Metal 3D printing makes it easier to manufacture complex flow patterns
Author： LiM Laser
In recent years, with the mature application of laser selective melting (SLM) technology, its advantages in producing complex flow pattern and pore structure parts have become increasingly apparent. This technology can avoid defects such as shrinkage porosity and porosity in traditional casting processes, and the part density can reach 99%.

The LiM laser uses self-developedLiM-X260 Series Selective Laser Melting EquipmentA typical piece of complex flow type pore structure is printed. The typical piece of pipe extends in all directions, staggered and complicated, and the inner diameter of each pipe of the part is different.The process team realized the smooth production of the part by adjusting the forming direction of the part and adding support appropriately. The inner surface roughness of the blank can reach Ra6.3μm. Through the post-treatment process such as abrasive flow, the inner runner roughness of the blank is further optimized.

LiM laser also uses LiM-X260 series equipment to print the cross hole structure made of die steel, and its cross hole diameter is 10mm-20mm, which can still maintain good roundness.

The continuous development of the manufacturing industry has also put forward new requirements for mold manufacturing: in addition to the complex structure, it requires high manufacturing precision, strong reliability, and long service life... It is difficult to process using traditional processes. The metal 3D printing technology has the characteristics of short production cycle and low cost of small batch production, so it has technical advantages for mold manufacturing, especially for the production of complex flow-type pore structure parts. In recent years, it has begun to show its edge in the field of domestic mold manufacturing.In practical application, LiM Laser used self-developed LiM-X400D equipment to print blank parts made of die steel for a car company. The profile of the inner flow channel of the part shows that the roughness of the inner hole is better and the overall quality of the round hole is higher.

Under the promotion of "intelligent manufacturing power", LiM laser will rely on years of accumulated experience in metal 3D printing technology, constantly break through the barriers of 3D printing technology, dig deep into the application field, and provide users in various industries with better equipment and more mature solutions.
Metal 3D printing
LiM Laser AMS-SLM pre-processing software independently developed by LiM Laser is suitable for the company's own laser selective melting equipment. Its functions include digital model creation, 3D STL part import, 2D CLI profile data import, part movement/rotation/slicing/path planning, etc.
With the accelerated development of the manufacturing industry, enterprises have increasingly stringent requirements for mold accuracy, structural complexity, production cycle and cost, and traditional mold manufacturing technology can no longer fully meet market demand. Among the many new technologies, metal 3D printing technology brings a new development direction for the mold industry with its unique technical advantages.
Strengthening management is the eternal theme of enterprise development. As the domestic head of metal 3D printing equipment manufacturer, LiM Laser fully implements lean management requirements and takes quality management as the top priority. In this process, LiM Laser Science uses "5M1E1I" and other analytical tools to solve problems and improve methods, and on this basis, it has established a complete quality management system to promote the high-quality development of the enterprise.
