3D printing with RepRap Cookbook

By: Salinas

Overview of this book

A systematic guide consisting of over 100 recipes which focus on helping you understand the process of 3D printing using RepRap machines. The book aims at providing professionals with a series of working recipes to help make their fuzzy notions into real, saleable projects/objects using 3D printing technology. This book is for novice designers and artists who own a RepRap-based 3D printer, have fundamental knowledge of its working, and who desire to gain better mastery of the printing process. For the more experienced user, it will provide a handy visual resource, with side-by-side comparisons of the two most popular slicers, Skeinforge and Slic3r. A basic understanding of designing and modeling principles and elementary knowledge of digital modeling would be a plus.

Introduction

In this chapter, we'll look at how we can increase a model's resolution using a laser 3D scanning process.

We'll do this with a 3D scanning system called DAVID Laserscanner. DAVID is a program that utilizes an ordinary line laser and a web camera to scan an object and then takes this information and interpolates a 3D surface. It's a different process compared to what we used with 123D Catch. Instead of photographing an object from all sides, we'll rotate the object by 360 degrees and capture all the sides with a webcam video, as we move a laser line across its surface. Behind the object, a calibration screen that contains a grid of points is placed. The size of the calibration panel will depend on the size of object to be scanned—the larger the object, the larger the calibration panel. We'll find that this limitation can be overlooked when comparing the DAVID scanning results of smaller objects with 123D Catch. 123D Catch works well when...
