Laser Sintering (SLS) is a rapid prototyping and manufacturing
process that sinters (fuses) a variety of nylon-based materials
for quick-turn models or for short-run production. Parts made
from SLS are much more robust than those made from SLA, and
because support structure is not required assemblies and very
complex large geometries shapes can be used with SLS. For
multi-parts needs, SLS performs well because the machine builds
in the X, Y and Z axes, allowing for optimal build sizes.
Completed parts can easily be sanded smooth, painted, dyed,
plated and assembled, and offer significant weight savings
for weight-sensitive applications. |

Direct Metal Laser Sintering (DMLS) is the leading "additive"
process for creating complex metal parts that are often difficult
to machine or investment cast. The process involves a 200
watt Yb laser sintering or melting the powder material layer
upon layer until the part is created. Leadtimes are typically
2 - 3 days for small parts, and 5 – 8 days for larger parts.
The build material is pure metal ground down from bar stock
to a 20 micron size. Parts produced from this process are
high in detail and typically hold very tight tolerances. After
parts are produced, they are fully dense and as strong as
wrought or cast parts. Post machining, EDM, polishing and
other services can easily be done to DMLS parts. |

Stereolithography
is the first and the oldest layer-manufacturing process and
continues to produce conceptual models in a few hours or days.
Parts made from SLA can quickly be used to make cavities in
silicone molds, serve as patterns for investment or plaster
castings, and can also be easily painted for form and fit
studies. SLA materials have evolved and now we offer high-temp
and composite-based resins. For high-resolution needs, we
also offer modified SLA machines and lasers that can build
as thin as .002” layer thicknesses, producing overall tolerances
of .010”.

Using
the latest machinery and software, Lasersintering.com powered
by Additive Manufacturing LLC offers 3rd, 4th and even 5th
axis machining services, and can quickly produce parts,
models, fixtures, and tools for short-run and high-volume
quantities. In addition to fast leadtimes, we also offer
very competitive pricing, and can hold tolerances that are
typically at or less then +/-.005”. Our master machinists
have years of experience and are skilled at producing exceptional
parts that are thoroughly inspected. We also use our CNC
equipment to support post process requirements for all services,
including DMLS.
We can machine every commercially available
plastic and metal material.

The
Polyjet process Lasersintering.com powered by Additive Manufacturing
LLC offers is perfect for reproducing prototype models while
achieving details as fine as 0.0006”. Polyjet parts do not
require support structure, and is best suited for accurate
and detailed applications. Multiple shore A and D materials
are available in addition to clear materials and two-tone
(overmolded) capabilities. Polyjet also offers a variety
of colors that can be used simultaneously. The build tray
size for our largest machine is 19” x 15.5” x 8”. |

Fused
Deposition Modeling (FDM) is a rapid prototyping service
that extrudes production-grade thermoplastic material to
produce prototypes and additive manufacturing applications.
Completed parts are robust, extremely high in accuracy,
and have crisp details. The materials offered includes ABS
(multiple colors), PC-ABS, Polycarbonate, Ultem 9085, PC-ISO,
and Polyphenylsulfone. These materials are literally extruded
onto each layer and by layer to create a two-dimensional
cross sections of the model. This section solidifies, and
the platform descends. This Process is repeated until the
model is complete. Like SLA and DMLS, FDM parts also require
support structure, which is easily removed. We also offer
vapor honing for parts that require a smooth, glossy finish.

powered by Additive Manufacturing LLC also offers electron
beam melting (EBM), which is less known than DMLS yet it
creates large solid metal parts using pure alloys. The EBM
machine uses an electron beam gun to melt metal powder at
70 micron layer thickness, and builds solid details that
have homogeneous material structure. Our primary material
in usage is Ti-6AI-4V. The build chamber size is 9.8” x
9.8” x 10” and produces large, detailed parts that have
particularly high volume and tall Z height.
Post process machining, such as welding, brazing, machining
or even extrude honing, is often required if tolerances
tighter than 0.010” – 0.040” are required. As-built surface
quality is approximately 250 RMS but can be finished to
32 RMS.

Temperature Vulcanizing (RTV) is a short-run molding process
used to produce anywhere from 5 to 200+ parts from materials
that simulate injection-molded plastics. The process begins
with the creation of a high-resolution master pattern from
SLA, Polyjet, FDM or CNC, which is encapsulated in a high-quality
silicone mold. Upon removing the pattern from the mold, urethane,
epoxy or silicone-based materials are shot in to the mold
under semi-high pressure, producing parts that are bubble
and void of any imperfections on the surface. The process
is repeated for as many parts is needed. A large variety of
shore A and shore D materials are available in addition to
pigmented and clear materials and several shore A silicones.
All parts from Additive Manufacturing LLC are cast in color
and with texture. Post processes include insert installation,
EMI shielding, painting, plating and more. Filler can also
be added for additional strength and alternate material requirements.
Parts of all sizes can be made with our largest one-piece
mold capable of exceeding 7’ x 7’ x 5’.

EDM is ideal for creating one off or production-run volumes
of small, intricately detailed metal parts that are often
too small for DMLS. EDM is also excellent as a post process
for DMLS when small features are called out that are difficult
to produce as grown with DMLS or too small to post machine.
The process removes small areas of material by a rapidly
recurring current discharge between two electrodes separated
by a dielectric liquid and subject to an |
