantly easy to understand. They provide a great way to enhance the computational power of the Numworks calculator, and to help beginners learn a standardized, powerful, and very popular programming language. The programs are organized into subject areas to meet varying interests and goals. A set of money calculations helps students grasp personal finance concepts. Another set of programs covers electronics fundamentals. Two and three dimensional analytical geometry programs support today's game creation challenges, and so on. Most everyone will find programs of interest in more than one subject area.
