Tailor-made and unique: glasses are the 3D printing’s ideal product
Surely now the only impediment in the home occur in many of the things that are possible to print in 3D is the cost of the printer, including the supply is still not cheap and that would justify the satisfaction of certain whims.
The 3D printing, however, could revolutionize not just the optics industry, today there is already a company that manufactures glasses from a 3D printer and one that actually also produces lenses.
The lenses are of incredible interest and implement them with a 3D printer would entice many. The glasses made with a technology called Printoptical out ready for use, the glasses can be obtained from non-prescription and prescription lenses.
The differences between un’occhiale made with classic and with the 3D printer techniques are still very pronounced, the lenses obtained in the construction process are shaped and set into the frame and those printed in 3D are one with the frame.
These are not the only differences between the two products, with the printer obtained lenses are of a single index of refraction that does not need for treatments. medium and high in organic refractive indices need of treatment resistant.
The anti-reflective coating is not possible to get it with a 3D printer because what you get with a PVD machine depositing metal vapors in altovuoto. The staining treatment is feasible, both total and nuanced.
The simple replacement of a lens is not possible, there is no distinction between the lens and the frame. It must be said that the realization of the separate lenses would be possible as well as that the eyeglasses but would be useless because of the complexity of assembly work (unless who purchases the printer is not an optical).
Check the diopter obtained is only possible thanks to a lensmeter and there is then to consider a number of technical parameters such as interpupillary distance and alignment of the visual field.
The sviluppatti glasses with this technology would hypothetically suitable to replace those that are graded in pharmacies and in supermarkets, for those in which the lens material is not a polymer is still not a subject of research.
The quality of the lenses obtained by the Printoptical technology seems to be of good quality, the possibility of seeing convex surfaces with unaesthetic steps has been overcome thanks to a suitably studied process.
