At EOS, we are dedicated to improving the manufacturing process so that companies can reduce emissions, recycle more, and promote sustainability through setting a positive example. That’s why we have created a certified carbon neutral impact material solution for advanced additive manufacturing (AM).Get more news about pa powder printing,you can vist our website!
A carbon-neutral operation reduces a business’ carbon dioxide footprint so that emissions do not exceed the amount that is offset, creating a zero net emission for carbon dioxide. EOS and Advanced Laser Materials (ALM) — an EOS company — have achieved this with the polyamide 11 polymers thanks to a combination of the bio-based nature of the powder and the methodology of the material production.
The polyamide 11 powders were developed by Arkema, renowned as a pioneering innovator in castor-based high-performance polymers. With the help of ALM, Polyamide 11 powder solutions have been certified as carbon neutral. This is thanks to ALM’s additional steps to offset ancillary carbon generation by installing solar panels at their Texas headquarters and investing in Gold Standard carbon credits from the MyClimate solar project in Ethiopia. The process for producing the PA11 powder begins simply with castor beans. This resource is an excellent candidate for producing polymer because it grows easily in India in marginal soil, is highly drought-resistant, and offers good profits for the farmers who grow it. Where other edible oils would not flourish in these same conditions, farmers are able to expand crops to supply the increased demand for castor beans brought about by the development of PA 11 powders. This has seen castor bean farming profiting more than half a million families in the areas it’s grown.
The castor beans are crushed to produce an oil, which resembles many standard vegetable oils. The oil is processed by Arkema to produce a monomer powder, which can then be further developed to create a polymer powder for injection molding and 3D printing.
To make the powder suitable for laser bed fusion printing required the expertise of ALM to formulate adjustments to the powder so that it will function properly in an AM system. ALM produces this powder under the name PA 820-MF CN. The material is available to purchase directly from EOS, it is suitable for use with the EOS P 396 and EOS P 770.
