Regarding these Reprap type machines something has not clicked with me, and surely I can't be the only one.
A lot of parts that are being made on these machines seem to be made purely because they can be, with no consideration being given as to whether its the best way of getting the end result.
One example. Is there any valid reason to make an assembly of 30 separate parts when one flat plate with three holes would do a better job? (One side of the support for the reel holder) The same thought applies to the actual spool, yes it can have nice hexagonal holes for nuts to drop into but it does not really need hexagon holes (it does not even need nuts if the holes were tapped, or better still had the female threads 'printed'
. Having said all that an old empty cable reel is more time and cost effective.
I can see the original concept of a machine that could replicate itself was good (marketing/publicity?) idea, but that was some time ago. What I wonder about is, whether the limit to the accuracy and repeatability of the finished part is already restricted by the media and extrusion process rather than the rigidity of the construction?
