With the rapid development of metal selective laser melting (SLM) printing technology, the popularity of the metal 3D printing market is steadily increasing. Although this technology has demonstrated many significant advantages, at the same time, the security risks involved cannot be ignored. The risk of filter element explosion has always been an important safety hazard in this industry. In recent years, cases of filter element explosion have frequently caused bloody lessons, making it urgent to pay attention to and strengthen the safety management of the 3D printing process.
1. Metal powder may spontaneously ignite due to excessive temperature or excessive accumulation during the printing process, causing the filter element to explode;
2. During the printing process, the equipment may be overheated due to improper control or malfunction, which may cause the filter element to burn;
3. The operator's negligence or improper operation may also cause damage or blockage of the filter element, which may cause the risk of explosion and cause casualties.
Common operating errors include not turning on or off the equipment in the prescribed order, and not cleaning and maintaining the filter element regularly. In addition, if the operator fails to replace the filter element in accordance with the prescribed operating procedures, the filter element may be damaged or overheated, causing it to spontaneously ignite in the air. If the company has insufficient training on how to deal with this situation, using the wrong handling method can easily cause the filter element to be damaged. The explosion caused casualties and caused major safety accidents!
In order to effectively reduce the safety hazards caused by replacing filter elements during the metal 3D printing process, we also solve major safety hazards such as filter element explosion.
Since the beginning of equipment development, FASTFORM has paid great attention to the overall stability of the equipment and the development of safety measures. As the first domestic metal 3D printing equipment manufacturer to implement permanent filter elements as standard for all products, Fastform has paid special attention to the safety hazards of filter elements and has conducted in-depth research in the field of "permanent filter elements" for more than five years. Research . Currently, all lines of equipment manufactured by FASTFORM are equipped with permanent filters as standard to provide a safer and more reliable printing environment.
The principle of permanent filter element:
"Permanent filter element" means that the design or material of the filter element makes it have an ultra-long service life, or it can be repeatedly cleaned and regenerated in some way, thereby avoiding frequent replacement. This may reduce the user's maintenance costs and environmental burden. For metal 3D, the application of "permanent filter element" can solve the problem of explosion caused by replacing the filter element to the greatest extent, helping enterprises to improve safety levels and reduce safety risks!
The "permanent filter elements" currently used in the 3D industry on the market usually have a service life of 20,000-26,000 hours, while the "permanent filter elements" used in FASTFORM equipment are made of PTFE material, which has the longest service life on the market and has excellent Acid and alkali resistance, corrosion resistance and high lubricity.
After more than five years of in-depth research, FASTFORM has continuously optimized and designed the filter element for the metal 3D printing industry. After fastform special process treatment, the service life of the filter element has been significantly extended. At present, our company has realized the filter element It has excellent performance with a working time of more than 30,000 hours , thereby solving the problem of explosion that may be caused by misoperation by users during operation.
In addition, to address safety issues that may arise due to excessive powder accumulation during the metal printing process, FASTFORM independently developed the advanced control software fastfab. The software can monitor the operating status of the filter element in real time and effectively prevent metal powder from being accumulated too high or too densely during the printing process. At the same time, fastfab can also monitor key parameters such as substrate temperature and cabin pressure in real time during the printing process , helping users achieve safe and efficient production operations.
By continuously optimizing equipment design and safety performance, fastform committed to providing users with more professional, safe and efficient metal 3D printing equipment and promoting the continuous progress and development of industry technology.
FASTFORM has launched the newly developed multifunctional dental and industrial-grade metal 3D printer - FF-220 model. This device has officially become part of our expanding product line. Compared with the previous FF-140c model, the FF-220 has achieved significant improvements in printing efficiency and has a larger build platform size of 220×140×100/200 mm, allowing users to handle larger builds project.
Designed to meet the precise requirements of dental and industrial metal 3D printing services, this model incorporates dual laser technology to optimize printing speed and accuracy, ensuring high efficiency and high-quality printing results for users. Through this breakthrough innovation, FastForm aims at software-defined manufacturing and is committed to creating an open cooperation platform for metal additive manufacturing.
