As 3D printing adoption continues to expand, demand for IPA to clean parts is increasing in tandem. At Formlabs, we’ve increasingly been having conversations with customers about how to better incorporate sustainability best practices into their print operations. Concerns over the environmental impact of consuming large quantities of IPA, especially for companies printing with a significant amount of resin each week, have many looking for ways to recycle and reuse IPA.
Carrier Solvents in Extraction:
Ethanol vs Butane
It is true, both Ethanol and Butane (also referred to as Hydrocarbon) can be used to extract oil from cannabis and hemp. When considering which solvent to use, a processor should carefully review the safety, efficacy and working history of a given solvent in application. Operating costs can be masked and provide a false positive to select a solvent because it is less expensive to purchase, when, it is more expensive to use. This blog will explain some of these differences between Ethanol and Butane and will help guide a processor to make more informed and better decisions regarding extraction methods and carrier solvents used in these same extraction methods.
