Abstract

The invention belongs to the technical field of 3D printing, and provides a DLP UV-curing rapid molding edge processing method and device. The method comprises the steps of slicing and forming 3D models; observing the molding phenomenon, and obtaining the imaging plane edge halo size and the forming model edge curing condition; obtaining the model contour line, and adjusting the width of the modelcontour line according to the definite value to obtain contour edge lines with the width; conducting normal drawing and filling in a closed area defined by the contour edge lines with the width; andconducting drawing and filling in the contour edge lines with the width according to preset target grayscale to form a slice map for molding. According to the DLP UV-curing rapid molding edge processing method and device provided by the invention, curing caused by halo can be avoided effectively, and the curing rapid-molding edge precision is improved; and the molding speed is increased, and the grinding procedure is reduced.

Description

technical field

[0001] The invention relates to the technical field of 3D printing, in particular to a DLP photocuring rapid prototyping edge processing method and device. Background technique

[0002] Rapid prototyping technology is to use computer to decompose the three-dimensional model data into points or surfaces, and then accumulate materials from points to surfaces, and from surfaces to solids to obtain solid prototypes.

[0003] At present, there are three mainstream methods of rapid prototyping technology: photocuring rapid prototyping, hot melt extrusion and selective laser sintering. The model obtained by hot-melt extrusion molding and selective laser sintering has a rough surface and low precision, while the model obtained by SLA / DLP photo-curing rapid prototyping technology has a smooth surface and high precision, so the photo-curing rapid prototyping technology has been obtained. More people's favor.

[0004] Light-curing rapid prototyping technology uses lig...
