Grade 4 STEM Extension Learning Lesson #2

Today’s STEM extension learning lesson with George Spiridis (our STEM extension learning expert) focused on software modelling and layering objects for 3D printing. 🙂

George spoke about G-code (specifically looking at the X and Y axis in G-code) and how the code works to build a 3D object. 🙂

George showed the students a digital vernier caliper to measure the 3D printer’s filament – and even measured one strand of hair which was 0.05mm.

At the end of the lesson, the Grade 4 students explained what they had learnt in their extension lesson this week. 🙂

Jolene said, “When you are printing on the school’s 3D printer, you are printing with filament at 0.1mm”

“When the 3D printer has printed an object, it uses a support structure to support the print”, Thiseni explained.

Misha said, “I learnt that gears are important in robotics”.

“I learnt that a strand of hair measures at 0.05mm. That’s smaller than filament for a 3D printer”, said Amelia.

Mehran explained that he learnt that “…vernier calipers can measure how long something is – it’s a digital ruler. It ensures measurements precise.”

“When you print using a 3D printer, it needs to have filament”, said Rayhaan.
