HP 3D PRINTED MATERIALS
PA 12 Black is a high tensile strength nylon. Parts exhibit a high quality surface finishes and slightly more isotropic mechanical properties when compared to SLS
Polypropylene is a versatile material ideal for a wide range of automotive, consumer, industrial, and medical applications. This material is more flexible than PA12 or PA11.
This thermoplastic polyurethane (TPU) combines rubber-like elasticity and elongation with good abrasion and impact resistance. Ideal for automotive components due to its high chemical resistance to oil and grease.
HP PA12 MATERIAL SPECS
MJF Nylon 12 has been engineered especially for HP Multi Jet Fusion technology and has been designed for production of functional parts across a variety of industries. MJF Nylon 12 provides the best balance between performance and price and has been engineered to produce final parts and functional prototypes with fine detail and dimensional accuracy.
Properties and accuracy
MJF 3D printed parts have a higher accuracy than SLS – official stats from HP are +-0.2mm per 100mm with a lower limit of +-0.2mm, but being a heat process, different models are affected in different ways (e.g. slight distortion of long thin parts).
Colour, Texture & Flex
Multi Jet Fusion PA12 parts are Raw Grey (non uniform) once printed. A uniform and good looking finish can be achieved by dyeing in black. MJF 3D printed parts have a slightily grainy and powdery surface finish (smoother than SLS). The surface is uniform and ideal also for finished parts. MJF PA12 parts do have a degree of flexibility: they can be used for making snap fits as well as be functionally rigid when thicker than 5mm.
