Hp 3D Printer Material PA12
HP 3D Printer Material PA12 is a high resolution PA12 printed on the new HP Jet Fusion 3D 3200/4200 printer. HP’s Multi Jet Fusion technology is a new printing method that combines the materials in the dust bed with the help of heaters and heaters. The multi-element process produces pieces with tensile strength close to each other in the x-y plane and the z-axis by combining each layer.
HP 3D Printer Material PA12 has excellent mechanical properties that exceed the strength and density of the parts produced in other powder bed printing technologies. The power of the material makes MJF technology an excellent choice for functional parts such as automotive spare parts, white goods parts, high mechanical parts. Surface smoothness, finished and semi-gloss appearance make it a suitable material for precise detailed products and end user products. HP PA12 Plastic can be thought of as a general-purpose plastic with a wide range of applications.

Hp 3D Printer Material PA12 is a high-resolution PA12 material printed using black additive agent and heating lamps combined with PA12 powder. The printer output is dark gray in color. The material has high strength and density which is ideal for functional parts such as automotive parts. The surface is smooth and semi-bright, and is also an excellent choice for precision products and finished end-user products.
Sometimes, you may have a rougher surface than other surfaces. This is a characteristic of Multi Jet Fusion technology and depends on the geometry of your model and how it is driven during printing. Generally, the top surface will be roughest and the bottom surface will be smoothest. When planning a production, the application experience for quality and dimensional accuracy, depending on the application of the product, can be gained in a short time.
If your model has many faces with edges and / or corners, the edges and corners can be sharp. An accurate positioning to reduce this effect is also an experience gained in a short time.
Hp 3D Printer Material PA12 has a black core; this can be seen when a pattern is broken or drawn.
With MJF technology, you can produce very clean, precise, high-quality production and successful results even in hollow structures.
epending on the geometry of your model and the direction in which it is printed, you may see pressure lines or a stepped structure in your product if it is not well positioned. The step is a natural work of 3D printing and 3D printing works by pressing the layer layer. While the layers in this technology are about 0.08 mm thick, there is a step like a ladder between each layer. The step visibility varies between the top and bottom surfaces. Very little perceptible at the top, almost disappearing at the bottom.
How is 3D printing done with Hp 3D Printer?
Support Wall Thickness – Must be at least 0.4 mm thick
Unsupported Wall Thickness – Must be at least 0,5 mm thick
Supported Wires – Must be at least 0,8 mm thick
Unupported Wires – Must be at least 0,9 mm thick
Embossed details – Height and width must be at least 0.2 mm – At least 0.4 mm for readable text olmalı
Engraving Detail – Height and width must be at least 0,2 mm – Must be at least 0.4 mm for readable text
Exit Holes – must be at least 4.0 mm in diameter for an exit hole
When there are two or more escape holes, it should be at least 2.0 mm in diameter. For products larger than 50 x 50 x 50 mm.
The gap between the two parts, wall or wire must be at least 0,6 mm.
Prevent Wall Striking in Large Models
Large models with thin walls can be struck depending on the geometry of the part. The material is sintered at a high temperature and then cooled down to room temperature and shrunk. This shrinkage can create stress that can cause deformation in the material. Some geometries (eg wide flat parts, open boxes) tend to bend. In this case it is necessary to be more patient in the cooling phase.
Thicker Models Bending is More Hard
Bolder models are more difficult to bend. Flexibility depends on the structure and design of the model. As something thickens, it can not be so flexible. A spring made of 1 mm wire will be compressed and easily extended. A 3 mm thick spring makes a little more effort and does not compress when you drop it from a few meters.
Thicken Your Engraved / Embossed Text for Easy Reading
Although this material does not show 0.2 mm details, we see the text clearly visible in details of 0.5 mm. If you want clearer text or embossed details, try increasing the thickness to 0.5 mm.
Precision: ± 0.2 mm for features below 100 mm. For features over 100mm, 0.1% of the length is added.
