New 3D printing technique: SLA 3D Printing

New possibilities

By applying our new SLA 3D printing technique, we can print even more accurately and smoother than we are used to with FDM 3D printing. The material we use is a liquid epoxy resin that cures after being exposed to UV light.

Because our SLA 3D printers use high resolution screens, we can produce very accurate objects and because the material is liquid, this ensures smooth surfaces and no visible print lines.

The material '' Ultra Detail Resin ''

Our new material for these SLA 3D printers is Ultra Detail Resin, it is an epoxy resin with a relatively low viscosity, which ensures that the layer adhesion is strong and the surfaces have a smooth appearance. The material is quite flexible with thin plates or rods, once the product is thicker the material does not bend much and ensures that the product is sturdy and solid.

As we described above, the epoxy resin cures by exposure to UV light, after exposing each 3D printed layer, the 3D print is ready to be cleaned.

Cleaning and curing after SLA 3D printing

After the SLA 3D printing has gone well, we proceed to cleaning the 3D prints, this is done by placing the products in an alcohol bath. Our 3D printing washing machine creates a whirl in the alcohol bath so that the remaining resin that is still on the 3D printed product is washed off.

The next step is to further cure the product, we do this by exposing it again to strong UV light. Curing takes a few minutes, when this is done the material further strengthens and is ready to be used by the customer.
