Marry a man with calloused hands - Calloused hands are earned through hard work.
This proverb suggests to woman to find a man who has an excellent work ethic.
Design for Manufacturing (DFM) is the process of designing products with a clear understanding of how they will be made, using software like Fusion 360 to create accurate and functional digital models. These models guide the production process and ensure designs are ready for efficient manufacturing.
3D modelling involves creating a digital three-dimensional representation of a product or part. In DFM, 3D models are used to test, refine, and prepare designs for physical production through processes like laser cutting and 3D printing.
Laser cutting is a subtractive manufacturing method. It works by cutting away material, usually from sheets of wood, acrylic, or metal, to form precise shapes and components.
3D printing, on the other hand, is an additive manufacturing process. It builds up layers of material, typically plastic or resin, to create a solid object directly from the digital model.
Both techniques require well-prepared models to ensure successful outcomes. Fusion 360 allows for precise design, testing, and exporting of files ready for these modern manufacturing methods.
The first thing you need to do is to create a free educational license. All instructions here. The video on the right explains it.
Make sure you sign in with your school email!
Once you are sorted your status on Fusion360 should change to educational
WARNING
Often school software version does not change throughout the year. This means that if you work on a project on your home computer then the version will not be compatible with the school system and you will need to only work on it on your home computer/own device.
Follow this tutorial to make a simple bedroom in Fusion 360 using basic shapes and simple tools.
Use your imagination and see if you create things further than the basic layout we covered.
Note the size - 4inches is about 10cm.
Learn to trace a shape.....
Your print should be no larger than 100 x 100 x 100mm

Learn how to create your design in Inkscape and then put the sketch in Fusion360. You will then create a realistic 3D model applying the different material options to test your design before Laser Cutting. This is a great skill to have going into senior DT.
You will also learn how to create an exploded animation of your design.
You will learn how to create a 2D design and duplicate it and include slots so that you can turn it into a 3D design laser cut it.
The decoration is to be a maximum size of 100mm x 100mm
You will also learn how to create an exploded animation of your design.

Create a cube representing you and your likes by putting different designs on each face, including one that has your initials. Think about whether you want them cut out or engraved.

The cube is to be a maximum size of 80mm3
You will also learn how to create working drawings from your design.
WORK IN PROGRESS TUTORIAL BEING RE DONE
In the previous tutorial you created a cube and laser cut it. You are going to take the same design but adapt it so it can be 3D printed. The designs will extruded, either internally or externally.
One side needs to have an internal extrude to easily 3D print.
The cube is to be a maximum size of 20mm3
If this is your first time 3D printing, start by understanding the slicing process. Slicing software is essential because it converts 3D models into instructions (G-code) that a 3D printer can understand. These instructions guide the printer on how to build the object layer by layer, including details like movement, material extrusion, and print speed. Each school may use different 3D printers, so confirm the specific equipment and settings required to ensure proper operation and avoid damage.

Or here are a few options:
Use patterns / designs from a culture to create lamp that when on creates amazing light effects. Many cultures have light festivals and this could be something displayed at one of these in the future including the Christchurch inaugural Tīrama Mai lighting event that coincides with Matariki.
The image far right is a laser-cut LED lamps designed by New Zealander David Hakaraia. They look pretty standard when the light is turned off, but when light hits the lampshade it reveals intricately etched patterns that tell the story of the designer’s Maori heritage.
