3D Fuel Inspiring Green 1.75mm Advanced PLA (APLA) filament is manufactured with pride in the USA. The 3D Fuel filament extrusion process uses a dual axis micrometer measurement system to check the diameter and roundness during production. This helps guarantee that each spool of 3D Fuel filament is produced with precision tolerance of ±.05mm. Within minutes of production, each spool of 3D Fuel filament is vacuum sealed with a moisture desiccant enclosed, along with a moisture indicator, to ensure that your filament is ready for 3D printing as soon as you take it out of the box. Each roll of 3D Fuel filament contains 1kg of material.
BOFA Americas Overview:
If you are 3D printing, you need to be aware of the associated potential Health & Safety risks of the toxic fumes and particulate that are emitted from 3D printing processes and use an effective fume extraction and filtration system to remove these risks from your operators’ breathing zone. BOFA offers a range of specialist systems designed specifically to help you achieve this.
The Need For Fume Extraction...
3D printing processes that heat materials cause particles, droplets and gases to be released that can be harmful if inhaled.
Health & Safety
A current report suggests a growing awareness of potential Health & Safety issues and, in particular, the harmful presence of ‘nano particles’ within fumes created by 3D printing. These particles and droplets are too small to be seen by the naked eye, but just because you can’t see them, doesn’t mean the dangers for operators don’t exist!
In fact, particles in the nanosize range may be able to cross more readily into the bloodstream after inhalation, and the toxicological effects may differ from those resulting from exposure to the same material in a more conventional size or form.
Fumes given off by ABS have a particularly unpleasant odour, and other plastics, including Nylon, HIPS and HDPE, generate fumes that are equally toxic, but less noticeable.
Polymeric materials can release constituent materials, in the case of laser processing in particular, including carcinogens such as benzene. Polymers also frequently contain additives, such as di-octyl-phthalate, to increase flexibility or to act as mold release agents. These vaporize and condense at much lower temperatures to form oily type liquids. Plastics containing chlorides, such as PVC, can release HCL gas when lasered, which combines with airborne moisture to form hydrochloric acid droplets.
The high temperatures generated in 3D printing processes cause the air close to the source to expand and rapidly project the gases and particles rapidly into the technician’s breathing zone.
Plus, curing processes associated with using liquid resins cause potentially harmful solvent gases to be released into an operative’s breathing zone.
Productivity & Quality
In addition to Health & Safety concerns, the prolonged release of sticky plastic droplets from the 3D printing process can lead to a build-up of material on the printer’s moving parts, requiring additional maintenance and potentially causing reliability issues.
The BOFA Solution...
The use of an effective fume extraction and filtration system protects operatives from potentially harmful fumes; avoids the risk of costly Health & Safety litigation for the employer; and maintains the reliability of the printer.
Having carried out a detailed study of the 3D printing industry, BOFA has developed three fume control solutions to cover each of the main 3D printing formats.
The BOFA 3D PrintPRO range has been designed to capture and filter out harmful airborne toxic gases and particulate from open frame, table-top enclosed / partially enclosed and fully enclosed 3D printers, without causing the filament deposition to be cooled prematurely. The filter design includes Health and Safety compliant HEPA grade particulate filter media, which has an efficiency of 99.997% at 0.3m, and deep bed activated carbon filters to remove organic gases and vapors.
