Embodiment Construction

[0030] Figure 1 to Figure 4 An example of a three-dimensional printing apparatus is shown. The device may also be referred to as a stereo-printed 3D printer or a stereo-printed additive manufacturing device. The basic components of the device are a base part 101 and a cover 102, the cover 102 being movably coupled to the base part 101 so that the cover 102 can be figure 1 and figure 2 Closed position shown with image 3 and 4 Move between the open positions shown. Here, the direction of movement is vertical, but this is not necessary; the movement of the cover 102 relative to the base part 101 can take place in other directions. An important advantage of such a removable cover is that by closing the cover 102, the ongoing stereolithographic 3D printing process can be protected from any external optical radiation.

[0031] A groove 401 is provided in the base portion 101 for holding resin used in the stereolithographic 3D printing process. If the slot 401 is not a fixe...

Abstract

A stereolitography apparatus comprises a fixed vat (401) or a holder for receiving a removable vat for holding resin during stereolithographic 3D printing, and a radiation source (501) for generating radiation capable of polymerizing portions of said resin in said vat. (401). The apparatus comprises a shutter (502) between said radiation source (501) and said vat (401) for allowing only selected portions of the generated radiation to reach said resin, and a cooling channel (503) between said radiation source (501) and said shutter (502). The apparatus comprises a blower (504) configured to force coolant gas through said cooling channel (503).

Description

technical field [0001] The present invention relates to three-dimensional printing 3D printing technology, also known as three-dimensional printing additive manufacturing. In particular, the invention relates to the task of controlling the temperature of a shutter in a three-dimensional printing apparatus. Background technique [0002] Stereoprinting is a 3D printing or additive manufacturing technique in which light radiation is used to photopolymerize suitable raw materials to produce desired objects. The raw material enters the process in the form of resin. The groove is used to hold a certain amount of resin, and the build platform moves vertically so that the target to be produced grows layer by layer from the build surface of the build platform. Light radiation for photopolymerization can come from the tank from above, in which case the build platform moves down through the remaining resin as fabrication progresses. This specification relates in particular to the so...
