It would be nice to print them solid, but it would just take too long and probably create shrinkage issues. So the question is, what fill percent suffices (in 3D printing you get to specify the percentage of material fill, the rest being air). I called Greg Cottrell and he didn't have any data on prints, but he did have some on the depth rating of different types of buoyancy foam.I did a napkin calculation and it would appear that, at least if the print behaves like foam of similar density, I'm fine. But does anyone have any data on this? Or does anyone have a small pressure test chamber for which we might print some test samples? I would need to test to about 500 psi.</div><div id="yui_3_16_0_ym19_1_1465878569431_2751"><br></div><div>BTW I've updated Shackleton's project page: <a href="http://www.psubs.org/projects/1234567810/shackleton/" target="_blank" rel="nofollow">http://www.psubs.org/projects/1234567810/shackleton/</a></div><div><br></div><div><br></div><div><br>Thanks,</div><div><br>Alec</div></div></div><br>_______________________________________________<br>Personal_Submersibles mailing list<br><a href="mailto:Personal_Submersibles@psubs.org" ymailto="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a><br><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br><br><br></div> </div> </div> </div></div></body></html>
