ventilation and air quality ventilation equipment is not provided by carbon and can be a long lead item planning and installation should be started early in the site preparation process ventilation of carbon equipment ventilation options there are two options to consider when planning ventilation for your printer either option must meet the following requirements 1️⃣ fume extractors docid 95twe3ttl 5ihi6dnl4xi stand alone units two flexible hoses can accommodate two locations eg printer and washing workstation add more extractors as needed costs less than mechanical ventilation easy to install not compatible with 2 part resins ovens ( uv cure units ok) 2️⃣ built in mechanical ventilation fan driven flow of outdoor air which may include supply fans push outdoor air into a building exhaust fans draw air out of the building combination of both ductwork required consulting with a contractor may be required long lead time item, plan early reference general site prep docid\ kcxhddr fskysi32w63xn for more examples required for fp3d users for other questions about your specific ventilation situation, contact the onboarding team mailto\ siteprep\@carbon3d com requirements you must have either a fume extractor or built in mechanical ventilation that meets the requirements below before scheduling your printer installation printers item flow rate requirement additional requirements m1/m2 printer minimum flow rate 34 51 m³/hr (20 30 cfm) per printer printer exhaust outlet 4” diameter exhaust on the back of the printer m3 / m3 max printer minimum flow rate 34 51 m³/hr

4” diameter exhaust on the top of the oven ovens that require a condenser docid\ kcxhddr fskysi32w63xn will need additional ventilation capacity oven ventilation example your onboarding consultant will ask for a picture of each ventilation connection before scheduling the installation carbon recommends a \ central line \ of ventilation with \ multiple drops ,\ each with an installed \ blast gate \ and a \ 4" ventilation duct \ this will connect to the carbon product’s exhaust port using a hose clamp oven ventilation example 4" ventilation duct as oven exhaust temperatures can exceed 220 °c , use a flexible hose (and hose clamp) with a high temperature rating for at least 10 feet , such as this silicone hose example docid 95twe3ttl 5ihi6dnl4xi blast gate the blast gate regulates air flow in the ventilation system begin setup with the blast gate fully open (as shown in the image) check the oven's temperature against your resin's baking schedule if the oven does not reach required temperatures within specified ramp times incrementally, reduce the opening in the exhaust duct by pushing in the blast gate until the oven can follow the schedule accurately \ do not \ \ fully close \ the blast gate air flow must be maintained for example, if a step in the schedule requires the oven to ramp up from 200°c to 220°c in 1 hour, verify that it does exhaust adapter your oven is equipped with an adapter to connect the oven exhaust opening to the 4" ventilation duct attach the oven to the ventilation system using the provided adapter, which is shipped inside the oven the adapter is a flanged ventilation duct with an outer ring held with three wing nuts that should be installed on top of the oven you should connect it to the oven first so you can easily connect it to your 4" ventilation duct ensure the \ adapter sits tight to the top \ of the oven, without an air gap oven exhaust connection blast gate | adapter the oven exhaust connection should not have a gap at the adapter this gap prevents accurate measurements of oven air turnover this gap was formerly recommended by carbon if your adapter is connected in this manner, please adjust it to a tight connection checking temperature once the oven has been installed and ventilated, please conduct temperature checks, using any precision oven thermometer docid 95twe3ttl 5ihi6dnl4xi , at 60, 120, and 220°c to ensure your oven is maintaining the proper temperature condenser for high volume fp3d production if you will be using approximately 100 liters or more annually , you will need to install a condenser to prevent buildup in the ventilation ducting download the handout below for more information air quality printer must be installed away from sources of particulate matter smoke, dust from grinding, milling, sanding, or polishing, or any other known sources of dust or air contaminants (internal optical equipment is highly sensitive and will degrade when exposed to significant pollutants) room where printer is installed should have air filters to maintain air cleanliness above requirements do not apply to post processing areas ventilation capacity to test the air flow in your ventilation system, use an anemometer docid 95twe3ttl 5ihi6dnl4xi be sure it is properly calibrated you will need to estimate your ventilation tubing diameter, length, and bends to understand measurements for your lab example calculation the minimum ventilation requirement for a lab with a single m3 printer one m3 printer 20 cfm one part washing workstation (orbital shaker) 50 cfm one small convection oven 20 cfm is 90 cfm building capacity for excess ventilation is recommended to accommodate more printers and adopt future products or accessories without the need to re engineer your lab faqs and additional information how do we know if our installation site has adequate air quality? for most installation sites, air that is filtered and clean enough for workers not to wear dust masks will likely be adequate in addition, the printer must be separated from any machines that emit smoke, dust, mist, or particles for additional assurance, air particle counts may be tested to meet iso 8 classification, which provides acceptable particle limits for carbon printers can i use a stand alone ventilation system (fume extractor) instead of mechanical ventilation? yes, most dental customers purchase a fume extractor instead of installing mechanical ventilation to meet the site prep requirements however, there are several instances in which you cannot use a fume extractor the fume extractor is not compatible with the following non dental resins (carbon 2 part engineering resins) any oven other than a uv cure unit multiple m series printers (you will need more than one fume extractor) for more information on fume extraction, contact the carbon onboarding team mailto\ onboarding\@carbon3d com what are the trade offs between mechanical ventilation and stand alone ventilation? installation of mechanical (traditional) ventilation is costly and time consuming however, it is a more effective option if you are currently using or plan to use multiple printers or additional equipment that requires ventilation the fume extractor is recommended for single printer sites that do not plan to add additional equipment it is relatively low cost and will meet appropriate health and safety requirements carbon has validated the following stand alone ventilation system sentry air systems model # ss 400 fsd https //www sentryair com/brochures/ss 400 fsd pdf do i need a contractor for traditional/mechanical ventilation? in most cases, you may want to use a contractor to install mechanical ventilation a contractor can help ensure that your ventilation system meets all local and regulatory codes, as well as carbon recommended specifications why does carbon have a ventilation requirement? carbon printers require ventilation because liquid resins and solvents are classified as hazardous materials without ventilation, your facility could be exposed to fumes that could pose a health risk for your employees for more information regarding health and safety, contact your local regulatory agency electricity power plug in a wall socket in a lab requirements you will be required to supply power to the following equipment and accessories m1, m2, m3,
