3D Printing Powders Vibrating Sieve

Introduction to 3D Printing Powders Vibrating Sieve

3D printing powders vibrating sieve is used to pre-screen powder before loading on 3D printer, our screening system is equipped with ultrasonic screening system and gas protection device, which can quickly check powder screening, giving manufacturers the opportunity to effectively remove the most The fine powder particles are then loaded into the 3D printer. The secondary screening process involves recycling powder after part production, this recycled powder is collected and run through our vibrating sieve, and with the price of these fines, screeners can pay for themselves within a short period of time.

The whole machine of 3D printing powders vibrating sieve adopts explosion-proof standard design, with good grounding system design, multiple protection to prevent frictional static electricity between powder and mesh surface to the greatest extent, so that the minimum ignition energy is controlled at 3mJ to avoid dust explosion.

Applications of 3D Printing Powders Vibrating Sieve 

3D printing powders vibrating sieve can refine and screen out impurities commonly found in 3D printing materials to improve purity.

Different applications and 3-D machines use various raw materials. Some of the most common include:

Powder Metals and Metal Alloys

Thermoplastics and Thermosets

Ceramics

Working Priciple of 3D Printing Powders Vibrating Sieve

The 3D printing powders vibrating sieve is equipped with a gas protection device, the part in contact with the material is made of 304 material, and a vertical vibration motor is used as the excitation source. Vertical and inclined three-dimensional motion, and then transmit this motion to the screen surface, the material larger than the screen hole size is left on the screen surface and discharged from the coarse material discharge port, and the material smaller than the screen hole size falls into the lower layer. According to the vibrating sieve Design, you can configure 1-5 layers of screen to achieve particle size classification.

Benefits of 3D Printing Powders Vibrating Sieve

1. 3D printing powders, especially the particles smaller than 5um, are more harmful to the human body. During the whole screening process, the powder is completely in a closed inert gas atmosphere, which effectively prevents the operator from directly contacting the powder.

2. The whole machine adopts the explosion-proof standard design, with a good grounding system design, multiple protections to prevent the frictional static electricity between the powder and the mesh surface to the greatest extent, so that the minimum ignition energy is controlled at 3mJ to avoid dust explosion.

3. Combining the dual functions of ultrasonic system and motor vibration, the screening efficiency is greatly improved. The high-frequency and large-amplitude mechanical vibration of the motor evenly coats the powder on the screen surface, allowing small particles to pass through the screen and large particles to be excluded. The acoustic wave conduction system transmits the ultra-high frequency small amplitude acoustic wave energy to the screen mesh wire, destroys the surface tension of the mesh wire, avoids the adsorption of fine powder, reduces the blockage probability of the screen mesh, and promotes the fine powder to pass through the mesh, so as to achieve fine screening. The purpose of powder or easily adsorbed powder.

4. The laser sintering process of 3D printing powders will be accompanied by the generation of metal condensed substances. The mixing of these substances in the powder will cause powder pollution and affect the quality of the powder; The metal powder that causes 3D printing is recycled only 7-9 times. 3D printing powders vibrating sieve's complete inert gas protective atmosphere and efficient screening process can effectively ensure the purity of the powder. In theory, the powder can be recycled infinitely, which can effectively save the user's cost; The exhaust gas generated by the inert gas replacement process can be effectively discharged outdoors, and at the same time, there is a particle recovery port, and the vacuum cleaner can be docked to absorb the large particles and sundries that are difficult to pass through the net, so as to meet the environmental protection requirements of the factory.

5. In addition to the standard version, explosion-proof ultrasonic vibrating screen can also provide corresponding customized services for different customers, and be a "professional metal 3D printing explosion-proof equipment supplier".
