What is the Resin

The resin (organic polymer) is ideal for the creation of resistant parts, as it offers high toughness and impact resistance.

It provides a balance between resistance and conformity, making it perfect for parts to which high tension is applied. Also recommended for design checks and create quick fit connections.

Thanks to this resin, a level of detail and high precision tolerances are obtained that cannot be achieved with other materials. In addition, a resin printed part can be machined later.

Technology used

SLA, or stereolithography, is an add-on manufacturing process that uses an ultraviolet light laser in a tank to build objects from resin. It is used for the production of both definitive pieces and for the elaboration of models, prototypes or patterns.

In this case you must also have a 3D model, and this is built by cutting the file into thin layers with specialized software. A support structure is created, where necessary, to deal with overhangs and cavities.

Once the layer to be printed has been created, the lifting platform of the equipment descends a distance equivalent to the thickness of a layer of solidified resin (usually between 0.05 and 0.15 mm). A sheet sweeps the piece leaving a new layer of liquid resin on the surface of the tray, ready for the next laser impression. In this way, a three-dimensional piece is created layer by layer. Once the piece is completed, it is immersed in a chemical bath that removes excess resin and subsequently cured in an ultraviolet light oven.
