In my previous post, I mentioned the responsibility of deciding when to transform a virtual prototype into a physical prototype. I may have been a bit premature having this discussion with my readers. As you may be aware, there is a great deal of hype – surrounding “desktop printing” and I may have jumped on that bandwagon a bit hastily. This technology has been around for decades. True, some very industrious individuals brought this technology main stream by offering desktop printers within a price point of a personal computer. However, before you get to play with this new toy, you must have a “solid model”. While there are many tools to create solid models, engineering or designing a solid model is a very different undertaking.
