On the early morning of December 19th Beijing time, the ultimate suspense of the Qatar World Cup was finally revealed. Argentina defeated France 4-2 in a penalty shootout to win the championship and win the World Cup, which symbolizes the highest honor in football.
Hercules Cup: 36.8 centimeters high, weighing 6.175 kilograms, with the main body of 4.97 kilograms cast from pure gold; The base is 13 centimeters wide and is embedded with four raised letters carved from malachite called "FIFA". The entire trophy looks like two Hercules holding up the Earth, hence its name.
LiM laser selection of titanium alloy materials, the useSelective Laser Melting Technology for Metal Additive ManufacturingOne-piece forming quickly produces Hercules cup ornaments with unique shape and full of strength.
Hercules Cup Original Mathematical Model
When constructing the model of the Hercules cup, the LiM laser technology team replaced the solid structure design of the original model with the design of the skin lattice structure. While realizing weight reduction, the Hercules cup has good pressure resistance in all directions, and the center of gravity of the parts is close to the middle position, making it more convenient to hold and place.
In the design of the Hercules cup, according to the weight and its strength requirements, the skin thickness is 4mm, the lattice cell size is 5mm, and the rod diameter is set to 0.75mm.
In addition, according to the characteristics of selective laser melting forming process, in order to ensure that the top small angle structure will not have defects such as shortage or warping during printing, dot matrix encryption is carried out on the structure with forming angle <45, and the cell size of the encrypted dot matrix is 2.5mm and the rod diameter is 0.75mm.
Lightweight Hercules Cup model
The advantages of skin lattice structure:
The lightweight processing method of filling lattice inside the outer skin is widely used in the lightweight manufacturing of parts in aerospace and other fields. Mainly has the following advantages:
- Reduce material costs
Lattice structures can reduce material waste by removing most of the material in non-critical areas. The material used to print the Hercules cup is titanium alloy, which is more expensive and can greatly save costs without sacrificing the structural rigidity and integrity of the parts.
Through the lattice structure, the lattice parameters can be precisely adjusted to the physical load on the part, reducing the overall mass of the part by 60% or more.
- High surface area
The lattice structure can provide more curved surfaces and release a large amount of surface area, which has great advantages for products that promote heat exchange. The unique lattice structure can significantly increase the surface area, so as to achieve higher heat exchange efficiency in a more economical way.
- Impact resistance
Lattice structures are very effective in dissipating seismic and impact loads, because the unit structure helps the bending and energy distribution of the entire structure, and the lattice can be integrated into the product to reduce impact stress.
After lightweight design, the theoretical weight of the Hercules cup has been reduced from 3.85kg to 1.5kg, with a weight reduction of more than 60%. The single product is completed from printing to post-processing of parts, and the production cycle can be controlled within 5 days, fully demonstrating the potential of selective laser melting technology in the design and manufacture of lightweight parts and the advantages of rapid production in short cycles.
Metal 3D Printing Powerful Cup
When the traditional processing method is used to manufacture such ornaments, it is necessary to split the three-dimensional model into multiple parts for processing one by one, and finally to carry out splicing and combination, which not only takes a long manufacturing time, but also is difficult to meet the requirements of light weight, and the material loss is much. Metal 3D printing technology can solve these problems.
Digital manufacturing can break the constraints of part structure size, realize the production and manufacturing of parts with more complex structure, smaller size and more precise precision requirements, and make up for the problems of traditional industry production and manual difficulty.
In the future, LiM Laser will continue to play its advantages in metal 3D printing technology and provide various solutions for the production and manufacturing of more complex parts.
Metal 3D printing technology
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.
