Twin Sourcing vs Twin Manufacturing: How offer chain and manufacturing can much better have an understanding of AM in generation.


Traditionally, the alternative of section generation system has been
grounded in demands. Mating geometries, energy and chemical resistance wants,
and envisioned amount of “cycles” have dictated decisions in both product and
production strategy.

There are now several processes that can generate components that
fulfill the same engineering necessities. Additive procedures are normally massively
much more price tag-productive than classic manufacturing at modest (and numerous periods
reasonable) volumes. This opens up options for engineering and offer chain to
collaborate on production effectiveness.

At initial, “Dual Manufacturing” could audio like a common
provide chain expression, “Dual Sourcing,” but there are critical distinctions:

Twin Sourcing is
the procedure of using two or extra suppliers for a presented element, uncooked substance,
or services. Typically dual sourcing is utilised to minimize risk, lower value, diversify
geographically, or for other strategic motives.

Dual Manufacturing is
the system of making use of two generation processes in parallel to produce equal
elements. The creation procedures will enhance every other to give some
benefit (e.g. productive manufacturing in excess of a vast vary of volumes, geographic
range, or shortened lead moments). Frequently, just one process will be a regular
manufacturing process (injection molding, urgent, casting, and many others.) which is
successful at volume, at the expenditure of overall flexibility and mounted startup charge. The
next approach commonly tends to make use of digital production, like additive
production or CNC machining.

The adaptability of getting two procedures has a tradeoff. You
obtain enhanced manufacturing adaptability, but typically incur some expense of engineering
work to style for two production solutions. Odds are reduced that a style will
be optimal for two distinct manufacturing procedures (i.e. injection molding and
additive), so two component styles (equal pieces) will generally be needed.

As an illustration, a nylon gear (pictured) might be intended with
an interior cutout to make it possible for for aspect cooling when injection-molded. That very same
equipment may be developed as a solid gear working with additive to enhance for speed of
printing and post-processing.

Twin manufacturing can make sense when some element of
manufacturing improvements to make a single type of producing beneficial than a further.
Some illustrations:

  • Lead moments grow to be vital (e.g. for a
    output launch)
  • Volumes of generation operates change widely (simply because
    of seasonality, sudden need, or aftermarket requirements)
  • Economics of manufacturing (labor expenses, import
    obligations, and many others.) vary throughout distinctive marketplaces.

In the circumstance of additive, dual manufacturing might make sense
when you need output at an satisfactory total price tag for every portion at the two substantial
volumes (for generation operates) and reduced volumes (for aftermarket desires).

Gleaning the economic rewards of twin production may perhaps
audio overwhelming, but it arrives down to understanding the price tag drivers of your
procedures one thing engineers and supply chain experts will come across
acquainted. As an illustration, let us appear at injection molding and fastened deposition
modeling (FDM) 3D printing certification.

In injection molding, preset expenses of creation incorporate
tooling, line set up, and creating/verifying initial articles or blog posts. Individuals costs ought to
be amortized throughout all the parts in your manufacturing operate. In contrast,
production utilizing FDM 3D printing certification incurs none of these mounted prices and generates
areas with really very little guide time, but generally comes with greater product
charges. In the case of extensive, predictable
output operates, injection molding will be the appropriate creation system.
Having said that, if a short run is desired, supplemental production capacity is required
temporarialy, or a section stocks out unexpectedly in large demand, 3D printing certification sometimes
will be the correct way to go. Only by acquiring equally procedures validated can your
production operation realize the pros of equally procedures.

Additive production certification is not
generally the answer to each issue, but wherever the economics and engineering
do the job, we’ve been equipped to help providers reach extraordinary results:

  • 50% reductions in
    component cost for creation line spare areas
  • Reduction of lead
    moments from 6 months to 2 times for key repair areas
  • Lower volume
    production enablement that helps make full product strains feasable

It is obvious to me that additive has large untapped
potential as a producing tool. On a own stage, that’s what is remarkable
to me about working with Stratasys Consulting, where by we’re clarifying these
issues and partnering with clients to help them make informed selections in
their offer chains.
