3D Printing in ASA

ASA (Acrylonitrile Styrene Acrylate) is an advanced thermoplastic widely used in 3D printing, especially valued for its weather resistance and UV stability. It is ideal for outdoor applications where sun exposure and the elements can pose a challenge. Additionally, it offers excellent dimensional stability, making it perfect for functional parts that need to retain their properties in demanding conditions.

This compound stands out for its high impact resistance and long-term durability. This makes it an excellent choice for projects that require sturdy parts, both outdoors and in industrial applications.

Advantages of ASA

When is the perfect material choice?
Excellent weather and UV resistance, ideal for outdoor applications.
Heat deformation resistant, similar to ABS but with greater durability.
Easy to post-process, allows sanding and painting for custom finishes
Good dimensional stability, ideal for prototypes and functional parts
Smooth and high-quality finish, with post-processing options such as sanding and painting.
High impact resistance, making it durable in adverse conditions

Disadvantages of ASA

When to look for other material options
It is not biodegradable, which can be a drawback for those seeking sustainability
Not ideal for parts that require high mechanical strength
Less economical than PLA or PETG
It can emit odors when heated, a disadvantage in enclosed spaces
Fewer color options compared to other more commercial filaments.
Es poco flexible, no recomendado si tiene lengüetas o pestañas

Technology used

FDM, or fused deposition modeling, is a manufacturing process used for prototyping and the production of small to medium runs. This modeling uses an additive function, depositing the material in layers to shape the part.

A filament is used that is initially stored in rolls, and is fed into a nozzle that is above the melting temperature of the material and can move in three axes controlled electronically. The nozzle moves to deposit the material in the correct location, drawing the model line by line. Once a layer is drawn, the base lowers by a layer thickness (0.1-0.4) so that the printer can continue with the next layer.

When the model to be printed has sections that protrude or have a steep angle, a support structure is created where necessary and is printed in a material that can later be easily removed, in some cases soluble. This is done to ensure that the model does not hang in the air, thus preventing the layer from falling.
