LiM Laser Metal 3D Printer Quality Management: Real-time, Fine-grained, Intelligent, Systematic, Closed-loop

Time：2025-04-01
In the field of metal additive manufacturing, every technological breakthrough is accompanied by a stricter pursuit of quality. LiM Laser has closely followed the principle of “quality first, customer first” and actively explored the quality management mechanism to enhance the competitiveness of its products. Especially in the process of new equipment design and development, in order to eliminate hidden quality problems, LiM Laser scientifically uses DFMEA (Design Failure Mode and Effects Analysis) and other quality management tools to analyze and solve problems, and improve the program, in the stage of product development, to identify the design risks in advance, so as to make the innovation more robust, and make the quality more controllable.
DFMEA: Building quality defense from the design source
DFMEA is not a simple “problem checklist”, but a set of forward-looking risk prevention and control system, which requires systematic analysis of potential failure modes in each link at the early stage of design, assessment of its impact on function, safety and cost, and formulation of preventive measures in advance to ensure that no link is left out. Based on the severity, frequency of occurrence and other locking “high-risk target points”, through the optimization of design solutions and repeated verification tests, the formation of “identification - prevention - verification” of the complete chain, so that the design from 'experience-driven' to 'data-driven'. This enables the design to shift from 'experience-driven' to 'data-driven', to carry out quality control in advance, and to improve product reliability and safety.
Risk identification and prevention: let the failure “nowhere to hide”
Taking a key component of metal 3D printing equipment as an example, the quality department and R&D department applied DFMEA tools to sort out and analyze the structure, function, and parameters, and carried out failure mode identification, influence analysis, and formulation of preventive and control measures, from which medium and high-risk processes that are more risky and not easy to detect were identified. By increasing control and monitoring means, risks are effectively prevented. Continuously multiplying the quality of our products and creating high quality equipment that is easy to use has allowed LiM Laser to stand out in a highly competitive market.
Cost and quality win-win: the “hidden value” of DFMEA.
The cost of quality is not only related to the “yield rate”, but also affects the brand reputation and market competitiveness, and the hidden value of DFMEA is reflected in the following:
Reduce cost and increase efficiency
Early detection of problems avoids the high cost of rework and modification at a later stage, and reduces the cost of warranty and maintenance at a later stage.
Customer Trust
The reliability of the equipment is improved, and the quality and performance of the printed products meet the requirements of the users, which greatly enhances the market competitiveness while maintaining the image of the company.
Compliance Guarantee
DFMEA analysis can ensure that the equipment products comply with industry standards and quality system certification; retain a complete record of the analysis of documents, so that any time, any event can be traced.
Teamwork and Knowledge Precipitation: Creating a “Wisdom Engine”
The use of DFMEA is inseparable from teamwork and cross-functional collaboration, multi-party linkage mechanism to provide comprehensive quality assurance for new product development.
Cross-functional collaboration
Promote collaboration among design, engineering, manufacturing and other departments to ensure the feasibility of new product design.
Knowledge base construction
Accumulate failure mode data and establish a case database to provide a basis for subsequent new product development.
Employee Empowerment
Conduct regular quality management training to improve the team's risk identification efficiency.
LiM Laser recognizes that to ensure the quality of our devices and finished products, we need to control the entire process from prevention, process monitoring to post-tracing. We will continue to build the cornerstone of quality management, constantly find and optimize details, strengthen quality management with high standards and strict requirements, and provide users with high-quality and intelligent metal additive manufacturing solutions.
