S11 3D Design
From idea to object
1. Sketch
An idea on paper.
2. Model
You build it in Tinkercad on the screen.
3. Slice
Software cuts the model into layers.
4. Print
The printer builds it layer by layer.
5. Test
You test it and make a better version 2.
In the session you sketch and model. Printing is a next step.
The five moves
With these five moves in Tinkercad you can build almost anything. It is free and you work in your browser, with nothing to install.
1. Shapes
Drag a shape from the library.
2. Size
Type the exact size in millimetres.
3. Align
Line shapes up exactly.
4. Hole
Turn a shape into a cutter.
5. Group
Combine shapes and cut the holes.
Design for printing
Check the units
Work in millimetres.
Strong walls
At least 1.2 mm thick.
Leave clearance
Leave 0.3 to 0.5 mm of room where parts must fit together.
No floating parts
Avoid big overhangs and use bold text.
Your first version is never the last: design, test, improve.
Learning to work in Tinkercad
How you use these five moves in Tinkercad is explained in the separate Tinkercad course. Start with Tinkercad basics. Then pick a challenge: a test-tube rack for HLO or a battery holder for ELECTRO.
3D success checklist
- The units are mm.
- The holes are Hole shapes and the model is grouped (Group).
- The walls are at least 1.2 mm thick.
- There is 0.3 to 0.5 mm clearance where parts fit together.
- There are no floating parts.
- The text is bold.
In your field
HLO: 3D printing can produce lab equipment.
ELECTRO: 3D printing can produce enclosures and holders.
Reflect
Swap laptops with a partner. Give each other one compliment and one improvement. Then discuss:
- Which move in Tinkercad was the hardest?
- What would you change in version 2?
- What would you like to design for your own studies?
