        <description><![CDATA[But &quot;resin&quot; is what fiber-glass is made of.  Well, resin and glass. Ordinary glassing resin is clear and will harden if heated, so laser-ing it with a point focus is an easy way to &quot;print&quot; something.  What results is a plastic part, not fine enough for real jewelry.This would be great for modeling... one could just fabricate the parts, since resins are a common modeling material.  The fabricator would have to be bigger, though.]]></description>

        <description><![CDATA[Resin isn't the only way to go.Selective Laser Sintering can fuse metal powders.So you will one day be able to print gold earrings, steel bolts, etc.The &quot;collector's value&quot; will cease to mean anything, as anybody will be able to own an identical copy.One day...Mona Lisa copies, hanging in every home, identical to the atom with the original.And combining different metals will create super-strong materials.

        <description><![CDATA[The best example was the one provided in the article, the creation of acustom fit hearing aid.  I can likewise see the creation of custom make upas well temporary crowns for teeth, etc.I can also see it being used to fix things.  Someone chips an object and you use this to create an exact fitting component.  Sort of like bondo is used for a car. It would still need finishing, but it would allow for a more intricately shaped replacement to be made.]]></description>

        <description><![CDATA[although, it would probably end up taking months to print one thing if it's at that resolution.  But it would be pretty awesome to have a printer that has all of the base elements in little containers and throw them all together to print out literally anything.  But that's more than a little ways off. :P]]></description>

        <description><![CDATA[Are you saying these &quot;printers&quot; will use silver, for example? That they can use any material they like to print the product? I get the impression they only use this nebulous substance referred to in this article as &quot;resin&quot; and, if so, the question would be: is &quot;resin&quot; better or worse than what the product would have been made of otherwise. I mean we're reading what wonderful things these 3D printers are but what are they really practical for?In the case of furniture, wood is most often the material used. The question is: will &quot;resin&quot; be better or worse than wood as a practical matter? Will it last as long? Will it tarnish more or less easily? Will it ignite more or less easily, etc., etc.In the case of jewelry, it's unlikely this &quot;resin&quot; stuff is going to command the same price as gold or silver. In fact, nobody is likely to want jewelry made of &quot;resin&quot;, even if someone, at some point, adds gemstones. If such is the case, in the matter of jewelry, these printers will create only what goes in bubble gum machines.I'm just trying to find out what stuff that gets &quot;printed&quot; is going to be made of.]]></description>

        <description><![CDATA[Reproductions, whatever the size, will only be practical for things where the physical characteristics of the hardened resin - strength &amp; resistance to heat come to mind - are adequate for the use.  For uses that are visible - such as jewelry - rather than hidden - such as spare parts - the reproduction will be painted or even metal plated before it is put to use.]]></description>

        <title><![CDATA[The answer is, it depends.]]></title>

        <description><![CDATA[Ultimately, all the materials used will do is create a base line of &quot;value&quot; for those materials ability to be reused.For the initial object the cost will be higher because you need to pay for the designers time.  Additional copies or the right to exclusivity will effectthe price since the design cost is spread out.With regards to materials, you are dealing with a completely separate issue.  Jewelry sells for much more than the &quot;melt&quot; value of the raw materials.&quot;Value&quot; will vary depending on the perception of the potential buyers more than the mere materials.  Consider a Baseball card.  One with apopular player sells for much more than one of someone of less popularity even though the materials used to create those cards areidentical.Likewise, the same applies to the art world.  People pay quite a bit for ordinary materials used in &quot;new&quot; ways.  Personally, it seems stupid to me, but that's not relevant.Yes, in all likelihood the one made from gold will sell for more than the one made from silver, given the exact same design and print runs.  But if the silver one is a proto-type of extreme limited edition it may in fact sell for more than the gold, provided there are 2 sufficiently monied collectors willing to fight over it.Some guy spent, I think, $50,000 for a sealed copy of a Nintendo game that was rare simply because it was so terrible that no one wanted it at the time and thus became rare since they were made inlimited quantities and the unsellable remaining pieces thrown away.]]></description>

        <description><![CDATA[I'd like to see an article addressing the material used in these things and how it will effect the quality and value of the object printed (for the non-scientists among us). What I'm interested in knowing is, if furniture is printed on one, what will the furniture be made of (I assume not wood)? This article talks about jewelry. How valuable will a piece of jewelry be if it's made of this &quot;resin&quot;? Exquisite detail is probably less important than whether the piece is gold, silver or &quot;resin&quot;.]]></description>
