FINELINE ADDITIVE MANUFA CTURING

FINELINE ADDITIVE MANUFACTURING
Fineline Additive Manufacturing specializes in the rapid
prototyping of three-dimensional objects. Within Fineline,
we offer three high-tech processes: stereolithography
(SL), selective laser sintering (SLS) and direct metal
laser sintering (DMLS). Whether small parts with precise
geometries or large, highly detailed patterns are needed,
our additive processes provide product developers with
another quick-turn option during prototyping.
Each additive process has its own benefits. SL has the
widest selection of materials, best feature resolution and
smoothest surface finish. SLS offers a large build volume,
can produce parts with highly complex geometries and
creates durable prototypes made from tough nylon
materials. For production-quality metal parts, Fineline
uses DMLS to build functional metal prototypes with
the potential to transition into metal injection molding if
increased production is needed.
DESIGN CONSIDERATIONS
Size. With our additive processes, we’re able to deliver
prototypes ranging from very small parts that meet extreme
tolerance demands to large parts with precise patterns.
Maximum build sizes:
• 29 in. by 25 in. by 21 in. (SL)
• 18 in. by 18 in. by 22 in. (SLS)
• 9.8 in. by 9.8 in. by 11 in. (DMLS)
Resolution. Fineline excels in high-quality precision parts.
Depending on which additive process and resolution is chosen,
layer thickness and minimum feature size will vary.
Stereolithography
• Normal Resolution: Layer thickness of 0.004 in. with
minimum feature size of 0.010 in.
• High Resolution: Layer thickness of 0.002 in. with
minimum feature size of 0.004 in.
• Micro Resolution: Layer thickness of 0.001 in. with
minimum feature size of 0.002 in.
Selective Laser Sintering
• Normal Resolution: Layer thickness of 0.004 in. with minimum
feature size of 0.022 in.
Direct Metal Laser Sintering
• Normal Resolution: Layer thickness of 0.0008 in. (20 microns) with minimum feature size of 0.015 in.
• High Resolution: Layer thickness of 0.0012 in. (30 microns)
with minimum feature size of 0.006 in.

Materials. We offer various material options within our
additive processes that are constantly updated to meet prototyping
and master fabrication needs. Our materials provide many different
characteristics: resolution, clarity, stiffness and feel, durability,
impact resistance, temperature tolerance, and water resistance.
Materials include:
Stereolithography
•ABS-like
•Polycarbonate-like
•Polypropylene-like
• SLArmor (nickel-plated)
Selective Laser Sintering
• Nylon (four types in various
levels of stiffness and ductility)
Direct Metal Laser Sintering
•Aluminum
•Cobalt Chrome
•Inconel
"Any time I need the
best quality parts with
the proper fit, I use
Fineline. Nobody else
can touch their work
when it comes to making
parts such as ours."

•Stainless Steel
•Titanium
Tolerances. Typical tolerances on well-designed additive parts are:
• +/- 0.002 in. to +/- 0.004 in. plus 0.001 in./in. (SL)
• +/- 0.005 in. plus 0.001 in./in. (SLS)
• +/- 0.003 in. plus 0.001 in./in. (DMLS)
Surface finishes. There are five different finishes with our
additive manufacturing service. Fineline can also color- and
texture-match paints; chrome plate and rubberized soft-touch
coat; and apply graphics and decals. A conversation with an
additive specialist at Fineline is required for special finishes.
