STRATASYS
Stratasys, an additive manufacturing supplier,
recommends its PolyJet technology to produce
injection-molded prototypes for testing and design
validation. T his te chnology cre ate s smooth,
detailed and accurate molds strong enough to
hold up to short runs of about 10 to 100 parts,
the company says. PolyJet 3D Printing works
similarly to inkjet printing, but instead of jetting
drops of ink onto paper, the system jets layers of
curable liquid photopolymer onto a build tray.
MARPOSS ARTIS
Marposs Artis showed how a software solution
for in-process tool-condition monitoring works
w i th o u t re q u i r i n g a ny s e n s o r s o r ad d i ti o n a l
hardware to be installed on a machining center.
The software captures multiple axis-motor-driver
s i g n a l s to d e te r m i n e n o r m a l c u t ti n g fo rc e s
such as torque. As these forces change, the
sof tware routines automatically recognize the
underlying condition as tool wear, tool failure or
a missing tool.
