+ hybrid 3D printer
The novel hybrid 3D printer is based on the FFF technology, initially developed by Prusa. Though FFF technology is nowadays rapidly evolving, it is already been a consolidated reality for quite a long time in the 3D printing community. Nevertheless such technology shows several drawbacks, as regards printed items’ quality and precise positioning of the mechanical axes.
Among the various features of the innovative 3D printer designed by Design Lab Frosinone, several technical solutions have been purposely designed with the aim of improving the printing quality: taking advantage of specifically designed mechanical joints, it has been possible to achieve step resolutions as fine as ~0.5 μm along each of the three motion axes ( 53 μm for ten steps). The extruder features a 0.15 mm steel nozzle, capable of producing 0.16 mm drops. The final resolution of the printer is then greatly improved, as compared with a resin-marble mixture being instantly “frozen” under a beam of light, thus allowing to produce premium quality objects.
