Ice prototyping

Re: Ice prototyping

Some of my projects involve several types of polymer based rapid prototyping.

Unless I'm missing something here, the ice parts aren't going to be the same shape after a few days in the UPS.

Re: Ice prototyping

The problem with ice is that these parts need to be measured, inspected and handled to judge if the designer, engineer and computer program are all doing what they are supposed to.

The reason for rapid prototyping is to be able to inspect an article before committing to the expensive phase of producing tooling for production.

Of course this is all in my narrow minded view of how things should work.

"Accuracy of the final metal casting is improved by at least 10%. Water is also less expensive, safer to use and more environmentally friendly than wax or foam (for example, wax costs $2 - $3/lb., while water plus required additives costs $0.05 cents/lb. Using water speeds the process, saving time. Water also flows freely and does not need to be injected at high temperatures o pressure (like wax) or blown into molds (like foam). Equipment and labor costs associated with lost wax or foam processes are reduced by up to 50%."
