Abstract
Description
The present invention relates to a three-dimensional printer having a digital hologram apparatus, and more particularly, to a three-dimensional printer having a digital hologram apparatus, To generate a predicted stereoscopic image of the output, thereby enabling the user to visually confirm the predicted data of the output, and to provide a technique for comparing the output data with the predicted data more intuitively using a sidewall camera Dimensional printer equipped with a hologram device.
Recently, three-dimensional printing technology has been attracting attention in the prototype development stage or small quantity production of various kinds of products at the prototype development stage.
3D printing is performed by analyzing the three-dimensional shape of an object through a three-dimensional graphic design program and generating a combination of two-dimensional cross-sectional shape data. Then, raw materials such as ABS and PLA It is a technique of forming a three-dimensional shape of an object by forming it on an output bed by various methods.
In the three-dimensional printing, there are a FDM (Fused Deposition Modeling) method or a FFF (Fused Filament Fabrication) method in which a raw material is extruded and sequentially laminated on an output bed to realize a three-dimensional shape. The powder is melted with a high- There are various SLS (Selective Laser Sintering) systems for realizing a three-dimensional shape, and SLA (Stereolithography Apparatus) systems for projecting a laser beam into a water tank containing a liquid photocurable resin.
A three-dimensional printer using the FDM method or the FFF method, which is a conventional laminate shaping method, uses a method of extruding raw material directly onto an output bed and molding it. However, when the output object is a three-dimensional scanner Dimensional modeling file provided by a computer program or an application, the size information of the model displayed on the program can be obtained only when the output is not actually intuitively known, .
Also, in order to confirm whether the finished model matches with the original model which is to be pulled, in order to confirm the model in the eyes or to use an auxiliary mechanism such as vernier caliper, scale, etc., There was an inconvenience.
SUMMARY OF THE INVENTION The present invention has been made to overcome the above-mentioned problems, and it is an object of the present invention to provide a technique for allowing a user of a three-dimensional printer to visually confirm the expected data of an output product.
It is another object of the present invention to provide a technology that can more intuitively compare the output with the expected data using the internal side wall camera of the 3D printer.
As a means for solving the above-mentioned technical problem, there is proposed, as a means for solving the technical problem, a laser generating apparatus provided on the inner side wall of a three-dimensional printer and projecting a stereoscopic image onto an output bed from the laser generating apparatus, The present invention provides a technique that allows the user to visually confirm the expected finished shape of the output more intuitively.
The present invention also provides a technique for comparing photographs of a stereoscopic image projected using an inner side wall camera and photographs of an output finished output, and judging whether the originally intended output is correctly output.
The present invention can more intuitively determine the size and error of a model to be output when a user of the three-dimensional printer executes the output.
