Resin Printing

Resin printing is an additive manufacturing technique that uses ultraviolet (UV) light to solidify layers of liquid resin, forming three-dimensional objects with high precision and fine detail. Key technologies include SLA (Stereolithography), which uses a laser to cure the resin, and DLP (Digital Light Processing), which uses a screen to solidify each layer one at a time. The process involves creating a digital model, slicing it into layers, and then the printer solidifies the resin layer by layer until the part is complete.

How it works

Model preparation: A 3D design is created and sliced ​​using specialized software, dividing the object into hundreds or thousands of thin layers.

Layer-by-layer printing: The printer platform is lowered into a container of liquid resin.

Photopolymerization: A light source (laser for SLA or projection screen for DLP) is activated and selectively solidifies the resin in the areas corresponding to each layer of the model.

Platform elevation: The platform is raised slightly to allow the resin to flow beneath the solidified layer, and the process is repeated until the part is fully printed.

Post-curing: After printing, the part is removed, washed with alcohol, and cured under UV light in a booth to achieve its final strength.
