Abstract
The invention is a stereolithography machine (1) comprising the following: a support plate (2) provided with a hole (2a); a container (3) associated with the support plate (2) and comprising a transparent bottom (3a); a radiation source (4) arranged below the support plate (2) and suited to convey a radiation beam towards the transparent bottom (3a) through the hole (2a); a temperature control unit (5) suited to maintain the support plate (2) at a predetermined temperature.
Claims13
A stereolithography machine comprising:
- a container suited to contain a fluid substance, said container having a transparent bottom;
- a support plate provided with a hole, said support plate being designed to house said container so that said transparent bottom faces said hole;
- a radiation source arranged below said support plate, said radiation source suited to convey a radiation beam towards said transparent bottom through said hole;
- and
- a temperature control unit suited to maintain said support plate at a predetermined temperature,
- wherein said support plate at said predetermined temperature maintains said container and said fluid substance at said predetermined temperature.

A stereolithography method comprising the following operations:
- preparing a fluid substance suited to solidify when exposed to a predetermined radiation beam;
- preparing a container suited to contain said fluid substance, said container having a transparent bottom;
- filling said container with said fluid substance;
- housing said container in a support plate provided with a hole for the passage of said radiation beam so that the transparent bottom of said container faces said hole;
- conveying said radiation beam towards said transparent bottom through said hole;
- providing a temperature control unit;
- said temperature control unit heating said support plate to a predetermined temperature;
- and
- said support plate at said predetermined temperature heating said container and said fluid substance, to said predetermined temperature,
- wherein said fluid substance is a mixture of different components that tend to separate at room temperature, and
- wherein said predetermined temperature is suited to prevent said separation of said components.
