3D Printed Science Projects Models

myminifactory

This set of models showcases a selection from the book 3D Printed Science Projects, which teaches readers how to modify and explore various scientific topics in depth. To get started, here are seven models that the book teaches you how to create, along with notes on which chapters delve into relevant subjects. Camellia: A model depicting the structure of an average flower is presented in Chapter 6. Truss: This model helps understand forces acting within a two-dimensional truss, as explained in Chapter 8. Wing Model 1 and Wing Model 2: Two classic wing designs are provided on a stand. Although both models have the same cross-section, NACA 2412, one is swept 30 degrees and tapered with a shorter wingspan. Assemble these models by attaching or gluing the two halves together, setting the angle of attack (how the wing points into the airflow). You can then create a "micro wind tunnel" by weighing down the base, placing the entire setup on a postal scale, and blowing air from a fan on it. As the fan blows air over the wing, lift is generated, and the wing apparently becomes lighter as seen on the scale. Two wings are included to demonstrate the range of possibilities that can arise from this basic model, as explained in Chapter 4. Water Molecule: A half-water molecule model allows you to print out quantities and assemble them into ice crystals, which is covered in Chapter 7. Halleys Comet: The base of this model represents the elliptical orbit of Halley's Comet. The height of the model indicates how fast the comet is traveling at that point in its orbit. It accelerates near the sun and slows down when it is far out in the solar system, as discussed in Chapter 3. This model includes a cooling tower to ensure the tall point prints more cleanly. Wedge.stl: A 30-degree wedge is presented for students learning about simple machines, which is covered in Chapter 5.
