- Granule still bounces up without really being cut by the blades
- We felt that the blades of the blender can become really hot. So we wondered how
that has impact

10. Blending 1 minute, RepRap waste (±10gram)

Thoughts
The result of shredding the RepRap waste was a lot of small wires, which came out of the
rafts of the prints. The (failed) RepRap printed objects that were also in the waste were
cut into smaller pieces, but still consisted out of large parts.
- We wonder what would happen if we would cool down the material first
11. Blending entire milk bottle, first in 1 piece, then cut into 2 pieces, then
4. Until the blender is able to blend the milk bottle into small pieces.
Input Blender Output
Thoughts
As we expected the first time we blended the material it was stuck, this effect remained
until we cut the material for the fourth time into 8 pieces.
- The blades could not shred the screw thread part of the bottle.
- Small amount of material out of one bottle, what can you make out of one bottle?
- Pieces of the bottle cannot be bigger than the width of the blender
- Can a layer of water keep the material from bouncing up and down and cool down
the metal blades and material
12. Blending 1 minute, couple of large crumpled pieces (±10gram) inside a
blender with water (so that the pieces are just “below” water level,
material floats)
