3D printing, how to choose the right material, case study

Selective Laser Sintering is a process that uses high-powered CO2 lasers to selectively melt and fuse powdered thermoplastics.
This process is ideal if you are looking to produce tough, functional parts, with the possibility to achieve excellent surface finish and fine detailing.
How to choose exactly the right material combination for  designed parts?

Tough Black Nylon 11

Tough, impact and fatigue-resistant black Nylon 11 for prototypes and end-use parts
requiring molded-part performance in harsh environments.

Benefits

Complex end-use parts can be economically manufactured without the expense of tooling

Parts have toughness required to replace injection molded ABS and polypropylene

Functional parts can be tested in real life environments such as crash tests or other
stress simulations

No painting required for a deep black color that doesn’t fade or chip

Application

Production parts
Snap fits / living hinges
Automotive design
Aerospace parts and ducting
Jigs / fixtures / tools
Connectors

Tough Natural Colored Nylon 11

Tough and durable polypropylene-like thermoplastic for prototypes and end-use parts
requiring molded-part performance.

Benefits

Flexible / durable
High elongation
High impact strength
Ideal for snap-fit and living hinges –
plastic parts that are flexible enough to fold over 180° and bounce back to their original shape
Parts have toughness required to replace injection molded ABS and polypropylene
Functional parts can be tested in real life environments such as crash tests or other stress simulations

APPLICATIONS

Tough and durable prototypes
Low to mid volume direct
manufacturing of end-use parts
Complex, thin-walled ducts
Aircraft and motorsports parts
Enclosures and housings
Parts with snap-fits and living hinges

Biocompatible Nylon 12

Strong, tough biocompatible material that stands up to the rigours of long-term real
world use, replacing traditionally injection molded articles.

APPLICATIONS

Production parts
Snap fits
Automotive design
Aerospace parts and ducting
Medical / food applications
Jigs / fixtures / tools
Covers / housings / enclosures

Benefits

Suitable for general prototyping and
end-use manufacturing
Compliant with FDA CFR 21 11 and the
Plastic Directive of the European Union (EU),
No 10/2011and its amendments
Suitable for medical parts that require USP
Class VI and ISO 10993 compliance or must be sterilized
Exceptional recycling rate reduces waste
and decreases production costs

Flame Retardant Nylon 12

Ideally suited for end-use parts in aerospace, transportation and consumer goods where
excellent surface finish, reliable fire retardancy and reduced smoke and toxicity are required.

Application

Cabin interiors for aerospace
& transportation
Fire retardant production parts
Consumer goods needing modest
fire retardancy

BENEFITS

FAR 25.853 certified for aerospace use.
Passes AITM smoke density and toxicity
requirements
Excellent flame retardancy at 12-and
60-second exposures. UL 94-V2 Compliant
Excellent surface quality for end-use parts

Aluminum-filled Nylon 12

Excellent surface finish and high stiffness with a metallic aesthetic delivered directly from the printer. Easily machined and polished to add press fits, tappings and other post-print modifications.

Production parts
Automotive interior styling parts
Aerospace components
Jigs / fixtures
Rigid enclosures / cases

Benefits

Aluminum-filled Nylon 12 with a metallic
appearance
Excels in load-bearing applications at high
temperatures
Excellent surface finish for end-use parts
Improved recyclability for an aluminumfilled
powder leading to a lower cost per part
