【摘要】：3D打印如今已然從實(shí)驗(yàn)室開(kāi)始走向了市場(chǎng),消費(fèi)級(jí)別的3D打印機(jī)也經(jīng)常出現(xiàn)在眼前,這項(xiàng)集合了材料與機(jī)械領(lǐng)域科學(xué)知識(shí)的產(chǎn)品開(kāi)始顛覆了過(guò)去的制造思路,為未來(lái)的生產(chǎn)提供了另一種思路。從數(shù)字技術(shù)角度來(lái)看,3D打印是一種將三維模型通過(guò)數(shù)據(jù)處理轉(zhuǎn)化成為片層,這樣就將原本的復(fù)雜數(shù)據(jù)轉(zhuǎn)化為可以直接被機(jī)器識(shí)別的語(yǔ)言,然后通過(guò)可塑材料快速層層塑形。這種對(duì)數(shù)字化模型切片的過(guò)程需要軟件預(yù)先進(jìn)行處理才能用于打印,目前這種軟件一般分為商業(yè)版和開(kāi)源版本,前者往往價(jià)格不菲,而且由于是單獨(dú)開(kāi)發(fā)出來(lái)的,所以通用程度較低,不實(shí)用于當(dāng)下的工業(yè)化,但是另一種開(kāi)源的切片軟件,大多需要依賴(lài)源代碼發(fā)布者提供技術(shù)上的支持,而且普遍只是對(duì)語(yǔ)言包進(jìn)行了漢化。從軟件上來(lái)說(shuō),3D打印缺少了技術(shù)支持,在這種情況下是比較難跟上國(guó)外的發(fā)展進(jìn)度的,所以為了改變這一現(xiàn)狀,本文著力研究底層算法,通過(guò)自主開(kāi)發(fā)基于STL格式的軟件,來(lái)填補(bǔ)當(dāng)下國(guó)內(nèi)3D打印切片步驟中的空缺。本文通過(guò)立足于國(guó)內(nèi)外的研發(fā)進(jìn)度,在對(duì)比了國(guó)內(nèi)外的數(shù)字軟件支持程度后,結(jié)合國(guó)內(nèi)總體情況研究軟件的總體發(fā)展方案。其次,詳細(xì)闡述了3D打印軟件底層算法的幾個(gè)核心模塊算法的分析和設(shè)計(jì),實(shí)現(xiàn)了對(duì)三維模型的導(dǎo)入、分層切片、自動(dòng)添加支撐、加工路徑優(yōu)化和GCode生成的功能。然后使用DEV-C++開(kāi)發(fā)環(huán)境和OpenGL圖形接口開(kāi)發(fā)了軟件界面,實(shí)現(xiàn)了3D打印參數(shù)的設(shè)置、模型的幾何變換以及不同顯示模式之間的切換,而且以軟件設(shè)計(jì)中的關(guān)鍵節(jié)點(diǎn)為例,分析數(shù)據(jù)處理的手段。最后用實(shí)際打印來(lái)檢驗(yàn)軟件的實(shí)用性和可靠性。通過(guò)最終的測(cè)試結(jié)果總結(jié)發(fā)現(xiàn),本文提出的算法是符合條件,并且將模型切片的計(jì)算性能較好,支持多種修改。
[Abstract]:3D printing has now moved from the laboratory to the market, and consumer-level 3D printers are often in front of us, a product that brings together scientific knowledge in the field of materials and machinery to upend the way in which it used to be made. For the future of production to provide another way of thinking. From the point of view of digital technology, 3D printing is a kind of transformation of 3D model through data processing to a lamellar layer, so that the original complex data can be transformed into a language that can be recognized directly by the machine, and then the plastic material can be quickly formed layer by layer. This process of slicing digital models requires pre-processing of software to be used for printing. At present, this software is generally divided into commercial versions and open source versions, which are often expensive and because they are developed separately. So the degree of generality is low and not suitable for the current industrialization, but another open source slicing software mostly relies on the technical support of the source code publishers, and generally only the Chinese version of the language package. There is a lack of technical support for 3D printing in software. In this case, it is difficult to keep up with the development of foreign countries. Therefore, in order to change this situation, this paper focuses on the underlying algorithm, through the development of software based on STL format. To fill the gaps in the current domestic 3D print slicing process. In this paper, based on the domestic and foreign R & D progress, after comparing the domestic and foreign digital software support, combined with the overall domestic situation to study the overall development of the software. Secondly, the analysis and design of several core module algorithms of the bottom algorithm of 3D printing software are described in detail, and the functions of importing 3D model, slicing layers, automatically adding support, optimizing machining path and generating GCode are realized. Then the software interface is developed by using the DEV-C development environment and the OpenGL graphic interface, which realizes the setting of 3D printing parameters, the geometric transformation of the model and the switching between different display modes, and takes the key nodes in the software design as an example. Analysis of the means of data processing Finally, the practicability and reliability of the software are verified by actual printing. Through the final test results, it is found that the algorithm proposed in this paper is in accordance with the conditions, and the computational performance of the model slicing is better, which supports many modifications.
