    I'm just curious as to whether food-safe, microwave-safe and dishwasher-safe materials will be offered at some point. I can see some potential for custom mugs...

    You know you're dedicated when your girlfriend's Christmas present is going to come from Shapeways (assuming I can get those annoying STL errors to go away).

    Actually, the Polyamide (PA) material that is used for Selective Laser Sintering (SLS) (= White, Strong & Flexible) was originally designed for use in dishwashers.

    Subsequently you can put PA parts in your dishwasher to clean them and I was told it is safe enough to even eat it. I dont think the microwave should not be a problem either.

    P.S. Why does this page mess up my keyboard layout? Seems to have changed to UK layout. Incredibly annoying! I´m using firefox.

    Does this mean drinking out of a cup made from this material would be safe?

    good question! We cannot claim it is safe yet. We have to certify not only the materials, but also the production process and we are not there yet. However this is certainly something that has our attention and we want to do.

    SLS uses a laser to melt the plastic together. I don't think it will survive that much heat.

    Drinking from it is probably safe, but it hasn't been tested so there is no guarantee.

    Just because i have been testing this stuff with different chemicals, and my previous knowledge of this type of material, it has a very low chance of causing a reaction, i would say 3% of people at most
    This is because it is a compound closely related to that of Nylon, which is used in the food industry. So if it is not safe then, i guess i shall need a doctor soon =P
    Even though there is a good chance that it will not cause any sort of reaction, i would advise everyone out there that plans to make anything that has to do with edibles, wait for the certification or find one on this material before .

    Any news on the certification? Maybe using it as a mug and drinking hot tea or caffee from it is not 100% safe, because of soluble substances introduced during the manufacturing process, but what about an eggcup, bracelet or biscuit case?

    Hi Frank,

    We are not there yet, but we are working on it.

    It is still too far away to give any indication on when we can deliver.

    Best regards,

    What of the food safety of the metal process?

    Hi Jordan,

    Same thing. We are working on it, but it is quite a complex matter. We need to this right for obvious reasons.

    Best regards,
