Zhizhi Technology Releases Orthopedic Medical Special Electron Beam Metal 3D Printer QBEAM Med200
On February 22, 2019, Tianjin Qingyan Zhibeam Technology Co., Ltd. (hereinafter referred to as "Zhibeam Technology") released the self-developed QBEAM Med200, a special electron beam metal 3D printer for orthopedic medicine, at the 2019 Asian Additive Manufacturing Exhibition TCT.
QbeamMed200 type equipment
Equipment parameters:
At present, many medical device companies and orthopedic hospitals at home and abroad choose to use electron beam 3D printing technology to produce standardized and personalized orthopedic implants. Compared with laser metal 3D printing (SLM), electron beam metal 3D printing has obvious advantages in manufacturing capacity and manufacturing cost.
Taking the acetabular cup with trabecular bone structure as an example, the manufacturing capacity of electron beam metal 3D printing is about 3 times that of laser metal 3D printing (SLM) in the same effective forming space. Because electron beam metal 3D printing has the characteristics of 3KW energy source, substrate temperature above 700 degrees C and layer-by-layer preheating, so that the implant can be stacked in the printing process and save the time and cost of line cutting and heat treatment after printing. At the same time, compared with the inert gas protection environment of laser metal 3D printing (SLM), the vacuum environment of electron beam metal 3D printing is more beneficial to the oxygen content control of the implant.
Taking the acetabular cup with trabecular bone structure as an example, according to the calculation of foreign authoritative institutions, the total manufacturing cost of using electron beam metal 3D printing process from powder raw materials to printing to post-processing to obtain a final acetabular cup product is half of the cost of using laser metal 3D printing (SLM) process to manufacture acetabular cup products.
QBEAM Med Orthopedic Medical Special Electron Beam Metal 3D Printer has optimized the design of electron gun, powder spreading system, control software and quality control on the basis of the previous generation of QbeamLab equipment.
1. A new generation of electron gun using single crystal filament, compared with the traditional tungsten filament with 10 times longer life, the emission of electron beam brightness increased by 10 times. The filament life can reach 800 hours and the minimum beam spot diameter is 150 microns.
2. The two-way powder feeding method is adopted, which is matched with the powder spreading integrity detection and residual powder weight monitoring technology, with higher efficiency and more stable process.
3. The updated printing process control software provides a more friendly operation interface, and increases the production mode, which can automatically complete all processes such as vacuum, printing, and cooling with one key.
4. The quality monitoring is upgraded from the traditional optical camera to the secondary electronic layer-by-layer imaging technology, which makes the monitoring and recording of the printing process clearer and more accurate.
QBEAM Med200 equipment high quality spherical metal powder and Ti6Al4V process package at the same time, and provides all-round technical support for the 3D printing process of new materials required by users in the medical field.
The first QBEAM Med200 will soon be delivered to a domestic orthopedic hospital, and combined with digital diagnosis and treatment, personalized design and other technologies to provide high-quality medical services for orthopedic patients. Orthopedic digital precision medical technology program for the benefit of people's health, is the value of intellectual beam technology proud pursuit.
Zhibeam Technology respects and attaches great importance to intellectual property rights, inherits the research and development achievements of Tsinghua University for more than ten years, independently develops key core technologies such as electron beam wide scanning control, electron beam preheating, element evaporation suppression, online detection, etc., and applies for and obtains authorized invention patents 8 items, more than 10 utility models, and 2 registered software copyrights, breaking through the technical monopoly of foreign companies, A selective electron beam melting equipment and process system with China's independent intellectual property rights has been formed.
