Week 05
3D printing and Scanning :
Individual Assignment
Design and 3D print an object( small, few cm3, limited by printer time) that could not be easily made subtractively
3D scan an object (optionally print it)
Concept Design :
Design a functional whistle simple to 3d print in any FDM or other methods.
A whistle creates a distinct, single-pitch sound by manipulating airflow. When you blow into a whistle, the air is channeled through a narrowing passage called a convergent nozzle. This nozzle accelerates the air, creating a high-speed jet. The length of the whistle's main chamber determines the pitch of the sound produced. A shorter chamber results in a higher-pitched sound, while a longer chamber produces a lower pitch.
With the help of Solidworks software, let us create a simple whistle that can 3d printed,
