BOFA Air Extractors for All 3D Printing Technologies

Ensure a Healthy & Safe 3D Printing Environment with BOFA PrintPRO Air Purifiers

The rapid advancement of additive manufacturing technologies has revolutionized countless industries, enabling unparalleled design freedom and production capabilities. However, with the widespread adoption of 3D printing across various processes such as Fused Deposition Modeling (FDM), Stereolithography (SLA), Digital Light Processing (DLP), Multi Jet Fusion (MJF), Selective Laser Sintering (SLS), and many others, a critical concern has emerged: the emission of harmful airborne particles. During the 3D printing process, regardless of the specific technology employed, a range of fine particles and gases are inevitably released into the surrounding atmosphere. This issue is particularly pronounced when processing common polymers like PLA, PETG, and ABS, as well as various resins and metal powders used in more advanced systems.

Extensive research, including studies conducted by reputable institutions such as the Georgia Institute of Technology and Fraunhofer WKI, has conclusively demonstrated that 3D printing operations can generate over 200 distinct types of Volatile Organic Compounds (VOCs) and Ultra Fine Particles (UFPs). These emissions are not merely a nuisance, causing unpleasant odors and impacting the working environment’s comfort; they pose significant health risks to individuals exposed to them without adequate protection. Prolonged or frequent exposure to these airborne contaminants can lead to respiratory issues, headaches, eye irritation, and other serious health complications. Therefore, implementing proper ventilation and air purification solutions is not just a recommendation but an absolute necessity for anyone operating a 3D printer, whether in a professional workshop, an educational setting, or a home office.

The commitment of BOFA to developing industry-specific solutions, coupled with Atome3D’s robust distribution network, underscores the importance of addressing air quality in the rapidly evolving landscape of additive manufacturing.

Advanced Filtration Technology: The Heart of PrintPRO Extractors

The BOFA PrintPRO range comprises a versatile selection of four machines: the PrintPRO 1, 2, 3, and 4. These models are designed to cater to various types and sizes of 3D printers and different operational scales, offering scalable solutions for diverse requirements. While pricing varies across the range (e.g., PrintPRO 1 at €390, PrintPRO 2 at €649.90, PrintPRO 3 at €729.90, and PrintPRO 4 at €1,490.90, prices excluding tax), the core differences lie in their extraction power, processing volume, and ultimately, their filtration capacity and efficiency. Each model is engineered to deliver robust performance, ensuring optimal air quality control tailored to specific demands.

At the core of every BOFA PrintPRO extractor is a sophisticated dual-level filtration system, meticulously designed to capture a broad spectrum of airborne contaminants. The first and most critical stage of filtration involves a high-efficiency particulate air (HEPA) filter. This advanced filter is capable of capturing an astonishing 99.97% of particles as small as 0.3 microns. To put this into perspective, 0.3 microns represents the Most Penetrating Particle Size (MPPS) – particles both smaller and larger than this are generally captured with even higher efficiency. This HEPA filter effectively removes harmful solid particles, including fine dust, aerosolized material, and various ultra-fine particulate matter, preventing them from entering the breathing zone.

Following the HEPA stage, the air passes through a robust activated carbon filter. This second level of filtration is specifically engineered to address gaseous contaminants, odors, and nanoparticles that HEPA filters might not fully capture. Activated carbon, with its highly porous structure and immense surface area, works through a process called adsorption. It effectively traps Volatile Organic Compounds (VOCs) such as styrene from SLA resins, as well as various aldehydes, ketones, and other noxious gases emitted by heated filaments like ABS. The activated carbon also plays a crucial role in eliminating the unpleasant odors often associated with 3D printing, creating a much more comfortable and productive working environment.

Optimized Performance and Extended Filter Life

To ensure the activated carbon filter performs at its peak, BOFA has integrated a unique labyrinth-like network system into its design. This innovative feature is engineered to slow down the airflow as it passes through the activated carbon media, significantly increasing the contact time between the contaminated air and the adsorptive material. This extended contact time is crucial for maximizing the capture efficiency of VOCs, gases, and odors, ensuring comprehensive air purification. Without sufficient contact, many gaseous contaminants could pass through untreated, undermining the effectiveness of the system.

Furthermore, to provide long-lasting and consistent filtration performance, BOFA has equipped the PrintPRO extractors with intelligent sensors. These advanced sensors continuously monitor the efficiency and service life of both the HEPA and activated carbon filters. This proactive monitoring system alerts users when filter replacement is needed, preventing compromised air quality due to clogged or saturated filters. This feature not only ensures sustained protection but also helps in optimizing maintenance schedules and reducing operational downtime.

An additional layer of protection and efficiency is offered in the PrintPRO 2, 3, and 4 models through the inclusion of a pre-filter. Unlike the PrintPRO 1, these more advanced units incorporate a high-capacity pre-filter designed to capture larger particulate matter before it reaches the finer HEPA and activated carbon filters. This pre-filter is highly effective, removing 95% of particles as large as 1 micron and 80% of particles down to 0.2 microns. By handling the bulk of the larger dust and debris, the pre-filter significantly extends the lifespan of the more expensive HEPA and chemical filters, leading to substantial cost savings and reduced frequency of filter changes, all while maintaining superior air purification performance.

Versatile Application: Exhaust, Recirculation, and Temperature Control

The BOFA PrintPRO extractors offer exceptional versatility in their application, adapting to various workspace configurations and printing requirements. They can be deployed in two primary modes: direct exhaust and air recirculation. In the direct exhaust mode, the system captures contaminated air from the 3D printer and expels the purified air either into the general workroom environment or directly outside the building. This is suitable for environments where temperature stability is not a critical factor, or where there is ample make-up air.

However, a particularly advantageous feature of the PrintPRO systems is their ability to recirculate air within a closed printing enclosure. This recirculation capability is invaluable, especially for materials that are sensitive to temperature variations or require a stable, elevated temperature for optimal printing performance. For example, materials like ABS, Nylon, Polycarbonate, and various engineering-grade filaments often demand a heated build chamber to prevent warping, improve layer adhesion, and ensure consistent print quality. Traditional exhaust systems can draw in cooler ambient air, making it difficult to maintain the required internal chamber temperature.

With the recirculation system, the PrintPRO extractor draws air from the print chamber, purifies it, and then returns the clean air back into the same enclosure. This closed-loop approach allows for continuous air purification within the printing environment without affecting its thermal stability. By maintaining a constant internal temperature, the PrintPRO system helps to achieve superior print quality, reduce material waste, and broaden the range of materials that can be successfully printed. This makes it an indispensable tool for advanced manufacturing applications where precision and material integrity are paramount.
