After experiencing soaring costs and supply chain shocks, the global foundry industry is standing at a critical crossroads. The asset-heavy, long-cycle nature of the traditional model has become a heavy shackle to cope with the rapid iteration of the market. And(binder jetting) The maturity of the technology, is "no mold casting" from the laboratory concept to the forefront of large-scale production, a digitally driven process revolution has quietly come. For the foundry is still watching, 2024 to 2026 will be a strategic window to determine the competitiveness of the next decade.
Quick Answer. Sand 3D Printing Market to Accelerate Expansion on the Back of Digitalization & Flexible Manufacturing Demand by 2026. The technology is utilized throughMoldless moldingIt has shortened the development cycle of complex castings from months to weeks and reduced the cost by up to 70%, and is becoming the core solution for rapid prototyping and low-volume production in aerospace, high-end automotive and other fields.
1. Shortened product life cycle: Especially in the automotive and high-end equipment fields, the product iteration speed has been shortened from 5-7 years in the past to 2-3 years. Traditional mold development (time-consuming)3-4 monthsCost1-2 million dollars) has become unbearable.
2. Demand for customization and lightweighting explodes: integrated die casting for new energy vehicles, complex inner runner components for aerospace, and unique shapes for works of art, these designs are important to theInternal cavities, thin-walled, shaped cooling channelsThe realization of this is extremely demanding and can hardly be economically accomplished by conventional mold making methods.
3. Supply chain resilience requirements: Geopolitical and cost pressures are driving manufacturers to seek shorter, more controllable localized supply chains. Digital, local production capabilities that can respond quickly to design changes and do not need to rely on offshore tooling processing are particularly valuable.
Sand 3D printing, especiallyBinder Jetting TechnologyThis is the "scalpel" solution to these challenges. It is not simply a replacement for manual modeling, but rather a fundamentalReorganized production processes::
* Process Comparison::
| annular ring | Traditional Casting Process | Digitalization process based on sand 3D printing |
|---|---|---|
| Core path | 3D design → open metal/wood mold → molding (hand/machine) → casting in box | 3D design → direct printing of sand mold/core → casting in box |
| time cycle | Weeks to months | Days to 2 weeks (for the first one) |
| Modification costs | Modifying or re-molding can be costly | Modify CAD models at near-zero marginal cost |

Demand is centered onHigh temperature alloys, titanium alloysof difficult-to-process materials such asSingle piece, small lotComplex components such as engine blades, magazines, satellite mounts. For precision (usually required)±0.3mm(within) and sand strength requirements are extremely high. Leading domestic companies such asLongyuan Forming (Longyuan AFS) Relying on its nearly 30 years of experience in industrial-grade printing, it has accumulated a large number of successful cases in this field.
* Automobiles (especially new energy and premium brands): The core drivers areRapid prototyping and lightweightingThe test is conducted on the basis of the following characteristics. Used for prototype verification and small batch production of engine block cylinder head, gearbox housing, battery box bracket, etc., which can advance the cycle time of bench test.2-3 months. For example, using the3DPTEK-J SeriesThe sand pattern printed by the equipment has been widely used in the R&D centers of many domestic mainstream automobile enterprises, helping them to reduce the development cost of single-wheel samples.70% Above.
* Pumps, valves and heavy machinery: The needs areShorten lead times and respond to customized orders. Large, complex pump bodies and valve bodies usually require large equipment. For example, molding sizes up to2500×1500×1000mm(used form a nominal expression)3DPTEK-J2500The model is capable of integrally printing large pump casing sand molds, avoiding cumbersome block production and assembly, and significantly improving the delivery reliability of large castings.


* Artwork and Cultural Creation Casting: The core of the demand isRealization of the artist's arbitrary creativityThe digital sculpture is free from the need to rely on skilled mold makers. Digital sculptures can be converted directly into sand molds, perfectly reproducing complex textures and organic forms.

* Value for money becomes the dominant decision-making factor: As domestic equipment manufacturers make breakthroughs in core components (e.g., printhead control, software algorithms) withHigh stability, open system, localized serviceThe market share of domestic brands will continue to expand, providing users with a shorter return on investment cycle than traditional imported equipment.
reach a verdict: This is no longer the time to discuss the "need" for sand 3D printing, it is the time to discuss the "need" for sand 3D printing.How to choose the right path to upgrade2024-2026 is the key investment period for enterprises to build digital casting capability and seize the high ground in the future market. The cost of waiting will be much higher than the risk of early layout.
Having understood the market trends and the inevitability of the transition, the next key step is to cut through the marketing jargon and assess the true capabilities of the equipment from an engineering perspective. Selecting a杏彩体育网:Sand 3D Printer, essentially choosing a set ofDigital Production SystemIts performance can never be summarized by a single parameter. Its performance can never be summarized by a single parameter, but is defined by the following five interrelated core indicators. Our analysis is based on long-term field tests and production data.
This is the primary indicator of whether a casting is "usable" rather than "castable". A distinction must be madePrinting Accuracytogether withFinal casting accuracyThe
Analysis of Sand Printing Accuracy::
Dimensional tolerances: Usually expressed as "±0.3mm (≤300mm)". This refers toThe sand itselfdimensional deviations in a controlled environment. For example杏彩体育网:3DPTEK-J1800In the technical solution, this accuracy is achieved by high precision linear motors with a closed-loop control system. It is important to note that tolerances are relaxed as the size increases, and machines with proportional representations (e.g., 0.1%) are more favorable for larger parts.
Minimum Wall Thickness/Feature Size: This directly determines the ability of the machine to print complex thin-walled sand cores or fine runners. This capability is determined by thePrinthead Resolution (DPI) cap (a poem)Thickness of sand layerA 400 DPI printhead in conjunction with a layer thickness of 0.25-0.3mm will typically achieve a3-5mmThe stabilized minimum wall thickness of the
surface roughness: The roughness of the sand surface (Ra value) directly affects the difficulty of sand cleaning and surface finish of castings. It is mainly determined by sand grain size (e.g. 100/200 mesh is finer than 70/140 mesh) and binder penetration control technology. The uniform surface of the sand mold printed by excellent equipment can reach about Ra 12.5μm, which provides a good substrate for subsequent application of refractory coatings.
Effects on castings and measurements::
Chain of loss of precision: Sand mold accuracy → (coating layer thickness error) → (metal solidification shrinkage) → casting accuracy. Therefore, a high-precision sand mold is the key to high-quality castings.necessary but insufficient condition (math.)The
standard of measurement: must be used3D scannermaybeLarge-scale Coordinate Measuring Machine (CMM) Critical positioning dimensions and wall thicknesses of the printed sand pattern are inspected and compared to the original CAD model to generate a chromatographic deviation report. Caliper measurements alone cannot be fully evaluated.
Selection Strategy Matrix::
| production requirement | Recommended Build Box Sizing Strategies | Core considerations |
|---|---|---|
| Large single castings (e.g. machine tool bases, large pump housings) | Select a size equal to or slightly larger than the maximum contour of the part. For example, to produce a pump body of about 2 meters, a machine such as the 3DPTEK-J2500 (2500 x 1500 x 1000 mm) should be considered. | Ensure one-time integral molding, avoiding the loss of precision and strength risk caused by segmented splicing. |
| Small batch, multi-variety (e.g. engine trial, multiple valve bodies) | Select a medium-sized build box (e.g., 1000-1800mm long side) and utilize the height direction (Z-axis) for nested multi-part printing. | Maximizes the number of parts printed in a single pass, diluting the cost and time of printing a single sand pattern. Maximum equipment utilization. |
| Mix of oversized and regular sizes | Consider "one large, one small" or "one medium, one large" equipment combinations. | Optimize your investment portfolio by using small machines to cope with fast-turnaround R&D parts and large machines to safeguard the capacity of large parts. |
Key Insights: The build box'seffective utilizationMore important than nominal size. The internal structure of the device needs to be evaluated for ease of automated multi-part nesting and the intelligence of the software nesting algorithms.
Mainstream material properties and equipment suitability::
Binder compatibility::
Vendors often advertise "XX seconds/layer", but the disengagement of thelayer thicknesscap (a poem)Build Box UtilizationTalking about speed is meaningless. Real capacity should be measured in terms ofLiters per hour (L/h) maybeKilograms per hour (kg/h) (used form a nominal expression)Effective molding volume rateto measure.
Parameter depth correlation::
* layer thickness: Increasing the layer thickness (e.g. from 0.25mm to 0.35mm) significantly reduces the total number of layers and shortens the print time, but at the expense of Z-axis accuracy and surface step effects. Superior equipment allows the0.2-0.5mmFlexible adjustment to part requirements within the range.
* Sand spreading and jetting speedBoth must be optimized in tandem. High-speed sanding needs to be matched to a high-speed scanning printhead system, otherwise it can become a bottleneck. For example, the use of parallel scanning with multiple printheads (such as the3DPTEK-J4000(using 16 nozzles) is the fundamental way to increase speed.
Real Capacity Calculation::
`Capacity per day ≈ build box volume × fill rate × (24 hours / total time for single box printing and preparation)`
Fill rate is dependent on part nesting density, while "total time" includes printing, sanding, sand preparation, etc. Highly automated machines (with automatic sand cleaning stations, alternating dual cylinders) can minimize non-printing time, thus improving overall equipment effectiveness (OEE).
This is the metric that is most easily overlooked by parameter tables, yet determines long-term operational success or failure. Reliability is reflected inMean Time Between Failure (MTBF) cap (a poem)Critical component lifeUp.

Assessment methodology::
reach a verdict: Evaluation of onemachine, it is important to use these five indicators as atotal systemThe trade-off. High accuracy can come at the expense of speed, and fully enclosed material systems are stable at the expense of cost control. For foundries looking for long-term competitiveness and return on investment, choosing a machine in theAccuracy, efficiency, material openness, reliabilityEquipment with an optimal engineering balance between the two, and with a sufficiently localized service case, is the first step towards success in digital casting.

Concluding insights::
International brands and domestic brands are not simply "substitutes", but form a differentiated market stratification. For the pursuit of the world's top process verification, budget and strict requirements of the brand enterprise, international brands are still a reliable choice. However, for the vast majority of Chinese foundry enterprises, the core needs areStable, efficient, autonomous and controllable digital production capacity at an affordable cost. in order to3DPTEKThe national brands represented by theOpen system, in-depth localization services, proven reliability in mass production, and significant price/performance advantagesThe company has become the mainstream choice in the market and is redefining the value standard of industrial-grade sand 3D printing. Choosing a national brand is not only a cost consideration, but also a strategic partner who understands the pain points of Chinese manufacturing and can grow together with the enterprise.
After the technical parameters have been compared and the brand analyzed, a pragmatic manager must look at the financial aspect.Sand 3D PrinterThe investment decision should never be based on equipment quotations alone. It is a systematic investment whose true cost is determined by theInitial capital expenditure (CAPEX)cap (a poem)Ongoing operating expenses (OPEX)Together. Neglecting any one of these components can nullify the expected return on investment (ROI). This section will provide you with a complete framework for financial analysis.
Device Ontology and Core Configuration: i.e. the price of the printer mainframe. Need to clarify whether the offer includes standard configuration (such as a certain number of printheads, basic software licenses).
Installation, commissioning and basic training feesThe price of the equipment is typically 21 TP3T-51 TP3T, which includes machine set-up, leveling, electromechanical connections, commissioning of basic process parameters and initial operator training.draw attention to sth.: choose something like3DPTEKThese types of brands with multiple service centers across the country can effectively reduce the additional installation costs associated with remote travel.
Essential "post-processing equipment" investment (often underestimated)::
| aftertreatment | Necessary Equipment / Workstations | Functionality and cost implications |
|---|---|---|
| clear sand | Dedicated desanding station / Negative pressure desanding room | Remove unbonded loose sand from molded parts. Manual desanding is extremely inefficient and dusty. An automated desanding station, such as the model with the 3DPTEK-J2500, is a key investment for continuous productivity and occupational health. |
| Curing / Drying | Oven or curing station | Post-curing is essential for processes using certain resin systems or where the strength of the sand mold needs to be increased. The machine must be sized to match the maximum print pattern. |
| Sand Coating | Paint mixing and painting station | Applying refractory coatings to sand molds is a critical step in obtaining a quality casting surface. Investment in paint mixing equipment and a drying site is required. |
| Sand handling and recycling | Sand sifter, sand temperature regulator | Screening, cooling and reusing recycled sand directly affects material costs and print quality. For large-scale continuous production, this is a necessary investment. |
Initial stock of consumables: In order to start production, an initial stock of molding sand (e.g. silica sand, pozzolanic sand) and binder (furan/phenolic resin) needs to be purchased. For a medium-sized machine, for example, the first stock of sand usually requires 10-20 tons and a few hundred kilograms of resin.
Cost of consumables (variable cost body)::
Energy and indirect costs::
To assess ROI, it is necessary to quantify the technology that bringsRevenue enhancementtogether withCost savings. The following is a practical framework for measurement modeling:
Core Benefits and Savings Items:
Simple Measurement Modeling of the Payback Cycle:
`Static payback period (years) = total investment (CAPEX) / annualized incremental net income'Incremental annualized net income = (Annual tooling cost savings + development cycle reduction benefits + labor/material savings) - Annual OPEX additions
Typical Case Reference: Based on3DPTEKStatistics on its service-based manufacturing business and customer cases show that a scenario focused on complex part prototyping and low-volume production can typically reduce the cost of single-part sub-development through its equipment and process70% and aboveThe overall payback period can be controlled at 18-36 months Inside. The payback period may be shorter for users who use it directly in the production of high value-added parts.
Key Tips: The most accurate ROI analysis should be based on your own 1-2Typical ProductsPerform simulation measurements. It is recommended that during the selection phase, suppliers (e.g., the3DPTEK) offers parts specific to yourProcess Solution and Cost Analysis ReportThis will make the financial projections incredibly clear.
reach a verdict: Procurementmachine, essentially buying a set of "time compressor"and"Complexity decoupler". The financial value is reflected not only in the explicit cost savings, but also in the strategic gains made by accelerating innovation and taking on high value-added orders. Building a complete financial model as described above is the final, and most important, step in making rational, confident investment decisions.
Do not blindly pursue the "state of the art". The first step should be to conduct an internal process audit to quantify the gap between the current situation and the target.

Core revelationsTogether, these three cross-cutting examples show that the successful application of sand 3D printing has gone beyond the initial stage of "replacing molds". It is becomingDriving product innovation (e.g., Case 1's follow-the-shape waterways), reconfiguring production models (e.g., Case 2's small batch economics), and passing on cultural heritage (e.g., Case 3's digital rebirth) strategic technologies. By investing in this, we are investing in the core flexible capacity and innovation base to cope with the uncertainties of the future.
Q1: An industrial grade杏彩体育网:Sand 3D PrinterWhat is the price range? What is the price difference between domestic and imported equipment?
A. The price range is enormous, depending on size, precision and automation. Take, for example, the mainstream demand in the domestic market:
* Domestic equipmentAs3DPTEKof the J series, the entry-level investment for a medium-sized machine (molding dimensions of approximately 1800 x 1000 x 700 mm) is usually in the range ofRMB 1,500,000 to 3,000,000Range. Larger units (e.g. J2500/J4000) are in the higher price range.
* Imported high-end equipment: The price of the same level of equipment can be as high as the price of domestic equipment. 1.5x to more than 3xSome of the ultra-large or customized systems can be in the tens of millions of dollars range.
The core of the differenceIt's not just in the brand premium, it's in the reflection:
1. Material Systems Strategy: Imported equipment is mostly closed or semi-closed systems bound to specialized consumables, while domestic open systems (such as those used by 3DPTEK) allow for the use of better-cost third-party materials, with significant differences in long-term operating costs.
2. Integrated Solution Maturity: Imported brands dominate the globalized high-end case base; domestic brands areLocalized process adaptation, service responsiveness and cost effectivenessA decisive advantage has been constructed. For the vast majority of Chinese companies looking for a clear return on investment, the comprehensive cost advantage of domestic equipment generally shortens the payback period. 30%-50%The
Q2: What 'post-processing equipment' do I need to invest in besides the printer itself? What is the total cost share?
A. Post-processing is the key to guaranteeing production continuity and improving the quality of sand molds, and its investment is often underestimated, and may account for as much as 20%-40%. Required sessions include:
| aftertreatment | Core Equipment / Workstations | Function and necessity | Estimated cost share |
|---|---|---|---|
| Automated sand cleaning | Negative pressure sand cleaning station, vibrating screening system | Efficient removal of loose sand, safeguarding occupational health and continuous production. Manual sand removal is not practical for large sand molds. | High (10%-20%) |
| Sand strengthening and drying | Hot Air / Microwave Curing Oven | Depending on the resin system used, improving the final strength and stability of the sand mold is a key step in ensuring the success of the casting. | Medium (5%-10%) |
| Sand handling and recycling | Sand sifter, sand temperature regulator, sand mixer | Screening, cooling and performance restoration of recycled sand directly affects material cost and print layer quality. | Medium to High (8%-15%) |

Key recommendations: When planning budgets, equipment vendors should be asked (e.g.3DPTEK) Provide the host computer with its matchingTotal solution and quotation for reprocessing unit, avoiding passive additional investment at a later stage.
Q3: What is the strength of sand molds with Binder Jetting technology? Can it meet the requirements of all casting metals?
A. Modern binder jetting technology has been able to produce sand molds that meet the strength requirements of most casting scenarios.
* Typical intensity data: With furan or phenolic resins, the tensile strength of printed sand forms is typically up to 1.5 - 2.5 MPa, higher flexural strength, which is enough to cope with:
* :: Casting of light metals such as aluminum alloys and magnesium alloys.
* :: Cast iron (gray, ductile) and plain cast steel.
* Most stainless steels and high temperature alloys.
* Extreme condition verification: For extreme conditions (e.g., oversized castings weighing several tons, pours with very high hydrostatic head), the strength of the sand mold is not the only consideration, but needs to be evaluated in a comprehensive manner.Sand dispersibility, outgassing (typically <12 ml/g) and thermal stability.. This needs to be done byProcess validationto determine. Leading domestic suppliers such asLongyuan Forming (Longyuan AFS)With its experience in operating foundries, the company is able to offer its customers a package of proven process parameters for specific materials (e.g. high chrome steels, high temperature alloys).
Q4: What are the main challenges and costs of daily operation and maintenance of equipment? How to control it?
A. The main challenge is to maintain long-term system stability with controllable consumable costs.
* Core challenges::
1. Print Head Maintenance: Preventing nozzle clogging is a top priority. Choose a spray nozzle that hasBuilt-in circular filtration, constant pressure ink supply and automatic cleaning functiondevices (such as the 3DPTEK-J series design) can greatly reduce this risk.
2. Sand management: Particle size distribution, temperature and humidity control of recycled sand directly affects the quality of laid powder. A standardized sand handling process needs to be established.
* Cost components and control::
* Cost of consumables (approx. OPEX 60%-70%): Sand and resin are the biggest expenses.Selection of equipment for open material systemsIt is the most effective means of controlling costs, and it allows you to source the most cost-effective compliant materials from the competitive marketplace.
* Critical component replacement (e.g. print head): Industrial printheads are consumables with a life span of approximately 1-2 years. This needs to be set aside in the annual budget. Quality equipment design can extend their life.
* Energy and Maintenance: Electricity, compressed air consumption and annual maintenance contracts (AMC) are fixed expenses. Choosing energy-efficient and reliable equipment reduces these costs at the source.
Q5: What are the most overlooked key contract terms during procurement negotiations?
A. In addition to price and delivery, the following technical terms are crucial but often overlooked:
1. Performance guarantee clauses with clear acceptance criteria: Contracts must be accompanied by technical annexes.quantizeAccuracy (e.g. ± 0.3mm), strength (e.g. tensile strength ≥ 1.8MPa) and other key indicators, and write down theTest methods, tools and remedies for failure to meet standards (e.g., repair, replacement or refund)Avoid vague expressions such as "industry-leading". Avoid vague expressions such as "industry-leading".
2. Attribution of Software and Intellectual Property: Explicit agreement:
* :: Upgrade policy for operating software, process control software (is there a charge inside or outside the warranty period?). .
* :: Materials specific to your business that are generated in the course of collaborative commissioning.Database of optimized process parametersThe intellectual property rights are attributed and used.
3. Quantified after-sales service level agreements (SLAs): Instead of just saying "provide timely services", it should be clear:
* response time: Specific timeframes for telephone support (e.g., within 2 hours), remote diagnosis (e.g., within 4 hours), and on-site arrival of an engineer (e.g., within 48 hours of a serious failure).
* Spare parts supply time: Maximum time for stocking and delivery of commonly used spare parts and critical components (e.g. printheads).
* On-site support staff qualifications: Requirement to send engineers with extensive backgrounds in casting processes, rather than maintenance personnel with only mechanical knowledge.
