In black, it is also available in a smooth and slightly glossy finish. MJF Plastic PA12 is an ideal choice for a wide range of applications from industrial parts to durable end-use goods. Its strength, durability and stiffness make it great for functional parts, such RC car parts and mounts. It is also popular for home decor, eyewear and games. MJF Plastic PA12 is printed using HP’s Multi Jet Fusion technology and supports very complex geometries and thin features. More information about this printing technology can be found [Here](/content/3d-print-material-technology/hp-mjf/index.html) ### Color & Finishes Gray A shade of gray that can vary in lightness Black **Natural** This finish has a matte finish and slightly grainy feel. **Smooth** This finish has a smooth surface and slight shine, created using a physio-chemical process to vapor smooth the surface. ### Technology - Multi Jet Fusion [MJF] ### Technical Documents [HP MJF PA 12 Data sheet](/content/wp-content/uploads/2021/01/HP-MJF-PA-12-Data-sheet.pdf) [Nylon PA12 - MJF - Safety Data Sheet (SDS)](/content/wp-content/uploads/2021/06/Nylon-12-MJF-Safety-Data-Sheet-SDS.pdf) [Nylon PA12 - MJF - PAHs (Polycyclic Aromatic Hydrocarbons) CERTIFICATE](/content/wp-content/uploads/2021/06/Nylon-12-MJF-PAHs-Polycyclic-Aromatic-Hydrocarbons-CERTIFICATE.pdf) [Nylon PA12 - MJF - Biocompatibility CERTIFICATE](/content/wp-content/uploads/2021/06/Nylon-12-MJF-Biocompatibility-CERTIFICATE.pdf) [Nylon PA12 - MJF - UL 94 and UL 746A Certification Technical Note](/content/wp-content/uploads/2021/06/Nylon-12-MJF-UL-94-and-UL-746A-Certification-Technical-Note.pdf) [Nylon PA12 - MJF - Summary of Regulatory Compliance and Environmental Attributes](/content/wp-content/uploads/2021/06/Nylon-12-MJF-Summary-of-Regulatory-Compliance-and-Environmental-Attributes.pdf) [Nylon PA12 - MJF - Statement of Composition for Toy Applications CERTIFICATE](/content/wp-content/uploads/2021/06/Nylon-12-MJF-Statement-of-Composition-for-Toy-Applications-CERTIFICATE.pdf) ### Material Properties - **Tensile modulus (ASTM D638)**: 1700 MPa (XY), 1900 MPa (Z) - **Tensile strength (ASTM D638)**: 50 MPa - **Elongation at break (ASTM D638)**: 17% (XY), 9% (Z) - **Flexural modulus (23°C)(ASTM D790)**: 1730 MPa ### Description Material Highlights High strength & durability, good impact resistance, professional finish, thin features & interlocking parts - **Flammability degree (UL 94)**: HB rating (<75mm/min for thickness of 0.75mm) - **Electrical conductivity (UL 746A)**: Dielectric strength value 2.8kV/mm, volume resistivity value 10^14 ohm-cm ## Design Guidelines ### Bounding Box **Maximum Bounding Box** 284 x 380 x 380 mm (Gray Natural and Black Smooth) 210 x 210 x 360 mm (Black Natural) Note: Parts covering the exact maximum bounding box dimensions might not be printable due to printer limitations. **Minimum Bounding Box** 4 x 4 x 1 mm or X + Y + Z > 9 mm (Gray and Black Natural) 15 x 10 x 5 mm (Smooth) The bounding box is a 3D imaginary outline of a box that encloses the smallest area occupied by your model. Your model must be within the minimum and maximum bounding box sizes. If the size of the model is close to the maximum bounding box, then the printing orientation will be restricted. ### Walls **Supported Walls** 0.4 mm (Natural) 1.5 mm (Smooth) **Unsupported Walls** 0.5 mm (Natural) 1.5 mm (Smooth) ### Wires **Supported Wires** 0.8 mm (Natural) 1.5 mm (Smooth) **Unsupported Wires** 0.9 mm (Natural) 1.5 mm (Smooth) ### Details **Embossed Details** 0.2 mm high & wide (Natural) 0.3 mm high & 0.5 mm wide (Smooth) **Engraved Details** 0.2 mm deep & wide (Natural) 0.3 mm deep & 0.4 mm wide (Smooth) ### Escape Holes **Single Escape Hole Diameter** 4.0 mm (Natural & Smooth) **Multiple Escape Hole Diameter** 2.0 mm (Natural & Smooth) ### Clearance **Minimum** 0.6 mm (Natural) 0.7 mm (Smooth) ### Sprues **2 mm thick, attached in at least 2 places per part** ### Interlocking & Enclosed Parts **Interlocking** Supported (Natural) **Not Supported** (Smooth) **Enclosed** Supported (Natural) **Not Supported** (Smooth) ### Parts in File 1 ### Accuracy Natural: ± 0.2 mm ± 0.5% of the length Smooth: ± 0.4% (with a lower limit of ±0.2 mm) ## Related Materials Also known as HP PA12 Glass Beads, PA12 GB, Glass-filled PA12, PA12 GF, Nylon 12 GB **Application:** Tooling, Robotics, Drones, Fixtures, Medical Braces, Housings, Cases Thermoplastic Polyurethane [TPU] , Ultrasint™ TPU01
