1. Can i print one thing with 2 or more materials?
(ex. steel exterior, with plastic coating inside.)
2. How food-safe is metal? Would a salt container be toxic?
3. what about pepper? Razz

1. Not with Shapeways at present;

2. Only the glazed ceramic is food safe.

If you are holding the salt for decorative purposes, yes. If you plan on using the salt, only ceramics is certified food safe.

Remember that salt is hygroscopic, i.e. attracts moisture. The end result with shapeways' "stainless steel"
material would be interesting corrosion effects from both the sintered steel and the bronze filler - probably
reddish-brown, green and blue salt, maybe nouvelle cuisine but not food grade.
Silver might work, but would surely be quite expensive. Also the required minimum wall thickness would
probably lead to heavy, clunky objects. Strong&flexible plastic (nylon) sealed with a food-safe lacquer (some
people here have suggested types used for winery equipment) is probably your best bet, but I doubt you will
get official approval from shapeways for this.

Silver would surely be expensive. And it would still corrode - containers for salt traditionally had glass liners or else were gilded to prevent this.

But the objects themselves would be less heavy or clunky than in Stainless or ceramic:

Min Wall Supported: 0.6mm (Regular), 0.8mm (Glossy & Premium)
Min Wall Free: 0.6mm (Regular), 0.8mm (Glossy & Premium)

Not sure - that item is for food that brings its own eggscellent food safe container... unless you refer to the accumulated spam in the blog comments, which is probably for decorative purposes. Confused

Wait, What do you mean by "getting Shapeways approval"?
is it just the wall thickness thing?

Getting shapeways to confirm that anything other than their glazed ceramics is "certified food safe".
Nothing to do with wall thickness, but with porosity and chemical resistance.
