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.

Reviewing the print results

Both the slicers, with their default settings, printed well with minor to average problems. The major difference between the two slicers was the amount of time it took to compile the results of the G-code. Slic3r is fast in comparison to Skeinforge.

In the following image, we can see that the coin suffers from a lack of detail. It's difficult for 123D Catch to capture fine surface detail.

Reviewing the print results

In the following image, we can see the results of the toy block. There's a lot of distortion caused by the 3D scanning process of the model. Both Slic3r and Skeinforge produced similar printing results.

Reviewing the print results

The 3D scan of the following figure produced a successful result, but both suffer from a common problem encountered in 3D printing. When a complex model has angles of more than 45 degrees, the filament may lose support and sag.

Note

Refer to Chapter 6, Making the Impossible, for a method of creating a removable support. This will eliminate the sagging filament.

Reviewing the print results

The 3D scan of the pyramid was successful, however, both slicers had difficulty with printing the uneven base of the pyramid, as seen in the following image:

Reviewing the print results

Slic3r has an additional issue at the tip of the pyramid. It's distorted is caused by inadequate cooling of filament layers. As each layer is extruded at more than 200 degrees Celsius, there must be an opportunity for each layer to cool for another hot layer to be deposited. The default cooling settings in Slic3r were not sufficient, but in later chapters we'll learn how to optimize Slic3r's cooling features in the following chapters.
