The established PA 12 solution: consistent material quality and high process reliability – ideal for series production and long-running projects.
More information

APPLICATION
Universal option for (almost) all components in visible and non-visible areas.

Our most economical option: Essential offers a robust balance between cost and quality – the ideal choice for functional prototypes and cost-efficient small series.
More information

APPLICATION
Rather compact components with a focus on cost-efficiency.

Our best surface finish: Thanks to an especially fine raw material, a smooth and homogeneous feel is achieved – ideal for visible components in housings, devices, or control elements where appearance matters.
More information

APPLICATION
Visible parts, including bulky ones, such as housings.

Our most powerful option: Optimized material and printing parameters ensure maximum durability and dimensional stability – recommended for stressed functional parts.
More information

APPLICATION
Parts with increased requirements for mechanical load.

Our widest color range: “PA 12 W” has a white base color and can be dyed in various colors. This makes it the ideal material for visible parts with color requirements or components in industrial signal colors.

APPLICATION
Visible components with color requirements.

Our flame-retardant option: “PA 12 FR” is a flame-retardant version of PA 12 and meets the UL 94 V0 classification from 2.5 mm wall thickness. It is suitable for applications with increased safety requirements, particularly in electrical and transportation environments.

Housings
PA 12 provides impact resistance as well as thermal & chemical resistance and, after finishing, delivers excellent appearance & feel.
Recommended variants: PA 12 | Smooth, White or Classic with coloring and Shot Peening.

Mechanical Parts
PA 12 is flexible when thin-walled, rigid when thick-walled, abrasion-resistant – ideal for gears, connectors, propellers, and more.
Recommended variants: PA 12 | Performance or Classic, optionally combined with chemical smoothing for thin, dynamically loaded, or friction-intensive parts.

Structural Components
PA 12 enables freely designable, resource-efficient mounts – from circuit board to motor brackets – highly optimized with minimal material usage.
Recommended variants: PA 12 | Essential

Tools & Fixtures
The production method enables fast manufacturing of complex fixtures. The material is, among others, oil-resistant and can withstand both thermal and mechanical stress.
Recommended variants: PA 12 | Performance (for dynamic load or thin walls), Essential or Classic.

Gas-Conducting Systems
PA 12 allows the production of complex internal channels and integrated connectors in a single print job – without assembly. For absolutely leak-proof channels, we work with you to ensure the design-dependent minimum channel diameter.
Recommended variants: PA 12 | Classic or Essential combined with Chemical Smoothing.

Orthoses
PA 12 enables patient-specific shapes, is skin-friendly and extremely durable – perfect for long-lasting orthoses. For flexible areas, we additionally recommend elastic TPU.
Recommended variants: PA 12 | Classic, Smooth, White or Performance, depending on the application.

HP Multi Jet Fusion PA 12 is characterized by exceptionally high resistance to non-polar media. Engine, transmission and hydraulic oils, diesel as well as common coolants and windshield washer fluids hardly affect the material even under continuous exposure – dimensional stability and mechanical properties remain almost unchanged.

With strongly polar liquids, e.g. brake fluid (DOT 4), PA 12 absorbs a small amount of mass and loses strength. For critical sealing areas, we recommend thin barrier coatings or constructive safety margins.

PA 12 | White is also sterilization-resistant: steam, EtO, gamma and e-beam cycles cause only minimal changes (< 10% strength loss, ΔE < 2). This makes PA 12 ideal for reprocessable medical devices and functional parts in the food & life science sector.

Polyamide 12 therefore offers a wide range of applications – from heavily loaded automotive components to fluid handling systems to medical devices.

UV Resistance
Good: The base polyamide withstands short-term radiation, but ages visibly under permanent outdoor exposure (discoloration, embrittlement).

Practical Notes
For permanent outdoor use, provide black coloring or clear coat/PU coating.

PA 12 | White


UV Resistance
Very Good: The white powder contains a light-stable additive package that protects the material against yellowing for a long time.

Practical Notes
With long-term exposure, yellowing may eventually occur, which can be reduced by coloring or coating.

HP HR PA 12 S enabled by Arkema
PA 12 | Smooth


UV Resistance
Very Good: PA 12 S is based on a specially modified PA 12 system with UV additive.


Practical Notes
The material is ideal for continuous outdoor use. Here too, at least black coloring is recommended.

Minimum Wall Thicknesses

For free-standing walls or extrusions as well as for larger surfaces, the wall thickness should be increased accordingly.

Maximum Wall Thicknesses

From approx. 6 mm wall thickness, we insert a lattice structure into models before printing. For some variants (Classic, Performance, White) you can opt out of this. More info on lattice structures can be found here.

Maximum Size

The maximum size for all variants is 370 x 274 x 380 mm.

Minimum Size

The detail resolution of very small parts is limited. We recommend that at least one dimension of the part exceeds 10 mm.

Maintain a minimum clearance of 0.5 mm between two walls (applies to all variants).

Individual objects (“shells”) must always be uploaded as separate files if they are not firmly connected.

Details down to a size of approx. 0.5 mm (guideline value) can be displayed.
Variants with better surface quality, especially PA 12 | Smooth, can also be slightly smaller, whereas PA 12 | Essential has reduced resolution.

Interlocking objects can be printed in all variants.
Please note the minimum clearance between objects of 0.5 mm and ensure that the corresponding areas are accessible to remove excess material powder.

Hollow objects can be printed in all variants, but openings (min. 10 mm diameter) must be added so that excess material can be removed.
For larger cavities, you should plan several openings. The raw material is highly compacted during the printing process, so removing excess material is very difficult.
