Filter bag DELFIN - for Formlabs vacuum cleaner

Filter bag DELFIN - for Formlabs vacuum cleaner

Purpose and Application

The replaceable DELFIN filter bag, class M, is specifically designed for the industrial vacuum cleaner MTL 300 BL (ATEX), an integral part of the Formlabs Fuse Sift post-processing ecosystem for selective laser sintering (SLS). This component ensures efficient filtration of fine polymer powder during workspace cleaning, maintaining cleanliness in the additive manufacturing process.

The use of DELFIN filter bags is critical for companies working with SLS 3D printing technology, as it allows safe collection and disposal of unsintered powder, maintaining a sterile production environment and protecting the health of personnel.

Technical Specifications

Key Parameters

The filter bag has a working volume of 7 liters and is made of anti-static material that meets class M standards for industrial filtration. The disposable design ensures maximum hygiene and eliminates the risk of secondary contamination.

Compatibility and Integration

The filter is fully compatible with the Industrial Vacuum 230V (model MTL 300 BL - ATEX), used in conjunction with the Formlabs Fuse Sift powder recower station. The integrated system ensures a sealed connection, preventing the leakage of fine particles during operation.

Advantages in Industrial Environments

Filtration Efficiency

The DELFIN filter bag provides a multi-stage air filtration system, working in combination with the vacuum cleaner’s HEPA filter. This allows capturing particles down to micron sizes, which is especially important when working with SLS polymer materials.

Cost Efficiency

Using replaceable filter bags optimizes operational costs by:

• Enabling quick and easy replacement without stopping the production process;
• Preventing contamination of the main vacuum filters, extending their service life;
• Allowing safe disposal of waste along with the bag.

Safety and Environmental Benefits

The disposable bag design minimizes operator contact with fine powder during equipment maintenance. This complies with modern occupational safety standards and reduces the risk of work-related illnesses associated with inhaling industrial dust.

Usage Recommendations

Replacement Frequency

The replacement interval depends on the intensity of the SLS printer’s use. For a standard production cycle, it is recommended to replace the bag after accumulating 8–9 liters of material or if the vacuum’s suction power decreases.

Installation Procedure

Filter bag replacement must follow the manufacturer’s instructions, observing all safety precautions. Before installing a new bag, ensure that sealing surfaces are clean and mounting points are undamaged.

Integration into the Formlabs Fuse Ecosystem

DELFIN filter bags are a critical component of the closed Fuse Sift post-processing system, which allows up to 70% of used powder to be recycled. Efficient filtration helps maintain negative pressure inside the workspace, preventing the spread of polymer particles into the surrounding environment.
