The Solar system


The Solar system

By 3D4Kids


3d model information






280x280(max)x100mm overall





Printing time:


Number of pieces:

30 pieces, overall (the number of planets divided in two part for the printing plus the base/support for each of them plus the general base.


The lesson is about designing and printing the Solar system in order to understand and identify the different planets that are part of it, to study their origin and evolution and to explore the space through the planets structure, features and size. Students will also understand the 3D printing techniques.

Learning objectives

The students will be able to:
– Design the solar system with with Rhinoceros or Sketchup or Inventor Educational or with other suitable CAD software.
– Identify the different planets with their name and size.
– Create in their mind a mental map of the solar system.
– Know and locate the right position of the different planets in relation to the sun.
– Know and explore the universe.
– Understanding the solar system structure and Kepler’s and Newton’s law.
– Prepare CAD files to be printed.
– Learn 3D printing techniques.
– Setting the 3D printing file.
– Print the 3D model of a 3D solar system.

Teacher preparation

Preparation about the guided lesson in the classroom. To consider exercises that could be developed during the classroom lesson in order to make the lesson as interactive as possible.

Teacher explanation

– To introduce the topic and the objective (the solar system planets).
– Explain the basic of the 3D software to use e.g. Rhinoceros or Sketchup or Inventor Educational.

– Guided designing of the solar system.
– Explain how to save the file and how to export to the suitable format for the 3D print (.STL, .OBJ…).
– Explain the basics about 3D printing.
– Explain how to set the file on the coding software, Cura.
– Show how to obtain the G-code.
– Explain how to prepare the 3D printer 3D printer for launching works.

Student activity/Steps

– Design the solar system with some sketch and then using CAD software e.g. Rihnoceros or Sketchup or Inventor Educational.
– Saving and exporting to the suitable format, STL. OBJ….
– Select the suitable setting on Cura for printing the solar system.
– Launching the file on the 3D printer.
– Try the design.
– Participate to the exercises proposed by the teacher (both practical and theoretical).
