[PSUBS-MAILIST] printing

[Alan James via Personal_Submersibles]

Hank,you might want to look at this stuff,http://fulcrumcomposites.com/literature/DataSheetTubes.pdf
Thermoplastic composites. That is, normal re-meltable plasticwith fibers in it, as apposed to thermosetting composites (normal fiberglass)Is a lot stronger than just plastic. Haven't done my homework on price &machineability.Alan

Alan,
That is a good option, but it adds a step.  I like the idea of machining out of a lump of plastic. This is a real opportunity to get creative.  I like it!

 Hank,what
 about adding syntactic foam to counter the
 weightor
 make the members out of fiberglass if you really want
 togo that
 way. Concur with Alec about printing. Have a
 friendwith a 3D
 printing business & he has been very
 negativeabout
 printing larger objects.His advice was it was much
 easier&
 reliable to CNC it out of a lump of plastic.Alan

 Alec,
 Thanks' for putting that to bed.  Perhaps
 machining parts from blocks of plastic.  I have some
 experience machining plastic and it was a treat. Deep Rover
 has ABS pipe members with ss liners, the member is the
 cylinder, sweet.

  Hi
  Hank,
  Generally speaking you
  are
 limited to relatively small pieces and they take a long
  time. It is of course not impossible, but most
 likely not
  the most efficient approach, at
 any rate with small printers
  like
 mine. 
  Best,
  
  Alec

 will need two new opposing manipulators.  I am wondering
 if
  it is possible to print the arm
 members.  Is it
  practical?  I am trying
 to create an almost weightless arm
  set
 up.
