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打印？

砂型3D打印是一種比較新的技術(shù)，簡(jiǎn)單來(lái)說(shuō)，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(guò)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(huì)特別困難，成本也高。但砂型 3D 打印就不一樣了，它是通過(guò)電腦里的三維模型來(lái)工作的。你把設(shè)計(jì)好的鑄件三維模型數(shù)據(jù)輸入到 3D 打印機(jī)里，打印機(jī)就會(huì)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(zhǔn)地鋪放和粘結(jié)起來(lái)，就像用無(wú)數(shù)個(gè)很薄的 “沙片” 逐漸搭建成一個(gè)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(jì)出來(lái)，它都能打印出來(lái)，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(shí)間和成本呢。

砂型3D打印機(jī)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(jī)在打印平臺(tái)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(jì)算機(jī)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(tái)下降，再次鋪砂并噴射粘結(jié)劑，逐層固化成型，直至整個(gè)砂型打印完成。
4. 后處理：去除未粘結(jié)的松散砂料，對(duì)打印出的砂型進(jìn)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(wèn)題？

每一項(xiàng)技術(shù)的存在或誕生必定是有它的“使命”。通俗來(lái)說(shuō)就是解決了特定問(wèn)題，滿足了市場(chǎng)需求，這就是它存在的價(jià)值。下邊我們來(lái)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(wèn)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(dòng)機(jī)葉片內(nèi)部精細(xì)冷卻通道，傳統(tǒng)工藝難以精準(zhǔn)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(shí)，從帶有密集內(nèi)凹、凸起的汽車發(fā)動(dòng)機(jī)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(jì)模具、制造模具、調(diào)試模具等冗長(zhǎng)流程，大型模具制造周期常超數(shù)月。3D 打印砂型無(wú)需模具制作，直接按數(shù)字模型打印，設(shè)計(jì)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(dòng)機(jī)缸體時(shí)，傳統(tǒng)鑄造模具報(bào)廢重制至少兩周，3D 打印砂型當(dāng)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(fèi)嚴(yán)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(zhǔn)用砂，材料利用率超 90%，減少浪費(fèi)。打印過(guò)程自動(dòng)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(wàn)元，人工成本削減 20 萬(wàn)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(jī)加工余量多、材料浪費(fèi)大，且易出現(xiàn)局部疏松、夾砂等缺陷，導(dǎo)致鑄件力學(xué)性能不均。3D 打印砂型由數(shù)字化模型精準(zhǔn)驅(qū)動(dòng)，砂型尺寸精度可達(dá) ±0.5mm 以內(nèi)，能實(shí)現(xiàn)均勻緊實(shí)，避免砂粒松散不均，同時(shí)優(yōu)化凝固過(guò)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(guò)程無(wú)需大量化學(xué)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(jì)，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(dá)環(huán)保標(biāo)準(zhǔn)。

鑄造廠如何評(píng)估是不是需要買砂型3d打印機(jī)？

一臺(tái)砂型3D打印機(jī)的價(jià)格不便宜（通常來(lái)說(shuō)尺寸越大越貴），要購(gòu)買的話相對(duì)是比較謹(jǐn)慎的，特別是中小型鑄造廠。為了幫助老板們?cè)u(píng)估一下是否有購(gòu)買的必要，我們特地整理出了下邊的一些評(píng)估要點(diǎn)，給傳統(tǒng)鑄造廠的老板們一個(gè)參考，然后根據(jù)自己的情況來(lái)決定要不要購(gòu)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(xì)結(jié)構(gòu)或內(nèi)部通道的鑄件，如航空發(fā)動(dòng)機(jī)葉片、汽車缸體等，傳統(tǒng)工藝難以滿足要求，砂型3D打印機(jī)能發(fā)揮優(yōu)勢(shì)。
• 生產(chǎn)規(guī)模與批量：對(duì)于小批量、多品種的鑄件生產(chǎn)，砂型 3D 打印機(jī)可靈活快速切換產(chǎn)品，無(wú)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(duì)交貨期要求嚴(yán)格，砂型 3D 打印機(jī)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(jī)的購(gòu)買成本、安裝調(diào)試費(fèi)用及后期維護(hù)成本。
• 運(yùn)行成本：包括打印材料、能源消耗、人工成本等。對(duì)比傳統(tǒng)鑄造工藝，分析長(zhǎng)期運(yùn)行成本的高低。
• 潛在收益：考慮使用砂型 3D 打印機(jī)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(lái)的潛在收益。

技術(shù)能力

• 員工技能：評(píng)估現(xiàn)有員工對(duì) 3D 打印技術(shù)的掌握程度，是否需要培訓(xùn)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(xùn)、故障維修等服務(wù)是否及時(shí)有效。

市場(chǎng)競(jìng)爭(zhēng)

• 行業(yè)趨勢(shì)：關(guān)注同行是否已采用砂型 3D 打印技術(shù)，若競(jìng)爭(zhēng)對(duì)手已應(yīng)用并獲得優(yōu)勢(shì)，為保持競(jìng)爭(zhēng)力，鑄造廠可能需要考慮購(gòu)買。
• 客戶需求：了解客戶對(duì)產(chǎn)品的新要求和期望，若客戶希望看到鑄造廠采用先進(jìn)技術(shù)提升產(chǎn)品質(zhì)量和生產(chǎn)效率，購(gòu)買砂型 3D 打印機(jī)有助于滿足客戶需求，提高市場(chǎng)競(jìng)爭(zhēng)力。

環(huán)保要求

• 如果當(dāng)?shù)丨h(huán)保要求嚴(yán)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(jī)因材料利用率高、廢棄物少等優(yōu)勢(shì)，有助于企業(yè)滿足環(huán)保要求。

1. Addressing the limitations of traditional casting processes

Difficulty in molding complex structures 

Conventional casting processes often face enormous technical difficulties and high costs when manufacturing sand molds of complex shapes. For example, aircraft engine blades usually have fine and complex cooling channels inside, the traditional process of manufacturing such molds is extremely difficult. The sand 3D printer through digital modeling and layer-by-layer printing technology, can easily achieve the manufacture of complex shapes of sand molds, greatly reducing the technical threshold and cost.

Customized production is limited 

With the rise of personalized consumption and niche markets, the demand for small-lot, customized castings is growing explosively. However, the traditional casting process, with its high mold opening costs and long customization cycle, is difficult to meet the market's rapid response needs. Sand 3D printers do not require molds and are able to quickly design and print sand molds according to customers' special specifications, shapes and performance requirements, greatly improving the flexibility and efficiency of customized production.

2. Enhancing production efficiency and cost control

long production lead time

Traditional sand casting requires a lengthy process of designing the mold, manufacturing the mold, commissioning the mold, etc. The manufacturing cycle for large molds often exceeds several months. During the period may also be due to design changes or mold defects lead to rework, further extending the production cycle. Sand 3D printers do not need to make molds, directly according to the digital model printing, can significantly shorten the product development cycle, improve production efficiency.

Difficulty in cost control

In the traditional casting mold manufacturing process, the material waste is serious, and the material utilization rate of complex molds is less than 30%.

Why is it called a sandbox-less 3D printer?

The boxless 3D printer is so named because it eliminates the use of a traditional box in the sand 3D printing process, significantly differentiating it from conventional sand 3D printers. Here's more about it from a variety of perspectives:

The role and limitations of traditional sandboxesSandboxes are an indispensable part of the traditional sand casting process and some traditional sand 3D printing techniques. It is used to hold the sand, provide molding space for the sand model, ensure that the sand maintains a specific shape during the molding process, and ensure the integrity of the sand model during transportation and box closing. However, the fixed size of the sand box limits the size of the sand mold that can be produced, and the production and maintenance costs are high. For the complex structure of the sand mold, the sand box is difficult to design and manufacture, and it may also affect the heat dissipation and air permeability of the sand mold, which may affect the quality of the castings.

How sandless box 3D printers work: The sandbox-less 3D printer adopts sandbox-less flexible area molding technology, in which abrasive and binder are stacked and molded layer by layer by the nozzle directly on the worktable. The equipment has a precise sand spreading system, which can evenly spread the sand material in the printing area, and the nozzle accurately sprays the binder according to the model cross-section information, so that the sand particles are bonded to form the sand shape layer by layer. In this process, there is no need for a sand box to provide molding space and constraints, which greatly improves printing flexibility and freedom.

Basis of namingThe naming of the 3D printer directly reflects its core technical feature, which is that it is free from the constraints of the traditional sand box, creating a new mode of sand 3D printing. This naming scheme is simple and clear, highlighting the essential difference with the traditional sand 3D printing equipment, and emphasizing its unique advantage of realizing high-precision and high-efficiency manufacturing of sand patterns without the assistance of a sand box during the printing process.

Sandless Box 3D Printer vs. Traditional Sand 3D Printer

There is a clear difference between the working principle of a boxless 3D printer and that of a traditional sand 3D printer. Traditional sand 3D printers rely on a fixed sand box to define the molding space, and rely on the sand box to provide partial support, and the print path is limited by the sand box; while sand box 3D printers use flexible area molding technology, expanding the printing platform on demand, breaking through the size limitations, and supplying the sand and binder with greater precision, and adjusting the internal sand buildup and binder injection to provide support, so the print path is more freely and flexibly planned, and it can effectively improve the printing efficiency and sand quality. It can effectively improve the printing efficiency and the quality of the sand mold.

Prospects for sandbox-less 3D printers in the foundry sector

Significant cost advantages

On the one hand, the cost of ownership is reduced, as the price of 4-meter and larger boxless 3D printers is comparable to that of 2.5-meter machines, allowing companies to obtain larger sizes of abrasive molds at a lower cost per unit. On the other hand, material waste is reduced, as boxless 3D printers allow precise use of materials such as sand and binder, reducing production costs.

Strong growth in market demand

Aerospace, automotive, energy power and other fields of large, complex, high-precision castings demand continues to rise. For example, the manufacture of aircraft engine components, automotive engine block, etc., sandless 3D printers can meet the high-performance requirements for castings in these fields, the market potential is huge.

Significant increase in design freedom

The sandless box 3D printer can manufacture complex geometric shapes and cavities that are difficult to achieve by traditional methods, realizing parts integration and lightweight design, providing more space for product innovation and helping to improve product performance, reduce costs and enhance the market competitiveness of enterprises.

Significant increase in productivity

Compared to traditional mold making methods, sandbox-less 3D printing of sand molds or cores takes only a few hours to a few days, dramatically shortening the development and production cycle of new products, helping manufacturers respond faster to changes in market demand, and improving productivity and economic efficiency.

Superior environmental performance

Sandless 3D printers use materials on demand, reducing waste and disposal costs of leftover materials, and some of the equipment can use environmentally friendly materials and binders, which reduces environmental pollution, meets the requirements of sustainable development, and helps foundry companies to meet the increasingly stringent restrictions of environmental regulations.

Deepening Industrial Integration

The integration of sand box 3D printer and foundry is deepening, enterprises through mergers and acquisitions of foundries and other ways to open up the "3D printing + casting" process, to provide the whole industry chain overall solution, and promote the foundry industry to the green, intelligent, high-end direction of development.
