In this session, students will learn 3D modeling using Tinkercad software to design a city and made a prototype of it using digital fabrication tools such as the 3D printer can be applied in prototyping to make the design of the city from digital to physical.

What You'll Need

3D Printer

Tinkercad accounts – each account gives access to 8 laptops/students


The Instructions

3D Printing Technology

dIce-breaking activity _ asking them what cities have you visited? Introduction to 3D Printing Technology, engage students in discussions. ( What is a 3D printer? / Have you ever seen a 3D printer? ), and encourage the participants to hold and touch the 3D projects.


Sara is a designer and she want to improve the city for kids that have a necessary need, so she will be glad to get your ideas to help and develop a 3D design for a new city.

Digital Fabrication

Explain the digital fabrication process

It is the process of converting digital files on our computers to physical objects using different tools and machines

What is this machine?

3D Printing Technology

Display a short video about 3D printing and show participants different 3D projects and encourage them to hold and touch the projects.

It is one of the manufacturing techniques in addition, where the pieces are manufactured by printing a layer on top of the other until the final shape is formed.

3D Design

Explain to students the basic features and encourage them to explore the software

creating a 3D representation of any surface or object in 3D space.

Design & Create A City

The student will design a printable model so the first thing students will design is a base and the dimension of it should be 8cm*8cm, after the base the will start to add trees, streets, buildings, towers, and malls.

Lets explore the design software 

.STL file

After everyone finish the design define to students what is the STL file and how we can export it.

An extension of a three-dimensional stereoscopic file consisting of many triangles.


CAM software - Cura

Introduce students to Cura software and show them how to scale the model and set up the printing variables and prepare the model to be ready to print.


  • (Fab-Safety.1): I can safely conduct myself in a Fab Lab and observe operations under instructor guidance.
  • (Fab-Modeling.1): I can arrange and manipulate simple geometric elements, 2D shapes, and 3D solids using a variety of technologies.
