we need to promote
the learning of the
next generation of
engineers, ensuring
they are exposed to
additive manufacturing so that it becomes
as natural to them as
subtractive is to us.
from traditional subtractive manufacturing. As it is an additive method, not only do you design the build
for the final geometry/part but you
design the build with the building
process in consideration too.
For example, when building overhangs or angled geometry, there
needs to be support structures added
to the geometry due to melt pool distortion. Programming parts or geometry in a CAD/CAM takes a great deal
of practice and skill as the programmer essentially creates the opposite
of a traditional tool path.
Traditional machining requires a
certain set of parameters such as feeds
and speeds to achieve good quality
parts within tolerance. Additive manufacturing also requires parameters that
need to be precisely fixed, to achieve
parts within tolerance. Most commonly, these parameters have to do
with power settings to the laser, feed
of powder, amount of powder, speed
of laser/orifice in traverse movements,
and amount of inert atmosphere protecting the process.
While still in its infancy, the benefits of metallic additive manufacturing are beginning to be understood
and as its processes spread beyond
the defense, aerospace and medical
sectors into new industries, a new era
of modern machining is emerging. mt

Building additive parts
requires a building process
that differs greatly from
traditional subtractive
manufacturing.

Sven Thiesen is Chief Operating Officer
of OPTIS, a joint venture that brings
together the deep machining expertise,
analytic tools and process improvements
of TechSolve with the heritage and global
commercial reach of Castrol, to deliver
