Abstract

The invention provides a light source component and a 3D (three-dimensional) printer and relates to the field of light source components. The light source component comprises a light source substrate, a bottom plate and a reflecting component, wherein the light source substrate is connected with the bottom plate; the reflecting component comprises a plurality of light-penetrating pipes which are connected with one another and are connected with the light source substrate; a fluid passage is arranged between the pipe walls of the plurality of light-penetrating pipes and the bottom plate for heat-dissipating fluid and consists of the pipe walls of the light-penetrating pipes and the bottom plate; or the reflecting component is also provided with a heat-dissipating pipe which serves as the fluid passage. The light source component provided by the invention has a heat-dissipating cooling function, and meanwhile, the volume of the whole module can be reduced. The 3D printer provided by the invention adopts the light source component, so that the 3D printer is small in volume, has the heat-dissipating cooling function and is long in service life.

Description

technical field [0001] The present invention relates to the field of light source components, in particular, to a light source component and a 3D printer. Background technique [0002] SLA is the earliest practical rapid prototyping technology, using liquid photosensitive resin raw materials. The process is to first design a three-dimensional solid model through CAD, use a discrete program to slice the model, design the scanning path or the image required for development and exposure, and the generated data will precisely control the laser scanner (or LCD / DLP through the display image. Exposure) and the movement of the lifting table; the beam passes through the scanner controlled by the numerical control device, and irradiates the surface of the liquid photosensitive resin according to the designed scanning path, so that a layer of resin in a specific area of ​​the surface is cured. When a layer is processed, the part is generated A section of a section; then the lifting ta...
