For those of you like me, there is always a new invention coming to mind, but these ideas usually just end up on paper and stashed somewhere or forgotten. The ideal of rapid prototyping has been around for many years with very expensive machines that could easily cost 100,000 or 200,000 for basic models, but a few years ago there has been much smaller machines that are powder based verses liquid, that cost much less. Typically there is a laser that slowly solidifies a plastic liquid, or powder that fuses together, both of which were still very expensive. However, recent technology has brought rapid prototyping 3D printers to a more realistic level for consumers. The “Fab@Home” printer is the cheapest 3d printer available today. And not only that, you can build it yourself! There are even 3D Solidworks models available online for free. All you have to do is order the parts and send some of the parts to local machine shops to make the parts and then you have you very own personal 3d Printer!
There are different Fab@Home printer models. The different personal fabrication machines come in 2 different models, a single syringe tool or double syringe tools. Currently the Fab@Home printer is limited to printing gel like substances using only a syringe tool, but future models are expected to also fabricate metallic materials. I find it amazing, but the makers of the Fab@Home printer are confident that in the future you will even be able to fabricate your own batteries, using this similar rapid prototyping technology. But by “rapid prototyping” I mean the machine will do most of the work for you and you just plug things in and get a basic rough idea of what a full production model would look like. Typically rapid prototyping is still very slow relatively speaking. Even with the Fab@Home, it could take 8 hours or more to produce something. For the Fab@Home, most of that time is probably because it has to wait for previous layers to dry first. It looks like The Fab@Home creates a much messier finish than much more expensive models of rapid prototyping machines. Personally I think it needs a lot of improvement, but it looks very cool. I’m not sure I believe it yet, but they claim it’s possible in future versions to create a small robot that would walk out of the machine, and possibly self-replicating robots!
The Fab@Home website says the Model 1 design will cost you around $2300 USD before shipping. That includes all the hardware including a USB interface that you can purchase from various vendors they have already found for you. There are also places to buy pre-assembled models if you like.
