• Ultra-elevated configuration + International experts design to ensure stability;
More than 200 adjustable variables to obtain flexible modulation of minimum beach parameters: The equipment control system can carry out control of the scripted printing process via a fully open process parameter control system. The print process script can be personalized to program, including personalized laser power parameters, scanning speed, jumping speed, lighting time, powdered power supply, powder supply speed, powder installation speed, scanning sequence, addition of parts or deletion, part of the room position, the room copy, etc. In any layer of any part, and the printing process can be a break and printing parameters can be modified online during the print process.
Taking the modification of the power of the printing laser and the scanning speed as an example, the figure below shows parts with large changes in the transverse section of the printing part. Since the transverse size of the first ten layers of the parts is small, in order to better control the laser heat input, the first ten layers are selected via the “IF” judgment order, and the power of the printing laser and the speed of the first ten layers are modified via the “LPower” and “V_Mark” instructions. For other print layers, the power and speed of the conventional print laser is used.
The standard substrate forming web is preheated to 200 ℃ and 500 ℃ Substrate preheated to 500 ℃ to solve problems such as hardware cracking and residual stress, considerably reducing the risks of stratification, deformation and cracking. It is particularly suitable for research in prospective technology and the development of new materials and new processes such as universities and research institutes.
Scenarios applicable for preheating at high temperature:
• Reduce deformation and cracking: for high residual stress materials such as high -temperature titanium alloys, higher preheating temperatures reduce the temperature difference between the melting pool and surrounding materials, reduce the cooling rate, thus reducing the deformation and cracking of the company caused by thermal constraint;
• Reduce the trend of cracks: for materials subject to cracks (such as high temperature alloys based on nickel), preheating can alleviate microfissures caused by rapid cooling.
• Improve the resistance of the inter-layer bond: the high temperature environment reduces the temperature difference between the newly deposited layer and the hardened layer, promotes atomic diffusion, improves inter-layer fusion and reduces efusion defects.
• Reduce pores and defects: high temperatures help the fusion swimming pool flow more fully and reduce pores and poor fusion.
The high temperature alloy based on Nickel Hastelloy X-Print: 500 degrees Preheating reduces cooling speed, effectively inhibits the liquefaction of grain boundaries, reduces inter-fed deformation, promotes the diffusion of elements, reduces local segregation, increases density to more than 99.9% and reduces the density of crack by more than 85%.

“Micron high precision metal printing is unknown and needs research and development urgency”
The team of Professor Hao Shijie of the Chinese University of the Petroleum University (Beijing) and the University of Australia-Western, Yunyao Shenwei (Jiangsu) Technology Co., Ltd. and Germany Aixway3d Co., Ltd. Manufacturing “. On the basis of the use of small laser spots, small powder particles and a small thickness of a powder layer, this paper optimizes the combination of the laser power and the scanning rate to obtain excellent formation performance with high density and low surface roughness. The difference between scanning my only μ-lpbf channel and the Multichannel Multichannel Balayage is analyzed From view of thermal history.
The research team of Mr. Zhai Zirong of the Center for Intelligent Manufacturing System Engineering (Case) of the School of Creative Arts of the University of Shanghai Science and Technology has published the article “Microstructure and Mechanical Property Comparison of International Alloys manufactured using micro and conventional laser powder” design”. Research results show that the energy supply of small and medium stains of fine μ-lpbf (the diameter of the point drops from 80 μm traditional to 20 μm) can increase the speed of solidification. When the growth of the temperature gradient is limited, the transformation of column crystals into isometric crystals can always be favored, thus creating fine crystals, high temperature high temperature alloy structures and the yield intensity in the same direction is significantly improved. This work provides an important scientific basis for studying the potential and challenges of micro μ-lpbf technology in the manufacture of micro characteristics.
