ventilation and air quality requirements ventilation equipment is not provided by carbon and can be a long lead item therefore, planning and installation should be started early in the site preparation process you must have built in mechanical ventilation that meets the requirements below before scheduling your printer installation this must include a blast gate/damper for each drop to control the amount of airflow 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 (20 30 cfm) per printer printer exhaust outlet 4” diameter exhaust on the back of the printer l1 printer minimum flow rate 85 m³/hr (50 cfm) per printer printer exhaust outlet 4” diameter exhaust above the printer smart part washer 85 m³/hr (50 cfm) per part washer spw exhaust outlet 4” diameter exhaust on the back of the spw custom distiller (if applicable) 170 m³/hr (100 cfm) per distiller fixed snorkel only for use with vf 1 solvent (formerly vertrel solvent blend ms 767 3d 13) not compatible with dpm or daa solvents convection oven 34 m³/hr (20 cfm) per oven convection oven exhaust outlet 4” diameter exhaust on the top of the oven part washing area (orbital shaker) 85 m³/hr (50 cfm) per wash area adjustable snorkel or fume hood facility 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 total ventilation capacity m1 / m2 & m3 / m3 max printers the minimum ventilation requirement for a single m1/m2 or m3 / m3 max printer lab plus the industrial accessories (orbital shaker and convection oven) is 153 m³/h (90 cfm) the minimum ventilation requirement for a single m1/m2 or m3 / m3 max printer lab with a smart part washer and industrial accessories is 238 m³/h (140 cfm) capacity calculation for the above lab ventilation needed (140 cfm) = m2 printer (20 cfm) + smart part washer (50 cfm) + convection oven (20 cfm) + orbital shaker (50 cfm) l1 printers the minimum ventilation requirement for a single l1 printer lab plus the industrial accessories (orbital shaker and convection oven) is 204 m³/h (120 cfm) the minimum ventilation requirement for a single l1 printer lab with a smart part washer and industrial accessories is 289 m³/h (170 cfm) capacity calculation for the above lab ventilation needed (250 cfm) = l1 printer (50 cfm) + smart part washer (50 cfm) + convection oven (20 cfm) + orbital shaker (50 cfm) building capacity for plenty of ventilation is a good idea for your carbon lab because excess ventilation will make it easy to accommodate more printers and adopt future products or accessories without the need to re engineer your lab if you do not have a meter to test the flow, we have used this anemometer be sure it is properly calibrated you will need to estimate your ventilation tubing diameter, length, and bends to understand the pressure drop for your lab ventilation locations ventilation is required in 3 places in a single printer lab printer part washing workstation convection oven ventilation is required in 4 places in a single printer lab with a smart part washer printer part washer part washing workstation (orbital shaker) convection oven each additional product will require 1 additional ventilation drop per the ventilation requirements table (see above) each of these locations must be vented to the outside of the building note the smart part washer with dipropylene glycol methyl ether (dpm) solvent does not require separate ventilation since dpm can't be distilled and thus requires no custom distiller the custom distiller is only applicable if you plan to use your smart part washer with vf 1 (formerly vertrel™ solvent blend ms 767 3d 13) see the table below for solvent/material compatibility smart part washer solvent compatible materials vf 1 (formerly vertrel™ solvent – ms 767 3d 13) uma 90, rpu 70, fpu 50, epu 40/41, and sil 30 dipropylene glycol methyl ether (dpm) epu 40, epx 82, fpu 50, mpu 100, rpu 70, sil 30, and uma 90 ventilation examples your onboarding consultant will ask for a picture of each ventilation connection before scheduling the installation we recommend a central line central line of ventilation with multiple drops multiple drops , each with an installed blast gate blast gate and a 4 inch diameter ventilation hose 4 inch diameter ventilation hose this will connect to the carbon product’s exhaust port using a hose clamp m1/m2 & m3 / m3 max printers smart part washers rear view of oven with adapter wash area with adjustable snorkel located over orbital shaker and solvent filled container l1 printer (top view showing circular exhaust port) ventilation hose attached to l1 printer ventilation system behind l1 printer snorkel over custom distiller for vf 1 (formerly vertrel solvent blend ms 767 3d 13) additional oven ventilation notes your oven is equipped with an adapter adapter to ensure flow rate is not too high please 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 inch round exhaust duct do not seal the outer ring (a common customer issue) this arrangement pulls air from the room rather than sucking heat out of the oven, but in doing so also removes oven fumes the blast gate blast gate regulates air flow and should not be completely closed or completely open as oven exhaust temperatures can exceed 220 °c , use metal duct or metal duct hose metal duct or metal duct hose , plus a hose clamp, to withstand the high temperature air for at least 10 feet to allow for sufficient cooling you can also use a flexible hose with a high temperature rating, such as the silicone hose from mcmaster carr (pictured above) once the oven has been installed and ventilated, please conduct temperature checks, using any precision oven thermometer , at 60, 120, and 220 °c to ensure your oven is maintaining the proper temperature epu resins and lauryl methyacrylate (lma) lma notes a potential fire risk exists if you operate your oven at temperatures in excess of the carbon recommended bake profiles this concern is specific to ovens used to cure epu parts lauryl methyacrylate (lma), which is released during the baking of epu parts, can condense inside oven insulation and/or ducting the amount of lma released will be dependent on the volume of epu parts in a particular bake and how often you are baking with those parts this condensed lma can ignite if exposed to temperatures above what is needed to cure the parts please refer to the sds for lma for more specific information about this chemical given our findings, we are updating our user documentation to include these additional recommendations for customers who print with epu resins don’t perform bakes at higher temperatures than the bake profile specified by carbon inspect oven and exhaust ducts for presence of condensate if you find condensate, clean it or replace ductwork refer to the sds for lma prior to cleaning to ensure proper precautions are in place if condensate is noticed after cleaning or replacement, a heat exchanger may need to be installed to cool the ventilation duct to remove the condensate additional recommendations consider baking ce/epx and epu parts in separate ovens ce and epx require a higher temperature to bake clearly label ovens with maximum allowable temperatures for bakes as specified for products by carbon do not exceed the carbon recommended bake temperatures yamato ovens are equipped with independent overheat protection refer to the consult your facilities and ehs staff on proper handling of lma condensate in the exhaust system and proper personal protective equipment for handling of lma contaminated exhaust components and associated ductwork reminders ventilation must vent to the outside of the building m1/m2 & l1 printers only before scheduling the installation, you must provide photos of each of the following ventilation connections printer; part washing workstation (orbital shaker); convection oven; as well as smart part washer and custom distiller, if applicable ensure the oven ventilation is installed using the provided adapter (shipped inside the oven) check the flow rate of each connection prior to equipment installation check the oven temperature after ventilation installation each ventilation drop must include an installed blast gate to tune airflow have extra hose clamps on hand for exhaust hose connections selecting the proper type of ventilation hoses at installation may save you headaches later building capacity for plenty of ventilation is a good idea for your carbon lab because excess ventilation will make it easy 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 can i use a stand alone ventilation system (fume extractor) instead of mechanical ventilation? no, the fume extractor is not compatible with the following non dental resins or carbon 2 part engineering resins if using multiple m1/m2 or m3 / m3 max printers with 1 part resins, you will need more than one fume extractor for more information on fume extraction, contact the carbon onboarding team 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 in a single printer lab with a smart part washer, how many ventilation drops are required? ventilation is required in four places printer, smart part washer, part washing workstation (orbital shaker), and convection oven see the table above for the specific flow requirements per product if using a custom distiller (only for vf 1 formerly custom vertrel™ solvent ms 767 3d 13), this will also require ventilation where is the exhaust port located on l1 printers? on the top of the printer where is the smart part washer exhaust port located? on the back, in the upper right corner 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 oven ventilation lma faqs what are the elements of a ventilation system set up to capture condensate? lma fumes tend to condense in cold spots in general, this seems to be in areas of the ventilation system where the hot air coming out of the ovens cools elbows, connectors, etc further away from the oven carbon has installed cold traps at the point where oven ventilation connects to the main facility exhaust line these cold traps condense lma and the liquid can be collected and disposed of as hazardous waste work with a qualified hvac contractor to determine the size of the intercooler/condenser unit to best suit your needs how do i safely clean out existing ductwork if condensate is present? if you notice condensate in the duct connecting to your oven exhaust we recommend you replace any flexible ducts with new ones for condensate that might have accumulated in metal pipes, use a rag to wipe down the inside of the ductwork as far back as possible any cleaning gloves, wipes, rags etc the come in contact with lma should be handled as hazardous material and disposed of accordingly what ppe is needed during this cleaning? standard ppe used for work with resins and solvents should be used for this cleaning task how do i handle multiple resin bakes in ovens? per the memo and user guide, avoid baking parts printed with epx in the same ovens as epu parts epx resins require a higher bake temperature electricity requirements you will be required to supply power to the following equipment
