1 – Aims

The objectives of this 3D printing tutorial are as follows:

• Learning about the technology and technique of 3D printing.
• Knowing about several uses of this technology.
• Creating a model in standard format of 3D printing (STL) from a BIM model.
• Using Cura software to configure printing parameters.
• Printing a 3D object

2 – Learning methodology

The teacher will give an explanation about 3D printing of 10 minutes.

Students will read this tutorial and will watch the video.

Students will follow the steps shown in the video:

Construction of the 3D geometric model (in STL format) from a BIM model.

Configuration of the printing and 3D printing of the part.

To assess the achievement of the practice, each student will write a report.

3 – Tutorial duration

The practice described in this tutorial will be carried out in a computer classroom.

It will last 3 teaching hours.

4 – Necessary teaching recourses

Computer room with PCs with internet access.

Required software: Revit, Cura

Hardware required: Pcs and 3D printer model Creality CR-10S Pro (Type: layer overlay) or others.

Ink for 3D printing: Filament coil.
