A method and system for calculating the consumption of 3D printing model consumables

Abstract

The invention discloses a method and system for calculating consumables of a 3D printing model, which searches for all hollow structures on the 3D printing model, and fills the ones smaller than the set area to generate the first 3D printing model; the method along the surface of the first 3D printing model Extend outward with the first offset distance to generate a second 3D printing model; use a ball with a set diameter to traverse the surface of the second 3D printing model, and connect the surfaces formed by all the contact points of the ball during the traversal process to form the second 3D printing model Three 3D printed models were used as final consumable calculation models. Through the above steps, materials that cannot be nested in the same batch of printing of small pieces, nesting gaps between large and small pieces, and grooves on the surface of the second 3D printing model that are smaller than the diameter of the ball, etc. are also counted as the 3D printing. The consumable part of the model fully takes into account the fact that in the nylon SLS process, the heated nylon powder that does not participate in the molding is still counted as a consumable, so as to achieve accurate calculation of consumables.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a calculation method and system for 3D printing model consumables. Background technique [0002] 3D printing technology (also known as additive manufacturing technology) is a collective name for a series of rapid prototyping technologies. It is based on digital model files and uses bondable materials such as powdered metal or plastic to print layer by layer. techniques for constructing objects. [0003] Among them, selective laser sintering (SLS) technology is a high-tech 3D printing technology that integrates the latest achievements in the fields of CAD / CAM, numerical control technology, laser processing technology, and material science. Applying this technology, through laser irradiation, powder materials can be bonded into layers and stacked layer by layer, so as to realize rapid prototyping of products. Compared with 3D printing technologies of polymer mater...
