3D Printing Materials Off Gassing

As more companies, schools, organizations and home owners begin to put 3D Printers into their facilities there is a growing awareness that some of the materials used for 3D Printing may  generate some odors during the printing process.

This is due, primarily , to the high temperatures at which most 3D filament ( FDM Printers )  operate. For something like the common PLA materials ( Polyactic Acid – Corn Starch ) is extruded at a temperature between 205 and 220 degrees C. This is around 420 degress F. When printing with PLA there is a mild, sweet smell generated and it is very benign.

For materials like ABS (Acrylonitrile Butadiene Styrene or ABS-Polycarbonate ) there are some issues with off-gassing of the ABS as it can produce a somewhat strong odor and some of the gasses could create respiratory issues for some individuals.

Granular activated carbon filters and media, as manufactured by D-Mark, Inc. , are used in some enclosure devices to assist in removing much of the odors and gaseous pollutants generated by the 3D Printer.

D-Mark has been in business since 1970 and has over 45 years of experience in making and designing adsorption products for over 400 organic and inorganic compounds. Their CarbonWeb materials are used exclusively in the LiteWorld Protective Enclosures (www.liteworldllc.com) used to enclose many of the larger FDM style 3D Printers on the market today.

D-Mark makes a wide variety of granular activated carbon materials and has a great new website from which you can not only order their products but learn a great deal about the technology behind the carbon filter processes.
