How to use 3D printing V8 engine with metal powder
From metal powder melting through layers, through metal CNC machining, to the formation of a brand new V8 engine, which was previously incredible, and with the combination of 3D printing technology and CNC metal cutting technology, from powder to engine, everything It’s all in one go.
In the field of mixed metal 3D printing, it is divided into two major factions according to the different 3D printing technology. A large faction is represented by Japan's Matsuura and Japan's Sodick, combining PBF powder metal melting 3D printing technology with CNC metal cutting technology into one piece of equipment; the other faction is Germany's DMG Giessen Seiki, Japan Mazar Ke et al. represented LENS laser near-net shape 3D printing technology and CNC metal cutting technology into one device. The former does not use coolant in the process of metal cutting, and the metal cutting process is alternated with the PBF powder metal melting 3D printing process; the latter usually has the use of coolant during metal cutting, and metal cutting The process is performed after the end of the LENS laser near net shape 3D printing process.
If you look at the work area, many people will "prong" the hybrid additive manufacturing equipment that combines PBF powder metal melting 3D printing technology with CNC metal cutting technology. It is a pure PBF powder metal melting 3D printing device because there is no coolant. Spraying, and there is not a lot of chip breaking, this is a special feature of this kind of mixed additive manufacturing equipment: everything is quiet and quiet...
Matsuura, Japan
Since 2015, GE Oil & Gas has used Matsuura Additives to manufacture compound-machined milling machines to manufacture specially configured Masoneilan control valve components at its Kariwa plant in Niigata Prefecture, Japan, for a variety of applications throughout the energy industry.
GE acquired the Yu Yu factory in 2011. Two years later, it began testing special valves with 3D printers. These special valves have a lot of small holes and flow channels that have been difficult to manufacture and used to be assembled with many parts. GE's feather factory uses the LUMOSAvance-25 metal 3D printer. The use of metal 3D printers enables GE to manufacture parts with complex shapes, such as hollow structures, curved shapes and meshes, which are difficult to manufacture using conventional manufacturing methods. Another benefit is that it enables integrated molding, which reduces the need for processing molds in traditional manufacturing processes, enabling faster manufacturing times and lower manufacturing costs.
An example of a metal 3D printing technology that can substantially shorten the production cycle is that it can reduce the number of parts of a particular shape from the traditional three-month production cycle to about two weeks.
Sodick
Since the launch of the OPM250L metal hybrid additive manufacturing equipment in 2014, Sodick has introduced the OPM350L, a precision metal 3D printer driven by a linear motor. The OPM350L uses parallel mode to increase the speed of the model. And the use of automatic material elimination, automatic supply device to achieve continuous production, to meet the needs of large-scale, diversified metal parts mixed additive manufacturing.
Single-process milling is a new fully automated machining method from Sodick. The metal powder can be melted by a laser and then processed by a rotary cutter. In the manufacture of injection molds, complex shape processing with conformal cooling channels and deep ribs can be accomplished with only one Sodick device.
High-speed control of the laser through parallel mode makes multiple simultaneous processing possible. In addition, according to the 3D shape of the shape, the number of layers of the laser is optimized with the balance of the tool cutting process, and the cutting practice is greatly shortened.
The new computer numerical control device LN4RP developed by Sodick is equipped with a high-performance linear motor independently developed and manufactured. Using CAD design and temperature simulation by CAE, the CAD data is designed to be converted into a special CAM "OS-FLASH" into a numerical control program, then the OPM350L can be used to complete the mold manufacturing process.
