3D Printing has become a passion of mine. One of my business ventures entails the use of 3D printing to develop prototypes of hard technologies, objects and working parts for entrepreneurs. I also work with schools to help them obtain 3D printers for their classrooms. As all schools have eliminated wood shop, metal shop and any type of mechanical equipment education, the 3D printer can now take the place of any or all of these now defunct instructional classes.
One of the great things about 3D printing is their ability to use over 50 different types of materials for making almost any object. The more typical filaments include ABS ( typical plastic used in Lego’s and most household items, PLA, a plastic made from corn starch and HIPS, high impact polystyrene. Of course you can now print with all types of nylon, carbon fiber, graphene, conductive, magnetic, poly carbonate and stem cells if you prefer.
Of the three most commonly used filaments, ABS has some distinct positives and negatives. It is very durable and has great compression and shear strength and prints fairly easily. The downside is the odor that is generated by the high temperatures required to melt the filament at the extruder head..usually 230 to 240 degrees C. Also, as the layers of ABS cool they tend to shrink a little and if the printer bed is not heated ( usually 110 dgrees C) and if there are cold drafts the print object can actually lift off the build platform.
To both minimize the odor and shrinkage issue, Pure Air Systems has created a prototype housing that will fit over almost all of the 3D printers on the market. The size was based upon the Aleph Objects Companies, Lulzbot TAZ 5 open source 3D printer. This is one of the more popular printers on the market has a fairly good size footprint. The enclosure has four sides including a swing over the top hinged front door for easy access to the entire print surface including the filament and it is all made out of plexiglass. On the top of the unit is a small compartment with a true carbon media filter and a small fan to very gently pull air from around the bottom of the enclosure to remove the odor but maintain the temperature of the interior of the enclosure above ambient by holding in the heat from the build platform. Thus eliminating the odor issue and keeping the ABS objects on the build platform and ending up with a better print.
Pure Air Systems makes a complete line of HEPA and Carbon based air filtration products for every market and is now 32 years old. Their expertise in ventilation, HEPA filtration and odor control will help them produce a product that is both high performing and lost cost. Look for more information on this new 3D Enclosure coming soon.
