How to control sand 3D printing costs to save money?

May 31, 2024

With the sand 3D printer in the foundry industry is more and more recognised, the application is more and more popular, the production cost has become more and more concerned about the problem.

Controlling the cost of sand 3D printing is key to ensuring a cost-effective and sustainable project. Here are some effective strategies that can help you save money during the sand 3D printing process:

Optimise material usage

Precisely Calculate Material Requirements: use a software tool to accurately calculate the amount of sand and binder needed before you start printing. This helps you avoid material waste.

Material recycling: Recycle and reuse unused sand as much as possible. Many 3D printers allow the recycling of uncured sand, which can significantly reduce material costs.

Choosing the right materials: Choose the most appropriate sand and binder for your specific application. Different materials have different costs and properties, and choosing the right material for your project needs can optimise cost-effectiveness.

Design Optimisation

Lightweight design: Reduce material usage through topology optimisation and lightweight design. Optimise the part structure using Computer Aided Design (CAD) software to remove unnecessary materials.

Reduction of support structures: Optimise the design to reduce or eliminate the need for support structures. This not only saves material, but also reduces post-processing effort and costs.

Modular design: Complex parts are designed as detachable modules for easy printing and assembly. This improves printing efficiency and material utilisation.

Improve printing efficiency

Batch production: Try to produce as many parts as possible in a single print run to increase printer utilisation and productivity. Batch production dilutes the fixed cost of each part.

Optimise Printing Parameters: Adjust printing parameters such as layer thickness, print speed and binder dosage to find the best print settings for both quality and cost savings.

Regular maintenance: Regularly check and maintain 3D printers to ensure that they are running at their optimal condition and avoid material wastage and production interruptions due to equipment failure.

Energy Management.

Use energy-efficient equipment: Select energy-efficient 3D printers and post-processing equipment to reduce energy consumption and running costs.

Optimise workflow: Rationalise print jobs to avoid prolonged idling of equipment. Centralising print jobs can improve energy efficiency.

Environmental control: Keep the temperature and humidity of the printing environment stable to reduce printing failures and material wastage due to environmental factors.

Supply Chain Management

Procurement Strategy: Establish long-term relationships with suppliers and seek bulk purchase discounts and concessions. Regularly evaluate suppliers and select the most cost-effective material suppliers.

Inventory Management: Optimise inventory management to avoid material expiry or backlog. Use inventory management software to track material usage and replenish inventory in a timely manner.

Logistics Optimisation: Select reliable logistics services to ensure timely and safe delivery of materials and reduce production delays and extra costs caused by logistics problems.

Training and skills upgrading

Staff training: Regularly train operators to improve their skills and efficiency. Skilled operators can reduce print failure rates and material waste.

Technical support: Utilise technical support and training resources provided by the manufacturer to ensure the team is up-to-date with the latest printing technologies and best practices.

Knowledge Sharing: Encourage team members to share their experiences and skills to form a knowledge base that improves overall productivity and cost control.

Quality Control.

Process Monitoring: Real-time monitoring of key parameters during the printing process, timely detection and correction of problems, and reduction of scrap rate.

Testing and calibration: Regularly test and calibrate the printing equipment to ensure its accuracy and stability, avoiding quality problems and material wastage caused by equipment problems.

Standardised operations: Develop and follow standardised operating procedures to ensure consistency and high quality of each print, reducing rework and material waste.


By optimising material usage, design, print efficiency, energy management, supply chain management, as well as upgrading employee skills and strengthening quality control, you can significantly reduce the cost of sand 3D printing and improve economic efficiency. Implementing these strategies will not only help save money, but also improve productivity and product quality, giving your organisation a greater competitive advantage.
