High visual impact prototypes
Stereolithography produces three-dimensional models of high visual impact using resins that resemble plastic materials such as ABS, clear polycarbonate or polypropylene.
It is a rapid prototyping technology that implements the principle of additive manufacturing using the heat generated by a laser to solidify the photosensitive resin only where it is needed to realize the object.
The modelling starts at the base of the object and move upwards by 0.1mm-thick layers until the object is fully formed. Once complete, the parts are subjected to UV treatment in a dedicated furnace to stabilize the resin and give it characteristics similar to the final material.
Additive manufacturing technologies produce almost no waste material. Liquid resin still in the tank of the machine and unaffected by the solidification process can be reused. Therefore the only waste elements are eventual supports, i.e. light mesh structures which the software automatically elaborates to guarantee the stability of parts of the object during the production process and which are easily manually removed by the operator.
The material is extremely workable signs of the supports and layering are eliminated in order to obtain a smooth surface suitable for a great variety of finishes, including paint, metallization or screen-printing. For this very reason, we can refer to objects realized by stereolithography as high visual impact prototypes. We can therefore create models very similar to final injection moulded pieces to be used at trade fairs, in the preparation of catalogues and their images or in sales force promotional materials.
Here some of the technical details, with our stereolithography machines, we can produce monolithic prototypes of up to 750x650x550mm to an accuracy of ± 0.05mm via ENVISIONTEC technology or pieces that can resist temperatures of up to 140°C with the material HTM140.
