下邊我們幫各位老板一一梳理清楚，一篇文章讓你全面了解3D打印砂型鑄造技術(shù)！

什么是砂型3D打?。?/h2>

砂型3D打印是一種比較新的技術(shù)，簡單來說，就是像搭積木一樣，用特殊的材料一層一層地 “堆” 出鑄造用的砂型。

以前傳統(tǒng)的做砂型方法，可能需要先做模具，再用模具去造型，過程比較復(fù)雜，而且如果要做一些形狀很奇怪、很復(fù)雜的砂型，就會特別困難，成本也高。但砂型 3D 打印就不一樣了，它是通過電腦里的三維模型來工作的。你把設(shè)計好的鑄件三維模型數(shù)據(jù)輸入到 3D 打印機里，打印機就會根據(jù)模型的形狀和結(jié)構(gòu)，把特殊的沙子或者類似沙子的材料，按照一層一層的方式精準地鋪放和粘結(jié)起來，就像用無數(shù)個很薄的 “沙片” 逐漸搭建成一個完整的砂型。這樣，不管是多么復(fù)雜的形狀，只要能在電腦里設(shè)計出來，它都能打印出來，而且速度還挺快，也不需要像傳統(tǒng)方法那樣制作復(fù)雜的模具，能節(jié)省很多時間和成本呢。

砂型3D打印機原理

砂型3D打印通常采用粘結(jié)劑噴射技術(shù)（Binder Jetting, BJ），其基本原理如下：

1. 鋪砂：打印機在打印平臺上均勻鋪設(shè)一層特定的鑄造用砂（如硅砂、陶瓷砂或覆膜砂）。
2. 噴射粘結(jié)劑：噴頭按照計算機模型（CAD數(shù)據(jù)）精確噴射粘結(jié)劑，使特定區(qū)域的砂粒粘結(jié)在一起。
3. 重復(fù)堆積：平臺下降，再次鋪砂并噴射粘結(jié)劑，逐層固化成型，直至整個砂型打印完成。
4. 后處理：去除未粘結(jié)的松散砂料，對打印出的砂型進行硬化、清理，隨后即可用于金屬澆鑄。

3D打印砂型鑄造解決哪些核心問題？

每一項技術(shù)的存在或誕生必定是有它的“使命”。通俗來說就是解決了特定問題，滿足了市場需求，這就是它存在的價值。下邊我們來看看砂型3D打印技術(shù)解決了哪些傳統(tǒng)鑄造遇到的棘手問題，如下：

• 復(fù)雜形狀零件制造：傳統(tǒng)砂型鑄造制造復(fù)雜形狀模具難度大、成本高，像航空發(fā)動機葉片內(nèi)部精細冷卻通道，傳統(tǒng)工藝難以精準成型。3D 打印砂型依據(jù)數(shù)字模型，能輕松將復(fù)雜形狀變?yōu)楝F(xiàn)實，從帶有密集內(nèi)凹、凸起的汽車發(fā)動機缸體砂型，到有著精妙仿生結(jié)構(gòu)的醫(yī)療器械外殼砂型，都能完美呈現(xiàn)。
• long production lead time：傳統(tǒng)砂型鑄造需經(jīng)歷設(shè)計模具、制造模具、調(diào)試模具等冗長流程，大型模具制造周期常超數(shù)月。3D 打印砂型無需模具制作，直接按數(shù)字模型打印，設(shè)計修改也只需在電腦上操作模型，重新打印即可，能大幅縮短生產(chǎn)周期。如研發(fā)新款汽車發(fā)動機缸體時，傳統(tǒng)鑄造模具報廢重制至少兩周，3D 打印砂型當天就能完成新模型打印，次日即可投入鑄造。
• Difficulty in cost control：傳統(tǒng)鑄造模具制造材料浪費嚴重，復(fù)雜模具材料利用率不足 30%，且人工成本高。3D 打印砂型按需打印，精準用砂，材料利用率超 90%，減少浪費。打印過程自動化程度高，可降低人力成本。以小型鑄造廠為例，年產(chǎn)能 5000 件小型管件鑄件，引入 3D 打印砂型后，材料成本年降 15 萬元，人工成本削減 20 萬元。
• 鑄件精度低：傳統(tǒng)砂型因模具磨損、分型面貼合誤差等，鑄件尺寸偏差常超 ±1mm，后續(xù)機加工余量多、材料浪費大，且易出現(xiàn)局部疏松、夾砂等缺陷，導(dǎo)致鑄件力學性能不均。3D 打印砂型由數(shù)字化模型精準驅(qū)動，砂型尺寸精度可達 ±0.5mm 以內(nèi)，能實現(xiàn)均勻緊實，避免砂粒松散不均，同時優(yōu)化凝固過程，大幅減少縮孔、縮松，保障鑄件內(nèi)部質(zhì)量穩(wěn)定可靠。
• 環(huán)保壓力大：傳統(tǒng)鑄造的模具制造產(chǎn)生大量廢金屬、廢塑料，砂型處理后廢砂堆積如山。3D 打印砂型生產(chǎn)中，未使用的砂可回收再利用，廢棄物極少，且打印過程無需大量化學粘結(jié)劑，減少有害氣體揮發(fā)，改善車間環(huán)境。據(jù)統(tǒng)計，采用 3D 打印砂型后，鑄造車間廢棄物排放降低超 80%，粉塵、有害氣體濃度達環(huán)保標準。

鑄造廠如何評估是不是需要買砂型3d打印機？

一臺砂型3D打印機的價格不便宜（通常來說尺寸越大越貴），要購買的話相對是比較謹慎的，特別是中小型鑄造廠。為了幫助老板們評估一下是否有購買的必要，我們特地整理出了下邊的一些評估要點，給傳統(tǒng)鑄造廠的老板們一個參考，然后根據(jù)自己的情況來決定要不要購買：

生產(chǎn)需求

• 產(chǎn)品復(fù)雜度：若鑄造廠經(jīng)常生產(chǎn)復(fù)雜形狀、有精細結(jié)構(gòu)或內(nèi)部通道的鑄件，如航空發(fā)動機葉片、汽車缸體等，傳統(tǒng)工藝難以滿足要求，砂型3D打印機能發(fā)揮優(yōu)勢。
• 生產(chǎn)規(guī)模與批量：對于小批量、多品種的鑄件生產(chǎn)，砂型 3D 打印機可靈活快速切換產(chǎn)品，無需制作模具，能降低成本和周期。但大規(guī)模、單一品種的鑄件生產(chǎn)，傳統(tǒng)工藝可能更具成本效益。
• 交貨期要求：若客戶對交貨期要求嚴格，砂型 3D 打印機可縮短生產(chǎn)周期，快速響應(yīng)訂單。

cost-effectiveness

• 設(shè)備投資：需考慮砂型 3D 打印機的購買成本、安裝調(diào)試費用及后期維護成本。
• 運行成本：包括打印材料、能源消耗、人工成本等。對比傳統(tǒng)鑄造工藝，分析長期運行成本的高低。
• 潛在收益：考慮使用砂型 3D 打印機后，因產(chǎn)品質(zhì)量提升、生產(chǎn)周期縮短、廢品率降低等帶來的潛在收益。

技術(shù)能力

• 員工技能：評估現(xiàn)有員工對 3D 打印技術(shù)的掌握程度，是否需要培訓或招聘專業(yè)人才。
• 技術(shù)支持：了解設(shè)備供應(yīng)商的技術(shù)支持能力，包括安裝調(diào)試、培訓、故障維修等服務(wù)是否及時有效。

市場競爭

• 行業(yè)趨勢：關(guān)注同行是否已采用砂型 3D 打印技術(shù)，若競爭對手已應(yīng)用并獲得優(yōu)勢，為保持競爭力，鑄造廠可能需要考慮購買。
• 客戶需求：了解客戶對產(chǎn)品的新要求和期望，若客戶希望看到鑄造廠采用先進技術(shù)提升產(chǎn)品質(zhì)量和生產(chǎn)效率，購買砂型 3D 打印機有助于滿足客戶需求，提高市場競爭力。

環(huán)保要求

• 如果當?shù)丨h(huán)保要求嚴格，傳統(tǒng)鑄造工藝在廢砂處理、廢氣排放等方面壓力大，砂型 3D 打印機因材料利用率高、廢棄物少等優(yōu)勢，有助于企業(yè)滿足環(huán)保要求。

I. High-precision and complex structure manufacturing capability

Sand mold 3D printers are able to create sand molds with extreme precision, which is essential for producing high-quality castings. While traditional methods of sand mold making are often overwhelmed by the complexity of the structures, 3D printing makes it easy. It is able to accurately reproduce every detail of a design drawing, whether it is a complex internal cavity, a fine texture or a thin-walled structure. This high-precision manufacturing capability not only improves the dimensional accuracy and surface quality of the castings, but also reduces subsequent machining processes and production costs. For example, in the aerospace field, some key components require extremely high precision, and sand mold 3D printers can produce sand molds that meet strict standards, thus ensuring the quality and performance of the final casting, and meeting the demanding requirements of aerospace products for safety and reliability.

II. Shortening the production cycle

The traditional sand mold production process is usually more cumbersome, need to go through the mold design, production, assembly and other aspects, consuming a lot of time. Sand mold 3D printer greatly simplifies this process, it can be directly based on the digital model of the sand mold layer by layer printing, without the need to make molds and complex assembly operations. This shortens the production cycle significantly, enabling companies to bring products to market faster and seize the first opportunity. Taking automobile manufacturing as an example, the development cycle of new models is often very tight, sand mold 3D printer can make sand molds for automobile engines and other parts in a short period of time, accelerating the trial production process, helping enterprises to verify and optimize their products faster, and improving the overall research and development and production efficiency.

III. Cost reduction

The purchase of a sand mold 3D printer requires a certain initial investment, but in the long run, it can bring significant cost reductions for enterprises. On the one hand, as mentioned earlier, it reduces the mold making and assembly in the traditional sand mold making process, reducing labor costs and mold costs. On the other hand, as 3D printing can realize high-precision manufacturing, it reduces the scrap rate and subsequent processing costs. In addition, 3D printing technology can also optimize the design of the sand mold, so that it meets the requirements of the premise of more lightweight, thus reducing the use of casting materials, further reducing costs. For some small batch but a variety of products for the enterprise, sand mold 3D printer cost advantage is more obvious, because it does not need to make a special mold for each product, greatly reducing the production cost and inventory pressure.

IV. High degree of design freedom

Sand mold 3D printers offer designers a high degree of design freedom. Traditional manufacturing processes are often limited by the structure of the mold and the manufacturing method, and designers need to consider many process factors when designing a product, thus compromising the design. 3D printing technology, on the other hand, breaks down these limitations and allows designers to give full play to their imagination and design more innovative and unique product structures. For example, they can design castings with complex internal runners to optimize product performance, such as improving heat dissipation efficiency or fluid flow performance. This increased design freedom not only helps companies develop more competitive products, but also promotes innovation in the industry as a whole.

V. Personalization

With the diversification of market demand and the trend of individualization becoming more and more obvious, personalized customization has become an important development direction of the manufacturing industry. Sand mold 3D printer can precisely meet this demand, it can according to the customer's specific requirements, quickly create a unique sand mold, to achieve personalized custom production. Whether it is a single piece of customization or small batch customization, sand mold 3D printer can easily deal with. This is important for some high-end equipment manufacturing, medical equipment and other fields.

VI. Environmental protection and sustainable development

In today's era of environmental protection and sustainable development, sand mold 3D printers also have certain advantages. The traditional sand mold production process will produce a large number of waste and pollutants, such as waste mold materials, chemical reagents, etc., causing greater pressure on the environment. The sand mold 3D printer in the manufacturing process is relatively more environmentally friendly, it is mainly used in sand and other environmentally friendly materials, and can be optimized through the design and printing parameters to reduce the waste of materials. In addition, because 3D printing technology can achieve precision manufacturing, reducing the production of scrap, further reducing the impact on the environment. Therefore, the purchase of sand mold 3D printers is in line with the company's environmental philosophy and social responsibility, and helps the company achieve sustainable development.

To sum up, purchasing sand mold 3D printer has many advantages, including high precision and complex structure manufacturing ability, shorten the production cycle, reduce costs, high design freedom, personalized customization and environmental sustainability. For modern manufacturing enterprises, sand mold 3D printer is not only a kind of advanced production equipment, but also an important tool to enhance the competitiveness of enterprises and realize innovative development and sustainable development. With the continuous progress of technology and the continuous expansion of the application, I believe that the sand mold 3D printer will play an important role in more areas, for the development of the manufacturing industry to bring new opportunities and changes. Therefore, when considering the production upgrade and development strategy of enterprises, the purchase of sand mold 3D printer is a choice worth serious consideration.

Meanwhile, researchers from PetroChina Daqing Chemical Research Center and Lanzhou Chemical Research Center also participated in the communication and interaction of the presentation through video outside the site. 

　　In the report, Dr. Zong Guisheng first analyzed the importance of 3D printing technology from the height of the national manufacturing strategy. He pointed out that in today's escalating global manufacturing challenges, manufacturing is changing faster than ever. In order to be undefeated in the competition, we need to improve efficiency, shorten the time to market, and enhance flexibility, and these needs have driven the development of smart manufacturing. 3D printing, as one of the core technologies of smart manufacturing, has the great potential to change the entire production industry, and is expected to become a key part of China's high-end manufacturing industry, and to promote the upgrading of China's manufacturing industry. At the same time, the global manufacturing countries have introduced their own competitive strategy: the U.S. Obama administration will be 3D printing as a stimulus to the manufacturing industry back to accelerate U.S. economic growth as an important "weapon"; Germany's "Industry 4.0" strategy to support the industrial sector. Germany's "Industry 4.0" strategy supports the research and development and innovation of a new generation of revolutionary technologies in the industrial field; domestically, the "National Additive Manufacturing Industry Development Promotion Plan (2015-2016)" puts forward the initial establishment of a more complete additive manufacturing industry system by 2016, the industry's sales revenue to achieve an average annual growth rate of 30% or more, the aerospace and other direct manufacturing areas to reach the international advanced level and other goals; the "Made in China 2025" plan also includes the following Made in China 2025" plan also made clear the realization of long-term constraints on the development of manufacturing key common technology breakthroughs, to enhance the overall competitiveness of China's manufacturing industry tasks and goals.

　　For the current situation of the 3D printing industry and the development prospects of the Chinese market, Dr. Zong Guisheng pointed out that the current 3D printing industry is growing at an average annual rate of about 30%, desktop 3D printers and the civilian market is growing rapidly, and the growth of services exceeds the growth of equipment. The global market size is expected to exceed $20 billion by 2020. 2013, China's 3D printing market size of 2 billion yuan, and the market potential is huge, it is expected that only sports, recreational products, furniture and other 3D printing direct manufacturing industry annual output value of up to one trillion dollars, the global industry scale will reach one trillion dollars.

　　After that, Dr. Zong Guisheng elaborated on the technical characteristics and application advantages of 3D printing from the perspectives of 3D printing equipment and process respectively. He said that 3D printing technology creates a new ability to produce items of various shapes and sizes, enabling engineers to design more complex products that could not be realized before. 3D printing is widely used in aerospace, automotive manufacturing, casting, medical, due to its advantages of manufacturing complex parts, product diversification without increasing costs, assembly-free, cloud manufacturing, zero-skill manufacturing, portable manufacturing, net molding, Civil and other fields of rapid prototyping, rapid manufacturing. In the future, if the use of 3D printing thinking to design and manufacture products, will bring a new era of design and manufacturing.

　　The National Additive Manufacturing Industry Development Advancement Plan (2015-2016), in particular, puts forward that efforts should be made to break through the special materials for additive manufacturing, and by 2016, the independent production of special materials will be basically realized to meet the needs of industrial development and application. The material and application of 3D printing is also a topic of particular concern to the experts here. In this regard, Dr. Zong Guisheng introduced that the polymer materials used in 3D printing mainly include thermoplastics, photosensitive resins, rubber materials, composite materials, etc., while biomaterials, cellular materials, DNA framework materials, stem cell materials and other materials with great future prospects are also in the research and development stage. Plastic is the most commonly used printing material in the field of 3D printing, and its common types are: ABS plastic, PLA (polylactic acid), nylon, PC, glass-filled polyamine, and through the mixing of different ratios of materials, nearly 120 kinds of soft and hard different new materials can be produced. From the current application of China's 3D printing market, ordinary materials occupy half of the world, domestic self-developed mid-range material products accounted for about 40%, foreign high-quality imported consumables accounted for 10%.
