Math and physics - volume of an object, volume measurement, properties of a flud state of matter (shape of a fluid body depends on a shape of a body it is contained by)
This project is an antry level project into modeling and printing, no skill is required.
Via this project students learns basics operation in modeling program (Autodesk Fusion360 at our school) where they learn basics of sketching and scale.
Then they try to use PrusaSlicer to slice their made STL and compare print times that depends on a settings they try to use.
Outcome of this project is large set of objects of a different volume which are used in other classes as Math and Physics
There is only software required ThinkerCad or Autodesk Fusion360, which allows exact measured sketches.
3D printer is needed, any would do, just needs to be precise(we tried this on an older version a an unnamed printer and results were not as good)
Preparation time should be 1 hour, teacher prepares some exact bodies for demonstration.
Students then maketheir own models. Print time depends on current objects, we used Prusa Mini+ and printed outcome in 2 prints, which each took about 20 hours (some bodies were of a litre volume). Time depends on a structure and thicness of the walls (we used generic PLA and 1,6mm is enough, so it doesnt leak water).
Total time about 3 hours of work (with students) and 40 hours of printing.
At the beginning we get familiar with the Fusin 360 enviroments, camera movement and basic interface properties.
Then we try to sketch
a) sketch a square, circumscribed circle and inscribed cicle. (exact measuremenst should be in place)
b) basic work with extruding some areas (positive and negative axis)
c) stuents try to sketch some simple objects (smiley faces) just to get familiar.
d) stuents calculate desired volume of an object - they choose cube or some block of a rectangular shaped wall
e) students model their object and add a wall to it
f) students try slicing it and play with the parameters
g) teacher puts projects together and print it (for me students wrote specific properties into an name of a stl they uploaded afterwards)
h) project is printed and students are inwited to look at the print itself, how their work grows
i) students take their objects into math(physics classes and validate their calculations.
