Problems solved by technology

[0016] Therefore, the impossibility of using high-strength polymeric materials becomes a special limitation
[0017] Furthermore, in some examples, objects produced by known 3D printing methods, especially selective laser sintering techniques, have irregular and grainy surface finishing methods, so that further processing steps are required, which leads to increased production costs
[0018] Furthermore, traditionally used decorating techniques are very complex and expensive and do not allow reliable material effects

Embodiment Construction

[0031] Method for three-dimensional printing, especially for the manufacture of windows, for floors or similar plate-shaped elements, comprising:

[0032] - at least one step of providing PVC and at least one solvent, wherein PVC is soluble;

[0033] - at least one step of mixing said PVC and said solvent to obtain a mixture of at least one liquid phase;

[0034] - at least one step of dispersing said mixture onto at least one deposition surface 1;

[0035] - at least one evaporation step of said solvent to obtain at least one PVC layer 2 of at least one finished product 3, which is followed by said dispersion step.

[0036] According to the invention, said method also includes repeating said dispersion step and said evaporation step to obtain a plurality of overlapping layers 2 of PVC forming said finished product 3 .

[0037] Usefully, the finished product 3 obtained according to the method is a decorative surface part for a window frame profile member 4a, or alternatively...

Abstract

A process for three-dimensional printing, particularly for the production of windows, plate-shaped elements for floors or the like, comprises: a supply step of PVC and of a solvent in which the PVC issoluble; a mixing step of the PVC and of the solvent to obtain a mixture in the liquid phase; a distribution step of the mixture onto a deposition surface (1); an evaporation step of the solvent forobtaining a layer of PVC (2) of a manufactured article (3), wherein the evaporation step is subsequent to the distribution step; and repeating the distribution step and the evaporation step to obtaina plurality of overlapping layers of PVC (2) forming the manufactured article (3).

Description

technical field [0001] The invention relates to a method for three-dimensional printing, in particular for the manufacture of windows, for floors or similar plate-shaped components. Background technique [0002] In recent years, 3D printing technology for objects of different shapes and uses has become more widely used. [0003] The very innovative technique, still in the process of being perfected, enables the fabrication of objects with geometries that are difficult to achieve with traditional fabrication methods through additive fabrication methods. [0004] Examples of industrial 3D printing processes include selective laser sintering, stereolithography, and polyjet using photopolymers. [0005] Selective laser sintering uses laser light to sinter thermoplastic, metallic or silicon powders. [0006] This type of method consists, in fact, of using a device that, through a special dispersion system, disperses layers of powder onto the surface of an object that gradually ...
