Three-dimensional model printing cost evaluation method and device

Abstract

The invention discloses a three-dimensional model printing cost evaluation method and device. The method includes the steps of obtaining geometrical data and printing data of a three-dimensional modelprinting sample; estimating the printing cost on the basis of the geometrical data and the printing data of the sample, and establishing a random forest model; using the random forest model to conduct data training; adjusting the characteristics of the random forest model many times to enable an out-of-bag error of a random forest to be the minimum; and estimating the printing cost of the three-dimension model on the basis of the adjusted random forest model. The random forest is utilized to perform cost predication issue modeling, the printing cost is predicated through a machine learning method, an automatic and accurate printing cost estimation scheme is provided, the manpower estimation cost is reduced, the dependence of a quotation system upon manpower is reduced, and the user experience is improved. Moreover, with the gradual increase of accumulated samples, the predication accuracy will become higher. Compared with the prior art, the three-dimensional model printing cost evaluation method and device have the advantages that the printing cost can be predicated automatically and the predication accuracy can be increased along with the increase of the accumulated samples.

Description

technical field [0001] The invention relates to the technical field of printing cost estimation and machine learning, in particular to a method and device for estimating the printing cost of a three-dimensional model. Background technique [0002] 3D printing applications have become more and more popular, and there are many cloud platforms at home and abroad that provide online order printing services. However, the printing price is affected by many factors, and it is difficult to provide accurate quotations in advance, resulting in low order processing efficiency. A large number of pre-sales and after-sales manual participation further increases the printing cost, making it difficult to promote the cloud order printing service on a large scale. At present, cloud platforms mostly use model volume calculation and manual experience estimation to calculate printing cost. There are two general forms: [0003] 1. After the user uploads the model, the system automatically calcu...
