3D Printing Designs: The Sun Puzzle

By: Joe Larson

Overview of this book

Jigsaw puzzles derive their name from when they were cut from wood sheets using a hand-woodworking tool called a jig saw back in the 1760s. Have you ever wondered how a model idea for a jigsaw puzzle is articulated, and how it was made with these traditional tools? Through this book, you will master the techniques of designing simple to complex puzzles models for 3D printing. We will quickly introduce you to some simple and effective principles of designing 3D printed objects using Blender. Through the course of the book, you'll explore various robust sculpting methods supported by Blender that allow you to edit objects with actions such as bends or curves, similar to drawing or building up a clay structure of different shapes and sizes. Finally, when the model is sculpted, you'll learn some methods to cut the model and carve out multiple pieces of perfectly-fitting edges of different geometries to complete the puzzle. ------------------------------------------- Note from CM - [Page count: 60] [Price: $9.99 eBook | $19.99 print]

The anatomy of a print

Now that the mechanics of FFF 3D printing are clear, it's time to take a look at how a print is built. If an FFF print is stopped partway through, or observed during printing, the following can be seen:

The following are the different parts shown in the preceding image:

  • Layers: FFF prints in layers, with each layer sitting on the one below it. Prints can be made with thicker layers so that they print faster or thinner layers so that they look better.

  • Outlines: When starting a layer, the outline of that layer will usually be printed first. FFF prints often have two or more outlines so that the outside of the print is strong.

  • Infill: once the outline is done, the rest of the layer is filled in. If an area of the print will not be seen from the outside when the print is done, a loose infill is used to save material and give layers above something to sit on. Top layers are filled in completely. Most FFF prints are largely hollow.
