3D Printing and Laser Cutting

More about the book

MODEL RAILWAYS. The technology for 3D printing has been around for many years but now has a rapidly expanding market among hobbyists and home users. 3D printing machines are now affordable for individuals or modelling societies and offer the opportunity to design and build bespoke parts of a model, or even create an entire carriage, wagon body or station building, through an automated process rather than construct them through traditional methods and materials or buy them off the shelf from a manufacturer. The authors take readers through the principles of 3D printing; the benefits to the railway modeller; the do's and don'ts of building structures in the materials available; an overview of the various CAD packages on offer and a simple entry-level tutorial; how to check your 3D printable file to ensure it contains no manifold errors and how to fix these prior to printing; troubleshooting; finishing your 3D printed component
