E3D+VET exercise: Solar System

myminifactory

This is part of a series of 30 exercises developed during the E3D+VET program. The goal of this Erasmus+ program is to immerse VET centers in 3D printing. This exercise consists of three-dimensional printed spherical models of the star (the Sun) and the eight planets that make up our Solar system, including Mercury, Venus, Earth, Mars, Jupiter, Saturn with external rings around it, Uranus, and Neptune. Each model will have a ring retainer underneath to prevent rolling away. The Sun is printed in a 1:5 billion scale from its actual dimensions, while the planets are printed in a 1:1 billion scale. The Sun and the planets should be printed with different colors to increase their differentiation between them (colors mentioned in brackets should be painted manually). • Sun – Orange • Mercury – Grey • Venus – Brown • Earth – Blue (green land marks) • Mars – Red • Jupiter – Orange (white frames) • Saturn – Yellow (orange rings) • Uranus – Dark blue • Neptune – Purple • Retainers - Black Real diameter dimensions: Printed diameter dimensions: Reduction scale • Sun – 1,391,016 km -> 278 mm -> 1:5 billion • Mercury – 4,878 km -> 4.8 mm -> 1:1 billion • Venus – 12,100 km -> 12.1 mm -> 1:1 billion • Earth – 12,756 km -> 12.7 mm -> 1:1 billion • Mars – 6,787 km -> 6.7 mm -> 1:1 billion • Jupiter – 142,984 km -> 142.9 mm -> 1:1 billion • Saturn – 120,536 km -> 120.5 mm -> 1:1 billion • Uranus – 51,108 km -> 51.1 mm -> 1:1 billion • Neptune – 49,538 km -> 49.5 mm -> 1:1 billion If other sizes are required, they can be recalculated with the Solar System Escalator found at http://www.exploratorium.edu/ronh/solar_system/.
