Wood character needed
1.material should be cheap and easy to work with2.easy to burn3.reusable, environmentally-frendly,without poisonous smoke4.easy to carry5.it should be cylindrial(a cylinder or a rectangular solid) and have the suitable size to make manufacturing easily

Final outcome
We choose a piece of wood and chips from a factory far away with the following characteristics:
• 150RMB(wood and chip totally)• pine • a ractangular solid (150*150*1000)mm
• the wood is the best one we can find to satisfy the requirement mentioned above and coordinate the conflicts between different characteristics
StackStickProjectHistory of the conception
History of conception 1/2
• The main idea was to follow our • 3D model plan
• Needed tool would be a lathe with a four-jaw chuck
• On-campus workshop only provides only a three-jaw chuck• Impossible to produce the prototype in the workshop
Block of wood
Four jaw chuck
StackStickProjectHistory of the conception
History of conception 2/2
• Factory-like workshop on campus
• Prototype was impossible to make on a lathe.
• Many different methods for prototyping – but none for wooden produtcs
• It was possible to make a mould with rapid prototyping – too costy and late delivery

Recipe
This is a dangerous production process. The product can easily catch fire.
Attention:
Don't do this at home!

Recipe - Material
- Take candles and smash them
- Mix it with smashed wood
- Shake it

Recipe – Final product
- Take two funnels, one big, one small
- Cut the smaller one as shown on the picture
- Put a little bit of material in a plastic bag. Put everything in the bigger funnel.
- Put a plastic bag on the small funnel and put it inside the big one.
Take plastic that can handle high temperature!

Recipe – Final product
- Finish fulfilling it with material and put it on a cup half filled with water.
- Put it two times 2 minutes in the microwave.
- Put it straight away in the freezer
- Repeat the same operation with a cylinder shape.

Final product
• looks very easy• took several weeks of research
important factors:• exact mixture of paraffin and sawdust• time and temperature for the sintering process• time and temperature for the cool-down process

Final product
Material Cost:Paraffin: 2 YuanSawdust: 0.5 YuanAdditional Items: 0.6 Yuan
3.1 Yuan
Burning Skills• testobjects (10x10mm) could beset on fire like a candle• objects burned for at least 8:26 minutes• no additional components added• very solid and light strukture• safe handling (no explosions possible)• very cheap
StackStickProjectConception
Final product
• production in 2 separate steps
Hat + Tube
• both parts “glued” together
• finaly drilling the hole into the hat

Conclusion
• Prototype burns well• Cheap• Safe
• Standarization for the mixture is needed• Different material needs to be tested• Process of manufacturing needs to be standarized
Project was a succes!
CONPRO
Future Plans:• Finalized chill-mould for perfect production• Different product sizes of the stack stick• Test run with other shapes• Collaboration with other products, i.e. one way BBQ
