About 5 years ago, the answer (for us) was StrataSys. Don’t know the right answer today. They print in proprietary ABS and soluble support. We’re not a “materials” shop - we’re more worried about “shape” and “robust parts”. So - ABS works for us. Your milage may vary. Of course, these are not “hobbyist” machines. These are “entry level, industrial strength” printers. -- Kenneth Sloan KennethRSloan@gmail.com <mailto:KennethRSloan@gmail.com> Vision is the art of seeing what is invisible to others. > On Apr 15, 2016, at 15:06 , doug moen <doug@moens.org> wrote: > > @Kenneth: What dual extruder/soluble support tech would you recommend as simple and reliable?

Once we moved to soluble support machines (we currently have 3), I started to view anything less as a toy. There’s just so much more you can do when you don’t have to spend all your time dealing with support issues (designing it, removing it, etc.) Most of the things we print simply could not be done without it. > -- > Kenneth Sloan > KennethRSloan@gmail.com <mailto:KennethRSloan@gmail.com> > Vision is the art of seeing what is invisible to others. > > > > > > On Apr 15, 2016, at 13:52 , Ronaldo <rcmpersiano@gmail.com <mailto:rcmpersiano@gmail.com>> wrote: > > > > Kenneth Sloan wrote > >> That’s what soluble support is for! > > > > Right, if you have a double extruder printer! > > > > > > > > -- > > View this message in context: http://forum.openscad.org/restrict-hull-function-to-one-or-two-dimensions-tp16696p17139.html <http://forum.openscad.org/restrict-hull-function-to-one-or-two-dimensions-tp16696p17139.html> > > Sent from the OpenSCAD mailing list archive at Nabble.com. > > > > _______________________________________________ > > OpenSCAD mailing list > > Discuss@lists.openscad.org <mailto:Discuss@lists.openscad.org> > > http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org <http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org> > > > _______________________________________________ > OpenSCAD mailing list > Discuss@lists.openscad.org <mailto:Discuss@lists.openscad.org> > http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org <http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org> > > _______________________________________________ > OpenSCAD mailing list > Discuss@lists.openscad.org > http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org
