[Imc-makerspace] Purchase Proposal (Not entirely tongue-in-cheek)

[Stewart Dickson]

Models of open-source manufacturing:  Waffle iron with removable plates,
Mattel Creepy Crawlers, Vac-U-Form

And fun, too!

Waffle iron is physically equivalent to injection-casting expanding
urethane foam, but for the endothermic/exothermic curing/cooking process.
Is the SoliDoodle big enough to build waffle iron plates?  (Missing step is
casting the plate pattern from the SoliDoodle into metal.)

Build a mold pattern on the SoliDoodle, then transfer it to oven clay for
Pewter casting.   I see no reason that Creepy Crawler molds can't be made
out of Pewter.
Is Pewter high-temperature enough to use in a waffle iron?   (Too much lead
for contact with food?  In the 21st Century? -- It was certainly considered
OK for the 18th C.)

Again, patterns built with a SoliDoodle are ready-made for the Vac-U-Form
-- It was actually the original application for 3D printing.
(Well, the industrial-sized vacuum former...)

Build rate on the SoliDoodle is approx. 1 vertical inch/hour.   Reproduce
the parts in a few minutes in Creepy Crawlers or Vac-U-Form.

Cheers,

-Stewart
