SLS Material Options

PA12 (White)
PA12 (Black)
PA12 GF
PP GF
TPU

PA12 (White)

Material Reference: FS3300PA (SLS)
Appearance: White, Off-white

White Nylon PA12 is the industry standard for SLS. It offers high wear resistance, excellent thermal stability, and outstanding mechanical strength.

Key Features
Tensile strength: 46 MPa
Impact strength: 4.9 kj/m² notched
Elongation at break: 36%

PA12 (Black)

Material Reference: FS3201PA-F (SLS)
Appearance: Black

SLS Black Nylon 12 offers high wear resistance, excellent thermal stability, and strong mechanical performance with improved impact resistance compared to standard PA12.

Key Features
Tensile strength: 42 MPa
Impact strength: 10 kj/m² notched
Elongation at break: 30%

PA12 GF

Material Reference: FS3300GF (SLS)
Appearance: Off-white to brown, grainy/rough

Glass-Filled Nylon (PA12 GF) is a high stiffness industrial-grade engineering plastic that can be a good alternative to metal. It’s ideal for demanding conditions where toughness, temperature performance or wear resistance is key.

Key Features
Heat resistance: ~100°C
Stiffness: 3500–7800 MPa
Flexural strength: 68 MPa

PP GF

Material Reference: 3200P (SLS)
Appearance: Off-white, beige

Glass Filled Polypropylene (PP GF) is a semi-rigid material that offers good toughness, fatigue resistance, and elongation at break. It’s suitable for snap-fits, housings and living hinges.

Key Features
Tensile modulus: 3500–7800 MPa
Heat resistance: up to 162°C
Elongation at break: 40%

TPU

Material Reference: SLS TPU
Appearance: Off-white/beige, black

With SLS, you can 3D print TPU or rubber-like parts. It is very elastic, flexible, and smooth to the touch, but at the same time, extremely durable and strong, widely used in the automotive, medical and consumer goods industries.

Key Features
Elongation at break: 500–520%
Shore hardness range: ~85A–98A
Abrasion resistance: 28–31 mm³

SLA Surface Finishing Options

SLA Surface Finishing Options

Deburr / As-Printed

Deburr / As-Printed

Deburring is our standard finish. Parts cleaned of loose powder and sharp edges.

PA Black Dye

PA Black Dye

Parts cleaned of loose powder and sharp edges. Appears more grey to dark grey rather than deep black.

PA Colour Dye

PA Colour Dye

Fastest and most cost-effective way to colour white SLS parts to different Pantone/RAL colours.

PA Black (Deburr)

PA Black (Deburr)

Parts cleaned of loose powder and sharp edges. Appears more grey to dark grey rather than deep black.

PA Black (Smooth)

PA Black (Smooth)

Smooth finish may result in a lighter grey appearance while improving surface uniformity.

PA12 GF Deburr

PA12 GF Deburr

Parts cleaned of loose powder and sharp edges. Notably rougher and more grainy than unfilled PA12.

PA12 GF Black Dye

PA12 GF Black Dye

Glass-filled additives makes achieving deep black colour difficult. Expect colour variations.

PA12 GF Smooth

PA12 GF Smooth

Smoothing reduces surface roughness. Residual texture may remain due to glass-filled additive.

TPU Polishing

TPU Polishing

TPU parts can be chemical polished to produce a smoother, more glossy surface finish.

TPU White (Deburr)

TPU White (Deburr)

Parts cleaned of loose powder. Leaves a natural white and slightly granular matte surface.

TPU Black (Deburr)

TPU Black (Deburr)

Parts cleaned of loose powder. Leaves a natural white and slightly granular matte surface.

PA White (Vapour Smoothed)

PA White (Vapour Smoothed)

Smooths and seals the surface and enhances elongation at break and fatigue resistance. Ideal for parts with intricate details.

PA Black (Sand Smoothed)

PA Black (Sand Smoothed)

Smooths the surface and may result in a lighter grey appearance while improving surface uniformity. Some graininess may remain.

PA Black (Vapour Smoothed)

PA Black (Vapour Smoothed)

Smooths and seals the surface and enhances elongation at break and fatigue resistance. Can result in a high gloss finish.

Advantage and Drawbacks of Accuro Rapid SLS printing

Advantages of SLS

Advantages of SLS

No Support Structures: Unsintered powder naturally supports complex geometries.

Wide Material Range: Nylon, glass-filled nylon, TPU, PEEK and other engineering powders available.

Good Mechanical Performance: High strength & toughness for functional end-use parts.

Limitations of SLS

Limitations of SLS

Rough Surface:Grainy as-printed surface, blasting/polishing required for smoothness.

Limited Fine Features:Poorer micro-detail resolution compared to SLA.

Powder Cleanup Required:Residual loose powder needs removal during post-processing.

Design Guidelines for SLS

To achieve high dimensional accuracy, reduce warping and successful prints, it is important that you design for the process. See the SLS design guidelines below.
