Author： Radium laser
Use "iterative thinking" to take the road of advancement. In the previous article, we introduced the basic structure, optical system, forming system, powder laying system, monitoring system and control software of LiM-X400H equipment:
Optical system:High-precision digital galvanometer, low-distortion F-theta focusing mirror, adjustable beam expander, laser M²<1.1, quartz protective mirror.
Forming system:Fully open and customizable. The standard forming size 450x 450x 1500mm adopts IPG500W × 4 fiber laser, Scanlab × 4 high-speed galvanometer and SIL f-θ × 4 field mirror, which can realize a layer thickness of 20-120μm.
Powder spreading system:On the powder, the structure is simple and stable, the amount of powder can be controlled, avoid the introduction of oxygen, always supply powder; double scraper powder, shorten the printing time.
Monitoring system:Double camera monitoring, real-time shooting each powder and printing results, easy to remote monitoring.
Control software:Independent research and development, with special motion control system, with imported servo drive, the introduction of the world's advanced brands (Belgium Materialise) model processing software Magics and BP.
LiM-X400H auxiliary equipment: water cooler
The waterway control system uses an additional water cooler to control the temperature of the circulating waterway of the equipment to be constant, and to cool the optical system and the forming platform at a constant temperature. It uses a single water cooler to control the water cooling of the laser and galvanometer at the same time, and feeds back the temperature and flow of each road in real time. The key components of the equipment in the printing work are always in the same constant temperature environment, so as to ensure the stability of the printing process.
LiM-X400H auxiliary equipment: dust removal and purification cabinet
Under the action of the circulating fan, the air pressure difference is formed in the closed loop, so that the air flow circulates at a certain flow rate and speed in the loop. The dust removal and purification cabinet adopts the form of permanent filter element, which can realize long-term printing without replacing the filter element and ensure the stability of the equipment.
LiM-X400H auxiliary equipment: powder circuit circulation system
The system is composed of powder supply mechanism, old powder recovery mechanism, new powder addition mechanism, tail gas treatment mechanism, cleaning mechanism, control unit, vacuum conveyor and other parts, assisting 3D printer to complete powder supply, old powder recovery and other work.
The powder conveying process of the system is in a closed inert gas protection environment, with low argon consumption, high powder conveying rate, ensuring powder quality, reducing manual participation, and improving safety factor.
Permalloy refers to an iron-nickel alloy with a nickel content in the range of 30% to 90%. This kind of soft magnetic alloy can effectively control the magnetic properties through appropriate process. It is a typical functional material with high permeability, low coercivity, high saturation magnetic induction, high Curie temperature, good corrosion resistance and good processing performance. Mainly used in alternating magnetic field, widely used in aerospace industry and telecommunications, measurement and control system. Commonly used permalloy 1J50, 1J79, 1J85 and so on. In the field of aerospace industry, permalloy is mainly used to manufacture precision components with high sensitivity, fine size, small size and low high frequency loss.
Additive manufacturing combines 3D printing with industrial production, creating a new processing method, and has irreplaceable advantages in the manufacturing of complex structural parts. Recently, Dr. Guan Kai, general manager of Tianjin Radium Laser Technology Co., Ltd., accepted an exclusive interview with MM's "Insight" program and expressed a clear view on the hot topic of additive manufacturing. MM "Insight"
The 6th China (Xi 'an) International 3D Printing Conference and Qin Chuangyuan 3D Printing High-end Forum opened today. Radium Laser was unveiled with LiM-X150A equipment and typical metal 3D printing displays, sharing technological achievements and application cases, discussing the future development direction of additive manufacturing, and going to the digital future together.
