consult 8/05

In the last couple of weeks we sat together twice to make final decisions on the DIY prototype, and to discuss research and materials for the medium batch and mass production.
We had decided to use PP as a material instead of the aluminum, because it is much lighter.

Consult (Davy):

• it's contradictory to want a stiff material yet still want to fold it,
• because there are different sizes you'd need different molds, this adds to the cost
• maybe it can be made in different pieces (increase assembly cost but decrease mold cost significantly)
• small/medium batch won't use a mold because it's too expensive
• maybe think of a more modular system
• look for sandwich materials like delight or alucobond (for example used in elevators)

• don't write of a machine on 1 product, it will be used for different products
• cost/hour, maintenance, energy...
• a mold can be written of on 1 product

• for textiles: maybe look at centexbel, or specific producers like sioen
• write down criteria for the textiles
• can be synthetic textiles that you can weld together
• difficult because producers often make products based on clients demands
• often synthetic based fabrics

•  cost calculation: look at the big lasercutter even though the smaller one was the only one available now (scrap is part of product cost)
• for sizes: you can cut the wood in different sizes (doesn't have to be the sizes available at the shop)
• same for PP, hinges (can also be in plastic, make or buy decision)
