DMLS Advantages and Disadvantages - Aurum3d
                     DMLS  Advantages  and  Diisadvantages
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.

Mettalls
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 
leivreratg e thte lg rowing adoption of DMLS technology.Direct Metal 
Prriinttiing
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.

Parrtts
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  
Custtomiizattiion
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 
Msacttaelrreii.all  Reusabiilliitty
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.

Hiigh  Prriinttiing  Costts
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.
Porrous  Parrtts
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.
Smallll  Buiilld  Vollume
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.
