Additive manufacturing machines: 3D printers SLA technology with LASER light source and LED with a DLP®.

The 3D printers developed by ESC are based on stereolithographic technology (SLA) and use a light source in the UV field to produce objects by curing photosensitive resins.
The principle is the one of additive manufacturing, where a virtual 3D model of the object to be built is sliced into layers of defined thickness, generating several 2D profiles that will then be printed in sequence on top of each other to generate the physical object.

DLP 75-50
The SLA DLP 75-50 printer uses a LED light source and through a DLP® projector designs 2D images, obtained by slicing the 3D model, on the bottom of a vat containing resin solidifying it in illuminated areas. A platform, moved by a precision axis, rises above the liquid resin every time a layer is completed. In the end, the platform moves away from the liquid resin allowing the finished object to be discharged.
The DLP 75-50 printer, using Texas Instrument's DLP® system, is able to solidify the entire resin layer at each exposure (a few seconds of duration) allowing a high printing speed and is able to produce small parts with high resolution.

380B LASER
The SLA 380B LASER printer uses a laser source whose beam, through an optical system composed of a galvanometer scanner head and a field lens, draws the 2D profiles obtained by slicing the 3D model on the free surface of the resin. A platform, moved by a precision axis, supports the various layers printed by lowering in the liquid resin every time a layer is completed. In the end, the platform resurfaces from the liquid resin allowing the finished object to be discharged.
The 380B LASER printer uses a laser system to produce large parts with medium-high resolution.

The machine complies with the applicable European standards.
