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
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
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.
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.
