Required - Supplied by Customer

this section lists required items that are not included with your carbon subscription or the industrial accessories package customers must supply the items listed below carbon approved equipment these are larger pieces of equipment that are necessary for the carbon workflow and must be purchased from outside vendors for more details, see facility requirements documents docid\ qvbccaueszszatj588zq1 \# item m1 / m2 or m3 / m3 max printer requirement l1 printer requirement 1 chiller x 2 oxygen supply (oxygen concentrator or oxygen tank) x solvents and fluids solvents play a critical role in supporting carbon processes be sure to have plenty of solvent in stock to prevent work stoppages \# item m1 / m2 or m3 / m3 max printer requirement l1 printer requirement 1 acetone (32 oz ) x x 2 ipa (isopropanol) 99% (4 gallons) x x 3 chiller coolant x 4 dpm (di(propylene glycol) methyl ether) 99% (10 gallons minimum, smart part washer customers only) x important these are the minimum quantities of isopropanol and acetone required for training and installation only you will need these items ongoing and in greater quantity for ongoing production notes coolants available for l1 printers 80% distilled water + 20% propylene glycol mix coolant sourcing dowfrost hd – premixed coolant is 80% distilled water and 20% propylene glycol (north america) dowcal 200 – can be purchased premixed (20% solution) or in concentrated form and mixed with distilled water by the lab (international) pekasol l – concentrated coolant that must be mixed with distilled water to form a 20% solution (international) the amount of coolant fluid required for l1 printers depends on a number of factors each l1 uses less than half a gallon of coolant fluid the chiller reservoir uses about 1 gallon the filter uses about half a gallon the rest of the amount needed will depend on the length of the tubing (ex the further the chiller is from the printer, the more volume of coolant needed) lab items \# item m1/m2 or m3 / m3 max printer requirement l1 printer requirement 1 liquid hazardous waste containers x x 2 trash container with foot pedal for hazardous waste x x 3 hdpe trash bags x x 4 ppe for each employee x x 5 power strip with surge protection x 6 computer to operate the printer x x if you currently have a computer that meets our requirements, you do not have to purchase an additional computer see computer specifications table below notes liquid hazardous waste containers consult with local waste management service for more information about the type of container needed to meet local regulations trash container with foot pedal for hazardous waste foot pedal enables hands free use customers may find that multiple containers are necessary hdpe trash bags chemically resistant bags used to line trash containers ppe for each employee safety glasses, gloves, and lab coats computer specifications the carbon printer user interface (ui) is accessed via a standard web browser interface your computer must be able to run a modern web browser and will need access to the internet and the carbon printer hardware printer software will run well on most contemporary computers (laptop or desktop) more complex models or larger quantities of models will require more robust hardware for an optimal user experience software the latest software versions are recommended as they typically incorporate important updates for enhanced security and optimized performance see the resources docid\ xckd87zq6nzxz3bsamccb document for more information faqs and additional information there are 5 disposable lab coats in the carbon provided accessories why do we need to purchase additional lab coats? the 5 disposable lab coats are provided for installation and training purposes after the training, they should be disposed of in your solid waste as they may have uncured resin on them they cannot be washed you will need to purchase lab coats for each technician working in the print area to protect their skin and body from uncured resin and solvent cloth lab coats can be laundered note you may want to consider contracting with a local laundry service to periodically launder your soiled lab coats what is an orbital shaker? an orbital shaker is a piece of laboratory equipment used to mix, blend, or to agitate substances in tubs or plastic containers by shaking them the shaker has a circular shaking motion and will agitate your parts to remove uncured resin from them the unit requires a standard electrical outlet dimensions 275 mm (10 8") w x 345 mm (13 6") d x 100 mm (3 93”) h what is a pour stand used for? a pour stand is a piece of equipment that will help you reclaim unused resin the cassette (the printer accessory that holds the resin when printing) is placed on the top of the pour stand to keep it stable once the cassette is in place, tilt the top of the pour stand forward and the unused resin will begin to flow downwards use a spatula to gently push all the unused resin downward a the funnel strainer and resin bottle capture the resin as it flows downward the funnel strainer captures any debris (small particles of partially cured resin), so the resin in the bottle can be reused if you have additional questions on the pour stand, please speak with carbon’s onboarding team mailto\ onboarding\@carbon3d com what is a chiller? the chiller removes excess heat from the coolant that is circulated through the l1 printer this keeps the printer cool and functioning normally supports up to 6 printers (60 hz model) what is the oxygen supply used for? when using an l1 printer, an external source of oxygen is necessary to supply the dead zone during printing customers can use an oxygen concentrator or oxygen tank an oxygen concentrator is a mechanical device that actively pulls oxygen from the ambient air it can supply up to 10 printers an oxygen tank is available in many sizes and is sourced locally
