Re: alumide on shapeways

Aluminium is not 44 grams cm3 it's a 10th of that, about 4 grams cm3

Re: alumide on shapeways

alu is too soft for discs tbh

Re: alumide on shapeways

like 1cm thick is enough.
anyone ever had bad experience with aluminum in discs

Re: alumide on shapeways

at 10mm thick you *should* be okay. 2mm ti would be better tho

Re: alumide on shapeways

Remember, 3D printing is adding material, Milling is removing material.

I think this is one of the main reasons anything that is 3D printed ends up being quite brittle.

I think for the sake of a spinning weapon on an Ant you could just shape some thin Ti sheet. Can easily hacksaw through 2mm, and although it'll take some elbow grease you can file it into shape and drill it.

Re: alumide on shapeways

I got loads of ti from hazard2.
to make it wider could I have a ti and aluminum sandwitch
can you harden materials like aluminum?

Re: alumide on shapeways

The idea of 3D printing in metal is really appealing, but found this disclaimer on the Shapeways website, so I doubt it would be up to robot combat.

Please note that the materials we use for manufacturing the products make the products suitable for decorative purposes and they are not suited for any other purpose . .

It might be useful for a chassis but probably not a spinning weapon.

Re: alumide on shapeways

Oh yeh, chassis only most definitely.

Alumide is 1.35 g/cm cubed by the way.

finally cheers everyone

Re: alumide on shapeways

PS that's as light as polycarbonate is it weaker than that?

[PJ-27]

Re: alumide on shapeways

PolyCarb is 1.36g/cm, so lighter!

I don't really know anything about Alumide, but Polycarbonate has an incredibly high impact toughness (much higher than that of HDPE) but has it's flaws.

I'd say give it a try!

Re: alumide on shapeways

polycarbonate/alumide
is 4-6mn polycarb enough?

Re: alumide on shapeways

4mm-6mm polycarbonate is fine for amour, just not alll around
