ASA (Acrylonitrile Styrene Acrylate): a UV-stable production-grade FDM thermoplastic
Now you can build consistently high-quality parts, with exceptional UV stability and the best aesthetics of any FDM thermoplastic.
ASA is poised to become the most popular all-purpose prototyping material for users of Fortus. Matching or exceeding the mechanical properties of ABS, ASA may be your new favorite general prototyping material. Its UV-resistance makes it especially suited in production parts for outdoor commercial and infrastructure use. And its wide selection of colors and matte finish makes it ideal for attractive prototypes in consumer sporting goods, tools and automotive components and accessories.
| Standard lead time | About 4 working days, depending on part size, quantity, number of components and finishing degrees. |
|---|---|
| Standard accuracy | ±0.012 in (± 0.3 mm) - may vary depending on geometry. |
| Layer thickness | 0.005 in (0.127 mm) to 0.020 in (0.508 mm) |
| Minimum wall thickness | 0.039 in - 1 mm |
| Maximum build dimensions | Dimensions are unlimited as components may be composed of several sub-parts. The maximum build envelope is 3 x 2 x 3 ft (914 x 610 x 914 mm). |
| Surface structure | Unfinished parts typically have a rough surface but all kinds of fine finishes are possible. FDM/FFF parts can be smoothed, painted and coated. |
| Measure | Value | Test method |
|---|---|---|
| Tensile strength | 4 750 psi | 33 MPa | ASTM D638 |
| Tensile modulus | 290 000 psi | 2 010 MPa | ASTM D638 |
| Elongation at break | 9% | ASTM D638 |
| Heat deflection temperature (HDT) at 66 psi | 208 °F | 98 °C | ASTM D648 |
| Heat deflection temperature (HDT) at 264 psi | 196 °F | 91 °C | ASTM D648 |

We strongly recommend to our customers a good preparation of digital 3D files. This preparation will ensure the quality and optimal 3D printing of your files.
If your file has multiple assembled parts that contain overlaps, it is important to unify into a single solid file. If you are working with surface files and shells, it is important to transform the surface models into a solid format.
The quality of 3D files is very important. We prefer to work with parametric models. This allows us to optimize the resolution when creating .STL files for the best results.
If you decide to transform a parameterized file yourself into an .STL file, you must ensure that you have enough resolution to keep most of the characteristics. Otherwise, there is a risk of losing important functions of your 3D model.
We accept file formats: Solidworks, Catia, STEP, IGES, Parasolid (X_T, X_B), and .STL high resolution.
All processes have manufacturing limits. With 3D printing, the wall thickness has a direct impact on the selection of layer thicknesses. A simple rule to follow is to make sure you have wall thicknesses 4 times greater than the layer thicknesses.
The selection of layer thicknesses will influence three important aspects of a 3D printed part.
All manufacturing processes have a variation. When programming 3D files for 3D printing we make sure to manage the shrinking effects inherent in thermoplastics. We have a multitude of controls that reduce variation and provide exemplary repeatability with all of our technological processes.
Depending on the geometry of the parts, the tolerances vary around:
When producing multiple parts, it is possible to make changes to 3D files to achieve better accuracy.
Orientation orthogonal to the XY fabrication plane is important to maximize the accuracy of the part. We obtain greater precision in the X and Y axes.
