			== Development contexts ==

			There are two major development contexts
			* the context of the RepRap project
			* the context of atomically precise manufacturing (APM) aiming at farther out gemstone based nanotech

			The former context will be discussed here on the RepRap wiki. <br>
			For the latter context please visit the pages on the APM wiki here:
			* '''http://apm.bplaced.net/w/index.php?title=RepRec_pick_and_place_robots'''
			* http://apm.bplaced.net/w/index.php?title=ReChain_frame_systems

			Some design constraints originating from the latter design context <br>
			may be surprisingly useful in the former. Some may make not much sense.
