Re: Nearly a year of living with my 3d printer now
can i download and print something
That ought not to be missing the point (athough today, it probably is).
It ought to be able to download the CAD details for just about any plastic artefact, so that you can manufacture your own spare for any plastic widget or cover that gets broken. However, it's not in a product manufacturer's interests to make them available. They'd far rather we bought a whole new hairdryer or whatever. Some have even been known to build in weak spots to encourage things to break sometime after the warranty has run out.
Perhaps what is needed is a breakthrough in 3D scanners to parallel 3D printers, so you could just dump your broken pieces into a 3D scanner and then have the computer reassemble the details of a whole one and print it for you. No CAD expertise then needed.
