Free STL files downloaded from Thingiverse can be edited in 3D Slash. It is an easy-to-use software which lets you create models using a simple block building technique, much like Tinkercad. 3D SlashģD Slash is one of the best free cad programs for 3D printing learners. This software can also be used to edit and repair STL files. This tool can be easily attractive to all new learners, enthusiasts, students, and even kids for that matter. You can learn the lessons anytime you want and as many times you want. It starts with basic tutorials and helps you understand all the functionality step-by-step.

That’s where FreeCAD could help out a great deal: it’s sufficiently powerful to produce relatively complex objects, and is available at no charge.īut you may need a book to help get you started on FreeCAD, and this book could be the one. These folks will soon tire of printing other people’s 3D models and want to do their own, but they will be shocked by the pricing of some commercial 3D tools. I’m thinking that as the capabilities of desktop 3D printers continues to increase, we will see more people coming into the technology for the first time. At the end of sections there are questions and exercises to firm up your FreeCAD skills. The remainder of the book explores more advanced techniques, such as generating patterns of objects, creating formal drawings, solid modifications and assemblies, which are designs containing multiple parts.Įach section of the book is laid out in tutorial fashion, with specific examples being explored for each concept. Then you’ll learn how to “dress up” the solids with features such as threaded holes, pockets, etc. The next section of the book deals with how to transform those sketches into 3D solid objects through a variety of techniques included with FreeCAD. Sketching is more complex than one might imagine, but there are plenty of examples of how to create all manner of sketches here. The book then moves on to sketching, a critical function that is used to create curves that are later extruded into 3D shapes.
