A little 3D printing knowledge,


For the general public, 3D printing mainly uses FDM (Fused Deposition Modeling) technology which is a process of successive deposition of a molten material such as plastic PLA, ABS, PETG, Nylon and more … This is not the only one! Thus, there is another technology, more complex, using resin and which begins to make its place in force in the 3D printers world.

Resin printers use the SLA technique, it uses a laser which is redirected by mirrors mounted on galvanometers. This makes it possible to trace the shape of the model to be printed on a layer of liquid resin.

The laser then traverses the entire surface to polymerize the resin and thus solidify it. This therefore implies that the larger the surface to be printed, the longer the laser travel time.

The primary advantage of this technology is the laser. It will not suffer from the same variances in precision. Since the laser is moved using galvanometers, its initial tracing dimension does not vary depending on its position on the printing surface. It is in particular for this reason that it is more interesting to print large detailed models or a multitude of small models on an SLA printer.

We can offer several styles of 3D printing methods in a multitude of materials.
