This second volume addresses these topics for advanced science fair participants or those who just like reading about and understanding science. 3D Printed Science Project Volume 2 describes eight open-source 3D printable models, as well as creative activities using the resulting 3D printed pieces. The files are designed to print as easily as possible, and the authors give tips for printing them on open source printers.

As 3D printers become more and more common and affordable, hobbyists, teachers, parents, and students stall out once they've printed some toys and a few household items. To get beyond this, most people benefit from a "starter set" of objects as a beginning point in their explorations, partially just to see what is possible. This book tells you the solid science stories that these models offer, and provides them in open-source repositories.
Many people know what 3D printing is and others may have seen one in action or even have printed toys or household items. However, many new users have stalled out after creating a few items, and have trouble going beyond that point. To get past this point, the second volume of 3D Printed Science Projects Volume 2 provides more stories and models involved in open-source repositories.
3D Printed Science Projects volume 2 by Joan Horvath and Rich Cameron describes open-source 3D printable models that can help educational and scientific users learn physics, math, engineering, and geology. This book allows the reader to create a wide range of projects and provides a large volume of information suitable for advanced science fair projects. Each of the eight topics in this book is designed to explore creative activities using 3D printed objects. To download a selection of models for this book, visit 3D Printed Science Project Models.
3D Printed Science Projects Volume 2 - Physics, Math, Engineering and Geology Models This book uses OpenSCAD models to visualize science principles in topics somewhat more advanced than the ones in the first volume, including models of geological strata, snowflakes, probability, moment of inertia, the doppler shift, and more. The models are designed in most cases to be altered by the reader to experiment and improve their understanding of the science topics.
Therapies based on tissue engineering and regenerative medicine are being pursued as a potential solution for the organ donor shortage.1,10 The traditional tissue engineering strategy is to isolate stem cells from small tissue samples, mix them with growth factors, multiply them in the laboratory, and seed the cells onto scaffolds that direct cell proliferation and differentiation into functioning tissues.7,10,13 Although still in its infancy, 3D bioprinting offers additional important advantages beyond this traditional regenerative method (which essentially provides scaffold support alone), such as: highly precise cell placement and high digital control of speed, resolution, cell concentration, drop volume, and diameter of printed cells.10,13 Organ printing takes advantage of 3D printing technology to produce cells, biomaterials, and cell-laden biomaterials individually or in tandem, layer by layer, directly creating 3D tissue-like structures.13 Various materials are available to build the scaffolds, depending on the desired strength, porosity, and type of tissue, with hydrogels usually considered to be most suitable for producing soft tissues.6,7
The heart of the CLIP process is Digital Light Synthesis technology. In this technology, light from a custom high performance LED light engine projects a sequence of UV images exposing a cross section of the 3D printed part causing the UV curable resin to partially cure in a precisely controlled way. Oxygen passes through the oxygen permeable window creating a thin liquid interface of uncured resin between the window and the printed part known as the dead zone. The dead zone is as thin as ten of microns. Inside the dead zone, oxygen prohibits light from curing the resin situated closest to the window therefore allowing the continuous flow of liquid beneath the printed part. Just above the dead zone the UV projected light upwards causes a cascade like curing of the part. 041b061a72
