PA 12 W (Polyamide 12 White)


PA 12 W is a Polyamide 12 (“Nylon 12”) and differs from our standard PA 12 (HP High Reusability PA 12) mainly in color. PA 12 W is white and can therefore be colored as desired.
The material is processed in the Multi Jet Fusion 3D printing process, is a rigid, high-quality and versatile plastic, which was developed for additive series production.


NOTE: The material is in the introductory phase (“beta”), therefore longer delivery times and increased general tolerance can currently still be expected compared to standard PA 12.

Material Properties


Mechanical Properties

  • Tensile strength: ~ 48 ± 5 MPa
  • Elongation at break: 13 ± 6
  • Modulus of elasticity: 1,500 ± 200 MPa
  • Density: ~0.9 – 1.0 g /cm³ (depending on geometry)

Polyamide 12 is a strong, very resilient and durable plastic. The material properties are largely isotropic (same mechanical key figures in all orientations).

Thermal Resistance

  • Heat deflection temperature (HDT) at 0.45 MPa: 175 °C
  • Heat deflection temperature (HDT) at 1.82 MPa: 95 °C

For permanent loads, 95 °C should not be exceeded. For short-term loads, up to max. 120 °C are possible, depending on the geometry. Especially with thin walls (< 2 mm) and/or simultaneous mechanical or dynamic stress, the load capacity is reduced.

Surface Properties

  • Roughness Ra bottom side: 5 ± 2 µm
  • Roughness Ra top side: 10 ± 2 µm
  • Roughness Ra slope (45°): 8 ± 2 µm

The raw material processed in the Multi Jet Fusion is a powder. This results in a slightly rough surface, similar to fine sandpaper. The stair-step effects (print lines) typical in 3D printing are visible at shallow angles (up to approx. 15°) and are quite fine, since the layer thickness is only 80 micron.

Color
Off-White, with a slight bluish tint. The color remains stable even under UV exposure and does not yellow (Delta E deviation below 2.5 / 1,000 hours).

Accuracy


The general tolerance during the introduction phase (“beta”) is 0.5 mm for up to 100 mm outside dimension, above its 0.5 %. In the case of large-area, flat geometries, warpage may occur.

Design Guidelines

Minimum Wall thickness

Minimum Wall Thicknesses
The minimum wall thickness should not be less than 1 mm. For longer objects/surfaces or for objects exposed to mechanical loads, you should increase the wall thickness.

Cavities

Cavities
Hollowed objects can be printed, but openings (min. 10 mm diameter) must be inserted so that excess material can be removed. For larger cavities, you should plan for several openings. The source material is compacted during the printing process, so excess material is very difficult to remove.

Spacing

Spacing
Keep a distance of min. 0.5 mm for grooves or walls that are close to each other. Individual objects (“shells”) must always be uploaded as a separate file unless they are firmly connected to each other.

Resolution

Resolution
Details down to a size of approx. 0.5 mm can be displayed.

Interlocked objects

Interlocked Objects
Interlocked objects can be printed. Please note the minimum distance between the objects of min. 0.5 mm. Also note that the corresponding areas are accessible in order to be able to remove excess material powder.

Size

Size
The object should not be larger than 370 x 274 x 380 mm.

Applications

The PA 12 W material can be used for rapid prototyping as well as is for additive series production of end-use parts. The material differs from our standard PA12 in color, the mechanical properties are comparable. PA 12 W is white and can be dyed into numerous colors.

PA 12 W is therefore particularly suitable for white & colored components in visible areas. Applications include, for example:

Cases
The high mechanical strength and the possibility of coloring the durable and robust material make it ideal for an application of housings and panels.

Orthoses
Depending on the required properties, polyamide 12 is used in addition to TPU. PA 12 W enables the production of colored orthoses.

Consumer Products
Colors often play a greater role in consumer products than in industrial components. Here, PA 12 W enables versatile possibilities for the production of white and colored products and product components.
