PA 12 W (Polyamide 12 White)

Mechanical Properties

• Tensile Strength: ~ 48 ± 5 MPa
• Elongation at Break: 13 ± 6 %
• E-Modulus: 1,500 ± 200 MPa
• Density: ~0.9 – 1.0 g /cm³ (geometry-dependent)

  Polyamide 12 is a solid, highly resilient, and durable plastic. The material properties are largely isotropic (similar mechanical characteristics 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 continuous loads, 95 °C should not be exceeded. For short-term loads, up to a maximum of 120 °C is possible depending on the geometry. Especially with thin wall thicknesses (< 2 mm) and/or simultaneous mechanical or dynamic stress, the load-bearing capacity is reduced.

Surface Properties

• Roughness Ra Bottom: 5 ± 2 µm
• Roughness Ra Top: 10 ± 2 µm
• Roughness Ra Slope (45°): 8 ± 2 µm

  The raw material used in Multi Jet Fusion is in powder form. This results in a slightly rough surface, similar to fine sandpaper. The typical 3D printing layer lines (print lines) are visible with shallow angles (up to about 15°) and are relatively fine due to the layer thickness of only 80 µm.

Colors
Off-white, slightly bluish color cast. The color is stable even under UV exposure and does not yellow (Delta E deviation below 2.5 / 1,000 hrs).

The general tolerance is 0.3 mm up to an outer dimension of 100 mm, and 0.3 % above this. In the case of large, flat geometries, distortion may also occur.

PA 12 W can be dyed. The Deep Dye Coloring process developed by Dyemansion is used for this purpose. The coloring is UV stable and replicable.

Standard colors
Dyeing in these colors is performed on a regular basis. They are listed in the Online 3D Printing Service as separate colors under Polyamide 12 W (white).

Special colors
These colors are used only upon customer request, thus the minimum turnover is higher than for standard colors. The process is identical. In our 3D printing price calculation, you can select this option under Polyamide 12 W (white) -> Color “White” -> “Other Services” -> “Special Colors” -> “Colorize with Special Color”. After selecting this option, you can choose the corresponding spot color in a drop-down field.

Vapor Smoothing (Chemical Smoothing)
Chemical surface treatment that produces a non-porous surface with reduced roughness. Major applications are liquid or gas carrying components, components where easy cleaning is required (medical, clean room) or as a basis for subsequent coating processes (reduction ‘outgassing’, reduction porosity, smoothing).

Notes on ordering
Delivery time: + 5 working days Price: depending on number of pieces and size, typical unit costs of approx. EUR 7 – EUR 10; plus VAT.

Minimum Wall Thickness
The minimum wall thickness should not be less than 1 mm. For longer objects/surfaces or objects exposed to mechanical stresses, it is advisable to increase the wall thickness.

Distances
Maintain a minimum distance of 0.5 mm for grooves or closely spaced walls. Individual objects (“shells”) must be uploaded as separate files unless they are firmly connected.

Resolution
Details as small as approximately 0.5 mm can be represented.

Size
The object should not exceed 370 x 274 x 380 mm in size.

The material PA 12 W can be used for both rapid prototyping and additive series production. The material differs from our standard PA 12 in color, but the mechanical properties are comparable. PA 12 W is white and can be colored in numerous colors.

Therefore, PA 12 W is particularly suitable for white and colored components in the visible area. The applications include, for example:
