DMLS Advantages and Disadvantages - Aurum3d

DMLS Advantages and Disadvantages
While creating a part or prototype, you have the
option to choose from several additive
manufacturing technologies. Each additive
manufacturing technique produces the part or
prototype using fusing specific materials or
filaments. Direct metal laser sintering (DMLS) is
a widely used 3D printing technology that
produces fully-functional production parts and
prototypes using metal materials.

Like other 3D printing technologies, DMLS prints
solid three-dimensional objects layer by layer
based on digital 3D models. But DMLS, unlike
other 3D printing technologies, creates
opportunities for engineers to produce parts
using a variety of metal alloys. The DMLS
printers spread thin layers of metal powder on
the build platform. The metal powder is sintered
selectively using a laser.
The laser makes DMLS effective in producing solid
items without melting the metal powder. The
sintering feature makes DMLS different from
widely used metal additive manufacturing
technologies like selective laser melting. At
present, enterprises use DMLS for both rapid
prototyping as well as mass-production of metal
parts. But you must remember that DMLS, like
other metal additive manufacturing technologies,
has its pros and cons. You can print superior
parts or prototypes only by understanding major
DMLS advantages and disadvantages. The
understanding will help you to boost the metal 3D
printing process by overcoming some of the
important shortcomings of DMLS.

Here are the major Advantages of DMLS 3D Printing.
Wide Range of Metals
DMLS facilitates metal additive manufacturing by
supporting a wide range of metals aluminum,
titanium, steel, stainless steel, cobalt chrome,
nickel alloys, and precious metals. Hence,
engineers have the option to choose from both
pure metals and metal alloys according to the
requirements of the 3D printer. Also, many
companies have been launching new metal filaments
to leverage the growing adoption of DMLS
technology.
Direct Metal Printing
In addition to supporting a wide range of metal
alloys, DMLS prints the metal parts or prototypes
directly. Direct metal printing helps engineers
to keep the properties of the metal alloy intact.
Many engineers further leverage the feature to
produce innovative and superior parts by
combining multiple metal powders.
Production of Strong Functional Parts
As mentioned earlier, enterprises these days use
DMLS technology to produce both fully-functional
parts and prototypes. The metal alloys make DMLS
effective in producing functional parts that are
both strong and durable. Also, engineers can
create metal parts without melting the metal
powder. Hence, the mechanical properties of the
metal remain intact after the part is produced.

Mass Customization
While using DMLS technology, engineers can
produce parts without using tools or fixtures.
The absence of tooling and fixturing makes it
easier for them to customize and fine-tune the
metal parts during mass production. They can
simply make relevant changes to the design and
produce many variants of the part on a mass scale.
Material Reusability
Like SLS 3D printing technology, DMLS enables
engineers to reuse the unsintered metal powder
after the printing process. The material
reusability makes the technology effective in
producing parts and prototypes without increasing
material wastage and escalating overall material
costs.

Here are the major Disadvantages of 3D Printing
High Printing Costs
The overall cost of a 3D project varies according
to both technology and filament. DMLS is one of
the relatively expensive additive manufacturing
technologies. Enterprises have to incur both
upfront and recurring expenses to combine the
machine and materials. That is why DMLS is often
described as an industrial additive manufacturing
technology. It is widely mainly by enterprises to
produce metal parts and prototypes.
Porous Parts
DMLS produces more porous parts than other metal
additive manufacturing technologies. The
engineers also have the option to control the
porosity during the DMLS printing process. But
they lack the option to eliminate the porosity
during the post-processing stage.
Small Build Volume
While planning 3D printing projects, engineers
always choose and recommend the appropriate
technology based on the build volume. DMLS is one
of the metal additive technologies that have
relatively small build volumes. The smaller the
build volume makes the technology suitable for
small parts. Enterprises often look for DMLS
alternatives while producing large parts.
