--Customers do not move to change the design of the warehouse piled up more than 300 sets of scrap molds, checking the accounts found that the mold inventory occupied half a year of profit, which is too painful to taste!

--Customers sent a complex structure of the pieces over, and said that the price is not a problem, an assessment found that the traditional casting process can not be done, looking at such a high value-added orders can only be given up!

Below we help all bosses one by one to sort out clearly, an article to let you fully understand the 3D printing sand casting technology!

What is sand 3D printing?

Sand 3D printing is a relatively new technology, simply put, is like building blocks, with special materials layer by layer "pile" out of the casting sand.

In the past, the traditional method of making sand molds may need to make molds first, and then use the molds to shape, the process is more complicated, and if you want to make some sand molds with very strange and complex shapes, it will be particularly difficult and costly. But sand 3D printing is different, it works with a 3D model in your computer. You input the data of the 3D model of the designed casting into the 3D printer, and the printer will, according to the shape and structure of the model, put special sand or sand-like materials, according to the layer by layer in a precise way and bonded up, just like using countless thin "sand pieces" gradually built into a complete sand mold. In this way, no matter how complex the shape, as long as it can be designed in the computer, it can be printed out, and the speed is quite fast, and do not need to make complex molds like the traditional method, can save a lot of time and cost it.

Principle of Sand 3D Printer

Sand 3D printing is usually done usingBinder Jetting (BJ)The basic principle is as follows:

1. spread sand: The printer spreads a specific casting sand (e.g. silica sand, ceramic sand or coated sand) evenly over the printing platform.
2. spray binder: The spray nozzles precisely spray the binder according to a computer model (CAD data) to bond the sand grains in a specific area.
3. pile up repeatedly: The platform is lowered, sand is spread again and the binder is sprayed, curing and molding layer by layer until the entire sand print is completed.
4. reprocess: Remove unbonded loose sand, harden and clean the printed sand model, which can then be used for metal casting.

What are the core problems addressed by 3D printed sand casting?

The existence or birth of each technology must have its "mission". Commonly known as a solution to a particular problem, to meet market demand, this is the value of its existence. Below we take a look at the sand 3D printing technology to solve the thorny problems encountered in the traditional casting, as follows:

• Manufacture of complex shaped partsTraditional sand casting to manufacture complex shapes is difficult and costly, such as aviation engine blades inside the fine cooling channels, traditional processes are difficult to accurately mold. 3D printing sand based on digital models, can easily turn complex shapes into reality, from the dense concave, raised automotive engine block sand, to have a subtle biomimetic structure of the shell of the medical device sand, can be perfectly rendered.
• long production lead timeTraditional sand casting need to go through a long process of designing molds, manufacturing molds, debugging molds, large-scale mold manufacturing cycle often exceeds a few months. 3D printing sand without mold production, directly according to the digital model printing, design modification is only required to operate the model on the computer, reprinting can be, can significantly shorten the production cycle. Such as research and development of new automotive engine block, the traditional casting mold scrap remake at least two weeks, 3D printing sand can be completed on the day of the new model printing, the next day can be put into casting.
• Difficulty in cost controlTraditional casting mold manufacturing material waste is serious, the utilization rate of complex mold materials is less than 30%, and high labor costs. 3D printing sand on-demand printing, accurate sand, material utilization rate of more than 90%, reduce waste. High degree of automation of the printing process can reduce labor costs. Take a small foundry as an example, with an annual production capacity of 5,000 pieces of small pipe fittings castings, after the introduction of 3D printed sand, the material cost will be reduced by 150,000 yuan per year, and the labor cost will be cut by 200,000 yuan.
• Low precision of castingsThe traditional sand mold due to mold wear, parting surface fitting error, casting size deviation often exceeds ±1mm, subsequent machining allowance, material waste, and prone to local loosening, sand entrapment and other defects, resulting in uneven mechanical properties of the casting. 3D printing of the sand model by the digital model of the precise drive, sand size accuracy of up to ±0.5mm, can achieve uniform compactness, to avoid uneven sand loose, and at the same time optimize the solidification process to significantly reduce shrinkage holes, shrinkage, to ensure reliable internal quality of the casting. At the same time, the solidification process is optimized, greatly reducing shrinkage holes and shrinkage loosening, and ensuring stable and reliable internal quality of castings.
• High environmental pressureTraditional casting mold manufacturing produces a large amount of waste metal, waste plastic, sand processing waste sand piles up. 3D printing sand production, unused sand can be recycled and reuse, very little waste, and the printing process does not require a large number of chemical binders, reducing the emission of hazardous gases, and improve the workshop environment. According to statistics, after the adoption of 3D printing sand mold, the casting workshop waste emissions reduced by more than 80%, dust, harmful gas concentration of environmental standards.

How does a foundry evaluate if they need to buy a sand 3d printer?

The price of a sand 3D printer is not cheap (usually the larger the size the more expensive), to buy is relatively cautious, especially small and medium-sized foundries. In order to help bosses to assess whether there is a need to buy, we have specially organized the following some evaluation points, to give the boss of the traditional foundry a reference, and then according to their own situation to decide whether to buy:

production requirement

• Product complexity: If the foundry often produces complex shapes, castings with fine structure or internal channels, such as aero-engine blades, automobile cylinder blocks, etc., the traditional process is difficult to meet the requirements, sand 3D printer can play an advantage.
• Production size and lot size: For small-volume, multi-variety casting production, sand 3D printers offer the flexibility to quickly switch products without the need to make molds, reducing costs and cycle time. However, for large-scale, single-species castings, traditional processes may be more cost-effective.
• Delivery period requirementsThe sand 3D printers allow for shorter lead times and quicker order response if the customer has stringent lead times.

cost-effectiveness

• Investment in equipmentThe cost of purchasing a sand 3D printer, installation and commissioning costs, and maintenance costs need to be taken into account.
• running cost: Includes printing materials, energy consumption, and labor costs. Compare with the traditional casting process and analyze the high and low long-term running costs.
• potential gainConsider the potential benefits of using sand 3D printers in terms of improved product quality, shorter cycle times, and lower scrap rates.

technical capability

• Employee Skills: Evaluate how well your current employees know 3D printing technology and whether you need to train or recruit specialized talent.
• Technical Support: To understand the technical support capability of the equipment supplier, including whether the services such as installation and commissioning, training and fault repair are timely and effective.

market competition

• Industry Trends: Keep an eye on your peers to see if they are already adopting sand 3D printing, and if competitors are already using it and gaining an advantage, foundries may need to consider purchasing it in order to remain competitive.
• client needThe purchase of sand 3D printers can help to meet the needs of customers who want to see foundries adopting advanced technologies to improve product quality and productivity, as well as to increase their competitiveness in the marketplace.

environmental requirement

• If the local environmental protection requirements are strict, the traditional casting process is under great pressure in terms of waste sand treatment and exhaust gas emission, etc., sand 3D printers can help enterprises meet the environmental protection requirements due to the advantages of high material utilization rate and low waste.

What kind of talent is needed for sand 3D printing?

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.
