castings shows that the problems may take decades
to resolve. For now, additive manufacturing is cost-competitive only in niche applications — for
instance, those involving plastics. Businesses that
want to plunge into additive manufacturing should
be cognizant of the challenges. Determining whether
it makes sense to invest in additive manufacturing
will require experimentation and learning.
