3D Printing Fumes

Remove the fume from 3D printing.

 

3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file.

The creation of a 3D printed object is achieved using additive processes. In an additive process, an object is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.

The variety of materials used in 3D printing is very broad. It includes plastics, ceramics, resins, metals, sand, textiles, biomaterials, glass, food and even lunar dust! Most of these materials give off unpleasant odour from Acrylonitrile, Butadiene and Styrene polymers (ABS) are not healthy to breathe in.  Polylactic Acid (PLA) may release toxic fumes known as VOCs (Volatile Organic Carbon). Not all VOCs are actually toxic, but some may be. 

A lab test showed that ABS is significantly more toxic than PLA, but that the corn-based polymer is not exempt from dangerous emissions, especially if extruded at temperatures higher than 200°C. 

Among the effects that the absorption of toxic VOC’s and nanoparticles can cause to humans, the most common are pulmonary pathologies, such as bronchitis, tracheitis, asthma. In some cases, these substances can also cause certain types of cancers, so this is not something to be taken lightly. The solution, however, is not too complicated, connect a fume extraction system to the unit.  

 

Our systems limit employee exposure to harmful pollution, satisfy the strict environmental and health & safety regulation.  Within our range of services we can design, supply, install, test and commission all systems.
