&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;It is often thought that APM is supposed to be able to produce almost anything&lt;br /&gt;
(often formulated: all allowed structures permissible by physical law)&lt;br /&gt;
including e.g. food, wood, plastics and metal parts but this is surely not the case.&lt;br /&gt;
&lt;br /&gt;
The range of materials and structures targeted actually lies in a very narrow range (see: &amp;quot;[[mechanosynthesis]]&amp;quot;-page). The magic lies in the [[diamondoid metamaterials]] that emulate properties above the atomic level. &lt;br /&gt;
&lt;br /&gt;
This is not to say it will be impossible for all times to assemble materials (or rather compounds) lying outside the narrow set of now targeted materials.&lt;br /&gt;
When the technology will have been around for quite a while [[Most speculative potential applications|very advanced extensions]] may be able to do this but this is way beyond the scope of any current day APM attainment project because it is beyond the horizon of useful [[exploratory engineering]].&lt;/div&gt;</summary>
