RE: [rp-ml] Adaptive Slicing

We have been using adaptive slicing for many years. It seems to fit well
with our jetting technology and can save quite a bit of time if the geometry
is appropriate for the technique. It also allows us to reduce the stair step
on small critical features where we want to increase resolution but only on
one or two critical features of the geometry.


I suspect that DLP and SLA technologies are less likely to be users due to
the variations in interlayer adhesion that occur which can lead to part
cleavage and very obvious changes in surface finish at the layer thickness
change point. The more likely commercial candidates for this technique would
be the 3D Systems Projet and Solidscape technologies due to their
inter-layer leveling / milling.

Dear All,


I would be interested to hear views on the use of adaptive slicing
techniques (varying layer thickness) within the RP/RM industry . To my
knowledge, the use of adaptive layering techniques in commercial
technologies is somewhat lacking although there are a number of references
offering alternative mathematical approaches to a common theme (although
many don't appear to put theory into practise!). Perhaps the problem is
linked to reliability / integrity of adaptive slicing algorithms or more
likely - hardware is restricted to a finite number of slice parameters
in which layers can be successfully be created. I am guessing that DLP and
SLA systems might be a good vehicle to test adaptive slicing methods? As
always views of the RPML members much appreciated.


Incidentally I am putting together a literature review!
