[PSUBS-MAILIST] printing

[Alan James via Personal_Submersibles]

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.
