Have there been any videos or experience with alumide flexing. Like what kind of flex would a 1 mm strip give? Is if 50% of the flex of wsf?
The amount of flex that a 1mm (assuming thickness) strip would give highly depends on its length and width, and which axis you bend it on. Search for "Moment of Inertia" online to find out more From the material datasheets, Alumide seems to be slightly more than 2x stiffer (see the tensile/flexural modulus) than WSF. However, do note that this comes at a significantly lower enlongation-to-break (4% Alumide vs 25% WSF) so if your part is required to yield significantly, then WSF might be a better option. Cheers QX
Alumide is the first and only strip in the material sample kit that snapped just to give you an idea of it's flex.
Thanks, that helps. So for this piece, https://www.shapeways.com/model/142657/canvas_wrap___pattern_ 1.html?gid=ug3024 Look at the video on that page. Obviously I can't flex it like that, but it should flex enough to get on the iPad, yeah?
Hmm, I'd be cautious. Although WSF/Alumide will gain significant flexibility if you heat them up a bit. If you find that the fitment is slightly off, and it might snap if you try and flex the part anymore, put it in a pot of boiling water for a minute or two. It'll soften it up for clipping to the ipad, and go stiff again as it cools. The nylon has a memory, so you shouldn't have to worry about any irreversible warping. That cover will look pretty smart in Alumide. I say go for it.
